Dry heat refers to a type of heat that lacks moisture in the air. It is commonly experienced in arid climates, where the humidity levels are low. This kind of heat can lead to rapid evaporation of sweat from the skin, making it feel hotter than it actually is. In dry heat conditions, the body may struggle to cool itself effectively, which can lead to dehydration. People often need to drink more water to stay hydrated and avoid heat-related illnesses. Activities in dry heat should be approached with caution, especially during peak temperatures.
