‘Tweeting for hours is bad for health’
Washington: Don't spend hours tweeting, it's 'unhealthy' — that's the message from Twitter's boss.
Biz Stone, co-founder and creative director of Twitter, has told the popular micro-blogging site's 500 million users that spending hours tweeting is not healthy.He says he'd prefer that people visit the popular social networking site frequently than sacrifice their life to it.
Instead fans should use the site to find what they want — and they go and do something else, the Daily Telegraph online quoted Stone as saying. Users have complained that the 140-character messaging site is addictive, with some staying logged on for up to 12 hours at a time.
He said using Twitter that much was not what he had intended. "I like the kind of engagement where you go to the website and leave because you've found what you are looking for or something very interesting. PTI

Oranges and grapes cut the risk of stroke: Study
London: Want to reduce the risk of a stroke? Eat oranges and grapefruit daily, if possible, says astudy.
Researchers at Norwich Medical School in the University of East Anglia have found that oranges and grapefruit protect against a 'brain attack' due to anti-inflammatory properties, the Stroke journal reported.For their study, researchers analysed 69,622 women who were taking part in the ongoing Nurses' Health Study in US.
They investigated the strength of protection from flavonoids, a class of antioxidant compounds present in fruits, vegetables, dark chocolate and red wine.
The study used 14 years of follow-up data provided by 69,622 women who reported their fruit and vegetable intake every four years.
The team examined the relationship of the six main subclasses of flavonoids with risk of ischemic, hemorrhagic and total stroke.
Women who ate high amounts of flavanones in citrus had a 19% lower risk of blood clot-related (ischemic) stroke than women who consumed the least amounts, the Daily Mail reported. PTI

Rollercoaster weather takes health for a ride
The freak fluctuation in city temperatures over the past few days has led to more than just a spike in viral infections. Other than cough, cold and respiratory problems that are characteristic of a flip-flop weather, several Mumbaikars have also been seeking medical advice for loss of appetite, digestion troubles and overall lethargy.
City doctors told TOI on Thursday that they have been tending to complaints of low blood pressure, lack of focus and day-long drowsiness as well. They reason that these could be an outcome of metabolic imbalance, as body cells may not be able to cope with the extreme fluctuation of over 15 degrees Celsius in day and night temperatures. Doctors said that any gap in temperatures beyond 15 degrees can affect one's health and coping mechanism.Dr Hemant Thacker, who consults at Jaslok and Breach Candy hospitals, said, "The temperature clock exposes the internal cellular metabolism to this
fluctuation, which then cannot function normally." He said that by the time the cell adapts to the high temperature outside, it is already evening and cooler, and the cycle continues.
Dr Shahid Barmare, who consults in Kohinoor Hospital, seconded that after extreme heat during the day, the body is unable to adapt to a dip in temperature at night, and then, it's back to hot weather the next day. "Apart from an increase in respiratory worries, we are also seeing a high number gastrointestinal problems." Explaining the phenomenon, Barmare said even food tends to get stale faster in this weather. "Moreover, because humidity increases during the day (which causes people to sweat more), there are a few cases of dehydration too, especially among children and the elderly."
Besides, said Thacker, "special functions" such as thinking, eating, sleeping and digestion can get affected. "A person may suffer behavioural dysfunction... Moreover, the cells want water during the day because of the heat. But by night, the cells do not know what to do with the excess water they have collected during the day. Thus, the body passes more urine during the night and preserves water in the day. The kidneys too work overtime."
Dr Khusrav Bajan, intensivist at Hinduja Hospital, though, remained hopeful that Mumbaikars would weather the erratic temperatures. He said the current conditions are not as extreme and the body's thermal system is good enough to combat the fluctuation. "More viruses are thriving and thus there are more viral infections
—including respiratory
infections and conjunctivitis. The body needs good
hydration, regardless of the season. Since we feel hungry and eat more in winters, it does become a bit of a problem during the transition period between seasons—as it is now. Sweat glands get constricted at night, so there is no sweat and energy is conserved. That, however, is not the case during the day, which is why one may feel tired or lazy."
Doctors advised Mumbaikars to minimize exposure to extreme temperatures by not entering an air-conditioned room right after coming from outside heat. Avoid extreme body exertion and eat easily digestible food, they added.

