Entering the summer when the weather is hot and humid, it is a favorable condition to cause many diseases, especially skin diseases. Heat rash in children is the most common disease. Here are the reasons why heat rash often occurs in the summer?

Heat rash is a condition in which the sweat glands are blocked causing sweat stagnation, the excretory ducts are prone to dust or clogged, causing the skin to become inflamed and small pink pimples appear on the skin.
In children, because the sweat gland ducts are not fully developed, in addition to hot summer weather, the child's body excretes a lot of sweat but does not get it out, causing stagnation of sweat and blockage of sweat glands.
Most children only get heat rash when it's hot, when the weather is cool, the rashes on the skin can go away on their own without causing any harm. However, there are also many cases of heat rash that cause children to itch, scratch a lot, causing skin scratches, further infection into pustules and boils.

2.1 Types of heat rash in children There are 3 types of heat rash in children, including:
Miliaria crystalina: Usually occurs in young children due to delayed development of sweat ducts. It is the mildest type of heat rash that affects only the top ducts of the affected skin. This type of heat rash does not cause inflammation, itching, or pain. It is usually caused by a high fever and leaves patches of skin that peel off when the illness goes away. Rosacea (miliaria rubra) is the type that occurs deep in the skin. The affected area appears red, itchy skin. Usually occurs due to hot and humid weather. Miliaria profunda: This type of damage is in the deepest layer of the skin, occurs due to severe damage to the sweat glands, often after a prolonged red heat rash. It is the least common type of heat rash. 2.2 Symptoms of heat rash Children appear small blisters growing in clusters, on the background of red skin. The child is itchy, fussy, irritable, and irritable. Broken children can cause skin abrasions, infection into pustules or boils on the skin. Common location: Heat rash is mainly found in places with many sweat glands such as in the forehead, neck, shoulders, chest and back, but can also be found in the armpits and groin.

Summer is the time when heat rash occurs a lot because:
The sweat ducts in children are not fully developed, so sweat has no way to escape. In the summer, when the hot weather stimulates the body to excrete a lot of sweat to avoid heat, a lot of secretion leads to sweat not escaping, causing blockage. Clogged sweat glands cause heat rash Sometimes in the summer when children are given clothes that don't absorb sweat or often wear diapers, or diapers that are too tight, sweat glands can also be blocked. . Summer is a time when bacteria thrive. Some bacteria that reside on the skin can also secrete mucus that clogs sweat ducts. Summer has been hot, if the child has a fever, the child is too active, the body will increase activity, which will increase the sweat production to help the body cool down. It is also the cause of blocked sweat glands.

It is necessary to wear clothes made of soft, light, airy fabrics that can absorb moisture in the summer. Avoid wearing too much, too tight, too small. When the weather is too hot, it is necessary to avoid exposing children to sunlight, using ventilation fans and air conditioners.

Because this is the time when the ultraviolet rays (UVA and UVB rays) are most active, it is easy to cause sunburn and burning of the baby's skin. In addition, more dangerous if exposure to ultraviolet rays can cause skin cancer. Besides, it is necessary to keep the baby's skin dry and clean. Do not apply a lot of cream or powder on the baby's skin because it will clog the pores, making it easier for the child to have a rash. Avoid exposing children to places that are too crowded and stuffy. When children have heat rash, avoid scratching the acne because it can cause skin infections. Heat rash in children or adults is common in hot and humid weather. However, it often occurs in children because the sweat glands in children are not fully developed.
