An NHS doctor has provided a rationale for why the UK feels hotter than other places under the same sun - and the explanation is quite logical.
If you've experienced the warmth abroad, you're aware that 25°C feels vastly different from 25°C in the UK. While Brits are known for grumbling about the weather, there may be legitimate reasons for their grievances.
Taking to TikTok Dr Karan Raj aka @dr.karanr pondered that question: "Why does the heat in the UK feel even hotter than when you're abroad?" Joking that we love to complain about everything, weather included, he said there are "a few rational explanations for this temperature perception glitch".
Firstly, he says it has a lot to do with relative humidity. He explains: "This is the amount of moisture in the air compared to the maximum amount of moisture the air can hold at that temperature.
"In the UK, the relative humidity is higher than in countries with dry heat. This makes it harder for our bodies to cool down because sweat doesn't evaporate as well. So you feel hot and sticky like a roast barbecue pig. This is why 35C in a dry climate can feel more comfortable than 25C in a place with high relative humidity."

He said our infrastructure was another factor. He said: "In the UK the buildings are designed to retain heat because the weather is usually cold, soggy and silly.
"The same insulation that helps save energy in the winter makes buildings a greenhouse in the summer, especially without air conditioning which most UK homes don't have.
"In contrast, buildings in warmer climates are designed to stay cool. Thick walls and large windows sometimes even with window shutters and coloured coatings on the buildings to deflect heat."
Tips for coping in hot weather
The NHS advises avoiding heat exposure when possible. If you must go outside, seek shade during peak sun hours from 11am to 3pm, wear sunscreen, a hat, and light clothes, and avoid activities that raise your body temperature.
Keep cool by eating cold dishes and drinking cool beverages, avoid alcohol, caffeine, and hot drinks. You should also take cool showers or dampen your skin or clothes with cool water.
They also recommend keeping your home cool. Close windows during the hottest parts of the day and open them at night when it's cooler. Use fans when temperatures are below 35 degrees Celsius and keep track of the temperature in rooms, particularly those occupied by vulnerable individuals.