Homeopathy treats hair loss safely and effectively
HEAL WITH HOMEOPATHY
Twenty-eight-year-old Biju (name changed), a postdoctoral research fellow, presented with hair loss. He reported that his hair loss on the scalp, which first appeared to be insignificant, was now worrying him no end. He thought that he would go bald quite early, like his father and uncle. Biju said he had lost 30-35 per cent of his scalp hair, during the past one year. It was apparent that his hectic work schedule and chaotic lifestyle were taking a toll. Add to this smoking and alcohol to 'beat' his stressful existence, and Biju's hair loss was only adding to his woes, affecting his selfesteem and work performance. He felt that he was falling behind in his boss' view — and, this would affect his appraisal.
When hair loss is not appropriately treated, it can progressively lead to baldness, or bald-headedness — not a pleasant feeling. It can also upset one's 'apple-cart' of self-esteem and self-belief and lead to psychological distress. Besides, hair loss can precede or co-exist with systemic disorders like high blood pressure, heart disease and diabetes, aside from thyroid or hormonal problems.We reviewed Biju's case and symptoms in detail and diagnosed his problem as Androgenetic Alopecia (AGA). AGA is a progressive disorder. It presents with receding hairline and balding over the scalp. After thoroughanalysis, we prescribed him the homeopathic Lycopodium — a remedy which we deduced matched Biju's temperament and presenting symptoms. We also advised him to change his frenzied lifestyle, get adequate sleep, quit smoking, avoid alcohol — smoking and alcohol 'activate' hair loss — and, include soy-rich food in his diet for good hair health. With regular followups, we recorded a noticeable improvement in Biju's hair loss. In a year's time, his hair loss responded favourably to homeopathic treatment, so also his sense of self-confidence.
Homeopathy treats the underlying cause, not just hair loss on the surface. If, for instance, hair loss stems from depression and emotional stress, it is best treated with the homeopathic remedy, Acid Phosphoricum, along with lifestyle changes. International research studies have demonstrated that homeopathic remedies are clinically effective in treating hair loss from the'root.' They stimulate hair follicles; they also strengthen hair, without side-effects.

Fasting once or twice a week could help you live longer
London: For many people, the key question regarding fasting is whether it's good or bad for health. Now, a new study says that skipping meals for a couple of days a week could help a person live longer.
Researchers at the National Institute on Ageing have found that fasting for one day or two days a week is key to a longlife because it can protect the brain against Alzheimer's, Parkinson's and other degenerative brain conditions. Chemical messengers in the brain are boosted when calorie intake is restricted, say the researchers.It has long been known that severely restricting calorie intake can increase the lifespan of rats and mice and it has been suggested there could be a similar effect in humans too but the theory is difficult to test.
Now, the researchers have found the positive effects of fasting, 'The Daily Telegraph' reported.
Prof Mark Mattson, head of the institute's laboratory of neurosciences, said: "Reducing your calorie intake could help your brain, but doing so by cutting your intake of food is not likely to be the best method of triggering this protection. It is likely to be better to go on intermittent bouts of fasting, in which you eat hardly anything at all, and then have periods when you eat as much as you want." PTI

A new blood test can reveal individual lifespan
Don't put expiry dates on people
We thought that medical science was about extending people's lifespans, rather than about telling them how long they have to live. Therefore a new medical test, which will be available in India from this year, seems of questionable value. A simple blood test like the one that estimates cholesterol, it will tell patients the rate at which they are ageing. Unless means can also be found for slowing down this rate, just coming to know how fast our biological clock is ticking – from the length of telomeres or protective chromosome caps in our cells – is hardly helpful. A person's longevity is determined by several factors, some of which can hardly be measured. Not knowing how long one lives is part of the glorious uncertainty of life. But the telomere test threatens to take all that away by putting an expiry date on each person. When scientism induces undue fatalism, it's time to discard it.Proponents will misleadingly argue that taking the test is a matter of individual choice. But imagine the Orwellian uses to which such a test can be put. The marketing of the test as a definitive gauge of one's health makes it susceptible to mischief and misuse. For instance, insurance providers could deny a customer their service based on her telomere test. An
employer could use the test as an excuse to fire an employee. In addition to their existing stringent criteria, matrimonial advertisements could demand the test for prospective brides and grooms.
But the biggest argument against the test is that it militates against hope. Hope is the ultimate embodiment of the human spirit. It can push people to conquer the impossible, allowing us to celebrate life rather than brood over its finiteness. In that sense, the telomere test focusses on the empty half of the glass, breeding a negative outlook on life.
Test is a boon to mankind Pyaralal Raghavan
Asimple blood test to measure lifespan and pace of ageing is yet another important gift that science has bestowed on humanity. Uncertainties about individual lifespan have been a
major worry that has plagued civilisations since ancient times. So much so that scientific study of lifespan has now even slowly evolved into a distinct branch of science called life extension science, with disciplines like experimental gerontology or biomedical gerontology. The ultimate goal in these disciplines is to discover how to slow down or even reverse the ageing process. But even short of that, there can be a lot of value in finding out how long one's lifespan extends.
The issue, after all, fascinated human beings for centuries before modern scientific methods took over. That's why soothsayers, fortune tellers, palm readers and so on had a field day speculating on it. To this day, probably the most popular question directed at fortune tellers has to do with the length of one's lifespan. If there's so much curiosity on the issue, a blood test can now tell all.
An accurate projection of lifespan will be a major breakthrough and a boon as it will empower people to take informed decisions on major matters of personal importance. These include career choices, marriage and size of families. One would not, for example, like to have children and then leave them orphaned at a young age. The test will help many to fulfil longcherished dreams, ensure smooth succession planning, help provide for retirement or dependents and also ensure safe transfer of wealth to inheritors. And, above all, it will also allow more motivated persons to even grab a second chance by attempting to prolong the estimated lifespan by making substantial changes in lifestyles or seeking other medical remedies.

