Keeping cool in the heat

[00:00.40] This summer, the UK, and much of the northern hemisphere, has experienced a heatwave – a sustained period of roasting temperatures and scorching sunshine.

[00:12.35] While many welcome the Sun and warmth, too much can be dangerous to health. So what are the best ways to keep cool?

[00:22.44] Firstly, avoiding exposure is a good idea, says the UK Met office.

[00:28.29] This means not going out in direct sunlight, or, where possible, sticking to shadows and shade.

[00:35.46] This also means that covering up is a good idea.

[00:39.18] Wear loose, airy clothing, which fully covers the body, as well as a hat and sunglasses.

[00:46.08] In addition, a parasol could provide valuable protection.

[00:50.86] Finally, the UK's National Health Service recommends not going out between 11 in the morning and three in the afternoon if you are vulnerable to the Sun.

[01:02.82] Staying hydrated is another excellent idea.

[01:06.27] The human body is approximately 60% water, which on a hot day, can be depleted through sweat.

[01:13.71] If this water is not replenished, dehydration can occur.

[01:17.69] The US Geological Survey's water science school recommends drinking three litres a day for an adult male, and 2.3 litres for an adult female, though this varies according to circumstance.

[01:30.44] You should also avoid alcohol, which dehydrates the body.

[01:36.02] Whether at home or at work, steps should be taken to reduce temperatures indoors, too.

[01:42.39] Blinds, curtains and shades should be closed and windows opened to allow the building to ventilate.

[01:50.10] This is especially important at night while you sleep.

[01:53.82] The UK Met office says "night cooling is important as it allows the body to recuperate."

[02:00.99] Finally, for those working outside, extra precautions should be taken.

[02:07.10] In addition to staying covered and drinking water, high-factor sunscreen should be worn to stop sunburn and the possible development of skin cancer.

[02:16.66] In addition, those who perform physical tasks in the Sun should be careful of heatstroke, which, according to the UK Met Office, can be fatal.

[02:28.08] For many, summer is a well-loved period of warmth and outdoor activity, but as the old saying goes, everything in moderation.

[02:38.18] That said, as long as people remember the basics and look after themselves, there is no reason why a prolonged heatwave can't become the summer that everyone remembers.
