Be prepared for hot weather
Bright, hot summer days are what many of us look forward to for the rest of the year – especially in England!
However, while we’re enjoying the balmy days of summer, we should not forget that the temperature can get too high, that it can become uncomfortably hot, and for some, it can become dangerously hot.
The evidence about the risks to health from heatwaves is extensive and consistent from around the world. Excessive exposure to high temperatures can kill.
Those that are most at risk due to hot weather include:
- older people, especially those over 75
- babies and young children
- people with a serious chronic condition, especially heart or breathing problems
- people with mobility problems, for example people with Parkinson’s disease or who have had a stroke
- people with serious mental health problems
- people on certain medications, including those that affect sweating and temperature control
- people who misuse alcohol or drugs
- people who are physically active, for example labourers or those doing sports
Stay out of the heat
- Keep out of the sun between 11.00am and 3.00pm.
- 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.
- Sprinkle water over the skin or clothing, or keep a damp cloth on the back of your neck.
Keep your environment cool
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.
- Keep indoor plants and bowls of water in the house as evaporation helps cool the air.
- If possible, move into a cooler room, especially for sleeping.
- Electric fans may provide some relief, if temperatures are below 35°C.
- Consider putting up external shading outside windows.
- Use pale, reflective external paints.
- Have your loft and cavity walls insulated – this keeps the heat in when it is cold and out when it is hot.
- Grow trees and leafy plants near windows to act as natural air-conditioners.
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 rehydrate.
- 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 rehydration 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.
