Making babies, the best way!Some couples get pregnant easily. But many couples have to wait months before the baby is conceived. There are several factors that affect conception right from fertility to the position during intercourse. Some believe that positions have nothing to do with conceiving a child. This is not true. Some positions are ideal to help the sperm meet the ovum. Let's see what some of these positions are. Missionary position:The best position for getting pregnant fast is the missionary position.Here the man is lying on top of the woman allowing for the deepest possible penetration, making it possible for the sperm to get deposited closest to the cervix. It is also the most common and comfortable position preferred by couples. Raise your hips high: Your hips have a lot to do in helping you get pregnant. Raise your hips high during sex by placing a pillow below you. This helps to expose the female cervix to as much semen as the male can release. Doggy position: Considered to be the most erotic and pleasurable position,this rear-entry position where the man enters the woman from behind is also recommended for increasing the chances of getting pregnant. In this position too, the sperm is deposited closest to the cervix, thereby increasing the chances of conception. Side-by-side: You can also try having intercourse while lying side by side. This position, likewise, causes the most exposure of the cervix to the male sperm. While these positions certainly improve your chances of getting pregnant, there is no guarantee that you will conceive. The most important thing is to enjoy this special time and have fun with your partner. So keep enjoying and keep trying!
Pediatric diet formula food vs traditional foodAccording to the World Health Organisation, it is unnecessary to give your baby rice cereals at the age of four months as breast milk can provide all the nourishment a baby needs in the first year. No other solid food is required. Breast milk has all the nutrients like fats, protein, cholesterol, carbohydrates, vitamins and minerals which are required in the first year of life. According to most studies,formula foods are not the healthiest option to begin solid foods on. Doctors prefer that babies be given boiled vegetables and mashed fruits like bananas and not formula cereals that contain simple carbohydrates. It is not a good idea to give babies processed and refined foods that are found in all formula foods. Formula foods do have nutrients, but they are not as easy to absorb as nutrients from foods prepared at home. You can also ensure quality in food that is prepared at home. Formula foods cannot imitate the natural taste of foods. Babies like to choose foods according to taste just like the adults and you can give them a wide variety of choices like offering them different fruits and vegetables rather than the similar tasting formula. You will be surprised to know that mother's milk has the taste of the foods she eats and so babies develop taste for a variety and may like the insipid taste of formula. Another reason why formula foods may not work that well is that they contain cereals. However, the enzymes that are required to digest carbohydrates are not fully developed in babies until they are more almost three years old. Cereals and breads are very difficult for babies to digest. Undigested grains can throw off the balance of bacteria in the gut and this is the reason for a lot of digestive issues once they are grown up. Solids should not be introduced until six months of age, as studies now reveal that if solid foods are given early on then it increases the likelihood of allergies, especially of those foods introduced. Babies produce only few enzymes and digestive juices that are mainly required to digest protein and fats. This is because mother's milk has 50 to 60% healthy fat which is a must for the babies' mental and physical growth. Most baby infant nutritionists feel that formula feed is not a complete food. Babies will get deficiency,such as iron, as it is difficult to absorb them from formula foods. The debate continues as many feel that the marketing gimmicks are what selling these foods and not the nutritional value they provide to babies. A note of caution, excessive amount of juices are harmful for babies as these can lead to obesity.
Teenage troubles for autistic kidsTeenage brings along with it a lot of physical and psychological problems. Your body undergoes a lot of changes, the way the world looks at you is changing and you are not in the position to accept all this. Teenage is one of the most painful periods in one's life.  For an autistic child teenage can be compared to living a nightmare day in and day out. Here is a look at the problems of teenage from an autistic kid's point of view: Social Interaction The ability to interact socially is absent in autistic kids. They are loners who prefer to be left alone and undisturbed in their own worlds. Such a child is a natural target for bullying and ragging by other kids of his age group. At times even if the autistic child wants to come out and make friends, he is not able to do so due to lack of the required skills. Teenage is a period where you need at least one friend to confide in. It can be an extremely difficult phase when you are all alone. Puberty This is the dramatic time in life dilled with hormones and emotions. Your body undergoes lots of changes and you are confused about so many things. You don't know whom to ask or whom to turn to for guidance. Autistic children do not have the maturity to understand this phase. Special issues for autistic teens and sexuality include: Knowledge of physical changes in body. Knowledge of 'good' and 'bad' touch. Ability to communicate about a 'bad' touch or action. Keeping 'safe' distance from others. Handling menstrual cycles. Avoiding 'self-touch' in public. It can be a phase of emotional turmoil for the parents. They need to work closely with their child's special teachers to chalk out a plan that will be best suited to the child in handling puberty successfully. Self-help skills Simple self-help skills like hygiene can be a challenge for teenagers with autism. Improper motor skills, compliance, and sensory problems may interfere with a teen's progress. The proper training of hygiene and grooming can help to add these elements into the daily routine. The right approach is to simplify each task into simple small steps. The positive reward system is a great source of encouragement, as positive motivation always help the teenagers. Higher Functions Autistic teenagers are socially awkward. They lack the power to comprehend and process complex social cues which includes sarcasm, body language, humor, emotional responses and facial expressions. What complicates the problem is that the autistic child lacks empathy and hence may appear rude. Such kids are likely to be teased a lot in school settings.
