How to stay safe in hot weather

Stay out of the heat:

  • Keep out of the sun between 11am and 3pm
  • If you have to go out in the heat, walk in the shade, apply sunscreen and wear a hat and light scarf
  • Avoid extreme physical exertion
  • Wear light, loose-fitting cotton clothes

Cool yourself down:

  • Have plenty of cold drinks, and avoid excess alcohol, caffeine and hot drinks
  • Eat cold foods, particularly salads and fruit with a high water content
  • Take a cool shower, bath or body wash
  • Keeping your living space cool is especially important for infants, the elderly or those with chronic health conditions or who can’t look after themselves
  • Place a thermometer in your main living room and bedroom to keep a check on the temperature
  • Keep windows that are exposed to the sun closed during the day, and open windows at night when the temperature has dropped
  • Close curtains that receive morning or afternoon sun, however, care should be taken with metal blinds and dark curtains, as these can absorb heat – consider replacing or putting reflective material in-between them and the window space
  • Turn off non-essential lights and electrical equipment – they generate heat



Look out for others:

  • Keep an eye on isolated, elderly, ill or very young people and make sure they are able to keep cool
  • Ensure that babies, children or elderly people are not left alone in stationary cars
  • Check on elderly or sick neighbours, family or friends every day during a heatwave
  • Be alert and call a doctor or social services if someone is unwell or further help is needed
  • If you have a health problem:
  • Keep medicines below 25 °C or in the refrigerator (read the storage instructions on the packaging)
  • Seek medical advice if you are suffering from a chronic medical condition or taking multiple medications If you or others feel unwell:
  • Try to get help if you feel dizzy, weak, anxious or have intense thirst and headache; move to a cool place as soon as possible and measure your body temperature
  • Drink some water or fruit juice to re-hydrate
  • Rest immediately in a cool place if you have painful muscular spasms (particularly in the legs, arms or abdomen, in many cases after sustained exercise during very hot weather), and drink oral re-hydration solutions containing electrolytes.
    Medical attention is needed if heat cramps last more than one hour
  • Consult your doctor if you feel unusual symptoms or if symptoms persist
