People in vulnerable groups may get symptoms like feeling tired, a headache and having trouble concentrating. They are also at greater risk of more serious health problems, like dehydration and heat stroke. That is why it is important to look after each other. This page lists more symptoms that can be caused by heat.
When it has been hotter than 30 °C for several days, anyone can get symptoms due to heat. This is because your body uses up energy to cool itself. Coping with heat is like taking part in vigorous exercise. This is especially true when the heat continues for several days in a row. The following symptoms are common:
- discomfort
- feeling tired
- difficulty concentrating
- a headache
- dizziness
- muscle ache
- thirst
- trouble sleeping
- excessive sweating
In serious cases, dehydration can lead to:
- cramps
- nausea
- exhaustion
- fainting
- unconsciousness
Look after each other
Informal carers, but also anyone else who takes care of another person, can help prevent discomfort and health problems. Actions that can help another person are often simple, but can make a world of difference.
- Make sure the person gets enough to drink. Leave a pitcher within easy reach or refill their glass often.
- Help them think about the best time of day to be active. For example, this might be in the morning or at the end of the day, when the temperature is lowest.
- Close the curtains or turn on a fan to keep the house (and everyone in it) cool.
