Many people like to drink a cup of milk before going to bed, which is thought to help sleep, but in fact, milk helps sleep only play a role in placebo.
Milk does contain tryptophan, and the brain can indeed use this compound as a main raw material to synthesize a substance called serotonin. Serotonin can suppress our thinking activities and make us drowsy.
But we must know that our body has a blood-brain barrier to prevent many substances in the blood from entering our brain, thus protecting the brain.
So the cup of sleepy milk that I drank at night, the tryptophan inside must first enter the bloodstream, and then enter the brain through the blood-brain barrier. The process is still tortuous.
So it seems that drinking a cup of milk before going to bed, it is not so easy to get the tryptophan into the brain tissue quickly. Moreover, the total amount of tryptophan contained in it is not enough to change the body's hormone levels. Therefore, in fact, drinking milk does not help sleep.
The above is a serious face of science, and what I want to say is that it will be scorned by many popular people.
- Not a science, just a dividing line of personal opinion -
If you believe that drinking milk will help you sleep, and after you have finished drinking milk, the quality of your sleep has improved: you fall asleep quickly, wake up and go to sleep, have less dreams, and wake up.
If you are in this state, then my advice to you is to remember to brush your teeth after drinking milk, and pay attention to the dietary balance every day.
Why do I stop stressing that drinking milk does not help sleep? This is because I feel that since you already think that drinking milk can help sleep, and the fact that drinking milk itself is not harmful to you, then let's drink it.
As long as you pay attention to oral hygiene, and add the milk before going to the daily diet plan, don't unknowingly consume too much energy, which leads to obesity.
And this question was asked when the director of the Central Radio's Voice of the Old Times interviewed me. I told her quite frankly that if the elderly are already convinced and effective, then let them drink milk. In any case, the general intake of milk in the elderly is insufficient, and as long as it is effective, drinking milk is much better than eating melatonin and sleeping pills.
Of course, if you have insomnia caused by a disease, you should still see an outpatient clinic. In this case, don't try to help the milk. Well, yes, even if it feels useful, you still have to go to the doctor.
