Miliaria is usually self-limiting, meaning it generally subsides and heals on its own without specific treatment as environmental conditions improve, such as with lower temperatures, reduced humidity, and decreased sweating. The time required for spontaneous recovery may vary among individuals. If the symptoms of miliaria are severe or accompanied by skin infection, recovery may take longer. In addition, to accelerate the resolution of miliaria and relieve discomfort, some supportive measures can be taken, such as keeping the skin clean and dry, wearing loose and breathable clothing, and using appropriate cooling and anti-itch medications. Therefore, although most cases of miliaria resolve spontaneously, observation and management should be based on the specific circumstances.
