Severe heatwaves are relatively uncommon in Wales. However, the experience across Northwest Europe in 2003 when 27,000 people died as a direct cause of the heatwave that year, is a reminder that heat can be fatal. In case of a heatwave, make sure you look after your own health and that of your family. It is not just children who need special attention; be aware that elderly people are also at risk, and make sure they are being checked on.

Keep out of the heat

  • If a heatwave is forecast, try and plan your day in a way that allows you to stay out of the heat;
  • Avoid alcohol as it can cause dehydration;
  • If you can’t avoid strenuous outdoor activity, like sport, DIY, or gardening, keep it for cooler parts of the day, like early morning;
  • If you must go out, stay in the shade. Wear a hat and light, loose-fitting clothes, preferably cotton. If you’ll be outside for some time, take plenty of water with you.

Stay cool

  • Stay inside, in the coolest rooms in your home, as much as possible;
  • Close the curtains in rooms that get a lot of sun;
  • Keep windows closed while the room is cooler than it is outside;
    Open them when the temperature inside rises, and at night for ventilation. If you are worried about security, at least open windows on the first floor and above;
  • Take cool showers or baths, and splash yourself several times a day with cold water, particularly your face and the back of your neck.

Drink regularly

  • Drink regularly even if you do not feel thirsty – water and fruit juice are best;
  • Avoid tea, coffee and alcohol as they can cause dehydration;
  • Eat as you normally would. Try to eat more cold food, particularly salads and fruit, which contain water.

Seek advice

  • Contact your doctor, a pharmacist or NHS Direct (0845 4647) if you’re worried about your health during a heatwave, especially if you are taking medication, or have any unusual symptoms;
  • Look after yourself and others, especially those at greater risk such as elderly people and children: symptoms of heat exhaustion include headaches, dizziness, nausea and vomiting, muscle weakness or cramps, pale skin and a high temperature. If you or someone you know experiences a sudden rise in temperature, confusion or loss of consciousness, heat stroke may have developed;
  • If you have these symptoms, rest for several hours, keep cool and drink water or fruit juice. Seek medical advice if you get worse or the symptoms don’t go away.
