Health and longevity is the dream of many people, but, like many other things, health and longevity cannot be achieved overnight, and it needs to be accumulated bit by bit in daily life.

Get to know our bodies and learn the secret of keeping healthy. I believe everyone can become healthy and live a long life.

The favorite posture of the human body is not lying or sitting, but squatting.

Medical research has found that the squatting posture of human beings is very similar to that of the fetus in the uterus, and it is an instinctive posture for human beings to seek comfort and shelter. It can not only relax our bodies, but also give us enough sense of security.

In fact, besides the instinctive memory of the body, squatting can sometimes bring us many unexpected health effects.

Proper squat can help dilate arterioles and arterioles, reduce the peripheral resistance of the heart, improve the elasticity of blood vessel wall and effectively lower blood pressure.

Doing squats after sitting for a long time can relax muscles, move joints and promote blood circulation of lower limbs, thus reducing the harm to our bodies caused by sitting for a long time.

Squatting can enhance the range of motion of waist, hip, knee and ankle, enhance the flexibility of knee joint and delay the aging of joint.

Through the investigation of the lifestyle of some healthy elderly people, it is found that they are engaged in farm work, squatting by the pond to wash rice, wash vegetables and wash clothes ... which strengthens their waist and legs and achieves the function of keeping fit.

α -linolenic acid is a polyunsaturated fatty acid with three double bonds, an ω-3 essential fatty acid and one of the essential nutrients for human body. However, this extremely important nutrient cannot be synthesized by the human body and can only be obtained through food.

α -linolenic acid mainly exists in vegetable oils such as perilla oil and autumn hemp seed oil. If you only eat soybean oil and peanut oil at home for a long time, it is basically impossible to supplement, and your body will also lack α -linolenic acid.

α -linolenic acid is mainly beneficial to regulating blood pressure, blood lipid and blood state, and can nourish brain cells, especially suitable for people with old people and children at home. It is very beneficial to improve children's intelligence and reduce cardiovascular and cerebrovascular diseases in the elderly.

It is worth noting that α -linolenic acid is easy to oxidize at high temperature, so it is not suitable to heat it at high temperature when eating perilla vegetable oil or autumn hemp seed oil. Can be directly drenched in cooked vegetables and soups, and can also be used for cold salad or stuffing.

In addition, you can eat it with perilla vegetable oil and yogurt. This is the famous Johanna Budwig therapy, which is beneficial to clearing blood and nourishing blood vessels.

The humidity in winter is 30% to 80%; The humidity in summer is 30% to 60%. More than 95% people feel comfortable in this range.

The most comfortable indoor temperature for human body is 15- 18. If the indoor air is not circulating or the relative humidity is less than 35%, and the indoor temperature exceeds 25, the human body will start to absorb the external heat, and you will feel hot.

In the state of less activity such as rest and sleeping, the human body will feel more comfortable when the indoor relative humidity is between 50% and 60%.

28, when the relative humidity reaches 90%, you will feel the temperature reaches 34. This is because when the humidity is high, the water vapor content in the air is high and the evaporation capacity is low, so it is difficult to evaporate a large amount of sweat discharged by the human body and the heat in the body cannot be dissipated smoothly. Therefore, it will feel sultry.

The most beneficial drink for human health is not red wine that many people like to drink, or even cold boiled water that many grandfathers like to drink, but tea. Drinking tea is a habit that many long-lived elderly people will have. It has existed in the treatment of tea since ancient times and is the safest and most effective way to prevent diseases and preserve health.

Men often worry that their kidneys are not good, so they can drink more heather fruit tea, which can not only maintain the kidneys, but also delay the aging of the kidneys, which is very beneficial to the maintenance of the kidneys.

Heather fruit, also known as sorbus nigricans, is a typical black food, and black corresponds to kidney. Heather fruit tea, like black beans and black rice, is also a good product to care for the kidney. It is rich in anthocyanins and can effectively delay the aging of kidney function.

Women are often troubled by inflammation, whether it is mastitis or pelvic inflammatory disease, they can drink some dandelion mountain rose tea, which I believe will be of great help.

Dandelion is a kind of "natural antibiotic", which has a particularly good bactericidal and anti-inflammatory effect and is found in many Chinese patent medicines. Rosa roxburghii is a kind of wild hill rose, which is very mild, can relieve the coolness of dandelion, and is good at promoting blood circulation and regulating endocrine, which is very beneficial to women's breast health.

Most of the world-famous longevity areas are concentrated between 1200- 1500m above sea level.

The results of modern scientific research reveal the real reason of this mysterious phenomenon: altitude is an important factor affecting human health, because at this altitude, it has the most suitable air pressure, the densest negative oxygen ions and the most comfortable temperature!

Below 500 meters above sea level, the air pressure is high, the air density is high, it is hot and humid, and the burden of human function is heavy; On the other hand, in the plateau area above 2500m, the atmospheric pressure is low, and the oxygen content in the air is reduced, which makes it difficult for people to breathe and produces mountain reaction.

Normal people's heart rate is 70 or 80 beats per minute, but when the altitude reaches 1200m, people's heart rate will increase to 15%-20%, that is, it will increase by 7- 10, or even 15 or so, and the heart rate will accelerate at a low intensity.

Faster heartbeat 15-20% can promote and accelerate the metabolism of human body, correspondingly increase perspiration and accelerate the burning of fat, which naturally plays a role in losing weight, which is very beneficial for women to lose weight and shape, while the functions of thyroid, adrenal gland and gonad of men will be more active and many physiological functions will be enhanced.
