THE top ways to stay safe when the heat arrives, according to the Met Office.

• Look out for those who may struggle to keep themselves cool and hydrated such as the elderly with underlying conditions or live alone.
• If you live alone, ask a relative or friend to phone to check that you are not having difficulties during periods of extreme heat.
• Stay cool indoors – Close curtains on rooms that face the sun to keep indoor spaces cooler and remember it may be cooler outdoors than indoors.
• If going outdoors, use cool spaces considerately. 
• Drink plenty of fluids and avoid excess alcohol. 
• Never leave anyone in a closed, parked vehicle, especially infants, young children or animals.
• Try to keep out of the sun between 11am to 3pm, when the UV rays are strongest.
• Walk in the shade, apply sunscreen and wear a wide-brimmed hat, if you have to go out in the heat.
• Avoid physical exertion in the hottest parts of the day.
• Make sure you take water with you, if you are travelling.
• Check the latest weather forecast and temperature warnings – you can find these on TV, radio, mobile app or website.
• During warm weather going for a swim can provide much welcomed relief. If you are going into open water to cool down, take care and follow local safety advice.
