Can a man be depressed?
The ultimate checkup: Checklist for men
What causes male balding?They say there are 3 types of men: the ones that go bald at the top are thinkers, the ones who go bald at the back are lovers, and the ones who grow bald at both places... only think they are lovers. If pregnancy and menstruation are a female's burden, then baldness is a great inconvenience to men. Some men lose their hair in their youth and thus lose their confidence along with their hair. So what is with baldness and men? Men start having a receding hairline by the time they hit 30, though it could begin in their 20s as well. The most common type of baldness is the mid-frontal type resembling a horseshoe. Earlier it was thought that baldness is caused only by genetic factors, but apparently emotions, lifestyle and diseases also contribute largely to hair loss and baldness. This hair loss can be temporary or permanent. Some medications like anticoagulants, antidepressants, antifungal medicines, chemotherapy etc can cause baldness. Certain diseases like thyroid disease, Crohn's disease, lupus can cause hair loss and baldness. Poor nutrition is an important factor in hair loss. Vitamin and mineral deficiencies along with poor nutrition can pave the path sooner than most other things. Then there are some conditions like Alopecia Areata which cause baldness in patches -- on the head or beard. It is temporary and the hair grow back in about 6 months to 1 year. Corticosteroid injections are used to treat the condition. Air and water pollutants, environmental toxins, conventional styling products have the potential to build up on the scalp. These affect hair cuticle, cause dryness, and weaken the hair causing them to easily break off before their natural lifecycle has ended. If you notice your hairline receding more than usual, then check if you are getting enough nutrition. Exercises like the headstand and handstand send the blood rushing to the scalp and can help with hair growth. Massaging the head with warm oil helps to increase blood circulation as well. Use a shampoo that suits your hair along with a conditioner. Oil your hair overnight at least thrice a week. Keep yourself well hydrated and try vitamin C which can help arrest hair fall. Use a clean comb and ensure that you sun your scalp, as vitamin D is an essential tonic for skin, bones, teeth and even hair.    
Prostate cancer- Things you must knowSymptoms include: Frequent urination, especially at night. Difficulty in starting and stopping urination. Weak and interrupted urine stream. Pain or burning at urination and ejaculation. Blood in urine or semen. Growing older is the greatest risk factor. Risk increases after age of 50 and in men with family history (father or brother with prostate cancer). Prostate hypertrophy, too much sex, or masturbation does not increase risk of prostate cancer. Digital rectal exam (DRE) helps to detect cancer early and Prostate-specific antigen (PSA) is a test to diagnose its extent. These should be included in routine examination after 50. Treatment options include radiation therapy, surgery, hormone therapy, and chemotherapy. Erectile dysfunction is common side effect of the treatment. It usually improves within two years. Good news about prostate cancer is that it usually grows slowly and 9 out of 10 cases are detected early and have good survival rate. Prostate cancer survivors who exercised regularly had lower risk of dying.

