The thermostat of the human body is located in the hypothalamus of the brain, which plays the role of the human body's regulatory center and is responsible for biological rhythms such as body temperature, sexual intercourse, human circulation, diet, and alternation of day and night. It will measure the real-time blood temperature, receive temperature signals from the body and skin at the same time, and then give instructions to the skin blood circulation.
2. Is pain addictive? Interesting!
The pain center and pleasure center in the brain are next to each other, and the stimulation to the skin will be handled by them together. When the body feels pain, it will produce analgesic substances such as adrenaline, which can trigger escape response and stress response. These opium chemicals can anesthetize pain and make people feel happy. This phenomenon is also accompanied by sexual intercourse: orgasm will touch the boundary between pleasure and pain, and at this time people can experience chemicals similar to opium, so it may make people suffer from sexual addiction.
The function of sebum is to protect the skin.
Sebum is the second largest oil source of the skin, which plays a role in maintaining and protecting the skin. For the skin, sebum is equivalent to a nutritious skin cream mixed with various fats and waxes, which can keep the skin soft and give off a healthy light luster. Combing hair and head massage can increase the luster of hair, because sebum will be transferred from the head to the hair during combing. The most successful "public relations" case between you and sebum mainly focuses on the nose, that is, squeezing the pores on the nose with your fingers to squeeze out demodex sebum. It's like the unformed stool is shaped by the tubular intestine and finally becomes a sausage-like finished product. In short, whether it is a "sausage" or a worm squeezed out of a pore, the reason is the same. It is worth mentioning that the demodex sebum produced by each person per year is about 1 1 km. If you don't squeeze it by hand, it will spill oil, that is, you often see small oil droplets overflowing pores and evenly distributed on the skin, which belongs to the human body's own skin cream application system.
4. Can skin care products really control oil?
Large sebaceous glands are mainly distributed in the T-zone consisting of scalp, forehead and nose, chin, back and chest, while small sebaceous glands are sparsely distributed in arms and legs, which is also the reason why arms and legs are easy to dry. With the increase of age, the activity of glands will decrease obviously with the decrease of hormone level, and the skin will become drier. On the contrary, under the influence of acne or birth control pills, sebaceous glands tend to become larger and overactive, leading to serious sebum overflow. Many skin care products claim that their products can regulate sebaceous glands and effectively control skin oil production. It's sheer nonsense! Sebaceous glands are located deep in the skin, and oil is located in the second floor underground. No skin cream can penetrate here, and even prescription anti-acne drugs can do nothing about the excessive secretion of sebum.
5. How did the blackheads come from? It turns out that the culprit is androgen!
If too much androgen enters the blood, or the receiving station is too sensitive and too "flattering", sebaceous gland cells will be over-operated, resulting in a large amount of sebum accumulating at the mouth of the hair follicle duct, giving a big table to lipophilic pathogens. For example, fungi that can metabolize fat, after eating a lot, will secrete a lot of fatty acids, the residue of fat feast. Fatty acids will seriously stimulate the soft inner wall of pores, and in order to remove dirt, the cells in the pore wall will continue to increase. So the tragedy appeared, and a kind of keratin plug often formed at the outlet of pores to block the outlet, which is also commonly known as blackhead.
6. Be careful when using drugs
For sebaceous glands, we can intervene by taking isotretinoin orally, and this kind of retinoic acid derivative on the market is mostly in the form of soft capsules. It should be noted that oral isotretinoin is not completely without side effects, especially young women must know that vitamin A and its derivatives will bring serious harm to embryos. Therefore, if you want to have a child, you must stop the treatment for at least one month. Nevertheless, isotretinoin can be regarded as the savior of many patients. As long as female compatriots pay more attention (it is much easier for men), taking isotretinoin orally can not only cure acne, but also rejuvenate skin and prevent skin cancer. Although unfair, the effect has been confirmed by many studies. For adolescent patients, high-dose treatment (30 ~ 40 mg per day) is usually used for half a year, while adults are more suitable for long-term low-dose treatment (20 ~ 40 mg per week).
7. Diet adjustment can safely improve skin problems.
Obviously, the treatment with the lowest risk is diet regulation, so as to control the overproduction and inflammatory activities of sebum: say goodbye to the typical "civilized food" such as refined white flour, sugar, a lot of milk and trans fat, and eat more vegetables, whole grains, nuts, fish and fish oil rich in important omega-3 fatty acids. In addition, intestinal bacteria with anti-inflammatory effect can be obtained by ingesting some probiotics or cultured by themselves through a high-fiber diet. These can help you stay away from acne and keep your skin healthy.
8. Improper selection of skin care products will lead to pore blockage.
Long-term use of greasy sunscreen, day cream, cosmetics, hair oil and hair wax will lead to pore blockage and hinder sebum discharge, especially products containing mineral oil such as paraffin or silicone oil will double the pore blockage. Therefore, in order to avoid acne in cosmetics, the easiest way is to throw away all these fruits; For people who are prone to acne, choose products marked with "no acne ingredients" and "no blackheads". The decline of male hormones will make the body bloated!
Unfair, the decline of male hormone levels comes very late, and the testosterone levels of men who like sports and are slim will last longer. However, once the testosterone level begins to decline, men will easily get fat, and it is not uncommon to have a big belly and thin legs. Some elderly men are obese, not only in the abdomen, but also in the pubic mound. That is to say, the change of hormone level will shorten the penis (visually or actually) and enlarge the breast tissue. The decrease of estrogen level in postmenopausal women and testosterone tolerance in men will make the once beautiful "lush grassland" sparse.
