Sticking to your body's natural sleep-wake cycle is one of the most important strategies for achieving good sleep. If you keep a regular sleep schedule, you will feel much more refreshed and energized than if you sleep the same number of hours at different times. This holds true even if you change your sleep schedule by only an hour or two. Try the following ways to help you stick to your body clock, and you will have a better sleep.
Keeping a regular sleep-wake schedule helps set your body's internal clock and improve the quality of your sleep. Start by setting realistic bedtime that will work with your lifestyle. If you're getting enough sleep, you should wake up naturally without an alarm. If you need an alarm clock to wake up on time, you may need to set earlier bedtime.
Avoid sleeping in — even on weekends or nights you've stayed up late. If you need to make up for late night, choose a daytime nap rather than sleeping in. This way allows you to pay off your sleep debt with disturbing your natural sleep-wake rhythm.
Be smart about napping. As mentioned above, napping is a good way to recharge and make up for lost sleep hours. But if you tend to have trouble falling asleep or staying asleep throughout the night, napping can make things worse. Besides, limiting them to 15 to 20 minutes in the early afternoon is a good idea.
A. Never sleep after dinner.
B. Consistency is vitally important.
C. Try to go to sleep and get up at the same time every day.
D. Don't turn to sleeping pills every time you can't sleep quickly.
E. If sleeplessness is a problem for you，consider ridding naps altogether.
F. Choose a time when you normally feel tired, so that you will fall fast asleep.
G. The more your weekend / weekday sleep schedules differ, the worse the jet lag-like symptoms you will experience.
The book ABigFatCrisis: TheHiddenForcesBehindObesityEpidemic— andHowWeCanEndIt by Deborah Cohen, a senior natural scientist, is very popular now. {#blank#}1{#/blank#} But according to this book, the following are some misunderstandings of obesity or being overweight.
1)．If you're obese, blame your genes.
{#blank#}2{#/blank#} Yet, between 1980 and 2000, the number of Americans who are obese has doubled—too quickly for genetic factors to be responsible. At restaurants, a dollar puts more calories on our plates than ever before, because restaurant meals usually have more calories than what we prepare at home, so people who eat out more frequently have higher rates of obesity than those who eat out less.
2)．If you're obese, you lack selfcontrol.
Research shows that if we are faced with too much information, we have a tendency to make poor choices on diet. {#blank#}3{#/blank#} Even, the most vigilant(警觉的)people may not be good controllers of themselves.
3)．{#blank#}4{#/blank#}
Although the US Department of Agriculture estimates that fewer than 5 per cent of Americans live in the “food deserts”， about 65 per cent of the nation's population is obese. For most of us, obesity is not related to access to more fresh fruits and vegetables, but to the choices we make in supermarkets.
4)．The problem is not that we eat too much, but that we don't exercise.
Michelle Obama's “Let's Move” campaign is based on the idea that if kids exercise more, childhood obesity rates will decrease. {#blank#}5{#/blank#} In fact, although a drop in workrelated physical activity may explain up to 100 fewer calories burned, leisure physical activity appears to have increased.
A．Lack of access to fresh fruits and vegetables is a cause of obesity. B．Obesity rates have increased. C．Fresh fruits and vegetables we choose in a supermarket are related to obesity. D．But there was no obvious decrease in physical activity levels as obesity rates climbed in the 1980s and 1990s. E．People hold different views on obesity. F．People benefit a lot from physical activities. G．Our world has become so rich in food that we can be led to consume too much in ways we can't understand. |
