Why is sleeping important?
Epidemiology research on millions of people tells us the same fact: the shorter the sleep, the shorter the life expectancy.
So, if you want to live longer and stay healthy as long as possible, you should sleep better.
Sleep should be the health care system we dream of: it’s the most democratic, free, and it’s not a bit of a cure.
In fact, sleep is very beneficial, Professor Walker has been lobbying doctors to prescribe sleep.
However, sleep must occur naturally, and the effect is best. Many studies have linked sleeping pills to increased risk of cancer, infection, and death
What happens to our body and mind if we don’t sleep?
Many diseases are associated with insufficient sleep. For example, Alzheimer’s disease, cancer, cardiovascular disease, obesity, diabetes, depression, anxiety, and even suicide.
Sleep can give our body and mind a complete “renovation.”
How long does it take to stay healthy every night?
In short: seven to nine hours.
If your sleep time is less than 7 hours, your immune system and your cognitive ability will begin to be affected. After 20 hours of continuous waking, you are affected and drunk.
One problem with insufficient sleep is that you don’t realize the damage it does to you. It’s as if the drunkard picked up the car key and left the bar, insisting that “I’m not drunk, I’m really not drunk”.
Why do we sleep Less and less?
If you look at the data of industrialized countries, we will find a clear trend: in the past 100 years, our sleep time has decreased.
If we sleep less, we will have a harder time getting into the REM phase. Interfering with REM is very harmful because it is vital to our creativity and to our mental health.
People are sleeping less and less for several reasons.
1. Insufficient knowledge. The scientific community knows how important it is to sleep well, but it has not been effectively communicated to the public so far. Most people don’t understand why sleep is important.
2. The pace of life. In general, we work longer hours and spend more time commuting. We left home very early, came back very late, and we also wanted to spend time with family and friends, watching TV… Finally, our time was swallowed up and sacrificed sleep.
3. Attitudes and concepts. Sleeping has an image problem. If you tell someone that you have been sleeping for nine hours, they may feel that you are lazy. Therefore, many people brag about how short they sleep each night. However, no one would say that babies who sleep a lot all day are lazy because we know that sleep is absolutely necessary for their development. However, this concept changes with age.
4. Environment. Now we live in a world that lacks darkness. However, we need darkness to release a hormone called melatonin that helps us sleep peacefully. Unfortunately, one of the side effects of social progress is that we are constantly affected by artificial light. This situation is exacerbated with the birth of LED screens.
5. Temperature. Another unexpected side effect of social progress is that we no longer experience the natural transformation of cold and heat within 24 hours. We all want a warm home environment, but we also need a little cool, let us go into sleep mode. Our brain and body need to lower the core temperature by about 1 °C so that we can relax and sleep in a natural way. Most of us have overheated the heating temperature: if you want to sleep well, you should adjust the temperature in your home to 18oC at night.
