Why sleep is important and how to sleep better

It is well known fact that sleep is essential for human health, we are physically and emotionally restored by sleep. We spend a third of our lives sleeping. To benefit from all this time we spend asleep we need to know the way to do it right.

Steps to high-quality sleep:

Make sure the room is dark

Melatonin is a hormone made by the retina and brain while we sleep. When light hits the retina, even if the eyes are closed, melatonin stops being produced. The importance of this hormone is proven by many scientists.

In 2007, the research showed that men who received melatonin before going to bed doubled their growth hormone levels.

The importance of the hormone was also proven by Russian scientists studied the influence of melatonin on night's sleep quality. 40 patients with insomnia who took melatonin for 5 days participated in the study. Before taking the hormone, patients complained about difficulties falling asleep (90%), frequent awakening at night (70%), light sleep (60%), difficulty getting back to sleep after waking up at night (50%), and early morning awakening (65%). After taking supplements, all these indicators improved significantly: 90% of patients began to fall asleep faster, 85% began to fall into deep sleep without frequent awakening.

Stick to the routine

You should go to bed and get up at the same time. Our body appreciates us being consistent. Keep in mind that you shouldn't fall asleep later than 11 p.m. considering that this is the time when melatonin starts to actively release.

Get up early

According to scientists, larks are more successful and active people. In fact, the division into owls and larks is a notional concept. Owls need to put effort into trying to stop making excuses and start going to bed and waking up earlier. Research shows that only 50% of our tendency to be a lark or an owl is determined by genetics. The rest is a matter of discipline. Rising early will give you some extra time to get ready for the upcoming day without rushing and being in a hurry. Getting up early will give you an opportunity to do a quick workout, enjoy reading, meditate, set yourself up for the day and, of course, you will have plenty of time to prepare yourself a delicious breakfast.

Keep your bedroom cool

The most comfortable temperature for a good sleep is 68 degrees Fahrenheit.

Avoid heavy meals, drinking alcohol and smoking late in the evening

All of the above can negatively affect your sleep quality.

How much sleep do we need? For proper physical and mental activity, a person needs about 8 hours of sleep. People who sleep less than 6 hours have a greater risk of getting sick. That was proven by scientists from the University of California in San Francisco.

The University of Pennsylvania also conducted a large-scale study on sleep issues. 48 men and women who usually slept for 7-8 hours took part in the study. They were divided into three groups: the first group, people had to sleep for 4 hours a day for 2 weeks, the second - for 6 hours, the third - for 8 hours a day. As a result people who slept for 8 hours showed no disbalance regarding their well-being, while the participants from groups 1 and 2 gradually deteriorated their characteristics. After 2 weeks, people who slept for 4 and 6 hours had the same indicators as if they had no sleep for two days.
