Period of adjustment of biological rhythm after moving from one time zone to another, experienced as fatigue and lowered efficiency. It reflects a delay in the synchronization of changes in the level of blood cortisol, the major steroid produced by the adrenal cortex increase your risk of diabetes and weight gain.

New research suggests frequent night shifts and jet lag increase your risk of diabetes and weight gain.
Can working in shifts and constant jet lag increase your risk of obesity and diabetes? Yes, according to a new survey. 21 men and women volunteered for a Harvard Medical School Harvard Medical School (HMS) is one of the graduate schools of Harvard University. It is a prestigious American medical school located in the Longwood Medical Area of the Mission Hill neighborhood of Boston, Massachusetts. study which controlled how and when they slept, ate and exercised for five weeks.
Participants first started with 10 hours of sleep each day, which was then gradually reduced. Over time, they were also asked to sleep and wake up later to mimic change in time zones. Eventually, the participants were sleeping during the day and awake at night. Researchers had effectively simulated both working in shifts and frequent time zone changes.
Tests confirmed the worrying hypothesis. Over the five weeks, participants' metabolic rates fell 8%. Over a year, this metabolic slowdown could mean a four kilo weight gain if diet and exercise habits remain the same. There was another fallout. The reversed sleep cycle (sleeping during the day) and reduced sleep time also hit insulin levels. After three weeks, participants produced about a third less insulin in response to meals. Bloodglucose levels rose sufficiently to lable the participants' pre-diabetic.

Are you considering taking supplements? Here's a checklist to do so safely.
First, watch for extravagant claims. If it sounds too good to be true, it probably is.
Remember, most celebrity testimonials are paid for. The endorser may only be making claims for the pay-check.
While a little is good, more is not always better. In fact, having too much of some vitamins and minerals can also result in diseases or side-effects.
Finally, don't fall for terms such as "all-natural", "antioxidantrich", "clinically proven" or "antiageing".
Check scientific data of these products to verify their claims.

ARE E-BOOKS BAD FOR YOUR MEMORY?
A study at the University of Leicester History
The University was founded as Leicestershire and Rutland College in 1918. The site for the University was donated by a local textile manufacturer, Thomas Fielding Johnson, in order to create a living memorial for those who lost their lives in World War I. in England has found that good ol' paperbacks may hold a small edge over e-books when it comes to learning. Researchers found e-book users required more repetitive reading of the same text and more testing to imbibe what was on 'page'. The reason is something scientists call 'method of loci'. For example, remembering the location on a page where a particular anecdote or data point was mentioned helps in remembering the fact itself. E-books, such as the early Kindle A portable e-book device from Amazon.com that provides wireless connectivity to Amazon for e-book downloads as well as Wikipedia and search engines. Using Sprint's EV-DO cellphone network, dubbed WhisperNet, wireless access is free. It also includes a built-in dictionary. , for example, simply scrolled through text and only showed the percentage already read. The page itself was endless. Printed books instead, give physical reference points -the page number or position on a page. "Human short-term memory is extremely volatile and weak," says one of the scientists.
"That's why there's a huge benefit from being able to glance [across a page or two] and see [everything] simultaneously.
Exercise can help fight Parkinsons
Here's another incentive to exercise regularly. Recent studies have found that regular physical activity can aid in the fight against dreaded Parkinson's disease Parkinson's disease or Parkinsonism, degenerative brain disorder first described by the English surgeon James Parkinson in 1817. When there is no known cause, the disease usually appears after age 40 and is referred to as Parkinson's disease. . Specifically, scientists identified two benefits.
One benefit helped reduced the risk of the disease, while the other benefit helped sufferers live a more normal life for longer periods.
First, physical activity-particularly in early stages-helps build strength, balance and endurance.
These help patients later on when the disease takes reaches particularly debilitating stages. Scientists also found that patients who were in good shape scored better on thinking and muscle control tests and had a higher chance at a longer life. Finally, they found that vigorous exercise vigorous exercise A form of exercise that is intense enough to cause sweating and/or heavy breathing/ and/or ↑ heart rate to near maximum; VE is formally defined as that which requires > 6 METs; there is a graded inverse relationship between total physical has a "protective effect" on brain tissue.
