Get proper sleep if you want to cut down on risk of dementia

Published

on

Having good sleep is linked to lesser risks of developing dementia and premature death, a recent study has suggested.
The study was conducted on Japanese adults who were above the age of 60. Out of 1,517 adults ,who were studied for 10 years, 294 developed dementia and 282 died. Those who slept less were found to have more chances of developing dementia and dying, however, those who slept less but had a high level of physical activity did not have a higher risk of dementia and death.
“Given the beneficial effects of physical activity on risk of sleep disturbance, these findings indicate that not only maintenance of appropriate sleep duration, but also modification of lifestyle behaviours related to sleep may be an effective strategy for preventing dementia and premature death in elderly adults,” wrote the authors.
The findings were published in the Journal of the American Geriatrics Society.
Another study which had appeared in the journal Neurology, determined that a good night’s sleep is essential for avoiding dementia. The team studied 321 participants who were above the age of 60. The study also found that the sleep should have the least amount of disturbance.
Spending less time in REM (rapid eye movement) sleep – which is when most of our dreams take place – and taking a longer time to enter REM sleep can lead to a higher risk of dementia.

Dermatologist Suggests Ways To Prevent Hair Damage In Monsoon

Published

on

With monsoons comes a breather from the sultry hot summer, a unique liveliness in the aura which is certainly a favourite of many. We all love petrichor and the very calmness which is attached to monsoons. But what we really don’t like about monsoons is the unpleasant humidity and hair damage. Not only does excessive humidity make us sweat, it also causes unavoidable hair damage which is quite difficult to deal with. Hair gets extremely frizzy because of humidity in the air and at times, no shampoos or popular home remedies for damaged hair actually work.
Dermatologist Dr Kiran Lohia explains that during monsoon, hair gets frizzy because there is a lot more moisture in the air. “Your hair picks up the moisture in the air and gets fluffed up. This is why hair gets frizzy. And to prevent hair from getting frizzy, it is important to provide enough moisture to your hair. The more moisture that there is in your hair, the less it will take from the air. You can apply conditioning serums or conditioners can prevent hair from getting frizzy during monsoon,” she says.
She goes on to add that you can even add your own conditioner on dry hair and apply on dry hair. “If you don’t have conditioners on you, you can even put body lotion on your hair. I personally have put body lotion on my hair to prevent hair from getting frizzy during monsoon,” says Dr Kiran.
Here are some more tips to prevent hair damage during monsoons:
1. Shampoo twice a week
In order to remove residue on your scalp because of rain water, use a mild and deep cleaning shampoo twice a week. Using a nice shampoo goes a long way when it terms of nourishing your tresses and preventing fungal and bacterial infections. Also, apply the shampoo with the right technique, which is applying it from root to tip.
2. Condition the right way
Conditioning hair with the right technique is as important as shampooing hair with the right technique. Make sure you apply conditioner only in the ends and lengths of hair. Also, avoid using too much hair conditioner.
3. Do not tie your hair tightly
When you tie your hair tightly during monsoons, it results in accumulation of rain water in your hair. This makes hair more frizzy and limp. During monsoons, make sure you tie your hair in lose ponytails and buns only.
4. Take regular oil massages
A good oil massage on your hair will help in reversing hair damage caused by monsoons. Hair oil massage gives a natural boost to moisture in your hair and revitalises the dry hair strands. It is also an effective and popular deep conditioning technique for hair. However, avoid using excessive hair oil as it will result in nothing but use of excessive shampoo, which is again harmful for your hair.
5. Use the right comb
During monsoons, it is the best to use a wide tooth comb. It helps in easy detangling of tresses and serves as a good conditioning comb.
6. Flaunt short hair
Monsoon is the best time cut your hair short. It reduces the hassle of maintaining them during monsoons.
7. Eat right
Healthy hair is a sign of good health. Good health is achieved by eating healthy and nutritious foods. If you aspire to strengthen your hair follicles, add more protein and iron rich foods in your diet. Foods rich in omega-3 fatty acids, such as salmon, mackerel, walnuts and curd are also good for hair health.

People with wrinkled eyes appear more sincere

Published

on

Do you use anti-ageing creams? Besides hiding your wrinkles, they may also negatively impact people’s perception of your sincerity, say researchers. The findings showed that human brains are pre-wired to perceive wrinkles around the eyes as conveying more intense and more sincere emotions. This eye-wrinkle feature, called the Duchenne marker, occurs across multiple facial expressions, including smiles, expressions associated with pain, and expressions of sadness. When participants were shown images of faces grinning and frowning with and without eye wrinkles, the participants focused on which one their brain deemed most important.
They systematically ranked the Duchenne smiles and Duchenne sad expressions as more sincere and more intense than the non-Duchenne expressions, the researchers said. “The expressions involving the Duchenne marker were always dominant,” said Julio Martinez-Trujillo, Professor at Western University in Ontario, Canada.
“So if the emotion is more intense, your brain actually prefers to bring it into perceptual awareness for longer time.” The results, published in the journal Emotion, are a step toward understanding the more general questions of why facial expressions contain the specific facial actions they do, and how that contributes to our understanding of emotion, the researchers said.
“These findings provide evidence of a potential universal language for reading emotions. In other words, a given facial action may have a single role across multiple facial expressions — especially if that facial action shapes your social interactions,” said Nour Malek from the university. “My interest now is, what will be the results if we do this same test with people with autism spectrum disorder. “They often have trouble reading out emotions from other people, so we wonder if that might have to do with their ability to read this marker for sincerity,” he said.
