In autumn, the sun also becomes fresh. Did you go out to bask in the sun? It's a loss not to bask in the sun! A number of studies have shown that reasonable exposure to the sun can help reduce the risk of cancer, heart disease, stroke, respiratory disease, etc. It is also good for stabilizing emotions and improving hormone levels.

People who do not often bask in the sun will inevitably encounter the following health problems

osteoporosis
90% of vitamin D in the human body is synthesized through its own skin after being exposed to ultraviolet light in the sun. It can promote calcium absorption in the human body and reduce the risk of osteoporosis.

Diabetes
Low levels of vitamin D due to insufficient sunlight can increase the risk of obesity and type 2 diabetes.

depressed
Sunshine can increase the secretion level of adrenaline, thyroxine and gonadotropin, which will effectively improve the bad psychology such as depression and mental depression, and prevent depression.

Multiple disease risks
Insufficient sunlight also increases the risk of heart disease, cognitive impairment, erectile dysfunction, prostate cancer, and mental illness. More exposure to the sun can help prevent many common diseases such as cancer, allergy, asthma, myopia, influenza, rickets, etc.

There are three key points to correctly bask in the sun

The key parts should be exposed to the sun, such as the head, back and legs.
● The head is the "meeting of all the Yang", which is the place where the human body gathers Yang qi. It can regulate the blood and smooth all the veins. Therefore, pay attention to making up for its deficiencies at all times.

● The back is the place where the governor of the human body circulates, which is the "sea of yang meridians". The governor is equipped with yang meridians. It is also the main part of the circulation of the Bladder Meridian of Foot Taiyang, which acts as a barrier against the invasion of exogenous pathogens. Therefore, the yang here should also be sufficient.

● "Cold starts from the foot". The legs and feet are the places where yin sinks. Many people's calves and hands and feet are cold, which means that the moisture is too heavy. They can usually bask in the sun.

Key people should always bask in the sun
The elderly with weak yang, congenital deficiency and chronic diseases should be exposed to the sun to help yang qi. In addition, people who do not often bask in the sun should take the initiative to increase outdoor activities.

Select the right time point
Too strong sunlight may lead to early age macular disease and skin cancer, so it is important to choose the right time. The best time to bask in the sun is from 8 a.m. to 10 a.m. and from 15 p.m. to 17 p.m. The "best sunshine period" is simpler and more effective to choose by using the "shadow principle". When the shadow length is shorter than the height, it is not suitable to bask in the sun, because the sunlight at this time is more "toxic". The vast majority of people can bask in the sun for about 20 minutes every day. Children should be shorter and the elderly should be longer. However, it is generally recommended that the sun should be kept within 30 minutes.
In autumn and winter, the time to bask in the sun can be extended appropriately. Don't bask in the sun through the glass, because the glass blocks most of the ultraviolet rays in the sun. It is better to bask in the sun outdoors or open the window.
