The high temperature and scorching sun in midsummer

How “mature” have you been in the sun?

Last weekend, I made an appointment with my friends to play in the water.

Although I applied sunscreen when going out, the sun in Wuhan was too hot. When the body's own repair function

is not enough to resist the damage caused by ultraviolet rays, the skin will be sunburn

What is sunburn?

Sunburn refers to skin damage caused by prolonged exposure to sunlight. Ultraviolet rays emitted by the sun are responsible for sunburn. UV rays can pass through clouds, so sunburn is possible even on cloudy days.

Sunburn is more likely to occur in the following situations:

① Light skin color and hair color;

② Not wearing sun protection clothing or applying sunscreen in the hot sun;

③ Activities in snow, water or beach that can reflect sunlight;

④ Infants and children ;

⑤ Excessive drinking.

Symptoms of sunburn

1. Redness: Sunburned skin usually develops erythema 3-5 hours after sun exposure, reaching its peak within 12-24 hours.

2. Pain: may cause tenderness, tenderness, tingling, etc.

3. The skin temperature rises.

Erythema usually resolves within 3-7 days; blisters heal without scarring within 7-10 days. Scaling, skin flaking and tanning may be observed 4-7 days after exposure. Severe sunburn can cause blisters, severe pain, swelling, fever and other symptoms. Severe cases may present systemic symptoms such as headache, fever, nausea, and vomiting.

Skin sunburn should be taken absolutely seriously!

Sunscreen is not only to prevent tanning and sunburn. Overexposure to ultraviolet rays will cause a series of problems:

★ Accelerates skin photoaging, leading to dullness, wrinkles, spots, and plummeting appearance.

★ Induces skin diseases. Ultraviolet rays can also cause skin diseases such as polymorphic light eruption, phytophotodermatitis.

★ Increases the risk of skin cancer . When severe, can even cause tumors, such as basal cell carcinoma , squamous cell carcinoma , and skin melanoma. According to clinical research, if you have a history of sunburn, even just once, it will increase the risk of skin cancer. If you have sunburn more than 5 times, the risk of malignant melanoma will double.

DNA damage caused by ultraviolet rays is a long-term accumulation process, so the elderly are much more likely to develop skin cancer than young people. Therefore, I advise everyone to use sun protection, sun protection, sun protection!

has said so much, but how should you do sun protection?

One formula, do the ABC principles:

Avoid (avoid the sun), Block (do physical shielding), Cream (use sunscreen every day). If you do the above three points, sunburn will be far away from you. .

• Avoid (avoid sun exposure): It is best to avoid going out during the period when the sun is strongest, and try to stay in the shade when you must go out. During the day, ultraviolet rays are strongest between 10:00 and 16:00, so it is best to go out less often.
• Block (do physical sun protection ): choose umbrellas, hats, clothing and other hardware that meet UPF standards to block ultraviolet, visible light and even infrared . This is recognized as the most effective and practical sun protection method.
• Cream (Wear sunscreen every day): You must apply sunscreen well when you go out. You can't squeeze in a little bit and apply it randomly, then you think it's enough, you're done, and you're done.

Tips for applying sunscreen:

1. Before going out to bask in the sun, apply it 30 minutes in advance. Apply a sufficient amount, at least the size of a dollar coin for one face.

2. If you are going to do outdoor activities, like to sweat, or go swimming, you should choose a waterproof formula and increase the frequency of reapplying.

3. People with hair loss or baldness should pay more attention to sun protection on the top of their head, because this is an area exposed to direct sunlight and is also a high-incidence area for clinical actinic keratosis and skin cancer. It is best to wear sun protection and wear a hat.

4. Nowadays, everyone wears a mask when going out, but the UV protection of the mask is not enough, so you still have to apply it as usual.

Precautions after sunburn

1. Do not rub the skin because the cuticle has been injured. So cover it with a towel and don't wipe it casually. Also try to avoid using products such as body wash and facial cleanser when taking a bath.

2. Do not use ice cubes directly as it may cause frostbite. If the towel heats up, just pick it up, shake it and cover it again, or prepare a small bucket of ice water to re-soak the towel at any time; wrapping ice cubes in a towel will cause difficulties in execution (for example, the ice cubes fall out and the water keeps flowing). drop).

3. If you have a large area of ​​sunburn and are in constant pain, it is recommended to see a doctor immediately.

4. Avoid exposure to the sun again. If it is unavoidable, it is recommended to use clothing, umbrellas, etc. to cover; physical sunscreen lotion is more suitable.

5. When peeling, just let it fall off naturally. Do not tear it off.
