15 Common Causes of Heat Intolerance You Shouldn’t Ignore

Infections and Illnesses

Infections and illnesses can cause heat intolerance. The most common diseases that cause heat intolerance include the flu (influenza), pneumonia, and infectious diarrhea.

Heat intolerance is not a normal part of any infection or illness, so if a person has an infection and is experiencing symptoms like sweating, dizziness, or weakness when in the heat, it’s essential to see a doctor immediately. 

Once they have been diagnosed with an infection or illness that causes heat intolerance, they’ll be able to prescribe medications to help treat the symptoms while allowing them to stay safe in hot weather conditions.