9 Things women want perfect in their body
Hair straightening do's and don'tsWhat's in a hair? Well when someone thought of this quote, he or she certainly did not foresee the future because in today's world hair is everything. For a woman and a caterpillar at least! Let's just talk about women! Hair not only covers your scalp, but also protects it.  Hair is known to be something that enhances the beauty of a woman, as there is nothing like the feel of smooth and silky hair caressing the shoulders. Women all over the world dream to have beautiful, strong, silky, and preferably, long straight hair. Why straight hair? Let's find out, women are born with all kinds of hair, curly, wavy, long, and short but according to some women there is nothing that beats having a straight hair and there are women in this world who could go to any length achieving that straight hair they always desired. One of those ways is straightening, a styling technique used since the 1980's, which involves the flattening as well as straightening of hair, to give it a smooth, streamlined, and a sleek look. Straightening can be of two types, temporary or permanent. Temporary straightening can be achieved by a straightening iron or relaxers and generally lasts up to the first wash. Permanent hair straightening generally requires the use of Lye and other chemicals (more commonly known as creamy crack) with the help of a hot comb, hot iron, and relaxers. Permanent straightening, with proper care, can easily last up to a year. According to documentary "Good Hair" by actor Chris Brown, African American women are known for their profound use of "creamy crack" to get that perfect straight hair they long for. They are also the women who make the cosmetic companies rich, thanks to their profound use of hair straightening and hair care related products. African American women also account for the highest amount of money spent on hair care and hair care related products. Coming in a close second are the women from Central and South East Asia. These women are also known to go to extremes to get that perfect straight hair look, which is generally shown in TV Commercials endorsed by celebrities. Now that we are aware of the statistics, it is time that we look into the do's and don'ts of hair straightening. Straightening your hair once in a while may sound like a good idea, but it is extremely essential that we understand that extreme care is required here. Hence it is always better to know the do's and don'ts before we decide to break the bank (straightening ain't cheap) for straightening treatments. Do's : Make sure your diets consist of plenty of healthy foods, water. Also doing regular exercise is advised. Always use a shampoo and conditioner that best suits you. Remember to ask your stylist about the kind of products that suit you. Always go for hair spa treatment once a month since your hair needs that extra nourishing. Don'ts : Do not wet your hair at least for three days after the treatment. Do not tuck your hair behind your ear. Avoid twisting your wet hair with a towel. Avoid extreme scrubbing of your hair while shampooing. Straightening even once can cause excessive damage, hence do not do it repeatedly. Straightening your hair once in a while is okay, but doing it continually is ill advised as it can have a lot of negative consequences. Straightening also comes with certain side effects such as heavy chemical reaction, dizziness, permanent hair damage, dryness, skin irritation, itchiness, and severe chemical burns. Hence, it's always better to have a professional do it at a salon rather than doing it yourself. Hair straightening, though done by the same method all around the world, requires different types of hair care products as the hair type is mostly related to your race and ethnicity and your geographical location.

10 tricks to motivate kids
8 Tips to calm the crying baby
Your bundle of joy comes with bundles of fascinating facts Blue-eyed wonder: Most babies are born blue-eyed. The melanin pigment that decides the color of the eyes is not developed at the time of birth. So the babies are born with blue/light eyes irrespective of the genetic makeup. By the time the baby is 6-7 months old, the pigments start developing and the baby's eye colour changes as per the genetic makeup of the parents. Marked for life: One in every three infant is born with a birthmark! No tears: That is true! New born babies do not shed any tears. The lacrimal duct and the tear glands are well developed but they produce just enough tears for lubrication. Actual tears start appearing after one month of age. Crawling wonders: New research has found that babies can crawl almost as soon as they are born. When left to themselves, they are quite capable of using their limbs and find their way to food i.e. the mother's breast.And we thought that they are tiny helpless creatures! Temperature sensitivity: Babies are much more sensitive to temperature changes and body heat.Though the baby can't throw off the clothes to cool down, it is smart enough to do other things. When the baby is cold, it will move around more and if it is too hot it may just lie still as if sunbathing. Touch therapy: Touch is the most highly developed sensation in babies, even in premature ones. The touch sensation develops from head to toe with the mouth being the most sensitive. No wonder they tend to put everything in their mouths. Short-sighted: Babies are short sighted at birth. Their vision is set to a limit of 8-to-12 inches. They can see people and objects clearly only if they are within this range. Brain size: The brain grows at such a rate in newborns that by the end of the first year,the brain is double the birth size and half its final size! Palmar Grasp: New born babies have a strong grip, as strong as a monkey's. The grip is so strong that if you dangle them on one hand, they can support their own weight. This probably originated from the primitive survival instinct. This strong grasp reduces after a couple of months. Taste buds: Babies have more than 10,000 taste buds situated all over the tongue and even at the roof and sides. As they grow, these extra taste buds disappear.
