I was in Kuwait at the end of July back around 2010, and the temperature was in the 120s. I remember getting off the airplane and thinking that we were walking through the exhaust of the jet engine, until I realized that's just how the air feels for a big chunk of the year. You get used to it, but it feels like someone is pointing a blow dryer in your face any time the wind blows.
- mikkelam 6y agoI used to live in Dubai.. The summers there were spent indoor in AC as much as possible. 5 minutes outside going to the supermarket and I was drenched in sweat.. It literally feels like having your face over an open oven.
- perl4ever 6y agoDriving through Texas in the summer a long time ago, I got out of my car briefly and was struck by how my long pants were palpably trapping cooler air and shielding me, when I'm used to thinking of less clothing as being suited to hot weather.
- KozmoNau7 6y agoThere's a reason why traditional clothing in many very hot regions is loose, long and light (in both color and weight). Air is an insulator and clothes provide good UV protection.
- pa7x1 6y agoFor temperature you want IR protection.
- Valgrim 6y agoAll frequencies of light will transfer heat. UV light can cause damage to DNA because it's energetic enough to be ionizing (it can detach electrons). IR light is not ionizing, but we associate it with heat because the black-body radiation of things we generally interact with (humans and stovetops, for example) is mostly in the infrared spectrum. The sun is much hotter and emits light in IR, visible and UV spectrum.
- pa7x1 6y agoAll EM radiation carries energy and the higher the frequency more energy is carried by each photon but that doesn't mean that the energy is transferred as heat (i.e. increase in temperature of the body). The reason why IR is felt as heat is because it has the right wavelength to excite atoms and molecules unions into resonance. > IR light is not ionizing, but we associate it with heat because the black-body radiation of things we generally interact with (humans and stovetops, for example) is mostly in the infrared spectrum. In particular, this relationship is backwards. We don't associate heat with those objects because they happen to emit in the infrared. Since they emit in the infrared, they are good at heating (i.e. exciting molecular unions into vibration modes that make most of the energy stored). This is related to the fact that most of the mass of an object is associated to the nucleus, instead of the electrons. If it was the contrary, exciting electrons into higher energy states would be a better way to transfer energy into an object. On the other hand, UV protection is good to prevent high energy being transferred into electrons which then get excited into higher energy states messing up electronic bonds and potentially our DNA.
