Stay out of the heat
Try to stay indoors, especially between midday and 3pm.
Avoid outdoor activities such as sport, DIY or gardening. If this is not possible, do it first thing in the morning or late in the evening.
Use sunscreens or sun blocks to help prevent sunburn.
Cover up with a long sleeved top or other loose-fitting clothes.
Wear a hat to shade your head and sunglasses to protect your eyes.
Drink plenty of water, at least eight glasses a day. Avoid alcohol, tea or coffee as they can dehydrate you.
Take a cool bath or shower, or splash your face with cold water to cool down.
Keep your home cool
Turn off non-essential lights and electrical equipment - they generate heat.
Keep indoor plants and bowls of water in the house - evaporation helps cool the air.
If possible, move into a cooler room, especially for sleeping.
Electric fans may help, but only use if necessary.
Stay in the coolest rooms as much as possible.
Keep rooms shaded and cool by closing blinds and curtains. Keep windows closed until after the sun has set.
Look out for others
Keep an eye on young and older people and people who are ill or on their own. Check in on family, friends and neighbours.
Make sure that babies, children or elderly people are not left alone in parked cars.
Call a doctor or social services if help is needed.
If you have a health problem
Keep medicines below 25°C or in the fridge (check the instructions on the packet).
Chat with your GP or pharmacist if you have a long term health problem or take multiple medications.
If you or others feel unwell
Try to get help if you feel dizzy, weak, anxious, have a headache or are really thirsty.
Move to a cool place to rest.
Drink some water or fruit juice.
Rest immediately in a cool place if you have painful muscle spasms (particularly in the legs, arms or stomach, and have a cool drink.
Drinks that help you to feel better after having diarrhoea (drinks that contain electrolytes), can also help if you have heat stroke.
Get medical help if heat cramps last more than one hour.
