It's safe, it's simple, and it works: Drinking right amounts of water really can help you lose weight, new research shows.
In what researchers claim is the first-ever trial of the effect of water consumption on weight loss, scientists from Virginia Tech found that dieters who started each meal with two glasses of water lost nearly five pounds more, on average, than dieters who did not, over the course of 12 weeks. There's no shortage of clear evidence about how water might work to control your appetite (食欲). It ________________ so you don't eat so much; it keeps down your thirst so that you don't turn to calorie－rich sodas or juices. But until now, the researchers say, there has been no true evidence that water's appetite-controlling benefits ever translate into actual weight loss. Now there is. In the 12-week study period, dieters instructed to drink water with every meal lost an average of 15.5 pounds; dieters given no instructions lost, on average, just 11 pounds.
Perhaps the most surprising thing about the finding is how little we still know about healthy water consumption in general. In fact, although doctors and public health authorities regularly remind us to drink more water, very few studies give any insight into what our ideal quantity may be.
The new results today suggest that many people could indeed stand to drink a little more water than they do. But if you're looking to lose weight, be aware that it is actually possible to drink too much water, and you probably won't help matters any by drinking too much water at a time. In extreme cases, it can even be deadly. A couple of glasses with each meal, however, should be no problem at all for a healthy person.

Naturally regulate your sleep-wake cycle
Melatonin(褪黑激素) is a naturally occurring hormone(激素) that helps regulate your sleep-wake cycle. Melatonin production is controlled by light exposure. Your brain should produce more in the evening, when it's dark, to make you sleepy, and less during the day when it's light and you want to stay awake. However, many aspects of modern life can disturb your body's natural production of melatonin and your sleep-wake cycle.
Spending long days in an office away from natural light, for example, can impact your daytime wakefulness and make your brain sleepy. Then bright lights at night—especially from hours spent in front of the TV or computer screen—can hold back your body's production of melatonin and make it harder to sleep, However, there are ways for you to naturally regulate your sleep-wake cycle, improve your body's production of melatonin, and keep your brain on a
healthy schedule.
Increase light exposure during the day
☆Remove your sunglasses in the morning and let light onto your face.
☆Spend more time outside during daylight. Try to take your work breaks outside in sun light, exercise outside, or walk your dog during the day instead of at night.
☆Let as much light into your home/workspace as possible. Keep curtains and blinds open during the day, move your desk closer to the window.
☆If necessary, use a light treatment box. A light treatment box can create sunshine and can be especially useful during short winter days when there's limited daylight.
Improve melatonin production at night
☆Turn off your television and computer. Many people use the television to fall asleep or relax at the end of the day. Not only does the light hold back melatonin production, but television can actually excite the mind, rather than relaxing it. Try listening to music or audio books, or practicing relaxation exercises. If your favorite TV show is on late at night, record it for viewing earlier in the day.
☆Don't read from a backlit device at night (such as an iPad). If you use a portable electronic device to read, use an eReader that is not backlit, i. e. one that requires an additional light source such as a bedside lamp.
☆Change your light bulbs. Avoid bright lights before bed, use low-wattage bulbs instead.
☆When it's time to sleep, make sure the room is dark. The darker it is, the better you'll sleep. Cover electrical displays, use heavy curtains or shades to block light from windows, or try an eye mask to cover your eyes.
☆ Use a flashlight to go to the bathroom at night. As long as it's safe to do so, keep the light to a minimum so it will be easier to go back to sleep.
