Tropical Climates:
The people who are already living in tropical regions are more likely to get heat rashes as compared to the people who live in other regions in the world. Due to the hot and humid weather in the tropical region can cause more heat rashes and can further trigger the already present rashes on the skin. Tropical weather with its hot climate can worsen the condition of heat rashes by causing more inflammation in the skin and increasing the number of tiny red bumps on the skin.
