Britain is experiencing a mini-heatwave this week with temperatures reaching above 30C in southern regions. Northern parts of the UK will also see a rapid rise in temperatures between 25-28C, with temperatures are expected to remain above average for the rest of the week.

Commuters in the capital are already suffering the effects of the high temperatures, as London Underground soar in the mini-heatwave. Here are eight ways to keep cool as the temperature rises:

1. Drink plenty of water

It seems obvious but it is safe to say Brits are simply not used to hot weather – and so we are unlikely to change our habits of not drinking enough fluids as the mercury rises. Dehydration is a major risk in a heatwave, so make sure you have a bottle of water with you at all times, particularly if travelling on public transport.

2. Cool your pulse points

Cold compresses on your wrists, neck, the backs of your knees and other pulse points can help cool your body down.

3. Avoid the heat

Stay out of the sun between 11am and 3pm – the hottest part of the day – if you are vulnerable to heat. If you are going outside, make sure you stay in the shade and wear plenty of high-factor suncream.

4. Keep rooms cool

Use shades or reflective material outside the windows to prevent your home heating up like a greenhouse. Beware, however – metallic blinds and dark curtains can make a room hotter, so stick to light-coloured curtains. Turning off electrical items can help keep the temperature down.

5. Eat spicy food

Although it sounds counter-intuitive, eating spicy food, such as curry, can help you keep cool. It contains capsaicin, an active component in chilli peppers, which will help stimulate sweat production and cool you down as it evaporates.

6. Loose clothing

Tight clothing will increase your body temperature and can be extremely uncomfortable in humid heat. Wear loose, cool clothing and put on a hat if you go outside.

7. Stick to cotton

Cotton and linen clothes are best for keeping cool when it's hot, as it is a breathable material that allows sweat to evaporate easily. Cotton bed sheets are ideal for sleeping better in hot weather too.

8. Take a day off from sports

Don't overdo it with strenuous exercise – use the hot weather as an excuse for a day off.

What are the risks posed by a heatwave?

Dehydration – not having enough water

Overheating

Heat exhaustion

Heatstroke

The sick or elderly are particularly vulnerable to high temperatures. Public Health England advises to check up on those who may be susceptible to heat-related problems.

What are the symptoms of heatstroke or dehydration?

The signs of heatstroke or heat exhaustion include: hot skin that feels flushed, dizziness, extreme fatigue, nausea, vomiting, a rapid heartbeat, confusion and much darker urine than normal.
