When is the best time to bask in the sun in spring? In recent years, people pay more and more attention to their health. Many people will have dinner or sunbathe with their families in the warm spring season in bloom. Sunbathing is not only comfortable, but also beneficial to their health. So when is the best time to bask in the sun in spring?

When is the best time to sunbathe in spring? It is best to sunbathe in spring at 10am- 1 1am. Because the ultraviolet rays in the sun are low during this period, it can make people feel warm and soft. Sunbathing not only makes people feel comfortable, but also has a good health care function. Sunbathing can supplement vitamin D, promote the absorption of calcium and strengthen the body. Sun-drying the back can dredge the back meridians, which is good for the heart and lungs. Drying limbs can dispel the cold of legs, accelerate the absorption of calcium and prevent osteoporosis.

It is effective to sunbathe in three periods.

The first stage is 7-9 am. At this time, the sunshine is mainly warm and soft infrared rays, and the ultraviolet rays are relatively weak. High-temperature infrared rays can warm the body and promote blood circulation and metabolism.

The second and third stages are 9- 10 in the morning and 4-5 in the afternoon respectively. The radiation characteristics of these two periods are that there are many components in one beam of ultraviolet rays, which is a good time to store vitamin D, a "sunshine vitamin" in the body; At the same time, it can also promote the absorption of calcium and phosphorus in the intestine, enhance physical fitness and promote normal calcification of bones.

Don't protect your child from the sun.

Some parents are afraid that their children will catch a cold and put on hats, gloves and masks, but they don't know that it is difficult to achieve their goals in the sun. Children sunbathing should expose their skin as much as possible according to the temperature conditions at that time.

Don't take a bath after exposure.

It is best not to bathe children after sunbathing. Because the substance "7- dehydrocholesterol", which synthesizes active vitamin D in human skin, will be washed away when taking a bath, thus reducing the role of promoting calcium absorption in human body.

Put on red clothes and bask in the sun.

It is best to wear red clothes when basking in the sun, because the long-wave radiation of red clothes can quickly "eat" the short-wave ultraviolet rays with strong lethality. It's best not to wear black clothes.

When is the best time to sunbathe in spring? 2 Moderate sunbathing has many benefits to human body, such as preventing and treating skin diseases, supplementing calcium, strengthening the body and so on, as follows:

1, prevention and treatment of skin diseases: UVB contained in sunlight, properly irradiated on the skin, can kill bacteria on the skin and enhance the skin's resistance. The more common psoriasis and eczema can be relieved by proper sunshine exposure;

2, enhance physical fitness: moderate sun exposure can enhance the body's resistance to pathogens such as viruses and germs, and increase the vitality of human phagocytes;

3, calcium supplementation: human exposure to sunlight can promote the synthesis of vitamin D in the skin, which is conducive to the absorption of calcium and phosphorus, the deposition of calcium in bones, the prevention and relief of osteoporosis and fractures, and the height growth of children;

4, promote metabolism: infrared rays in sunlight can enter subcutaneous tissue, play a role in keeping warm, can promote blood vessel expansion, accelerate blood circulation, and accelerate metabolism, especially suitable for pregnant women and other people who are negligent in activities;

5, relieve stress: moderate sun exposure can relieve the body's nervousness and improve the discomfort caused by depression and excessive pressure.

However, we should also pay attention to sunbathing, choose more mornings and afternoons, and avoid sunbathing in midsummer and at noon when the sun is strongest to prevent heatstroke and sunburn.

When is the best time to bask in the sun in spring? Doctor reminds: Late spring and early summer are the most prone to sunburn.

"At this time of year, many patients with solar dermatitis report to the skin clinic," Zhong Jinbao said. Solar dermatitis, also known as "sunburn", is an acute phototoxic reaction of the skin after intense sunlight irradiation. The pathogenesis is related to a series of allergic reactions caused by the release of various inflammatory mediators by dermal cells after excessive ultraviolet irradiation.

Exposed skin will appear erythema with clear boundaries. Mild sunburn can cause redness and itching. In severe cases, blisters and edema will appear. After the sunburn becomes shallow and deep, it will peel off and may have pigmentation. Therefore, if you have been in the sun for a long time, your skin will be red and itchy. Pay attention to whether you are sunburned or not, and pay attention to sun protection.

Liang Fengxing, an attending Chinese medicine doctor in the Department of Traditional Chinese Medicine of Guangzhou Institute of Dermatology and Prevention, pointed out that Miss Zeng was outdoors for a long time. The sun was fierce that day, and the ultraviolet rays near the lake were strong. At that time, she did not do any physical sun protection or apply sunscreen.

In addition to taking antiallergic drugs, topical deuterium oil cream and diphenhydramine cream, plus oral Chinese medicines such as expelling wind and relieving itching, invigorating spleen and eliminating dampness, patients were also told to pay attention to sun protection during treatment to avoid sunburn again, and then symptoms gradually improved.