Cleanliness - A clean body, clean mindPhysical Benefits: Killing of Germs: Disinfecting your living area allows negligible scope for breeding and spreading of germs and bacteria. Though not visible to your eyes, many of these can cause severe illnesses. Prevention of Food Contamination: Clean cooking utensils and counter tops allow for low risk for contamination of food. The parts of the utensils which have come in contact with fish, raw meat, or eggs are recommended to be washed with hot water and soap. Make sure you wash your hands to avoid spreading of any bacteria in your house.  Keeps Illnesses and Allergies at Bay: Many allergies could be caused due to dirty mattresses, carpets, sheets, walls, and furniture. In order to keep away mold, dust mites, cobwebs, and mildew, make sure you dust, mop, and vacuum the house on a regular basis. The sheets should be washed at least once a week with hot water and detergent. Floors and walls, wardrobes, and refrigerator should be cleaned using disinfectant sprays up to 2 to 3 times per month. Thoroughly clean your carpet and upholstery at regular intervals. Psychological Benefits: Association of Non-Cleanliness with Moral Lapse: In a review by Current Directions in Psychological Science, it has been found that physical cleanliness does not only physically benefit a being, it also results in weighing the person on a moral radar. When we perceive a physical contamination, we respond in the same way as we would in case of an act of moral disobedience. This response includes repulsion and disgust accompanied by their behavioural components like scowling and frowning. Sense of Accomplishment: Those who clean their house and living space have been found to have a consequent sense of accomplishment that adds to the way one feels about oneself. Clarity and Organization of Thoughts: It has been discovered that those living in a clean and neat environment tend to have a greater capacity to think than those who live in a messy and unclean atmosphere. Proactive Sanitation Teaching for Children: Start with your own home. A child emulates its parents, and if the parents practice cleanliness as part of their lives, children would notice and follow suit. Children tend to connect who they are with their home environment and as they grow up they ensure that such a cleanliness of their world around is maintained.  towards their immediate surroundings, thus ensuring that they do not contribute towards pollution and environmental degradation, at least on an individual level.
