How to relieve itching from prickly heat in children

Heat rash in children is primarily caused by blockages in the sweat ducts, due to the poor development of neonatal sweat ducts, a humid and hot external environment, and prolonged bed rest. Based on the appearance of the heat rash, it can be categorized into white heat rash, red heat rash, pustular heat rash, and deep heat rash. Red heat rash can feel itchy and burning; pustular heat rash can cause burning, itching, and pain; white and deep heat rash do not typically present noticeable symptoms. When a child's heat rash feels itchy, topical medications can be applied for relief. Local cold compresses or ice packs can also be used to alleviate itchiness and pain. Naturally, providing a cooler environment for the child is beneficial, including frequent baths to help clear the sweat ducts.

Are heat rash and prickly heat the same?

Heat rash, also known as miliaria, is actually what is referred to in medicine as herpes simplex. It is different from prickly heat. Herpes simplex is caused by a viral infection, specifically the herpes simplex virus. It is characterized by clusters of small blisters and often occurs at the junctions of skin and mucous membranes. It is self-limiting but tends to recur, especially when the immune system is weakened. On the other hand, prickly heat occurs in the hot summer months when high temperatures and humidity make sweat evacuation difficult, leading to narrow and blocked sweat ducts, which results in prickly heat. It is usually intensely itchy. Thus, it is advisable to avoid rapid changes in skin temperature, such as moving from sweating heavily to suddenly entering an air-conditioned environment. This can cause sweat glands to close while sweat is still being produced heavily, leading to prickly heat. Treatment for herpes simplex involves antiviral therapy, whereas treatment for prickly heat primarily involves cooling, inducing sweat, and astringent measures.

What medicine is used for prickly heat?

Prickly heat is a common skin disease that often occurs in summer. For the treatment of prickly heat, we divide it into systemic treatment and topical treatment. Systemic treatment mainly involves taking antihistamines orally, such as loratadine tablets, when itching is severe. If there is a pus infection, it is recommended to use antibiotics for treatment. Another method is the topical treatment of prickly heat, which involves the use of cooling powders locally, such as prickly heat powder or cooling and itching-relieving washes, such as calamine lotion or menthol tincture. In cases of pustular prickly heat, calamine or berberine powder can be used topically.

Can children eat eggs when they have prickly heat?

When children develop prickly heat, it is best not to feed them eggs. Prickly heat in children primarily occurs because the sweat glands in the skin become blocked, leading to a type of skin disease. When children develop prickly heat, we need to cool and dry their skin, which will improve and relieve the condition. In terms of diet, we should also avoid spicy and irritating foods, greasy foods, and foods that are likely to cause allergies. Eggs, being rich in proteins, can easily trigger allergies. Therefore, when a child has prickly heat, it is best to avoid giving them eggs. If the child's prickly heat is severe, we can also apply topical medications to the affected area. The principle for using medications should be based on cooling, astringent, and anti-itch properties.

The difference between eczema and prickly heat

Eczema and heat rash have clear differences, distinguished by their causes, affected areas, and symptoms. The cause of heat rash is mainly due to blocked sweat pores, typically triggered by hot and humid environmental conditions; eczema, on the other hand, is usually caused by allergic factors such as food allergies, pollen, dust mites, animal fur, etc., and is also related to disorders of gastrointestinal function and indigestion. The seasonal occurrence of the two conditions also differs. Heat rash usually occurs in the summer, while eczema can occur in any season and at any age. The affected areas are also different. Heat rash typically appears on the chest, back, inside the elbows, neck, and forehead, whereas eczema can occur on any part of the body. The clinical manifestations of the two are also different; heat rash involves inflammation of the sweat glands, with the skin turning red and a dense distribution of papules. Eczema, on the other hand, primarily features symmetrically distributed erythema and papules, and may also include exudation.
