Are Those Viral ‘Cooling Blankets’ for Real?

Touched both objects. They are the same temperature, but wood Feeling Warm, isn’t it? Why is it? It’s not about the temperature of the heat. When your hand touches an object, the heat conductivity is interacted. The energy is transferred from your warm hand to the cool object until the two are the same temperature. However, it takes more energy to reach the temperature of your hand with a metal block. It feels cool because it forces your hand to lose more energy.

You will notice the same thing when you go swimming. The air temperature of 75 degrees Fahrenheit feels beautiful and comfortable but it feels really cool to enter the same temperature water. This is because the air has a lot more mass and certain heat capacity than the air, thereby losing you more thermal energy and feeling cool.

Cool all the blankets

So, the blanket, how do they work? A blanket is essentially an insulator. This means it prevents the transfer of energy into the object at different temperatures. Keeping yourself in a blanket on a cold day prevents you from losing body heat in the air around you, so you feel warm. Similarly, if you put a blanket around a cold soda on a warm day, it will slow down the air to soda with soda. Cold Long

But if you feel hot and you keep a blanket? In that case two things can happen at once. It can still act as thermal insulatory and slow the energy transfer between you and the wind. If the ambient air is not above 98.5 degrees Fahrenheit it will make you warm, not cool.

However, the blanket may also contain thermal interaction with your body. Suppose you have an 80 ° F blanket in contact with a 98 ° F person. This will increase the temperature of the blanket when your body’s thermal energy is reduced. Yes, it will act as a cool blanket – for at least a few minutes, until the temperature is equal.

So, which one makes a blanket more effectively cool than the other? First, it should have a high mass, so that it takes a lot of energy to heat. Second, the blanket needs to be well communicated to your skin to increase the thermal interaction. So, one of those light flopping blankets will not make you so cool. Other than that it is just a simple blanket.

But I’m sucking these things, so I bought a cheap “cooling blanket” online. (I know, someone will say that if you don’t get expensive) it is not effective)) Those who say that their cool blanket was in the sun and they have measured the temperature of 75 ° F, I don’t believe you. Check it. There are three blankets on my sofa. One of these is cool blankets and the others are normal. The same image on the back is taken with an infrared camera so that different colors represent different temperatures.
