睡前必背10句英文口语（BBC随身英语Keepingcool）

This summer, the UK, and much of the northern hemisphere, has experienced a heatwave – a sustained period of roasting temperatures and scorching sunshine. While many welcome the Sun and warmth, too much can be dangerous to health. So what are the best ways to keep cool ?

Firstly, avoiding exposure is a good idea, says the UK Met office. This means not going out in direct sunlight , or, where possible, sticking to shadows and shade . This also means that covering up is a good idea. Wear loose, airy clothing, which fully covers the body, as well as a hat and sunglasses. In addition, a parasol could provide valuable protection. 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.

Staying hydrated is another excellent idea. The human body is approximately 60% water, which on a hot day, can be depleted through sweat . If this water is not replenished, dehydration can occur. 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. You should also avoid alcohol, which dehydrates the body.

Whether at home or at work, steps should be taken to reduce temperatures indoors, too. Blinds , curtains and shades should be closed and windows opened to allow the building to ventilate . This is especially important at night while you sleep. The UK Met office says "night cooling is important as it allows the body to recuperate."

Finally, for those working outside, extra precautions should be taken. In addition to staying covered and drinking water, high-factor sunscreen should be worn to stop sunburn and the possible development of skin cancer. 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.

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