Obesity is not just an adult problemWith fast food chains multiplying in the country faster than you can say Maharaja Mac, there is an urgent need to monitor our diet. While most of the nutritional advice is directed at adults, kids too are exposed to the dangers of empty calories. Childhood obesity is on the rise across the world including India. How does obesity affect children? And what can parents do to ensure this doesn't happen? We will try to answer some of your questions. What are the causes of obesity in children? Lack of physical activity: Nowadays, children spend more time sitting at home - doing their homework, watching TV, and playing games on PC, console tablets or smartphones. Play time on the ground outside has shrunk. As a result, they don't get enough exercise. Unhealthy food choices: Our busy lifestyles leave us with little time to plan for or prepare every meal. The alternative is to go for quick-to-cook food like Maggi. Food ordered from outside too is invariably unhealthy. While having it once in  few days is not a problem, making it a way of life leads to problems. Overweight parents: The eating pattern and lifestyle of parents has a big influence on a child's health and weight. Obesity can be hereditary. Lifestyle and environment: When parents are unable to pay much attention on their children due to their busy schedules. As a result children rely more on ready-to-eat food or junk food. Genetic factors:  For some kids, genetic factors may be the reason behind obesity. A rare genetic disorder called as Prader-Willi syndrome causes severe weight gain in kids. What health problems can obesity cause among children? Type-2 diabetes Eating disorders like bulimia or binge eating (excessive eating or drinking) Problems with foot structure Liver problems Respiratory disorders - breathlessness during exercise Difficulty in breathing while sleeping causing snoring or poor sleep What can parents do to prevent or control obesity in children? Parents must make kids understand the ill-effects of eating junk food. They must limit their snacking on junk foods. Encourage the kids to participate in physical activities and outdoor games. Make exercising a routine for the children. Join them during exercising to make it a fun time for the family. Set an example for your kids by following a healthy diet and eating habits yourself. Limit TV time and playing videogames. Parents must include whole grains, fruits and vegetables in the diet of their children. Limit fats intake to not more than 25%-30% of total calories. Make sure to go through the nutritional label while purchasing any processed food.

Anxious about anxiety?Anxiety disorder is a term that almost everyone has heard and experienced in some form or the other. It is a generic term used to describe different forms of a mental disorder wherein those afflicted show typical characteristics of great apprehension, fear and trepidation. The symptoms, of course, vary depending on the severity of the affliction. So you can have 'anxious moments' when you narrowly escape an accident while driving - that's temporary and natural, while some others might have chronic anxiety which might need medical aid. Types of anxiety disorders Generalized anxiety disorder: There is no specific reason for the symptoms of anxiety i.e. restlessness, apprehension, worry, and panic. Thus the term general anxiety disorder (GAD) is any irrational worry which is disproportionate to the source of anxiety. GAD is a state of perpetual irrational and persistent fear which absorbs a person's time or can disrupt his normal functioning. The symptoms of GAD are light headedness, sweating, difficulty breathing, nausea, and numbness. Phobias: Phobias are an irrational morbid fear for certain things or objects. The list of phobias is exhausting as it is anything that a human being is capable of being afraid of. Thus you have arachnophobia which is the fear of spiders, homophobia, which is the fear of homosexual people orxenophobia,the fear of foreigners. Phobias can completely paralyze and terrorize a person and is a form of anxiety disorder. Obsessive compulsive disorder: This is the classic loop where a person is afraid of certain situations arising constantly and thus takes precautionary measures to ensure that it won't. Only thing is that this turns in to a compulsive ritual which can throw her in a loop. Thus a person can be said to have OCD if she persistently checks to see if the gas valve is off as she has a fear that she will set fire to her home. It is a particularly distressful anxiety disorder. Post-traumatic stress disorder: This is anxiety arising out of a traumatic incident which the person undergoes. It could be a horrific accident or an extremely brutal incident which the person has witnessed. The trauma is revisited again and again in the mind and manifests as anxiety. This disorder is based on real events that the person has experienced or undergone and can take a long time to heal. Panic disorder: This is characterized by panic attacks or episodes where great terror or discomfort is experienced. It is a very unsettling experience as the patient feels he is about to go unhinged or something dangerous or embarrassing is going to happen to him. Thus the sensation or feelings of panic build up and reach a crescendo resulting in a panic attack. Sometimes in a panic attack, the patient's reality and perceptions are distorted and blurred and can thus put him in danger. According to the National Institute of Mental Health there could be a number of reasons for anxiety disorders. They vary from early childhood environment to lifestyle causes, heredity and even environment.    