Lost in wonderland? - Absentmindedness!The Daily Telegraph reports that on an average every adult in UK forgets three things per day. Forgetfulness is a human tendency. If this absentmindedness or forgetfulness is limited to forgetting three to five things per day, then it can be left unattended. However, if you or a near one is facing a lot of trouble in your daily life due to this habit or problem, you should immediately have a consultation with your doctor. Mystery behind Absentmindedness According to Maria Jonsdottir, an investigating neuropsychologist from Iceland, absentmindedness is the mental lapses that usually happen in connection with the actions that are routine or well-rehearsed. You can perform these actions without any need to be careful. This includes regular actions such as squeezing out toothpaste or moisturizer from the tube. These action slips are very common and if you observe carefully, you do forget some such regular things every day unknowingly. Psychologists believe that an individual makes such mental lapses around 30 times in every week. On an average, the nervous system of a human brain runs quite efficiently. However, sometimes temporary fault may develop that may make you use incorrect word or slip to your native tongue while conversing. This does not mean however, that something is wrong with your brain. When the team of Jonsdottir surveyed around 200 people, they found out that on an average the slips are 6.4 per week although the number also greatly depends upon the gender, intelligence level, and age. One startling fact that was discovered is that most of the events of forgetfulness occurred before 8 p.m. that means people tend to forget more during the daytime than in the evening. Apart from a momentary lapse in the functioning of brain efficiency, other reasons that can lead to increase in the incidents of forgetfulness are high stress levels, mobile phones, e-mails, and busy lifestyles. Today, people are pressed for time and they have more work at hand than time and that has increased the occurrence of forgetfulness. Types of Absentmindedness A team of neuropsychologists has divided these mental lapses into five categories. The most common are the storage failures in which people cannot recall what they had planned for a particular occasion or they can recall the action, but cannot remember for whom it was meant. Another category is test failures in which people come back home to check whether they have turned the light off and find out that they have already done so. Discrimination failure is another category of absentmindedness wherein you for a moment fail to identify the difference between your things and others'. During the study, a male participant accepted that he picked up the jacket of his female partner thinking it to be his own. Sometimes you put books in the dustbin and the trash on the shelf and laugh at your behavior a moment later when you find out what you have done. This is discrimination failure. Another mix-up includes program assembly failure wherein you put salt in the tea instead of sugar or you just do not keep the right things at the right place. The fifth one is the sub-routine failure wherein you go to the market to buy tea and instead come back home with coffee. The research proves one thing that if you are absentminded, it does not mean that you have a bad memory or can suffer from dementia as is widely publicized in the media. It is perfectly all right to forget or being an absentminded person. Sometimes the incidences of absentmindedness can increase due to fatigue. A good sleep and rest can fix the problem easily.
5 cardinal sins for the skinWhile cigarettes may not constitute food in the strictest sense, it does have a profound effect on skin complexion, health, color and tone. We eat that we may live, but sometimes we eat way too much and consume stuff that may be extremely hazardous to our health. Since we are talking about skin, here are 5 most hazardous foods for your skin: Grease adds to the crease Since healthy skin is all about healthy blood circulation, any food which is likely to clog up the blood vessels internally is deemed bad for skin tone. Packaged snacks like potato chips may have edible oil written in bold but this contributes significantly to the slowing down of 'collagen and elastin syntheses' which in turn causes the skin to appear aged and all wrinkly. The french fries that we consume as a TV snack can also cause an acne outbreak on the skin and face. Gluten Glutton Gluten is a substance found in wheat and other food grains. We may not even be aware that some of the food grains have gluten as a main constituent. Gluten intolerance can also cause inflammations on the skin in the form of rashes or acne. Bad news is that the pizzas, pastas, cakes and bread that we get off the rack may be heavy in gluten (Surprised that they don't say that on the pack) and that may be the reason for you to lose precious skin tone. So seek gluten free foods, though that might not be the easiest of tasks, but for your skin, it certainly will be worth it. Caffeine - the skin coffin If you are one of those coffee addicts then you may as well write an obituary column lamenting the loss of your skin tone and complexion. It's not without reason that health freaks love bashing coffee beans and caffeine rich beverages, as they are truly hazardous. How? Studies have proven that just 2-3 cups stimulate pituitary-adrenocortical response. Yes, but what does that have to do with your skin? Well this leads to the hormone cortisol to increase in our bodies. Cortisol is known as the stress hormone! So now here's what it does to your skin -it accelerates the ageing process which means wrinkled skin and causes dehydration causing the skin to show an unusual pallor. So before you turn the coffee faucet on think twice. Fad to Black How fad diets are not skin friendly? Some people go on a high protein, low-carb diet which could sound the death knell as far as complexion goes. Dieting depletes calcium levels, which means your bones are going to suffer and what's the point of having skin on bad bone density? Besides low-carb diets can utterly wreck the complexion as the delicate PH balance in the skin is ruined. Some of the meat, poultry and dairy products too can have artificial chemicals injected in them which cause a hormonal imbalance in our bodies leading to skin disasters. Fruits and vegetables have chemicals injected too sometimes! Beware! Cereal Killers Cereal killers are those people who ignore the need of a proper diet for skin health. So anybody who indulges in too much sugar, caffeine and greasy food stuffs is a 'Cereal Killer' A lack of cereals in the diet can literally kill your skin. Cereal foods have high fiber and antioxidants for moisturizing the skin and protecting it from skin damage. For great skin other than cereals which are simply fabulous for keeping skin hydrated and breathing easily, one can eat fruits, olive oil, healthy fats, almonds, tofu, grains, nuts and the good old vitamin B rich products. Ceramides in raw food diets, organic foods, wheat germ and brown rice protect the epidermis of the skin and make it impervious to external attacks and pollutants while maintaining their tone and beauty.
