The proverb "It is better to eat ginseng than to sleep for five nights" tells the true meaning of sleep. If you don't get enough sleep for a long time, it will not only affect your study, but also make some students feel depressed and tired.
There is no health without sleep, and sleep is an important part of the rhythm of life. Insufficient sleep, not only the body consumption can not be supplemented, but also the internal and external environment will be unbalanced due to insufficient hormone synthesis. More importantly, sleep affects human immune function. Scientists believe that if you want to be healthy, you must reassess the impact of sleep on health. Often burning the midnight oil, or playing cards and watching TV all night is very harmful to your health.
Professor Berry Darby, an immunologist at the University of Florida in the United States, has conducted a series of studies on sleep, hypnosis and human immunity, and concluded that "sleep can not only eliminate fatigue and make the human body generate new vitality, but also has a close relationship with improving immunity and the ability to resist diseases". After Professor Darby trained 28 experimenters in self-hypnosis, the results showed that T lymphocytes and B lymphocytes in the blood of the hypnotized experimenters increased obviously, and these two kinds of cells were the main force of human immunity. At the same time, scientists have found that subjects who practice hypnosis show stronger self-confidence, self-esteem and independence in the face of daily stress.
In addition, from 10 in the afternoon to 2 am, it is the most active time for cell death and regeneration in human body. At this time, if there is insufficient sleep, cell metabolism will be affected and people will accelerate aging.
People who stay up late for a long time and don't get enough sleep, even if they sleep for 8 hours the next day, it is difficult to recover their losses.
But mental workers are prone to insomnia, which makes people feel tired and anxious. They are afraid that insomnia will affect their health. In fact, what really affects their health is not insomnia, but anxiety. Anxiety can interfere with quiet rest and make it more difficult for people to fall asleep. According to the physiologist's observation, when you can't sleep, as long as you relax your whole body muscles and lie in bed with your eyes closed, the energy consumed by your body and the harmful substances produced are almost the same as when you are asleep. Therefore, don't worry about insomnia, be generous, and it is important to find the cause of insomnia. There are many reasons for insomnia, such as anxiety, depression, pain, illness, excessive fatigue, poor sleeping environment (such as noisy, too bright, sultry, cold, unsuitable bedding or pillow, etc. ), it will affect sleep.
To prevent insomnia, in addition to trying to eliminate or avoid the causes of insomnia, don't drink strong tea, coffee, wine, smoke, watch thrillers and TV before going to bed, so as to avoid excessive excitement affecting sleep.
What are the advantages and disadvantages of teenagers? Do some sex when you are young, but you can't do it when you are old.
Teenagers often see the harm of * * to the body, the symptoms and harm of * *
The phenomenon of * * * began with
It occurs in childhood or adolescence, because during this period, life is on the uphill road of growth and development, which is the most vigorous period. In addition, it is full of innate energy, so it will not stand up even in a short time.
That is, seeing adverse reactions. Otherwise, everyone can find the harm as soon as possible and cut it off consciously. This is the insidious place of * * *. The harm of * * * is gradually revealed after long-term accumulation, that is to say, once you see obvious bad symptoms,
It often means exhaustion, and it is impossible to try to recover in a short time.
The adverse reactions of * * * are briefly listed here, and most of them are common to users of * * *.
* * * People's early feelings are physical weakness, mental fatigue and laziness.
Gradually began to appear white hair. Initially, it first appeared in the brain vortex above the head, and then gradually spread around. (Usually habitual * * *, white hair will appear within 5 years, but the phenomenon of individual hand prostitutes is not obvious) At the same time, scalp grease
Dandruff is exuberant and thickened. Long-term development gradually turned to hair loss, also starting from the top of the head. (Usually habitual *** 10 years will appear, and individual * * * phenomena are not obvious. )
Premature ejaculation, usually manifested as * * * the time is getting shorter and shorter, from * * * to * * * it ends soon. (Generally, sexual habits will show up in about 5 years. )
The prostate is abnormal. Usually * * * can experience obvious manifestations around 10, such as urinary bifurcation (it can't be said that all urinary bifurcation is related to * * * and prostate, but it is common for long-term * * * users).
Prolonged sweating in genital area. * * * Long-term sweat is sticky and greasy, which breeds sludge and bean dregs. Sweaty and smelly.
Also accompanied by bad breath, yellow teeth are not white. People who are used to it all the year round even have dental caries, and most of them are in the upper teeth.
Oral ulcers are very prone to occur, and a slight scar on the basic tongue will develop into oral ulcers or even self-ulcers.
Easy to sweat, sweat secretion in midsummer or high temperature environment is significantly higher than others. In addition, people who exercise for a long time, such as going upstairs, will have a state of breathing and fatigue.
The interval between stools becomes longer.
In addition, the face of a long-term prostitute is abnormal. Or pale or gloomy. The figure is not normal, either thin or swollen.
There are several other phenomena. If you are used to * * * when you are young, your ears will grow out slowly, which shows that the proportion of your ears in your head is slightly different from that of normal people. Ears are obviously small.
These are just physical manifestations. Besides, masturbation can also lead to personality changes.
Long-term habitual masturbation leads to deficiency of kidney essence, from which personality gradually changes into introversion, lack of vitality, even loneliness and social fear. Mental state and personality are actually related to the internal organs, so it is difficult to adjust personality out of thin air. It is not easy to make a person with kidney deficiency brave.
And habitual * * * people often have a poor venue, which may be related to the dissipation of their own essence. The so-called "field" refers to a potential charm. For example, a beautiful and healthy girl just stands.
You'll feel comfortable around her. An excellent person, even if his appearance is not outstanding, will feel relaxed in contact with him. And a long-term habitual prostitute, others will have an unnatural feeling when approaching it, and associate with it.
There will be embarrassment. Often marginalized in social situations. Only people who have experienced it for a long time will feel this way.
As a result, from the habitual long-term development, it has become youth and looks young.
White hair and even hair loss, bad breath, yellow teeth. Weak and incompetent. Depressed, withdrawn, unsociable, cowardly and even obscene. In this state, there is great pressure to gain a foothold in society. Even positive.
Constant marriage and love will be greatly hindered. So * * * people have a strong * * *, but they are lewd and love beauty in their minds. But in reality, it is difficult to get the favor of the right woman. The quality of itself can hardly decide anything.
Opportunity. Even * * * people themselves simply lack the confidence and courage to contact the right woman. And personality and physical condition will naturally lead to a career that will not be smooth sailing, so the adulterer began to rely on his parents to live, but
But if you leave your parents to support the world alone, you will see bitter fruit.
In addition to the above, there is another phenomenon, the basis of which is still unclear, but the phenomenon exists. In an environment where * * * often happens, such as at home,
Pay attention to the status of family members, such as health, career, harmony and so on. In the environment where sexual intercourse often occurs, it is often full of disharmony. This may be that the so-called "Feng Shui" has gone bad. Take this.
People who have experienced it for a long time can experience it for themselves. Here, we don't say whether this phenomenon has a basis. In short, we can speak by implementing our feelings.
It can be seen that the harm of masturbation is real, but the most fatal shortcoming of young people is lack of experience. People who haven't experienced it may not believe it completely, but they have to bear the consequences whether they like it or not.
Self-help measures for long-term prostitutes. Cut off * * *, recover, and return to the blessing at an early date.