What is megalomania?Bertrand Russell's quote on megalomania perfectly describes the condition:"The megalomaniac differs from the narcissist by the fact that he wishes to be powerful rather than charming, and seeks to be feared rather than loved. To this type belong many lunatics and most of the great men of history." Megalomania is a delusional bipolar disorder. The sufferer believes he is an all-powerful person and that he is superior to all other people. Megalomania comes from the Greek words megalo which means large or great and mania which means madness. It is a psychopathological disorder that has delusional fantasies of power, exaggerated self esteem and a sense of omnipotence. The sufferer may believe he is God or some famous athlete. Although megalomania is a term used for power hungry people, it is clinically described under the mental disorder of narcissism. Narcissism is self-love. Though self-love is a healthy concept, narcissism is a pathological state where one loves oneself to the extent that he starts despising others. Megalomania is caused by certain phobias and mental conditions associated with emotions and personality. In everyday life, megalomania can be a person's mental way of reacting to frustration, abandonment or some serious loss. In the social world, the term megalomaniac is often synonymous with control freaks, power-drunk army generals, executives and politicians. The treatment of megalomania includes medications. The challenge here is that the person may not believe he has anything wrong with him. He, in fact, believes that he is so great that no harm can come to him, so talking him into getting himself treated is very difficult. Adolf Hitler, the German dictator, was a power-hungry control freak. He believed that he was the supreme commander and that his race was the only race suited to inhabit earth. All other races, especially Jews, were inferior and had to be wiped off the face of the earth. Adolf Hitler was megalomaniac.

5 tips to reduce your salt intakeSalt is an inevitable part of our food, but added salt has harmful effects on the body. The list of benefits in reducing sodium/salt intake in our diet runs long, ranging from lower blood pressure, in turn leading to reduced risks of heart disease, obesity, and diseases of the kidney. The daily sodium intake of an individual should not exceed 1500-2300 mg per day (a table spoon of salt approximately), and this needs to be maintained in the salt added to our food, including the processed food and drinks we buy. Sodium, an indispensable component of our diet, is consumed in excess by most of us. Follow the tips, as mentioned below, to curb your daily salt intake. Avoid added salt. Do not add salt to already cooked food while eating. Keep a diary and make a list of foods with salt in them that you eat daily. Do not forget to add pickles, spices, papads, salted biscuits, and salted nuts. All of these are highly loaded with salt. Next time you go shopping read the labels. Choose low-salt options-sauces, crackers, khakhra, instead of papad. Make an attempt to eat less canned and processed foods. Choose fresh fruits and vegetables over processed food. Eat less bread. Each bread slice has about 250 mg of sodium. Do not mistake bread to be healthy. Next time, keep this in mind when you go out to eat pizza. Pizza base is like bread. While cooking food, make it a point to add salt only towards the end in the recipe. This way you will need to add lesser salt. Sodium content of some foods Bread (one slice) - 250mg Cheese pizza: 450 - 1200mg Tomato soup: 350 - 1000mg Potato chips: 100 - 150mg

Winter - When your heart feels the cold too!As per a study in America, 193.6 people of every 10000 people die of a heart disease every year. 53% of the heart attacks occur in the winter months. Heart diseases have a seasonal trend as found by medical research recently. A team of medical researchers recently conducted a survey which saw 10,000 participants between the ages 35 to 80 from around seven European countries. The study was conducted to see if there is any seasonal variation in the presentation of heart diseases. The participants were measured on the parameters of blood pressure, waist circumference, body mass index, blood glucose levels and blood lipid levels. The parameters were later adjusted for sex, age and smoking. The results revealed that the incidence of heart disease shows an upward trend in the winter month [Jan to Feb] as compared to the summer months [June-Aug]. The researchers accept that there is no logical explanation to these findings. A plausible cause being the fact that the eating habits change in winter. One tends to eat more which in turn increases the cholesterol levels leading to heart diseases. Several other theories are being put forth. According to one, during the winter months the body undergoes hormonal imbalance. The day and night variation in the hormone levels, especially that of cortisol varies. This results in a lower threshold for heart attacks. Yet another theory says that the cold temperature tends to constrict the arteries narrowing the blood flow to the heart tissue and this result in a heart attack. On the basis of this study, scientists advise that more attention is to be paid to heart health during the winters.

