While most of us in North Yorkshire welcome summertime and higher temperatures, heat waves can cause health problems, especially for those with existing health issues.
The Met Office website warns about a heat wave when temperatures are likely to be very high for several days in a row. Sometimes, heat waves are accompanied by high humidity.
If you are likely to be at particular risk, or care for people who could be at risk during a heat wave, it's important that you plan ahead. Taking action in advance can help reduce the problems caused by this type of weather.
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 and heatstroke
Tips for hot weather
- look out for those who may struggle to keep themselves cool and hydrated – older people, those with underlying health conditions and those who live alone are particularly at risk
- stay cool indoors – many of us will need to stay safe at home this summer so know how to keep your home cool
- close curtains on rooms that face the sun to keep indoor spaces cooler and remember it may be cooler outdoors than indoors
- 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
- walk in the shade, apply sunscreen regularly and wear a wide brimmed hat, if you have to go out in the heat
- avoid exercising in the hottest parts of the day
- make sure you take water with you, if you are travelling
- if you are going into open water to cool down, take care and follow safety advice

Remember, heatstroke can kill. It can develop very suddenly, and rapidly lead to unconsciousness. If you suspect someone has heatstroke, call 999 immediately.

A heat wave can affect anyone, but the most vulnerable people are:
- older people, especially those over 75

- people who misuse alcohol or drugs
