Why does my face itch when it gets hot

Summer has arrived now, and the temperature keeps rising and getting hotter and hotter. It seems that as long as you leave the air conditioner, you will sweat all over. When the weather is hot, many friends will have symptoms such as itching on their faces. Why do faces itch when the weather is hot? What causes the itching on the face? Are there any good solutions and tips to relieve it? Let me introduce it to you in detail.

The incidence of various skin diseases caused by hot weather has increased rapidly, accounting for almost 80% of the outpatient visits to dermatology departments in various hospitals every day. In this regard, the reporter visited Dr. Liu Junlian from the Dermatology Department of the 306 Hospital. Dr. Liu said that the hot summer is the peak season for various skin diseases, especially the three more prominent skin problems are more common, so preventive measures must be taken in time. In the hot summer, people are particularly prone to sweating. Excessive sweating is not conducive to the normal breathing of the skin. If you do not pay attention to personal hygiene and do not pay attention to the details when in contact with skin patients, and the fungi grow fast and are easy to be infected in the summer, skin problems can easily occur. Therefore, if you already have some skin problems, you must take the right medicine; if you don’t feel any discomfort yet, then the best way is to know yourself and your enemy and prevent problems before they happen.

Beware of eczema if you sweat too much. People love to sweat in summer, and the most common skin problem is "summer eczema" (a general medical term) caused by excessive sweating. Doctor Liu said that in hot weather, sweat from the body is not excreted smoothly and accumulates in the skin, which can easily lead to skin diseases such as prickly heat, acne, dyshidrotic rashes, and sweat gland cysts. For example, wearing stuffy, unventilated clothes, sweating profusely after strenuous exercise, or poor ventilation of indoor air conditioners are all causes of eczema. Symptoms: The most common eczema in hot weather is prickly heat. Children who love to play and make trouble are particularly prone to it, which is divided into three types: white prickly heat, red prickly heat and pus-filled prickly heat. They are mainly concentrated on the neck, chest, back, elbows, and sometimes even on the forehead. At first, the skin just becomes red, and then slowly turns into large red papules that are itchy and painful. Eczema in adults is mostly acne and prickly heat rash. Young people have active endocrine system and their faces tend to be oily in summer. If they apply oily or greasy cosmetics, they are particularly prone to acne. The elderly often develop neurodermatitis due to itchy skin, which may be similar to the symptoms of prickly heat at first, but if they scratch hard, it will cause changes such as skin eczema, and even cause secondary bacterial infection, and the vicious cycle will continue.

Prevention and treatment: It is understood that the prevention of eczema is actually not difficult. As long as you pay more attention to the ventilation of the environment and the comfort of clothes, and keep your body clean and dry, you can reduce the occurrence of the disease. As for children, parents should bathe them frequently, avoid using alkaline soaps, and apply some powder after washing, especially on wrinkled areas such as the neck and armpits. Never squeeze the acne on your face with your hands. You can wash your face with sulfur-containing soap and warm water. Eat less sugar, peppers, onions, garlic and other foods, drink less alcohol, and eat more vegetables and fruits. When adults develop mild eczema, frequent bathing can make it disappear slowly. If the condition is more serious and the itching affects work and sleep, you need to see a doctor to avoid skin inflammation or even secondary infection, which will increase the difficulty of treatment. Susceptible groups: children, young people with plenty of energy, the elderly and obese people. The sweat from fungal infections soaks into the skin, and the dust flying in the air also adheres to the skin with sweat, which can easily lead to skin fungal infections. Fungi such as Staphylococcus and Streptococcus are particularly adapted to the hot and humid environment in summer and grow quickly on the skin. Therefore, pityriasis versicolor, ringworm, and folliculitis are all relatively serious skin diseases caused by these fungi. Symptoms: Doctor Liu said that the most common fungal infections in summer are various types of ringworm. We all know tinea pedis, also known as athlete's foot. Many people suffer from it and it occurs every summer. Because the area between the toes is moist, it is most suitable for the reproduction of fungi. However, if you scratch it with your hands, you may be infected with tinea manuum, which can then develop into onychomycosis, which is also called onychomycosis, which is quite difficult to treat. In addition to the common athlete's foot, there are also tinea capitis, tinea cruris and tinea corporis. Although you can avoid getting sick by keeping yourself clean, various skin diseases caused by fungi on your pets are becoming more and more serious.

Children and the elderly often have "close contact" with pets, and the fungi on the animals can be transmitted to the human body, causing ringworm to appear on the legs and body. In addition, pityriasis versicolor is also a skin disease with a high incidence in summer. It is a light brown spot that turns red and itchy when sweating. Prevention and treatment: Most skin diseases caused by fungi are not easy to cure and are contagious. They will relapse when the summer gets hot, so do not apply medicine casually on your own. You must treat them under the guidance of a doctor. At the same time, keep the affected area dry and ventilated, and do not wear tight clothing. Especially for the feet, try to wear breathable sandals, change shoes and socks frequently when sweating, wash them with warm water every day, and avoid burning your feet. Although fungal skin infections are contagious, Dr. Liu said that fungal infections are preventable. In addition to maintaining your own personal hygiene, people who have pets at home should also bathe, clean, or sterilize them frequently. If there is a patient with infectious skin disease at home, or if you go out to public places, then you should use your own slippers, bathtubs, towels, etc., do not mix them, and rinse and disinfect them frequently.

Susceptible groups: people who keep pets, diabetics, AIDS patients, patients taking immunosuppressants, the elderly and children with low immunity. Avoid sun exposure. Strong sun exposure can easily damage the skin and cause photosensitive skin diseases. Doctor Liu explained that this is mainly caused by the human body's strong reaction to sunlight. Excessive exposure to ultraviolet rays will cause the skin to produce a direct phototoxic reaction, causing skin inflammation of varying severity. Symptoms: People with dark skin have a strong ability to absorb ultraviolet rays and are not afraid of the sun. On the contrary, people with fair skin and those who are sensitive to light are more likely to suffer from photosensitive skin diseases. Prolonged exposure to sunlight on exposed skin can cause redness, swelling, and even blisters on the back of the hands and face. If the area exposed to the sun is very large, severe symptoms may be accompanied by chills, fever, fatigue, nausea, vomiting, and even palpitations or shock. In addition, although lupus erythematosus, freckles, etc. are not photosensitive skin diseases, they can be aggravated by exposure to sunlight. Prevention and treatment: Due to different individual skin sensitivities, some people can become sick after just a few minutes or hours of sun exposure. Therefore, prevention of photodermatitis mainly involves avoiding direct exposure to photosensitive substances and sunlight. Therefore, when going out, avoid the midday and afternoon when the sun is strong, and try to go out in the morning or evening. Also, when going out, be sure to hold an umbrella, wear a wide-brimmed sun hat, and apply sunscreen or sunscreen lotion. Susceptible groups: women, children, people who are allergic to sunlight
