It is a known fact that colors have an impact on our health. We use colors to describe our well-being. We could be “in the pink of health”. However, we could be “off-color” or we may be “feeling blue”. 【小题1】

Research has found that colors can affect how we feel emotionally. If you go to a room that is painted just black, it can lead to depression. Experts have warned that we should avoid decorating any room entirely in black. A room that is painted totally white is also depressing as white is associated with totally clean environments like hospitals and bathrooms. 【小题2】

The measure of a good night's sleep is usually based on two things—the amount of time spent sleeping and the quality of that sleep. But now researchers say there is a third thing that matters even more than the other two when it comes to keeping good sleep habits, and that is having a regular bedtime.

A study has found that going to sleep and waking up at the same time every day have an important effect on one's health. Adults who stick to a regular bedtime tend to weigh less, have lower blood sugar and reduced risk of heart disease.

The researchers studied the sleeping habits of 2,000 adults with an average age of 69. They found that people with greater irregularity in their sleep patterns tended to go to sleep later at night,feel sleepy and sleep more during the day, and experienced reduced light exposure. These people were also more likely to be stressful. Among the three kinds of sleep problems, sleep regularity was the most strongly associated with health.

Of course ,there are many people for whom this may be impossible, such as night-shift workers or those with late-night duty. But for those who don't have mandatory(强制的) reasons to stay up late, they should make an effort to go to bed at the same time every night. Skip the late afternoon coffee.Get off the phone.Try this calculator to figure out the best bedtime.
