Households urged to turn off TVs, laptops and chargers on Thursday

Households are being urged to switch off televisions, laptops and chargers on Thursday as high temperatures are expected to push up the heat inside homes.

Health experts say electrical devices that are not being used should be turned off during hot weather, as they generate extra heat and can make already warm rooms feel even hotter.

The advice comes as the Met Office says there is a greater chance of hotter-than-average conditions this summer, with heatwaves becoming more likely across the UK.

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.

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.

Another simple step is to switch off non-essential electrical items. Televisions, laptops, games consoles and chargers all give off heat while in use or plugged in, which can raise indoor temperatures.

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, making it increasingly important for households to take simple steps to stay safe during spells of hot weather.
