Beyond its influence on health, not getting enough sleep can lead to car accidents or other mistakes. Here are what sleep researchers have found about sleep.

How much sleep do we actually need?

It is known that all of us naturally need no less than eight hours of sleep per night. When we sleep below six hours per 24. We’re at an increased (增加的) risk of health problems. Some of us think we can make up any of those hours lost during the week on the weekends. Sadly there is no storage system (存储系统) for sleep in the brain.

Can we drink coffee instead of sleeping?

Coffee can keep us awake. Remember, too much coffee may throw off our sleep and energy cycles. So limit coffee and avoid caffeine for four to six hours before bedtime.

Does a sense of purpose connect to sleep quality?

A new research suggests a kind of strong connection between purpose in life and sleep. People who have a greater sense of purpose usually have better physical and mental health, which in turn explains their higher-quality sleep. Perhaps developing a sense of purpose in life could be as useful at improving sleep as the healthy habits above.

【推荐1】阅读下文并回答问题。

Holidays play an important part in our life. We work hard during the year, so we feel tired and stressed at times. We need holidays to relax, even if they only last for a few days. This is especially true for women. They could get away from their husbands, children and family for even one week in the year.

Holidays have many good results. Firstly, they can improve the economy (经济). If there were no holidays. people would have little time to spend their money. Secondly, holidays allow people to relax after working hard a whole year. During and after the holidays, people feel more relaxed and are full of energy; they then bring this energy to work when they continue working. Lastly, holidays help people learn how to enjoy life. Most people improve their relationships with their other family members during holidays.

However, holidays also have some bad sides. People couldn’t enjoy travelling because of the heavy traffic. Besides, people couldn’t have fun shopping because of too many people.     

Anyway, most people realize that they need holidays. I can’t imagine what people’s lives would be like if there were no holidays.