Muscle build up dietYou may think that you need fatty foods to bulk up, but this is not true. Fatty foods will do just that make you fat. Lean meats, fruits and vegetables will actually build muscle. Take a balanced diet of vegetables and lean meats to achieve your muscle building goals. Changing your diet to build muscle will help with your overall health. Eating food that helps build muscle will ensure that you are not wasting all that hard work you are doing in the gym. Workout utilizes considerable energy. Food is the only way to replace this energy. So what happens if you fail to eat the right type of food to build muscle mass? It will take longer to build muscle, and it may even prevent muscle building altogether once you reach a certain point. Is protein important or not? You bet it is. Protein provides the building blocks to build that muscle. What types of protein are best? Chicken, eggs, steak (with the fat cut off), fish, cheese (especially cottage cheese), and nuts are all great sources of protein. Finding out how much protein to eat when you are interested in building muscle fast is actually not difficult. First, you will need to find out your lean body mass weight in kilos, and then you simply multiply that figure by 2.75 to determine your daily protein requirement. Calculating your lean body mass uses some complex formulae, so ask a professional at the gym if you do not already have this figure. Carbohydrates, in moderation, are also essential when finding foods that build muscle. Do not eat too much, though, unless you choose high fibre carbohydrates, and then you can indulge in much larger amounts. High fibre carbs include rice, potatoes, oatmeal and bananas. Reducing fat in your diet is of course necessary to build bigger muscle on a body that appears lean and has a low body fat ratio. If you are focusing on what foods build muscle mass, you also need to bear in mind that it pays to reduce fat as well. Although proteins are essential, it is really important to select proteins that are low in fat, or that you can cut the fat off. So eat your chicken without the skin, and go for lean steaks rather than more fatty cuts of meat. Opting for cottage cheese or other reduced fat cheeses, and low fat milk also helps reduce your fat intake. You may argue that drinking has no effect on what to eat to build muscle. But you would be wrong. Hydration is critical to general health and wellbeing. Two litres of water a day is what most experts recommend for maintaining optimal health. To drink that amount, you need to drink up to 12 glasses of water a day, which is quite a lot. So start early in the day, and space your water consumption out throughout the day. Foods that build muscle are great and an essential component of your bodybuilding program. But do not be lulled into a false sense of security and think you can slow down on your workouts. Both bodybuilding exercises and bodybuilding diets are required to get a body to die for as quickly as you possibly can. Even if you are working on improving your physique slowly, you should combine a bodybuilding diet with bodybuilding workouts for best results. Sample Diet: 7:00am: Breakfast: 4 eggs + toast or oatmeal + milk with protein powder mixed in (a lot). 9:30am: Snack: 1 Meal replacement supplement + milk. 12:00: Lunch: Tuna sandwich (1 whole can) + green apple. 3:00pm: Snack:  2 Meal replacement supplement + milk. 5:30pm: Workout: Have water (or carb drink if you want), within 30 mins of end of workout (on workout days only) Meal replacement supplement + milk. (If you are going to have Creatine - put it in this Meal replacement supplement at the end of your workout). 8:30pm: Dinner: A chicken breast (aprox 8 oz + some rice or other starch carb + if you want also eat some veggies) Before Bed:  Meal replacement supplement + milk.
