Good sleep tips

Good sleep is essential for your good life. So I am interested in sleep science. I repeatedly quate some articles about sleep in this blog.

Now, I introduce this article below in which Christine Hansen mentions some tips about better sleep.

According to Hansen, these five essences below are crucial:

1. Take an hour to wind down before bed
2. Stop trying to calculate how much sleep you need
3. Consider what foods you are eating
4. Try leaving your phone in a different room
5. Take time to acknowledge thoughts and feelings that may keep you awake later as they happen

Each of them is well-known facts for practitioners about this region. Among them, I am interested in sentence 2.

Indeed, some people have sticky thought about the necessary duration of sleep. For example, a man feels anxious at 23 because he should take seven hours of sleep and he has to wake up at 6 o'clock in the next morning. But in reality, he need not sleep full seven hours today, according to Hansen.

I agree with her opinion. On the other hand, there is broad controversy regarding the necessary time of sleep. Recent studies suggest most humans have to sleep for eight hours every day for keeping their life optimized. In my sense, few people match this condition. Whether this hypothesis is correct is yet to be proven.