Female circumcision - Health EffectsThe procedure is carried out by either snipping off a piece of the clitoris or removal of all external genitalia for non-medical reasons. The procedure is carried out outside hospitals and the environment may not be effectively clean and could lead to infection. The painful procedure causes a lot of fear and distress. Some countries have begun to use healthcare personnel to cut the genitals, which reduces pain, bleeding and infection but it does not mean that it is acceptable by the United Nations. Even though the United Nation has termed female circumcision as a violation of human rights, there are millions of girls suffer because it is a requirement for girls so that they remain pure. It is supposed to lower female libido so that they do not indulge in any kind of sexual activity before marriage. Immediate complicationsGirls are likely to suffer severe pain besides the fear that accompanies such a procedure. It can cause them more pain when they try to urinate. If there is severe bleeding, it can lead to haemorrhage. The tissues that form the genitals are severely damaged and healing may not take place immediately and sores can form leading to more pain. Girls can retain urine for fear of the pain. There is always a chance of contracting tetanus or other bacterial infections like sepsis which lead to formation of pus. Besides cutting, procedures can include pricking, piercing, incising, scraping, and cauterizing the genital area. Long term health problemsBesides the immediate problems, female circumcision can lead to long term effects including infertility. The girls can be subjected to urinary tract infections and bladder infections that can recur again and again. Sometimes cysts may also form. There are chances that there could be increased risk of problems during childbirth which could in extreme cases result in the death of the newborn baby. According to UN estimates more than 125 million girls and women are living with female circumcision. Women may be subjected to continuous surgeries especially in those cases where the vagina has been stitched to make it narrow as part of the circumcision process. Once the girls are married, the vagina is unstitched to have sexual intercourse. During childbirth, the vagina may need to be cut again to deliver the child and then stitched up again. This is a continuous problem and women should be spared from this pain and trauma.
Sex during PeriodsOpting to have sex is a choice that both partners have to make. On the brighter side, sex at the time of menses may help provide pain relief from cramps or painful menses as feel-good hormones are released during sex and orgasm. It may shorten period by a few days, even if the periods are normal, healthy, but the additional contractions of uterus during orgasm might help to shed your menstrual blood faster, thus finishing your period a bit sooner. However sex is off-limits during that time of the month for most of the women as being intimate feels unclean and messy and hence they might not feel comfortable doing it at the time. Tips for clean menstrual sex: Be prepared with a towel on the bed or under the pelvic area. A warm, wet, wash cloth will help freshen up with afterwards. Position properly. Woman lying on her back will bleed less. Use a cervical cap or diaphragm to protect you from pregnancy as well as lessening menstrual bleeding during sex by covering the cervix. Tips for safe menstrual sex: It should not be unprotected sex. You can still contract infection. This may not apply to monogamous couples who have been together for a long time in a committed relationship. Though uncommon, pregnancy is possible even during menstruation.
