Households across the UK are being urged to turn off televisions, laptops, and chargers on Thursday as temperatures are expected to reach up to 35°C, according to health experts. The advice comes as a simple measure to help keep indoor temperatures down during the hot weather.
Why Switching Off Devices Helps
Electrical devices that are not in use still generate heat when plugged in or left on standby. This extra heat can make already warm rooms feel even hotter, according to experts. By switching off non-essential items such as TVs, laptops, games consoles, and chargers, households can reduce the amount of heat being produced inside their homes.
Met Office Warns of More Frequent Heatwaves
The Met Office has stated that there is a greater chance of hotter-than-average conditions this summer, with heatwaves becoming more likely across the UK. The long-term warming trend means heatwaves are expected to become more frequent, longer-lasting, and more intense in the years ahead, making it increasingly important for households to take simple steps to stay safe during spells of hot weather.
Health Risks of High Temperatures
While many people look forward to sunny weather, high temperatures can pose serious health risks. Heat affects the body's ability to cool itself, with sweating becoming the main way to regulate temperature when the air outside is hotter than the skin. Anything that reduces sweating or makes it harder for the body to cool down, including dehydration, a lack of airflow, or certain medical conditions, can increase the risk of overheating. Experts warn that heat exhaustion and heatstroke can affect anyone and, in severe cases, can become life-threatening if left untreated.
Additional Tips to Keep Homes Cooler
To help keep homes cooler, households are advised to close curtains and windows in sun-facing rooms during the hottest part of the day. Windows can then be opened later in the evening or overnight, when the outside air is cooler, to improve ventilation. People are also encouraged to avoid strenuous activity during the hottest hours, usually between 11am and 3pm, wear loose-fitting, light-coloured clothing, and drink plenty of water throughout the day to stay hydrated.
Summer Outlook
The Met Office's three-month outlook suggests warmer-than-average weather is more likely across the UK this summer, although periods of rain and more changeable conditions are still possible. Forecasters say the long-term warming trend means heatwaves are expected to become more frequent, longer-lasting, and more intense in the years ahead.
