Heat exhaustion
Headache, dizziness, nausea, heavy sweating, thirst, cramps, or weakness can be warning signs.
Move somewhere cool, remove extra clothing, cool the skin, and give fluids if the person can drink.

Heat safety
Know when heat is more than uncomfortable.
This site cannot diagnose you. Check on older people, young children, people with long-term conditions, and anyone who lives alone.
Medical emergency
Possible heatstroke
Confusion, loss of coordination, seizure, loss of consciousness, very high temperature, hot skin that may not be sweating, or severe breathing difficulty need urgent help.
Call emergency services now. Cool the person while waiting and follow the call handler’s instructions.
Long term
Make the next hot day easier.
Shade the glass first
External shutters, awnings, or shade are strongest. Curtains and blinds still help, especially when closed early.
Improve night ventilation
Create a safe route for air across the home. Secure window restrictors may help where appropriate.
Choose the right fan
A simple, quiet fan can improve comfort. Use it across people or to support cooler outdoor airflow.
Consider active cooling
For repeated severe overheating, get advice on an efficient heat pump or air conditioner sized for the space.