‘HIGH-TECH TOYS’ GIVING ADULT INJURIES TO KIDS
Children as young as eight are suffering adult injuries such as repetitive strain injuries (RSI) and neck pains from using hand-held electronic devices, experts say. According to chiropractors, children using 'tech toys' such as touchphones and tablets and hand-held games are complaining of repetitive strain injuries of the thumbs, wrist and elbows, stiff necks, headaches and sore shoulders, which are injuries usually associated with adults working with computers. Chiropractors Association spokesman Dr Kerein Earney said children were risking permanent damage because of excessive game play. Dr Earney said she saw an eight-year-old with an opposite neck curve from playing hand-held games. She also saw a 15-year-old boy who spent the whole school holidays watching TV and playing computer games in his room and began experiencing muscle aches and migraines. "When children play these games, or use these tech toys, they are often slouched in a chair, head down and they're putting a lot of pressure on their head," the Herald Sun quoted Dr Earney as saying. "They're like that for quite significant periods of time. It's only going to get worse unless they do something about it. It will end up being costly and will lead to long-term health problems," she added. IANS

Teach children to enjoy eating vegetables and fruit with positive persistence
This article is part of a series by the Ismaili Nutrition Centre that examines evidence-based studies published in scientific journals, and distills what they mean to our readers.

Few children are born with a liking for every vegetable, but researchers in France and Switzerland wanted to know if infants could learn to enjoy a specific vegetable, and how many tastes it would take. They published their results in the Journal of Food Quality and Preference in April 2007.
The researchers found 49 mothers who had stopped offering a vegetable because their child refused it. The mothers were asked to give the disliked vegetable and a well-liked one (ex. carrot puree) on alternate days, so that the infant would eat the disliked vegetable only once every two days.
Initially, the infants only ate 39 grams of the disliked vegetable compared to 164 grams of the liked food, but this changed very quickly. By the eighth exposure, infants were eating 174 grams of the initially disliked vegetable! The effects were long-lasting, with two out of three infants still eating the initially disliked vegetable nine months later.
A more recent Belgian study published in the journal Appetite in December 2010, looked at 755 families to see the effects of parenting styles (laxness, over-reactivity, etc.) and children's personalities (shyness, stubbornness, etc.) on fruit and vegetable eating habits. Although no parenting style or child personality trait was seen to make a big difference, the study made two important observations: first, parents who ate more fruits and vegetables had kids who ate more fruits and vegetables. Second, kids ate more fruits and vegetables when parents tended to use child-centered techniques such as reasoning, offering choices, and praising, rather than parent-centered techniques such as warning or physical struggling.
What this means for you
Children, like adults, should be eating at least five servings of vegetables and fruits daily. When it comes to infants or toddlers, it may take more than 10 attempts to get the child to try something new, so don't give up as it takes time to get used to flavours, textures and consistency of food.
It's okay if your child refuses to eat one or two items, but parents have to just let it go and focus on encouraging kids to try new flavours and increase the variety of vegetables and fruits eaten in the home. Each meal should have at least 1-2 fruits or veggies.
Start with sliced fruit with cereal in the morning, coloured pepper strips in their lunch or sweet potatoes at dinner and frozen berries or sliced mangos as a dessert. Get kids involved in the kitchen and at the grocery store, and soon they will be more excited about trying more vegetables and fruits, just like their parents.
