Do you want to hide in an air-conditioned room every day in hot summer?

In fact, it is a good health care method to go outdoors to bask in the sun at the right time. Let's learn from Liao Huili, deputy director of the Department of Geriatrics, the First Affiliated Hospital of Guangzhou University of Chinese Medicine.

Sunbathing helps to prevent diseases.

"Summer is sunny, sunny and sunny, which can prevent and treat diseases." Liao Huili pointed out that sunbathing is a very good health care activity. Most human diseases are caused by the decline of human immunity, and human immunity is the ability to resist external evils, which is closely related to human yang. In Huangdi Neijing, "Yang defends external consolidation" refers to Yang Can's resistance to external evil.

Many neighborhoods are familiar with "treating winter diseases in summer", which is a health care therapy according to the theory of "nourishing yang in spring and summer and nourishing yin in autumn and winter" in traditional Chinese medicine, which accords with the characteristics of the four seasons.

Liao Huili explained that "winter disease" refers to some diseases that are easy to occur or worsen in winter, such as bronchitis, chronic obstructive pulmonary disease, allergic rhinitis, insomnia, bone arthralgia, and physical deficiency and cold syndrome. "Summer treatment" means that these diseases are relieved in summer. In the remission stage, it is necessary to replenish qi and support yang, treat according to syndrome differentiation, and prevent the recurrence of old diseases in winter or alleviate symptoms.

Modern medicine also found that regular sun exposure can enhance the immune function of human body, increase the vitality of human phagocytes and reduce inflammation. Proper sun exposure can also promote blood circulation, make blood vessels healthier, promote bone health, enhance human metabolism and regulate the central nervous system.

Liao Huili pointed out that modern people have a fast pace of life, stay up late more, exercise less, love to drink cold drinks in summer, and love to turn on air conditioners, all of which hurt the yang, so allergic immune diseases are more frequent.

Sunbathing can improve sleep.

Vitamin D needed by the human body needs to be obtained by basking in the sun. Skin gets ultraviolet rays from sunlight to make vitamin D3, and then the body converts vitamin D3 into active vitamin D through liver and kidney, which promotes the absorption of calcium and phosphorus and the formation of bones, so vitamin D is also called "sunshine vitamin". Nourish Yang Can to prevent and treat osteoporosis in the elderly by sunbathing.

Sunbathing during the day can regulate the biological rhythm of the human body and help sleep at night. Sunbathing on the top of the head, back and palm during the day is helpful to sleep and treat sleep disorders at night. At the same time, under sufficient sunlight, the secretion level of adrenaline, thyroxine and gonad will be improved, thus effectively improving the negative psychology such as depression and mental depression.

Sunbathing can also enhance human immune function and increase the vitality of phagocytes. Ultraviolet rays in the sun have a strong bactericidal ability. Generally, bacteria and some viruses will be killed if they are exposed to the sun for half an hour or several hours. "Old cold legs" and rheumatoid arthritis should often come out to bask in the sun, which can well drive away the cold of the legs and relieve arthritis.

Sunbathing pays attention to these three points.

Liao Huili said that people should not bask in the sun except those who have mild skin diseases or are allergic to light, and most people can choose the right time to "get in close contact" with the sun. However, basking in the sun in summer is also exquisite, such as-

1. Attention time: 9: 00 a.m. 9:00- 10/0 and 4: 00 p.m.-5: 00 p.m. These two periods are characterized by more A-beam components in ultraviolet rays, which is a good time to store vitamin D, a "sunshine vitamin" in the body, and it can be dried for about half an hour every day.

2. Pay attention to the parts: according to personal circumstances, the head, back, hands and feet can be dried. However, excessive exposure can easily turn human moles into melanoma or skin cancer. When sunbathing in summer, you must wear a sunscreen to cover the mole.

3. Pay attention to clothes: it is best not to wear black clothes in the sun, take off your hat and gloves, and try to expose your skin to the sun. It is best to bask in the sun outdoors or on a spacious balcony, not through the glass window.

Liao Huili suggested that in addition to sunbathing in the dog days, you can also try some Chinese medicine treatments, such as "three-volt patch", "three-volt needle" and "three-volt tonic" to help "support the yang and consolidate the foundation"
