The (European) sun is a deadly laser, stay safe everyone
☝️🤓 it’s because the further you move toward the earth’s poles, the lower the angle of the sun is at the hottest parts of the day, meaning the radiation hits your whole body, causing it to feel 10-20 degrees warmer than the thermometer reading will tell you. People from tropical climes, aka close to the equator, are used to the sun’s radiation hitting a much smaller target- their head and shoulders.
Also the further you move toward the poles the more pronounced the difference between the length of day and night is. Worst part of a far-north (or south) heatwave is it doesn’t get dark long enough for meaningful cooling.
It’s not the heat. It very literally is the sun.
People keep saying the humidity, and yes a humid heat is a specific kind of misery and can be dangerous… but critical to remember, many many tropical climes are humid as well.
Infrastructure and citified heat islands also very much play a factor. And here the angle you’re at on earth also makes it worse. The sun being lower on the horizon can double the amount of solar energy affecting your house. The sun beating through your windows for 16+ hours a day when you have a house built for cold and no AC adds to the misery.
But what I’m talking about here is how hot you feel in your body when experiencing solar radiation from a lower angle. On the upside the sun’s rays have to pass through more atmosphere, weakening the UV strength, hence why populations that migrated north eons ago lost melanin (you still need SPF though). And in general the warming effect on the atmosphere is lessened. The warming effect on your body is magnified. To the tune of 10-20 degrees (yes Fahrenheit) above ambient. Winter gear prioritizes insulating your torso because that’s where all your vital organs are. It follows that the sun beating on your chest and back warms you up fast and with little relief except to get in the shade.
Visitor to Alaska are often surprised at how warm temperatures in the 70°s and 80°s feel. Read about how this phenomenon occurs.
My eye doctor also told me living in Alaska made you more likely to get cataracts younger because the low-angle sun gets directly in your eyes in the summer (unless you’re big on sunglasses) and the snow and ice in winter reflect a lot of UV back up, doubling your exposure. Though the prevalence of cataracts in Alaska and other far-north locales is contributed to by other factors, notably poverty and the resulting lack of medical care. And is still not as likely as in people who live in equatorial climes or high altitudes and get the super-strength UV exposure all year round.