Aids defining cancersIn fact the presence of such aids defining cancers is an indication of advanced AIDS having developed in these patients. However, the reasons for these cancers are unclear. It is possible that since people with AIDS have low immunity, they become more susceptible to these cancers. The double attack of these already complex diseases complicates treatment plans too. Thus, it needs care under experienced doctors who specialize in these diseases. The cancers that define AIDS are: Kaposi's Sarcoma:This is a type of skin cancer. It was usually found usually in people who have received organ transplants. Nowadays it is also most prevalent in homosexual men with HIV/AIDS and is also called epidemic Kaposi's Sarcoma.  It causes lesions to show up in multiple points in the body such as skin, lymph nodes, liver, lungs, spleen and digestive tract. Non-Hodgkin Lymphoma:This is the second most commonly associated cancer with HIV/AIDS. The various sub types of NHL are primary central nervous system lymphoma and primary effusion lymphoma. Approximately 4-10% people with HIV/AIDS develop NHL. Other kinds of cancers are anal cancer, liver cancer, mouth cancer, Hodgkin's lymphoma, testicular cancer, melanoma, throat cancer, colorectal cancer and multiple skin cancers.  Treating Cancer in HIV people: Till anti-HIV medication were not discovered the future for infected people was bleak. They were already sick and their bodies weak even before their cancer treatment were started. Presently the cancer treatment is mixed with anti-HIV drugs. However, depending upon the extent of cancer and the need of AIDS care, variations are made between chemotherapy and other HIV related drugs needed. Treating Kaposi's Sarcoma: Often anti-HIV drugs are enough to treat this cancer. The lesions, which are viral, shrink, as the immune system gets better. Sometimes chemotherapy and radiation may also be needed if the lesions are internal. Treating Non-Hodgkin Lymphoma: AIDS related NHL is fast growing and needs intense chemotherapy treatment. Introduction of highly active anti-retroviral therapy and use of drugs that help the infected body make new blood cells has relieved a major concern for HIV patients where previously due to their low blood cell count, chemotherapy could not be administered to them. But with these advances, acutely monitored chemotherapy treatments can be administered now. Treating Cervical Cancer: In case of women who have a good immune system and invasive cervical cancer can still be treated similarly as non-HIV women. They can even do well in surgeries and other conventional treatments. Discovering Cancer Early: Screening helps discover presence of cancer when no symptoms are evident. However AIDS defining cancers cannot be detected through screening. Thus, close monitoring, regular checkups and a keen lookout for symptoms of these cancers can help discover the ailment if present. Pap tests help discover cervical cancer in women. However, in case of HIV women, these should be undertaken more often. Even as often as 2 tests a year, 6 months apart in the first year of HIV detection. If the tests are clear, they should get Pap tests done regularly once a year henceforth. For other AIDS related cancers, the screening tests are still being devised. Lowering Cancer Risk: HIV ruins the body's immune system making it susceptible to a variety of diseases. Good health practices are a must for those detected with HIV in order to ward off cancer. They should surely not smoke or consume alcohol. Injection drugs and unsafe sexual practices also pose increased threat of cancer. Maintaining balanced diets, physical activity and proper body weight are extremely important and helpful too.
Some tips to prevent night blindnessHere are some foods and eating tips, which will help improve vision and prevent night blindness: Eat dark green leafy vegetables like spinach and collards. These contain high amount of lutein and zeaxanthin, the nutrients for healthy eyes. Do not smoke. A glass of red wine daily is fine but drinking is not. Stay away from hydrogenated oils, refined carbohydrates and sugars in excess. Always wear sunglasses while going out in bright light to avoid potential sun damage to eyes.  Amber and grey-coloured lenses are effective against ultraviolet rays. See an eye specialist and get prescription glasses for driving at night, if required. Do not ride in dim light at night and see if you can postpone the work until next day. Even good lighting conditions at night even in a big city, can be troublesome to someone with night blindness. Vitamin A rich foods like spinach, carrot, papaya, broccoli, and mangoes should be added to your daily diet. Fish oil is a great source of vitamin A. Cod-liver oil is used as medicine too. Some wild plants are said to be rich in vitamin Abut they are seasonal, available in small quantities and there isn't much known about them. Beans are another fairly common source of vitamin A. These are consumed especially during autumn. Eggs are a good source of vitamin A. Eat eggs daily. People with high cholesterol should, however, limit their egg intake. Hot pepper is contains vitamin A too, but the preservation method, sun-drying, decreases the vitamin A content. Carrots are another good source. They are high in vitamin A and arenot expensive as well.