Solar dermatitis is more common in late spring and early summer for the following reasons:

1. The temperature is not high in spring, and many people think that the ultraviolet rays are not strong, but in fact, the ultraviolet rays are relatively strong in spring;

2. Just after the end of winter, the skin melanin decreases, and the sensitivity to ultraviolet rays is relatively high;

Spring is just right, everyone has a strong desire to go outdoors, but the awareness of sun protection is usually not very strong. A combination of various factors can easily cause sunburn.

Liang Fengxing introduced that solar dermatitis is common in children, women and people traveling near the equator or at high altitudes. In snow-capped mountains, coasts, beaches and lakes, ultraviolet rays will become more intense because of reflection. Before going out, everyone must take good sun protection measures.

Sunscreen in spring, do you use sunscreen correctly?

Now is the worst season for sunburn,

What about SPF50/PA+++? The most exclusive sunscreen?

The answer is: no.

After all, the higher the sunscreen level, the thicker the texture of sunscreen may be, which will increase the burden on allergic skin in spring, or it is not appropriate to choose sunscreen with too high a level in spring.

Liang Fengxing suggested that people who often stay indoors in spring should choose SPF 15/ PA+ sunscreen, and if they want to go outdoors, they can choose SPF25/PA++ sunscreen. If you don't sweat much indoors, applying sunscreen once a day is almost enough. If you want to stay outdoors for a long time, it is recommended to apply sunscreen 30 minutes before going out, and then every 1~2 hours.

Before buying sunscreen products, you should pay attention to whether it is suitable for your skin and whether it will cause allergies. The specific method is to try rubbing on the elbow and behind the ear for 24 hours, because some allergic symptoms are delayed. People who are allergic to sunscreen products are advised to take good care of things that block the sun, such as wide-brimmed hats, thin long sleeves and scarves in summer.

If the skin feels irritating and burning after being exposed to the sun for a long time, it is recommended to do some post-sun remedial measures at home, such as washing the skin with clear water, applying hydrating mask, and using post-sun repair products such as aloe vera gel or mung bean paste. In addition, you can eat more fruits and pay attention to some allergic "hair products", such as leeks, seafood, beef and mutton, spicy food, tobacco and alcohol.

For spring picnics, it is recommended to avoid eating these foods.

Liang Fengxing reminded that it is particularly noteworthy that there are many "legal" foods in spring, such as coriander, Toona sinensis, Sophora japonica, pineapple and mango. , are "light-sensitive food". After eating them, it is more likely to cause serious sunburn.

Therefore, when enjoying the spring sunshine outside, you should pay attention to avoid eating the following common "photosensitive foods"-

Fruits and vegetables: such as Sophora japonica, Chinese milk vetch, Chinese cabbage, grey vegetables, lettuce, fennel, amaranth, shepherd's purse, celery, radish leaves, spinach, buckwheat, coriander, safflower, rape, mustard, fig, citrus, lemon, mango, pineapple and so on.

Seafood: snails, shrimps, crabs, mussels, etc.

In addition, if you take photosensitive drugs, such as sulfanilamide, chlorpromazine, griseofulvin, etc. Long-term exposure should also be avoided.

So, are there any foods that belong to the "Sun Protection Food List"? Liang Fengxing recommended that you can eat some foods rich in natural antioxidants, such as tomatoes (rich in lycopene), nuts (rich in vitamin E) and green tea (rich in tea polyphenols). Can help improve the skin's "sunscreen ability" and reduce sunburn and tanning.

Sunbathing is for health and comfort.

Many folks believe that sunbathing in spring helps to stimulate the pulse and nourish the yang, especially sunbathing at Baihui point above the head and sunbathing on the back at noon, which is of great benefit to "nourishing the yang in spring".

Liang Fengxing reminded that in spring, if you want to achieve the purpose of health preservation through sunbathing, you should pay special attention to the following points:

1. Generally speaking, the ultraviolet ray is strong at noon, and the time in the sun should not be too long, and it is appropriate to control it in 20~30 minutes;

2. Those who haven't tried sunbathing before from 1 1 to 1 at night are advised to try sunbathing for 5 minutes first, and there is a gradual adaptation process. If you feel a little dizzy after five minutes in the sun, don't bask in it again and put on your hat at once. It is recommended to dry after meals.

The temperature is changeable in spring. If you feel the cool breeze blowing, you should keep warm to avoid catching a cold.

4. Patients with a history of solar dermatitis should not use this method for health preservation.

5. You can choose the time to bask in the sun flexibly according to your comfort. For example, choose 9 am to 12 am and 3 pm to 5 pm, and the sunshine is mild.

After basking in the sun, you can make soup with heat-clearing soup materials such as Ophiopogon japonicus and Polygonatum odoratum. On the one hand, it can replenish water, on the other hand, it can also play a health care role in nourishing yin and moistening lung.
