Beat the heat: Top tips for staying cool on a hot day

Recently we’ve been asked by consumers for our tips on staying cool in hot weather. The UK summers are getting hotter, so what are our options?

Of course, if you can afford it, a portable air conditioner is the fastest cooling option, but they’re pricey and can be noisy. Fans are cheaper and quieter, but while you can buy some great fans for airflow and energy efficiency these days, on a very hot day they often just circulate the hot air.

Sometimes the simplest of tips can help:

• Keep curtains shut during the day, and open windows at night.
• Try putting a bowl of ice in front of your fan to get cold air circulating – respect electricity though, make sure it's not too close to the appliance.
• Stay hydrated and drink plenty of cool fluids. Avoid alcohol as it messes with your temperature regulation.
• Wear loose, light coloured clothes of natural, breathable fibres like cotton or linen.
• Try not to eat too heavily or too close to bedtime – it's best not to eat two or three hours before you head to bed.
• In the office and at home, switch off any tech that isn’t being used (such as monitors and chargers) as these can give off a surprising amount of heat.
• At home, try not to use heat-generating appliances like ovens and irons.
• Take a dip in the sea – we’re surrounded by it, so why not get the benefit.
• Once the sun has gone down, open windows at either side of the room to help the air draw through. If you only have one window you can use a fan at the opposite side of the room from the window to create the same affect.
• At night, use cotton sheets on your bed – polyester traps the heat. You may also want to ditch your duvet.
• If you're especially hot at night, put a cotton sheet in a bag and put it in the freezer. Take it out before bed and use this instead of your duvet.
• Have a cool shower to help bring your temperature down or put a cold flannel on your forehead. 
• Drink cool water before bed and keep a glass on your bedside table.

Watch out for heat exhaustion

Heat exhaustion can creep up on you. Watch out for a headache, dizziness, feeling sick or confused, clammy skin, muscle cramps, and a racing heartbeat. You’ll likely be sweating but your skin might still feel cold or pale.

It’s not usually an emergency if you act fast: lie down somewhere cool, with your legs slightly raised, sip water or an isotonic sports drink, and get someone to keep an eye on you.

If you’re not better in 30 minutes, call your GP or ring 999 — don’t wait.
