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.

Do children get itchy from heat rash?

It itches. Miliaria, caused by blocked sweat ducts, commonly occurs in newborns due to their underdeveloped sweat ducts, as well as in hot environments and situations like prolonged bedrest, which can easily lead to the condition. Some skin infections that block sweat ducts can also cause miliaria. Miliaria is classified into types such as clear miliaria, red miliaria, pustular miliaria, and deep miliaria. Red miliaria is characterized by a burning and itching sensation. In areas with pustular miliaria lesions, there is also a burning, itching, and painful sensation, while the symptoms in areas affected by clear and deep miliaria are less noticeable.

The difference between prickly heat and chickenpox

Prickly heat is a physical skin condition that often occurs in hot and humid summer weather, related to excessive sweating, especially common among infants, the elderly, and people working in high-temperature environments. It appears in three types: white, pustular, and red prickly heat. Generally, prickly heat does not have systemic symptoms; it does not feature fever and is not contagious. Chickenpox, on the other hand, is a common acute infectious skin disease, mainly characterized by scattered erythema and vesicles on the trunk, face, and proximal limbs. It is contagious and has prodromal symptoms such as fever, fatigue, and muscle soreness.
