10 ‘bad’ habits that are good for you

'Bad' habit that's good for you 1: Gossiping

 Most of us love a good gossip, whether we’re giggling over a colleague’s new romance or passing an opinion on someone’s outfit choice or behavior, and the good news is that gossiping could actually be good for us. Not only does listening to gossip help us to learn more about the characters of those around us, bonding and having a laugh with your peers also releases feel-good hormones which help to relieve stress and anxiety.

'Bad' habit that's good for you 2: Drinking coffee


 Although drinking too much coffee can be detrimental to your health, in smaller quantities the popular hot drink can actually be good for you. When drunk in moderation (no more than three cups per day), caffeine can speed up your metabolism, boost exercise endurance and reduce your risk of gallstones and kidney stones. A study by the Harvard Medical School has also found that women who drink two or more cups of coffee a day are less likely to be depressed, while separate research has shown that drinking three cups cuts risk of age-related diabetes.



'Bad' habit that's good for you 3: Fidgeting

It’s the bane of school teachers everywhere, yet research suggests that fidgeting may be no bad thing – at least in us adults. Research suggests that fidgeting can burn up to 350 extra calories a day, helping you to keep off those excess pounds. To further increase your calorie burn, try to squeeze in more incidental exercise, such as getting up to change the channel rather than using the remote control.

'Bad' habit that's good for you 4: Swearing

Swearing: it’s not big and it’s not clever... but studies suggest that in certain situations it may actually be good for you. According to a study by the University of East Anglia, swearing at work could help employees cope with stress and maintain solidarity. Meanwhile, researchers at Keele University’s School of Psychology found that swearing can provide effective short-term relief from pain. However, the study also notes that swearing should be reserved for crises only, as the higher the daily swearing frequency was for participants, the less pain relief they experienced.

'Bad' habit that's good for you 5: Skipping a shower

OK, so repeatedly missing showers may not win you any friends, but if you are ever tempted to skip a shower here and there, research suggests that you could be doing your health (and the environment) a favour. Daily washing not only strips your skin of the natural oils that keep it hydrated and supple, it could also strip your skin of good bacteria that help to prevent disease. If you do decide to skip a shower, just try to do it on a day when you won’t be vigorously working out!

'Bad' habit that's good for you 6: Losing your temper 

Many of us have been brought up to believe that losing our temper is the ultimate social faux pas. To an extent this is true (nobody wants to hang out with that person who is always losing their cool and shouting their mouth off), however research has found that losing your temper could actually be good for your health. Venting your emotions is believed to reduce the effects of stress, while a Swedish study found that men who bottled up their anger when unfairly treated at work doubled their risk of having a heart attack.

'Bad' habit that's good for you 7: Sunbathing 

In recent years, official advice has been that we should cover up in the sun at all times to protect ourselves from skin cancer. However, more recently experts have stated that actually little and frequent sun exposure is good for us. In the UK, where vitamin D deficiency is common, seven leading health groups and charities have issued a statement advising everyone to spend 10 minutes in the midday sun without sunblock in order to avoid rickets. Meanwhile, a US study has stated that the vitamin D produced by the sun could help ward off colds and flu. However, experts have stressed that people should cover up after 10 minutes, and skin should never be red at the end of the day.

'Bad' habit that's good for you 8: Having a lie-in 

Feeling guilty about your weekend lie-in? Don’t be! Research has found that sleep can help you live longer, boost your memory and reduce stress, while not getting enough can lead to accidents, weight gain, and increased risk of heart disease. Furthermore, delaying your morning workout in favour of some shut-eye may have health benefits, as research from Brunel University found that heavy training sessions early in the morning can compromise the immune system.

'Bad' habit that's good for you 9: Giving in to your cravings

Although constantly giving into junk food cravings is a sure-fire way to sabotage your healthy eating success, allowing yourself the odd treat will not only boost your happiness, it will also help you keep motivated to stay on track. Also, as many people crave the foods that they most attempt to
resist, allowing yourself a little of what you fancy can actually help to reduce cravings. If you have imposed extreme restrictions on your diet and cut out entire food groups, cravings could also be a sign of a nutrient deficiency in your diet.

'Bad' habit that's good for you 10: Daydreaming 

Many of us view daydreaming as a sign of laziness or form of procrastination; however, researchers at the University of British Columbia have found that letting your mind wander can actually help boost your problem-solving abilities. The study found that when participants minds wandered, the parts of their brain associated with problem-solving became more active than when focused on routine tasks. So, while daydreaming can increase the time it takes to complete your present task, it can allow you to unconsciously sort through other important problems in your life.

NASA Envisions Alien Worlds

For decades, NASA has delighted stargazers with pictures taken by astronauts, telescopes, and rovers across the galaxy -- photographic glimpses of real planets, moons, stars, and other heavenly bodies. When illustrators, meanwhile, stretch their imaginations -- giving shape and color to what, say, a sunrise on another world -- their work offers brilliant notions of what vistas beyond our tiny corner of space might look like. Captured by a camera or, as in this gallery, envisioned by artists, the far reaches of space continue to humble and amaze.  

Out of the Dust, a Planet is Born

In this artist's conception, a possible newfound planet spins through a clearing, detected around the star CoKu Tau 4 by the Spitzer Space Telescope, in a nearby star's dusty, planet-forming disc. The possible planet is theorized to be at least as massive as Jupiter, and may have a similar appearance to what the giant planets in our own solar system looked like billions of years ago.

