As the UK braces for a heatwave, experts have suggested using tin foil on radiators to keep homes cooler. The advice, originally given for cold weather, is being repurposed for summer heat. Attaching silver foil to the back of radiators reflects heat back into the room, but in hot weather, it can be used to reflect heat away from the house if placed on external walls.
Specialist radiator foil costs around £8.38, but regular tin foil is considered just as effective when fixed firmly to the wall. Experts also recommend keeping radiators clear of obstructions to allow air to circulate freely. For cooling, placing a bowl of ice in front of a fan can help lower room temperature.
Other tips include drinking iced coffee instead of hot, as caffeine can stimulate metabolism and warm the body, but cold drinks can trigger a rise in core temperature. Microwaving socks filled with grains for 20-second bursts can provide a cooling effect if frozen, or warmth if heated.
Spices like turmeric, chilli, and cinnamon can also help regulate body temperature. Turmeric contains curcumin, which improves blood vessel health and circulation. Half a teaspoon in tea or coffee can aid cooling by promoting sweating.
