Understanding Heat Exhaustion
Heat exhaustion is a heat-related illness that can occur after you've been exposed to high temperatures, and it often is accompanied by dehydration. Recognising the signs of heat exhaustion is crucial, especially during the warmer months or while engaging in outdoor activities. This knowledge is particularly relevant in the UK, where people might not be as accustomed to high heat.
Common Signs of Heat Exhaustion
Heat exhaustion manifests through a variety of symptoms that signal the body is struggling to regulate its temperature. These symptoms can develop rapidly or over the span of several days, especially when engaging in physical activities under hot weather conditions.
Heavy Sweating: One of the first and most obvious signs is excessive sweating. This is the body's effort to cool down but, in excessive heat, it might not be sufficient.
Weakness or Fatigue: Feelings of extreme tiredness or exhaustion even after minimal activity could indicate that the body is under duress from heat exposure.
Dizziness and Headaches: The heat often affects the brain's ability to function properly, leading to dizziness, headaches, or lightheadedness.
Cool, Moist Skin: Despite the outside heat, the skin might feel cool and moist due to heavy sweating.
Nausea or Vomiting: An upset stomach or vomiting can be a warning sign, especially if accompanied by other symptoms.
Weak, Rapid Pulse: The heart rate may increase as the body attempts to cool itself, resulting in a fast but feeble pulse.
Additional Warning Signs
Beyond the immediate signs, there are other symptoms that might also indicate heat exhaustion:
Muscle Cramps: Painful cramps, especially in the legs or abdomen, can occur when the body's salt levels drop due to excessive sweating.
Pale or Flushed Skin: Changes in skin color may occur, which are often noticeable and signal distress.
Shallow Breathing: Some people may experience rapid yet shallow breathing.
Confusion or Irritability: Mental symptoms like confusion or sudden irritability could suggest heat-related stress on the body.
Treatment and Prevention
Recognising these symptoms early is essential to prevent progression to heat stroke, a more severe condition. If you or someone you know experiences these symptoms, it's important to move to a cooler place, drink fluids, and rest. Avoiding strenuous activity during peak heat hours and wearing appropriate clothing can also help prevent heat exhaustion.
In the UK, as heatwaves become more frequent due to climate change, awareness and prevention of heat exhaustion are increasingly important. Understanding and recognising these signs can make a significant difference in maintaining health and safety during hot weather.

Heat exhaustion happens when you get too hot. It can make you sick, especially if you don't drink enough water. This is important to know when it's sunny outside or if you are playing outside. In the UK, we are not used to very hot weather, so we need to be careful.
How to Tell if Someone Has Heat Exhaustion
There are signs that show when someone is too hot. These can happen quickly or over a few days, especially if they are playing or working outside in the sun.
A Lot of Sweating: Sweating helps cool the body. But if it is very hot, sweating might not be enough.

Fast Weak Pulse: Your heart might beat fast but feel weak as it tries to cool the body down.
More Signs to Watch For
Other signs can also mean someone is too hot:

Skin Looks Pale or Red: Skin color might change when you are too hot.
Quick Shallow Breathing: Some people might breathe fast but lightly.
