If you’re looking for a fairly painless way to lose weight, researchers at Brigham Young University have a new solution for you: Put yourself on a regular sleep schedule. People who keep a regular sleep routine have a lower body fat than those who keep irregular sleep hours, says a new study.
Led by Bruce Bailey, professor of exercise science, researchers followed 300 female college students aged 19 to 26, who were given activity trackers（跟踪器）to watch their movements and activities, including waking and sleeping times . Researchers also measured their body composition (成分)before and after the one-week study period.
What the researchers found:
Body fat varied with sleep quantity. Women who slept between 8 and 8.5 hours a night had the lowest body fat. While those who slept less than 7 hours or over 9 hours had higher body fat.
High quality sleep was associated with lower body fat while poor sleep was connected with higher body fat.
Waking and going to sleep at the same time every day was most strongly linked with lower body fat.
The difference in body weight was greater with more variation（变化）in sleep pattern. Women whose sleep patterns varied by 90 minutes a night had higher body fat than those whose sleep patterns varied by 60 minutes or less on average.
The study followed up on a body of research conducted over the last few years that ties quality and quantity of sleep to weight loss and better weight control. While researchers don’t know exactly how sleep schedules affect body weight and fat, other studies have shown that sleep has an effect on physical activity, appetite（胃口）, and the hormones（荷尔蒙）that control metabolism（新陈代谢）, and the signals that tell us we’re full.

When I was small and my grandmother died, I couldn’t understand why I had no tears. But that night when my dad tried to cheer me up, my laugh turned into crying.
So it came as no surprise to learn that researchers believe crying and laughing come from the same part of the brain. Just as laughing has many health advantages, scientists are discovering that so, too, does crying.
Whatever it takes for us to reduce pressure is important to our emotional (情感的) health, and a study found that 85 percent of women and 73 percent of men report feeling better after crying.
Besides, tears attract help from other people. Researchers agree that when we cry, people around us become kinder and friendly and they are more ready to provide support and comfort. Tears also enable us to understand our emotions better; sometimes we don't even know we' re very sad until we cry. We learn about our emotions through crying, and then we can deal with them.
Just as crying can be healthy, not crying — holding back tears of anger, pain or suffering — can be bad for physical (身体的) health, Studies have shown that too much control of emotions can lead to high blood pressure, heart problems and some other illnesses. If you have a health problem, doctors will certainly not ask you to cry. But when you feel like crying, don't fight it. It's a natural — and healthy — emotional response (反应).
