Health leaders across Devon and Cornwall are asking people to take a bit of extra care during the current hot spell, especially those living with long-term health conditions.
A Heat-Health Alert has been issued for the next five days by the UK Health Security Agency (UKHSA) and the Met Office, highlighting the risks that higher temperatures can bring to people’s health.
Hot weather can put extra pressure on the body. It can lead to dehydration, overheating, and make existing health issues worse. People with conditions like heart or lung disease, diabetes, kidney problems or mental health conditions may be more affected.
Some medications and having more than one condition can also make it harder for the body to stay cool and properly hydrated.
Here are some simple steps to stay well:
Try to stay out of the heat, particularly between 11am and 3pm
Drink plenty of fluids regularly
Keep your home cool by closing blinds or curtains during the day
Avoid strenuous activity in the hottest part of the day
Check in on friends, family and neighbours, especially older people or those living alone
Store medicines correctly and take them as prescribed
If you’re living with a long-term condition, it’s especially important to:
Keep an eye on your symptoms and seek advice if they get worse
Make sure you have enough medication and understand how heat might affect it
Stay cool and hydrated to reduce strain on your body
People with heart, lung or kidney conditions may be particularly vulnerable to dehydration and heat-related illness. Those with diabetes should monitor their blood glucose levels carefully, as hot weather can affect blood sugar control and insulin storage.
People living with dementia may be less aware of the effects of heat or forget to drink enough fluids, so carers and family members are encouraged to provide regular support and reminders.
You can contact NHS 111 for urgent advice, or 999 in an emergency.
Some people are more vulnerable in hot weather, including:
People aged 65 and over
Babies and young children
People with long-term health conditions
Those on multiple medications or living alone
Dr Chris Reid, Chief Transformation and Place Officer at NHS Cornwall and Isles of Scilly said: “While many people enjoy the warmer weather, it can be more challenging for those with underlying health conditions. We’re asking everyone to take a few simple steps to stay well and to check in on those who might need a little extra support during this time.”
