Many people enjoy warm weather, but heatwaves can cause heat exhaustion and heatstroke in the elderly, young children, and other vulnerable groups.
Who is most at risk?
Heatwaves can affect any of us, but those most at risk include:
- babies and young children
- people over 65
- people with underlying health conditions including problems with breathing, heart, kidneys and diabetes
- people with Alzheimer’s and dementia
- people who spend a lot of time outside or in hot places (such as those who work outdoors or the homeless)
Tips for keeping cool in hot weather
When inside you should:
- turn off lights and appliances not in use as they generate heat
- close windows that face the sun during the day, and open them at night when the temperature drops
- close curtains in rooms that get morning or afternoon sun
- sprinkle water over your skin, or keep a damp cloth on the back of your neck
- use an electric fan (but only if the temperature is below 35 degrees)
When outside you should:
- avoid going out during the hottest part of the day if possible (11am to 3pm)
- wear light and loose-fitting clothing that covers your skin
- wear a wide brimmed hat and sunglasses
- regularly apply a broad-spectrum (UVA and UVB) water-resistant sunscreen to skin that is not covered, using factor 30+ for adults and 50+ for children
- stay in the shade
Drink plenty of fluids
- Adults need about 2 litres of water over 24 hours (may be less for smaller people or those with medical conditions)
- Drink more fluids when you feel any dehydration symptoms. The best fluids to drink are water or oral rehydration sachets (ask your pharmacist about how to use these safely)
- Drink enough during the day so your urine (pee) is a pale clear colour
Helping a person under your care drink enough
A person you're caring for may not have a sense of how much they're drinking.
You can help them by:
- making sure they drink during mealtimes
- make drinking a social thing, like 'having a cup of tea'
- offer food with a high water content such as ice cream, jelly, fruits like melon
Health advice for health and care professionals
Service providers with a duty of care to their clients, as well as those working with vulnerable groups, need to be aware of the effects and increased demands that come with a heatwave.

When to get medical help
Heat exhaustion and heatstroke
Heat exhaustion is not usually serious if you can cool down within 30 minutes. If it turns into heatstroke, it needs to be treated as an emergency.

Dehydration
Dehydration means that your body does not have enough fluid. If it's not treated, it can become a serious problem.
