How do cooling blankets work? Like what causes them to be "cold to the touch" without needing electricity or storing them in a freezer beforehand? Or is it all just a scam?

If there's no active cooling (electricity or fluid flow) then they work passively that is to say they barely work. Basically they are just breathable blankets that keep the skin dry and let the moisture evaporate. There may be some meme materials incorporated if it's expensive product as well that may conduct or help absorb heat and the weave is generally pretty high thread count and other tricks to help with it's breathing.
They don't really cool anything but they may be more comfortable feeling and feel cooler to the touch which is half the battle for lot of people.

You know heatpipes? Now make them so thin you can weave a fabric. They will transfer heat from center to the sides. Why wouldn't this work?

>man that has never touched metal confused by the principles of conduction
This is not google, retard.

Just minimize heat retention and insulation and maximize surface area. Same way heat sinks work.

The only fabric that kind of works is Outlast it uses phase change material. After a while it reaches equilibrium so it's not indefinitely cooling but it's better than most gimmicks.

>In our material, the heat from the user's body melts the wax. Therefore, the thermal energy is used in the phase change. According to a physical law, temperatures can not further increase during this change. And that is why the temperature of the user's body will no longer rise and remain stable instead. A similar thing happens when the body, our former heat source, cools down. Now, the thermal energy is used in the process of making the wax change from a liquid state into a solid state. The user does not get any colder and can further enjoy a stable and comfortable temperature.

Marketing has gone too far.

Just sleep on the ground, the greatest heatsink of them all

Sleep in the river

this is my bed. big fan blows on me, open window.

>>16703031
wtf is going on here anon? You sleep against the window with it at an odd angle....

>>16703753
need fresh air, also my mattress is caved in at the middle, don't ask haha
anyhow, i could never be married or share a bed

>>16703817
anon put a sheet on, please
if not for your mattress then for you

>>16700958 (OP)
wait, they make cooling blankets?

>>16704437
cooling mattreses too, brian johnson has one, he sleeps in a pitch dark room with total temperature control

heatpipes contain a vacuum inside if I remember right. It would take nanotechnology

Is OP picrel possible?!?! This has been a problem all my life. Women like it scorching hot in the room and I can't even fall asleep if it's not chilly, I wake up in a pool of sweat, it's horrible.
