Why is it harder to get rid of fatigue by "sleeping" as you grow older?

Old practice, throw the conclusion first, please see the follow-up for children's shoes who are interested in seeing the details. First, the "fatigue" after growing up is different from that when I was a child; Second, the "sleep" after growing up is also different from that when I was a child.

A different sense of fatigue

When we grow up, we feel more and more tired and heavier. Not only physically, but also psychologically. This fatigue is everywhere, all the time. There will always be endless things in hand, complicated workplace relations and confusion about the future, which are consuming themselves bit by bit.

I dare not look through the circle of friends, which is full of glamorous lives of others, as if I was the only one living a small and humble life. Sometimes, just coming back from vacation, I still feel uneasy.

Those countless entanglements, frequent self-torture and endless self-criticism all make us exhausted.

It is said that the adult world is not resurrected, as long as you grit your teeth and stick to it. No matter how tired you are, you still have to face everything the next day, and you can't fall down or retreat.

Think back to the so-called "tired" when I was a child, which is what we often say. I just fell asleep after playing crazy, but my mind was empty after an important exam. That kind of fatigue, simplicity, simplicity, truth.

Modern social animals are prone to various sub-health states. There is nothing wrong with it, and the physical examination report also shows that it is nothing serious, but I just feel a little off, listless and particularly prone to fatigue. Simple analysis, these fatigue mainly comes from:

1 mental class. For example, work pressure, excessive tension, or sudden accidents, excessive mental consumption, and various problems beyond mental endurance;

2 physics class. Problems beyond one's physical strength, such as overwork, excessive exercise and continuous high-intensity work, lead to physical overdraft;

3 health category. Some people suffer from insomnia, some people overuse their eyes, some people suffer from malnutrition, and some people have mental disorders such as depression and anxiety.

The comprehensive "fatigue" caused by various situations can obviously not be eliminated by simply "sleeping".

Sleep differently.

For the above reasons, it is increasingly unrealistic for us to rely on a "big sleep" to eliminate fatigue. Sometimes, even if I really sleep for ten hours, I still feel tired and listless when I wake up.

Especially on Sunday night, the thought of going to work the next day and facing a week's work is full of anxiety. Moreover, every time the emo in the middle of the night makes people collapse, they can't sleep at all under all kinds of emotions. When fidgeting, they have to take out their mobile phones from time to time, and there are still a few hours before getting up for work ... which further aggravates insomnia.

Sleeping is a very relaxing thing. But the reality is that more and more people are troubled by sleep problems-

Some are "revenge staying up late": I am too busy during the day to sleep at night, chasing dramas and playing games, and lying to myself after playing for a while, resulting in insufficient sleep. In the long run, it will lead to poor energy, emotional instability and easy rage during the day.

Some are pathological long-term lack of sleep, which is even more harmful. Many studies have found that short sleep time is related to a variety of cardiovascular adverse consequences. Insomnia, dreaminess, insomnia, poor sleep quality ... You can feel the madness and despair caused by sleep problems without too much description.

To make matters worse, sleep problems are sometimes a vicious circle. The more I can't sleep, the more anxious I am. The more anxious you are, the more you can't sleep. You can't sleep well.

Recently, a sleep evaluation platform in the United States conducted a sleep data survey. The survey results show that it takes an average of 1 hour to fall asleep after playing mobile phone for 8 minutes before going to bed.

I believe many people have this experience: before going to bed, they only plan to watch 10 minutes of mobile phones, and then an hour passes in the blink of an eye, and then the more they play, the more energetic they are. This is because, as long as the endogenous photosensitive optic nerve cells in the retina are stimulated by blue light for 8 minutes, the body will be excited more than 1 hour, causing confusion of the biological clock. Mobile phone screen is the source of blue light.

I have to mention dopamine Dopamine is a neurotransmitter, it will send you exciting and happy information to keep you awake, and it is also related to "addictive" behavior. Playing mobile phones before going to bed (such as playing games and playing small videos) makes you feel excited, dopamine secretion increases, you are more excited, and dopamine is secreted again ... so, I stayed up late.

When sleep deprivation and physical and mental fatigue occur, the brain will secrete more dopamine to stimulate the body to stay awake.

This is the reason why the more you play mobile phones and stay up late, the more energetic you are.

Melatonin can shorten sleep time, prolong overall sleep time and improve sleep quality. Melatonin has a circadian rhythm. The secretion of melatonin is influenced by external light and brightness. When the outside light is bright or blue light is sufficient, the brain will inhibit the secretion of melatonin; When the light is dim or the blue light is insufficient, the brain will stimulate the secretion of melatonin. People who procrastinate before going to bed, playing mobile phone before going to bed, will affect the secretion of melatonin. These will have a great impact on the quality of sleep. Now in order to improve insomnia, some suitable people can take melatonin to adjust.

Rory said so much, in fact, to tell you that it is not as simple as washing-going to bed-sleeping when we were young.

We didn't have cell phones at that time. Even if we peek at novels under the covers with a flashlight, we won't give up for a few days. Since we have a mobile phone, it has become our normal state to stay up late playing games and chasing dramas, and sleeping has become a luxury. I feel that I have been sleeping for a lot of time.

But in the final analysis, no matter what troubles we encounter and how many complicated and thorny problems bring us "fatigue", we all hope to be kind to our bodies, at least, at least give ourselves a better sleep as much as possible, so that our bodies and brains can provide us with energy and energy the next day, continue to upgrade, play tricks in life, and don't give up halfway and leave.