9. Can melatonin solve the problem of insomnia?
Melatonin is like an all-around mechanic. It is not only an effective sleep hormone, but also makes people feel tired and then fall asleep. It is also an antioxidant, anti-cancer factor, anti-aging factor and even an efficient hair restorer. After nightfall, serotonin will produce melatonin. When we sleep, we will work tirelessly with colleagues in other gene maintenance centers to repair sunburned parts of the skin. Unfortunately, they don't provide five-star "magic service", which can't eradicate skin cancer and delay the appearance of wrinkles. However, without the basic "beauty sleep" service, we will age faster. ...
10. You need melatonin at night and serotonin during the day.
Melatonin can stimulate the immune system and use it to resist the invasion of skin cancer. Stress, lack of sleep, and turning on the light to sleep will all lead to low levels of melatonin in human blood, which is more likely to cause sadness and accelerate aging. In winter, many people feel tired and depressed because the melatonin level in the body is too high. The daytime is short, and sleep hormones are not completely decomposed during the daytime, so people become listless and weak, as if they were still wandering at night. In short, we need melatonin at night and serotonin during the day, so as to ensure the normal operation of the body.
1 1. How to choose skin care products?
You know, expensive often doesn't mean good. The characteristics that skin cream needs to meet include: easy absorption, no pore clogging, no mineral oil, and close to skin lipids. It is best to choose a skin cream that follows the principle of skin cell membrane structure and simulates the formula of human sebum, which can better assist the protective barrier of skin. Traditional emulsions and creams need emulsifiers to combine oil and water, which can easily take away our sebum and cause allergies. In addition, the formula that simulates human sebum will not clog pores, which is the "basic quality" of the cream, keeping you away from cosmetic acne.
12. Trans fatty acids are one of the chief culprits of acne.
Scientific research has found that trans fatty acids (trans fatty acids? Ure). Trans fatty acid is a bad and unhealthy fat, which mainly exists in industrial hydrogenated oils and fats. It is usually used as cooking oil in fast food restaurants, and sometimes used to make jam, potato chips, French fries, instant pizza and packaged cakes. These are just the tip of the iceberg. Trans fats can increase the risk of myocardial infarction and stroke caused by cis-fatty acids and trans-fatty acids, leading to an increase in blood pressure, and also play an unshirkable role in causing cancer, type 2 diabetes, premature skin aging and allergies. Not only that, trans fats can also promote sebum production and keratinization, which can quickly block pores and lead to acne. Due to the serious harm of trans fats, the United States has banned their use in food production.
13. Milk is harmful to adults.
Milk is not an ordinary daily food, it shoulders an important biological mission. After human or animal is born, the signal system contained in milk can promote the growth of babies, while adults have already stopped growing and developing. According to this, the researchers said: Although milk is rich in important amino acids, drinking a lot of milk is actually harmful to adults, because the hormones in it will stimulate the malignant growth of cells in the direction of tumors.
If acne patients can insist on eating a lot of fruits and vegetables, grains, nuts, seeds and organic fish without harmful substances, and avoid eating trans fats, white flour, sugar and a lot of milk, then the skin condition will be improved a lot in a few weeks, at least by one grade.
14. This is also the reason to advocate breastfeeding.
The further measure to prevent allergies is to breastfeed the baby completely before 4 ~ 6 months old (4 months is the deadline in Germany and 6 months is the recommendation of the World Health Organization), which is very important for the establishment of the baby's intestinal flora and immune system. Complementary food should be added after 6 months at the latest, which is helpful to exercise the baby's immune system. Moreover, the plant fiber decomposed by bacteria can enrich the intestinal flora of children and make the beneficial bacteria with protective effect spread continuously, thus effectively consolidating and strengthening the immune system and preventing asthma and allergic reactions.
15. Skin reveals heart
Many things in life are far beyond our imagination, and psychological factors will always have a great influence, which will be reflected in various physical symptoms. When we establish contact with others, when we feel love or hate, all intentional or unintentional psychological changes will be reflected, and skin is the display screen of these subtle changes-red face, pale face, goose bumps and sweating all over. Various external interventions on the skin, such as makeup, tattoo, puncture, Botox injection, wrinkle removal and cosmetic surgery, will change the original natural performance of the skin.
16. homemade shampoo
Self-made simple shampoo can not only stabilize the acidic protective film of scalp and inhibit pityrosporum, but also bring beautiful luster to hair: relieve dry hair scales fried like pine cones and make them soft and smooth. This shampoo is also suitable for skin wrinkles. Wrinkles are prone to inflammation, and from time to time, they will emit thick sweat and peculiar smell. The skin environment under the smelly gland is strongly alkaline, and acidification therapy is also very effective at this time. Formula 1 liter of water 1 tablespoon of apple vinegar, the best pH value is about 4.8. After mixing water with apple vinegar, apply it to the affected area without washing, and its taste will naturally disperse.
17. Anti-acne mask made of medicinal clay
Medicinal clay (Heller) has been famous since ancient times. Mud mask can absorb excess oil caused by sebum overflow, and is rich in minerals such as silicon, calcium, aluminum, iron, potassium, magnesium, sodium and titanium, and trace elements such as copper, zinc, nickel (beware of nickel allergy), manganese and selenium. Medicinal clay is also very popular in the treatment of gastrointestinal problems (aluminum is difficult to dissolve, so it will not cause harm to the body). In a word, medicinal clay can not only diminish inflammation, but also scrub and exfoliate to remove keratin embolism caused by blackheads. Ingredients 2: Preparation and use of warm water for soup spoon and medicinal mud (drugstore, health care product store or drugstore) Stir warm water and medicinal mud into a thick and uniform paste, and then apply it to the skin. After drying for about 15 minutes, wash with warm water, or gently massage in circles on the skin to achieve the effect of scrubbing and peeling. If the skin feels dry afterwards, you can apply some skin cream or use avocado for secondary care.
