How to stay cool in a heatwave: Met Office offers their tips on staying safe during hot weather

The UK is sweltering in record-breaking temperatures, just days after the Summer Solstice. But while for some the hot weather is welcome, when temperatures remain high for several days, it can pose risks to health and wellbeing.

While anyone can be affected by the effects of prolonged heat, some are more vulnerable, including older adults, those with underlying health conditions, and those exposed to heat through their work or living environment.

"Prolonged heat can lead to dehydration, overheating, and in more serious cases, heat exhaustion or heatstroke," the Met Office said. "These conditions can develop quickly, particularly during periods of strong sunshine and high humidity, and it is important to recognise the risks early and take action to stay cool."

In a bid to help people tackle the imposing heat of some 40C conditions, the Met Office has issued some simple advice, including when you are indoors, in the sun and how to spot heat-related illness.

Staying cool indoors

"Keeping your home cool is one of the most effective ways to manage high temperatures," the Met Office spokesperson said. "Closing curtains or blinds in rooms that face the sun can help prevent heat from building up indoors. While it may seem counterintuitive, keeping windows and doors closed during the hottest part of the day can help retain cooler air inside."

They said windows could then be opened once temperatures begin to fall later in the day, helping ventilate your home with cooler air.

Staying hydrated and avoiding heat stress

"Drinking plenty of fluids is essential in hot weather," the spokesperson went on. "Water is the best option, and it is important to drink regularly even if you do not feel thirsty. Reducing alcohol intake can also help prevent dehydration.

"It is best to avoid strenuous activity during the hottest part of the day. If you need to be active outdoors, try to plan this for the early morning or later in the evening when temperatures are lower. Carrying water with you, particularly when travelling, is also important, as journeys can sometimes take longer than expected."

Keeping safe in the sun

With the sun strongest between late morning and mid-afternoon, the Met Office advised limiting time outdoors during those peak hours. "If you do need to go outside, staying in the shade, wearing a hat, and applying sunscreen can help protect against the sun’s intensity," the spokesperson said.

"UV levels can be high during hot spells, increasing the risk of sunburn, so taking precautions is essential even on days with light cloud."

Supporting vulnerable people

People are being encouraged to check on neighbours, including those who may find it difficult to adapt their routines. "Checking in on friends, family members, or neighbours who may be vulnerable can make a significant difference," the spokesperson added.

"Ensuring they have access to water and a cool environment is particularly important. It is also essential never to leave anyone in a closed, parked vehicle, especially children or pets, as temperatures can rise rapidly to dangerous levels."

Recognising heat-related illness

Key signs of heat-related illness include feeling unwell with a high temperature, dizziness, or unusual fatigue during hot weather may indicate heat exhaustion or heatstroke. "Acting quickly by moving to a cooler place, hydrating, and seeking medical advice if needed can help prevent more serious complications," the Met Office advised.

Keeping pets safe in a heatwave

"Pets are also vulnerable to hot weather and need extra care," they went on. "Ensure they always have access to fresh water, shade, and a well-ventilated space. Walking dogs should be avoided during the hottest part of the day, with early morning or late evening being safer times.

"Checking ground surfaces before walking pets is also important, as pavements can become extremely hot and cause injury. Providing cool areas and avoiding overexertion will help keep animals comfortable during periods of heat."
