"Two drinks before bed, relax and sleep well." Is this true? Modern people are tired during the day, and when they want to sleep well at night, they find that they can't sleep peacefully.
As a result, many people choose to drink some alcohol before going to bed to relax and help fall asleep. So, can a glass of wine before going to bed help you sleep?
The reason why drinking alcohol brings people a feeling of relaxation is because alcohol entering the human body will affect the central nervous system, causing brain activity to slow down, making people feel relaxed and sleepy, so drinking is indeed easy to fall asleep.
There is a substance in our brains that can produce drowsiness - adenosine. Under normal circumstances, adenosine increases, and drowsiness becomes stronger; Adenosine decreases and becomes awake. Alcohol can make adenosine increase rapidly, so it is easy to have a "sleepy feeling" after drinking. But adenosine will gradually decrease after falling asleep, so it is easier to wake up early in the second half of the night.
On the other hand, the metabolism of alcohol is an energy-consuming process, energy consumption will consume water, after falling asleep the body is still working at full speed, working overnight, which leads to the possibility of waking up thirsty in the middle of the night, and the diuretic effect of alcohol is easy to make people get up frequently in the middle of the night, so that the coherent sleep state is interrupted.
Others say that after drinking, the body is warm and it is easier to fall asleep. After alcohol is ingested, it can relax blood vessels and promote blood circulation, so people will feel warm after drinking. However, after drinking a lot, the body will sweat, increase the heat dissipation speed, but cause more heat loss, so remember to cover the quilt to avoid cold.
Sleep is a complex process, with wakefulness, rapid eye movement sleep, light sleep and deep sleep.
After drinking a lot, because the body has been metabolizing alcohol, can not really relax, so it is difficult to enter the deep sleep stage, resulting in sleep becomes very fragmented, light sleep increases, deep sleep decreases, rapid eye movement sleep time will also increase, the number and time of awakening will increase, the total sleep time is actually reduced, simply put, the overall sleep quality is actually declining.
Drinking a small amount of liquor before going to bed has a stimulating effect on sleep.
Baijiu brewed from pure grain, after microbial conversion, produces a large amount of glutamic acid, which is related to the concentration of adenosine. The results of the study show that glutamic acid has a calming effect on the human nervous system, and drinking a little liquor properly before going to bed can gently promote blood circulation and effectively help sleep.
Drinking heavily before bedtime is not advisable.
Drinking a lot before going to bed, accelerating blood circulation, leading to the enhancement of human sympathetic excitability, so that the human brain is in a state of excitement, this way of falling asleep quickly through paralysis rather than relaxation, can not relieve the fatigue of the body, improve sleep quality, such as the formation of dependence on alcohol to fall asleep will affect health.
So, what can we do before bed to sleep better?
1. Avoid strenuous exercise 2 hours before bedtime. Proper exercise helps sleep, but exercise before going to bed is easy to put people in a state of excitement and not easy to fall asleep.
2. Do not drink too much water before going to bed and avoid getting up frequently at night.
3. Take a hot bath before going to bed, or soak your feet, dim the room light, and let the whole person relax.
4. If you are suffering from insomnia, seek help from a doctor.
