Sweat Rash

Sweat rash, also known as prickly heat or miliaria, is a common skin condition that occurs when the skin's sweat glands become blocked and inflamed.

Causes

• Overheating and excessive sweating
• Clogged pores due to tight clothing or heavy lotions
• Bacterial or fungal infections
• Immobilization or bed rest, leading to increased sweat production
• Certain medications, such as steroids and antibiotics

Symptoms

• Small, red bumps or blisters on the skin
• Itching, stinging, or prickling sensation
• Rash or patches of inflamed skin
• Increased sweating in affected areas

Types of Sweat Rash

• Miliaria crystallina: a mild form characterized by small, clear bumps
• Miliaria rubra: a more severe form with red, inflamed bumps
• Miliaria profunda: a deeper and more severe form with larger, flesh-colored bumps

Treatment and Prevention

• Keeping the skin cool and dry
• Wearing loose, breathable clothing
• Avoiding heavy lotions or creams that can clog pores
• Using gentle, fragrance-free cleansers
• Applying calamine lotion or hydrocortisone cream to reduce itching and inflammation

Complications

• Bacterial or fungal infections if left untreated
• Increased risk of heat exhaustion or heat stroke in severe cases
