The human body is generally very good at managing its own temperature. We shiver when we’re too cold and sweat when we’re too hot.In general, our body does a fantastic job at taking care of us in a range of climates. However, this regulator isn’t foolproof, and if we’re not careful in difficult conditions, heat stress can occur. Here’s our full heat stress guide to keep you, and your employees, safe as the temperature rises.
When your body feels the temperature rising, it increases blood flow to the skin’s surface, carrying the heat in your body up towards your skin. This causes us to sweat and as the sweat evaporates, we start to cool down. It’s not just sweat that helps to lower the body’s temperature. If our skin temperature is warmer than outside (which is often the case in cooler climates), then we will be able to lose heat externally without sweating. However, if the outside temperature is too hot, the body relies solely on sweating to cool itself down.
