Older people urged to take action between 11am and 3pm

Temperatures have soared past 30 degrees during the fourth heatwave of the summer. Scorching conditions pose numerous health risks, with a yellow warning already issued for parts of Britain until Monday, though certain groups face greater danger than others.

Age UK charity director Caroline Abrahams cautioned that elderly people must exercise additional care during sweltering weather, particularly those with underlying medical conditions, as they're more vulnerable to heat's impact. She explained: "Older people do need to take extra care though as temperatures rise, especially if they have long term health conditions impacting their heart, lungs or kidneys.

"It can exacerbate certain medical problems, and some medications make us more susceptible to hot weather. Generally, our bodies find it harder to adapt to more extreme temperatures as we age."

She advised pensioners to remain indoors between 11am and 3pm. This typically represents the day's most blistering period, making it wise to dodge the sun and avoid activities like strolling, shopping or gardening during these hours.

Escaping blistering heat may seem impossible when it steadily transforms your house into an oven, particularly since British homes are typically designed for chilly rather than sweltering conditions. However, several methods can help maintain your property as a refreshing refuge.

Caroline said: "Most of our homes aren't really designed to cope with scorching weather, so it's a good idea to do all we can to keep the cool air in and hot air out. We can keep windows open at night, but it's best to keep both windows and curtains closed during the day."

If you are venturing outdoors, straightforward adjustments like taking water with you and ensuring you remain hydrated can prove crucial during the most sweltering conditions. Donning pale-coloured garments can also reduce the impact of the heat and sun.

Regular application of sun cream is also essential when outdoors, and monitoring the weather forecast and UV levels can help determine when to reapply or seek shelter in the shade. Age UK also suggested people who wear spectacles speak to their optician about prescription sunglasses.

However, it is not only elderly people that the specialist is urging to take additional precautions during the hot spell. She explained: "We can also all help keep older people safe during episodes of severe heat by checking in on older relatives, friends, and neighbours to see if they need anything and to make sure they are not feeling overwhelmed by the excessive heat. You could offer help to get shopping or picking up any medication, or you may even have an extra fan you could lend."

Dehydration poses a significant risk for elderly people and those with particular medical conditions during a heatwave. This can trigger muscle cramps, confusion, feelings of exhaustion and sleep difficulties. It's crucial to remember that you may not always feel thirsty even if you're dehydrated.

Age UK advises that if you suspect you or someone else is suffering from dehydration, it's best to rest in a cool, dark place and drink plenty of fluids. If symptoms persist, don't hesitate to dial 111 for advice.

Heat exhaustion is another risk, particularly for vulnerable people during periods of intense heat. Symptoms can include headaches, dizziness, nausea, weakness, excessive sweating and a rapid heartbeat.

If left untreated, heat exhaustion can escalate into heatstroke, which can lead to confusion, disorientation, seizures and even loss of consciousness. This is a potentially fatal condition, so if these symptoms are present, immediately call 999 or activate a community alarm.
