Tips on how to keep cool during a heat wave


Tips on how to keep cool during a heat wave

Most of us welcome hot weather, but when it’s too hot for too long there are health risks.

With a heat wave set to hit the UK this week, we look at how a heat wave can affect us and offer some advice on how to keep cool.

Why is a heat wave a problem?

The main risks posed by a heat wave are:

  • Dehydration (not having enough water)
  • Overheating, which can make symptoms worse for people who already have problems with their heart or breathing
  • Heat Exhaustion
  • Heatstroke

Who is most at risk?

A heat wave can affect anyone, but the most vulnerable people in extreme heat are:

  • 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 are physically active – for example, labourers or those doing sports

 

Best ways to keep babies and small children cool and hydrated

Babies can become distressed in heat as they have less ability to regulate their body temperature.

  • Breastfed babies may need extra breastfeeds during hot weather. There is usually no need to offer water as your breast milk will adjust. Make sure you drink plenty of water yourself.
  • Bottle-fed babies may need extra formula or small drinks of cool boiled water.
  • Toddlers should be offered water throughout the day
  • A tepid or lukewarm bath may settle and cool down your baby
  • Set babies and young children up in the coolest room of the house with a fan going. The fan should not be pointed directly at them but used to circulate air.
  • Dress your baby lightly while indoors – a vest and nappy is fine.
  • If your house is very hot you can try putting a wet towel in front of the fan so that it cools the air – just keep checking your baby to make sure she is not too cold.
  • Cover your child’s arms and legs if in the sun to avoid sunburn.

 

How to keep cool in the hot weather

The following advice applies to everybody when it comes to keeping cool and comfortable and reducing health risks:

  • Shut windows and pull down the shades when it is hotter outside. If it’s safe, open them for ventilation when it is cooler.
  • Avoid the heat: stay out of the sun and don’t go out between 11am and 3pm (the hottest part of the day) if you’re vulnerable to the effects of heat.
  • Keep rooms cool by using shades or reflective material outside the windows. If this isn’t possible, use light-coloured curtains and keep them closed (metallic blinds and dark curtains can make the room hotter).
  • Have cool baths or showers, and splash yourself with cool water.
  • Drink cold drinks regularly, such as water and fruit juice. Avoid tea, coffee and alcohol.
  • Stay tuned to the weather forecast on the radio or TV.
  • Plan ahead to make sure you have enough supplies, such as food, water and any medications you need.
  • Identify the coolest room in the house so you know where to go to keep cool.
  • Wear loose, cool clothing and a hat if you go outdoors.
  • Check up on friends, relatives and neighbours who may be less able to look after themselves.
