Staying safe during the hot weather

As temperatures continue to rise, you should take extra care to protect your health and the health of those around you.

The top ways for keeping safe in the heat include:

• Look out for those who may struggle to keep themselves cool and hydrated. Older people, those with underlying conditions, and those who live alone are particularly at risk of becoming unwell during a heatwave. If you have an elderly neighbour who lives on their own, consider checking in on them
• While it is hot, drink plenty of water and fluids, and avoid going out in the sun and drinking excess alcohol. Drinking water and staying out of the sun are most important for staying well
• Close curtains in rooms that face the sun to keep indoor spaces cooler and remember, it may be cooler outdoors than indoors
• Use cool spaces if going outdoors, like parks with plenty of trees. Find out about more cool spaces available in London
• Never leave anyone in a closed, parked vehicle, especially infants, young children, vulnerable adults, or animals
• Try to keep out of the sun between 11am to 3pm, when the UV rays are strongest
• If you have to go outside in the heat, walk in the shade, apply sunscreen, and wear a wide-brimmed hat
• Avoid physical exertion during the hottest parts of the day
• Make sure you take water with you if you are travelling
• While swimming can be a nice way to cool off, do not be tempted to jump into the River Thames

Look out for signs of heat-related harm:

• If you feel dizzy, weak or have intense thirst and a headache, move to a cool place as soon as possible. Drink some water or diluted fruit juice to rehydrate
• If you have painful muscular spasms (particularly in the legs, arms, or abdomen), rest immediately in a cool place and drink electrolyte drinks. Most people should start to recover within 30 minutes and if not, you should seek medical help

If you, or your child has asthma or other respiratory conditions:

• Keep taking your regular medication and remember to always take your preventer inhaler with you when you’re out and about, due to current high pollen and pollution, combined with extreme heat
• Stay indoors wherever possible, keeping windows and doors closed as much as possible
• If you do need to go outside, shower and change your clothes to wash pollen off