12 Indian foods that cut fat

You don't have to acquire a taste for olive oil, seaweed or soya to maintain a low-fat, healthy diet. Indian cuisine can be healthy too, if it's cooked with oil and ingredients that take care of your heart and health. Ayurveda suggests you include all tastes - sweet, sour, salty, pungent, bitter and astringent - in at least one meal each day, to help balance unnatural cravings. Here are 12 foods that can help you lose weight and gain health:  

Turmeric : Curcumin, the active component of turmeric, is an object of research owing to its properties that suggest they may help to turn off certain genes that cause
scarring and enlargement of the heart. Regular intake may help reduce low-density lipoprotein (LDL) or bad cholesterol and high blood pressure, increase blood circulation and prevent blood clotting, helping to prevent heart attack. 
 
Cardamom : This is a thermogenic herb that increases metabolism and helps burn body fat. Cardamom is considered one of the best digestive aids and is believed to soothe the digestive system and help the body process other foods more efficiently.  

Chillies : Foods containing chillies are said to be as foods that burn fat. Chillies contain capsaicin that helps in increasing the metabolism. Capsaicin is a thermogenic food, so it causes the body to burn calories for 20 minutes after you eat the chillies.  

Curry leaves : Incorporating curry leaves into your daily diet can help you lose weight. These leaves flush out fat and toxins, reducing fat deposits that are stored in the body, as well as reducing bad cholesterol levels. If you are overweight, incorporate eight to 10 curry leaves into your diet daily. Chop them finely and mix them into a drink, or sprinkle them over a meal. Garlic : An effective fat-burning food, garlic contains the sulphur compound allicin which has anti-bacterial effects and helps reduce cholesterol and unhealthy fats.  

Mustard oil : This has low saturated fat compared to other cooking oils. It has fatty acid, oleic acid, erucic acid and linoleic acid. It contains antioxidants, essential vitamins and reduces cholesterol, which is good for the heart.  

Cabbage : Raw or cooked cabbage inhibits the conversion of sugar and other carbohydrates into fat. Hence, it is of great value in weight reduction.  

Moong dal : The bean sprouts are rich in Vitamin A, B, C and E and many minerals, such as calcium, iron and potassium. It is recommended as a food replacement in many slimming programmes, as it has a very low fat content. It is a rich source of protein and fibre, which helps lower blood cholesterol level. The high fibre content yields complex carbohydrates, which aid digestion, are effective in stabilising blood sugar and prevent its rapid rise after meal consumption.  

Honey : It is a home remedy for obesity. It mobilises the extra fat deposits in the body allowing it to be utilised as energy for normal functions. One should start with about 10 grams or a tablespoon, taken with hot water early in the morning.  

Buttermilk : It is the somewhat sour, residual fluid that is left after butter is churned. The probiotic food contains just 2.2 grams of fat and about 99 calories, as compared to whole milk that contains 8.9 grams fat and 157 calories. Regular intake provides the body with all essential nutrients and does not add fats and calories to the body. It is thus helpful in weight loss.  

Millets : Fibre-rich foods such as millets - jowar, bajra, ragi, etc - absorb cholesterol and help increase the secretion of the bile that emulsifies fats. Cinnamon and cloves: Used extensively in Indian cooking, the spices have been found to improve the function of insulin and to lower glucose, total cholesterol, LDL and triglycerides in people with type 2 diabetes.

Kepler 22b, new planet or super Earth

scientists have discovered Kepler 22b, a new planet or super earth. But do we have means to ascertain or make a definite claim about it asks M Sundaram?

NASA’s new finding, Kepler 22b has made people sit up and take notice. This is a planet that NASA says may support the life and vegetation. Though it may take decades or centuries in making things more clear about Kepler 22b as many analysts have said that saying something definite about
some planet as far away as 600 light years away is well nigh impossible, people are overjoyed with the finding.

For many of us, the distance of 600 light years may be very difficult to comprehend. One light year away if measured in our kilometer term is at least 10 trillion kilometers away from our earth. So you can ‘easily’ calculate as to how many years it may take to actually take you to that super planet that NASA scientists are talking about.

A reader has sent this sarcastic response, “Interesting discovery! What did it cost the American taxpayer for NASA to make this discovery? What do they really expect to learn from their telescopic observations? Think about this: The planet is 600 light years away (folks, that is 3,526,800,000,000,000 miles); it is reported that it would take 20 million years to reach the planet, which would indicate a required sustained average of 22,315 mph to get there. Sorry, but the whole space exploration operation begs the question: What have we really learned that will benefit us, and ad what cost?

But most of the people seem very happy to know that the planet looks like earth and may be the first planet to support vegetation.

With the new finding, NASA may silence many a voices that were seeking further slashing of its funding. Kepler mission has reportedly discovered as many as more than 1200 planets, but this is the first one that it claims may support vegetation. Kepler Mission or NASA Discovery mission number 10, is specifically designed to survey our region of the Milky Way galaxy to discover hundreds of Earth-size and smaller planets in or near the habitable zone and determine the fraction of the hundreds of billions of stars in our galaxy that might have such planets.

Kepler has been very intricately designed to detect stars millions of kilometers away. When a planet crosses in front of its star as viewed by an observer, the event is called a transit. Transits by terrestrial planets produce a small change in a star’s brightness of about 1/10,000 (100 parts per million, ppm), lasting for 2 to 16 hours. This change must be absolutely periodic if it is caused by a planet. In addition, all transits produced by the same planet must be of the same change in brightness and last the same amount of time, thus providing a highly repeatable signal and robust detection method.

A NASA report says, “Once detected, the planet’s orbital size can be calculated from the period (how long it takes the planet to orbit once around the star) and the mass of the star using Kepler’s Third Law of planetary motion. The size of the planet is found from the depth of the transit (how much the brightness of the star drops) and the size of the star”.

But it is clear that most of the findings of such missions are speculative and there is a whole lot of assumptions playing into it. So don’t be very ecstatic. It is just an assumption that there is some planet that may support human life. We are sooooooooo far away from having right technology to find anything worthwhile about it.