How to talk about STDsThese are dangerous times that we live in. Just the sheer number of people affected by sex related problems, diseases and conditions all over the world is simply terrifying. AIDS, venereal infections like syphilis and gonorrhea, herpes, HPV etc. are rampant and it calls for some responsible sexual behavior. However, that's a utopian world where humans will be monogamous and will behave responsibly. Even single people might get exposed to these diseases through indulging in risky sexual contact. Imagine doling out $750,000, as a woman in the US got from her husband because he gave her herpes. Even if you are not held legally accountable, what about moral responsibility to own up and discuss a possible STD infection with your partner! Take the case of Jack a happily married man for ten years who had casual sex when out of town on an official trip. He showed no obvious symptoms of any infection but in a month, his wife showed signs of herpes and his marriage crumbled as his wife struggled to come to terms with her husband's obvious infidelity and his callous manner in exposing her to a serious sexual infection. Call it ignorance but sometimes a person might engage in sexual intercourse and contract a disease which he might even not be aware of until the symptoms start appearing. (Refer article on Syphilis on www.topdoctorsonline.com) By then, he might have, in all probability, passed it on to his regular sexual partner or spouse. Or perhaps, there is another possibility that the person knows that he has contracted a sexual infection but doesn't know how to break the news to his partner.  If a person is aware of his infection, yet exposes another person knowingly, it is akin to premeditated murder. Yes, it is going to be a difficult thing to tell your partner which might even signal the end of the relationship or cause severe strain on it. So, if you are caught in a situation like this, what would you do? The option would be to visit a sex therapist and confide in him and then take an appointment for both and let the professional break it to the partner. That is of course if you are in a stable relationship. For those who both party to casual sex, the infected person generally won't be that open about his infection and may even choose not to care particularly if the other person is a complete stranger. A report in MedlinePlus news reveals some more shocking statistics: Many people said they occasionally, rarely or never got tested before having sex with casual partners (50 percent) or long-term partners (39 percent). Of the people who did discuss STD testing, very few discussed concurrent sexual partners or when partners' testing occurred in relation to their last sex act. Only half explained what types of STDs their partner had been tested for. These issues are important components of assessing STD risk, the researchers said. About one-third of participants reported telling a partner they didn't have an STD even though they hadn't been tested since their last sexual partner. One U.S. woman was awarded $750,000 in court from her ex-husband because he gave her herpes, and the legal trend is to make people accountable. (http://www.dummies.com/how-to/content/how-to-talk-to-a-partner-about-stds.html) Remember even wearing a condom is not a 100% guarantee that the infection won't pass on to the other person but that's the least that you can do if you don't have the courage to spill the beans about your condition. If you feel that your partner may be indulging in sexual activity with multiple partners and if you feel he might be infected, then you are well within your rights to decline to have sex with him until he/she gets tested. If you notice sores around the genitals do not indulge in oral or anal sex or any kind of sex and insist on a condom always; it could save your life.
Importance of sex educationOur society is beset with a lot of myths about Human Sexuality and hence the family relationships are affected adversely. A man is considered (mistakenly) as a man only when he performs effectively in bed. In other words a man hangs his self-esteem on his male organ. Hence whenever there is a problem in performing sex, he becomes frustrated and depressed. In order to cover up his inadequacy he may blame his wife for his problems. This attitude will adversely affect the martial relationship, leading to unhappiness in nonsexual aspects of marriage. He may become violent when the wife retaliates. Marital break down, even if not ending in legal separation will be a very messy affair. Sexual behavior is determined by information or knowledge one has on hand and the parameters of comfort zone. Unfortunately we are dealing with a behavior that is besmirched with myths and misconceptions, and a breeding ground for stigmas and taboos, which leads to unhealthy sex life. These barriers have to be broken; otherwise healthy sexual and family life cannot be achieved. It is guesstimated that one in every three couples have some sexual problem or other and they do not know how and where to seek help. The media gives them anonymity and guides them in proper direction. The three main enemies of sexual satisfaction are guilt, anxiety and fear. All these stem from ignorance. Due to the stigmatization sex education is not available. Hence the streets have become not only the libraries for knowledge on sex but also the laboratories. When one of the dimensions (recreation) becomes problematic it impacts the health of the other two dimensions (procreation and relation). Magazine columns endeavor to dispel sexual ignorance and empower people with scientific knowledge. The aim is twofold: First, to inform in simple language, the scientific aspects of sexual problems and clarify myths surrounding sexuality; Second, to help people become comfortable with their own sexual life and elaborate on various treatment options available. People will thus be empowered to take responsibility for their own health and happiness. Have an open mind. All dimensions of human life are important. To consider one as unimportant and attach a stigma will hamper the development of the full potential of an individual. Understanding sexuality will enrich our lives and relationships.
