Aerobic exercise can help us keep healthy, especially aerobic exercise has many positive effects on health, but many people who insist on aerobic exercise find themselves losing their hair. What's wrong with aerobic exercise?
Aerobic exercise alopecia 1 Many people may not know that losing weight by aerobic exercise may lead to alopecia, because we all know that aerobic exercise is very good for improving the body's resistance and promoting gastrointestinal digestion and absorption, but we are not aware of the possible side effects of aerobic exercise. In fact, aerobic exercise is the cause of hair loss, and fitness exercise is the cause of androgen metabolism. Promoting the administrative department of DHT and promoting DHT will lead to more serious hair loss.
What is the relationship between fitness exercise and hair loss?
1, fitness promotion into DHT
Physical exercise can improve the DHT level of the body. In the case of physical exercise, the level of androgen will increase, and DHT is produced by androgen and 5α reductase in the body. Recently, an overseas journal article made a scientific research on the relationship between male high-toughness fitness exercise and growth hormone, which lasted for 65438+February. The final result is that the DHT of fitness athletes with moderate compressive strength increased by 14 and 5% in March, and the DHT level of fitness athletes increased obviously in June. This is not good news for male patients with alopecia. An increase in DHT means that your hair loss will also increase and be out of control. Besides DHT, estrogen fusion protein (SHBG) also increased significantly. There is nothing wrong. Xiaoke can't take it out of context There are many athletes in the world who don't lose their hair, and most of the athletes who signed up for the Olympic Games showed normal growth hormone in routine physical examination.
2. Hereditary DHT protein kinase gene
At present, the medical community believes that there are genetic defects in the hair follicles on the head and forehead of male alopecia patients. There are many protein kinases of DHT in these defective hair follicles. Once they are fused with DHT, hair cannot be generated normally. In other words, to put it bluntly, the genetic gene of alopecia is the genetic gene that controls DHT protein kinase. This shows that players don't lose their hair because they don't have the genetic inheritance of hair loss; Although the metabolism of androgen (DHT) is normal, excessive metabolism of DHT protein kinase in genetic decision-making can also cause hair loss in fitness exercise.
3, hair pH pH imbalance
Jessica, a British biologist who studies hair scientifically.
Clemente stressed that not taking a bath or washing your hair after exercise is one of the key reasons for male hair loss. After exercise, the acid-base imbalance caused by the mixture of head sweat and vegetable oil will affect hair follicles, which will lead to atrophy and necrosis of hair follicles in the long run.
Strong physical exercise will aggravate the process of alopecia in patients with alopecia. Should we give up fitness exercise? Not really! As we all know, aerobic exercise to lose weight refers to fitness exercises that improve heart function and consume fat under the condition of sufficient co2 supply, such as running, swimming, football team, mountain climbing and so on. Strength training refers to the excessive high-speed movement of muscles under the condition of "insufficient oxygen", which is mostly fitness exercises with high compressive strength and strong instantaneity, such as dumbbells, weight-bearing squats and barbells. Scientific researchers have found that the androgen level caused by strength training is higher than that caused by aerobic exercise to lose weight. Aerobic exercise can accelerate the blood circulation system caused by weight loss, which is beneficial to hair.
Aerobic exercise alopecia 2 1. Does exercise really aggravate hair loss?
In fact, if you think about it carefully, many athletes do lose their hair, such as Zidane and Robben who play football, Jordan who plays basketball, Agassi who plays tennis and so on. Many sports superstars have not been spared hair loss. It stands to reason that athletes have scientific eating habits and are healthier than ordinary people. Why do they lose so much hair and even go bald early? There is a reason for all this. Hair growth is closely related to hormones. Under normal circumstances, human hormones are almost at a relatively peaceful level, but after long-term exercise or strenuous exercise, hormone secretion will increase, muscles will become stronger, male charm will be shown, but at the same time hair may also be affected.
2, the same exercise, why some people lose their hair and some people don't lose their hair?
The root cause is heredity! At present, it is theoretically believed that the hair follicles on the head and forehead of patients with androgenetic alopecia have natural defects and will become the target organs of dihydrotestosterone (DHT). DHT can inhibit the normal physiological function of these hair follicles, leading to abnormal hair synthesis, fibrosis around hair follicles and serious hair loss. Therefore, unless there is no DHT in the body or the DHT content is extremely low (such as women or eunuchs), the fate of hair loss is inevitable, which is hereditary hair loss.
3. If it is due to genetic reasons, why is the sudden hair loss so serious?
Because DHT generally becomes more and more in the body after 18 years old, you won't lose your hair before 18 years old, whether you inherit it or not, but you can see symptoms after 18 years old.
4. Which is more harmful to hair, anaerobic exercise or aerobic exercise?
Aerobic exercise: running, swimming, football, mountain climbing, etc. Exercise is mainly to enhance heart and lung function and burn fat.
Anaerobic exercise: barbell, squat, dumbbell, exercise is mainly to exercise muscles and directly exert pressure on muscles.
Anaerobic exercise can increase testosterone in a short time. Scientists have found that after a period of fitness, testosterone in the body will increase by an average of 25%, and the rising testosterone will be converted into DHT, which will further shrink hair follicles and aggravate the degree of androgen hair loss.
Aerobic exercise is mild and will not significantly improve hormone levels. Aerobic exercise will enhance blood circulation, cardiopulmonary function and oxygen carrying capacity of cells, which is conducive to hair growth. In fact, aerobic exercise is good for hair health.
Aerobic exercise alopecia 3 How long is the hair?
Hair grows in a repeating cycle of three stages. In the first stage-growing period-a new hair shaft is formed. It takes 2 to 8 years to nourish and grow by blood. The next stage is called the regression stage, which lasts two to four weeks. Hair is pushed out of the blood supply and stops growing. From the last two to four months to the rest period, the hair is no longer nutritious, but it will not fall off.
After the last stage, the hair growth cycle ends, and the first stage starts again, pushing out old hair shafts and forming new ones. As a natural part of this process, 50 to 100 hairs fall off every day so that new hairs can grow.
Causes of hair loss
When the hair growth cycle ends, the hair will disappear temporarily or permanently, but no new hair shaft will be formed. Stress, disease, hormonal changes, malnutrition and medication can all disrupt the growth cycle and lead to hair loss.
Some people will lose their hair about three months after the stress period of life begins. If the stress continues and things calm down again, hair loss will last for about three months, or even longer for some people. Some drugs for heart disease, hypertension and depression can cause temporary hair loss. Both men and women may experience hair loss caused by hormonal changes caused by aging.
Healthy hair
By maintaining physical and mental health, reduce the chance of hair loss caused by stress and physical health problems. During aerobic exercise, you will release endorphins and other feel-good hormones, which can make you happier and reduce the effects of stress.
In order to keep healthy, the American Heart Association recommends at least 150 minutes of moderate aerobic exercise or at least 75 minutes of vigorous aerobic exercise to keep the heart and blood vessels healthy. This can optimize blood circulation, reduce inflammation, and have a positive effect on your skin, hair and nails.
