Heat-related Conditions

The following conditions can arise when the body is exposed to high temperatures and humidity in both outdoor and indoor environments. All heat-related stress incidents and illnesses can be prevented.

Heat Rash: Individuals working in high-heat and humidity environments are at risk for heat rash. Blocked sweat ducts trap sweat beneath the skin, blocking pores that create the heat rash. Symptoms vary from red, welt-like lumps to blisters. The skin may feel itchy, or it can have a tingling or prickly sensation.

Heat Cramps: Workers performing strenuous activities in hot, humid environments lose fluids and electrolytes at a rapid pace. This can result in painful, long-lasting muscle spasms or cramps. Symptoms include involuntary spasms or cramping in the following muscle groups:

• Back
• Abdomen
• Calves
• Arms
