Take a shower with cold water, why do people who go in outside think it s hot inside the bathroom?

It's the same principle that people feel stuffy before a rainstorm in the summer. People rely on sweat to release heat, the faster the sweat is evaporated, the cooler it will feel, the water vapor evaporates, from the liquid to the gas will absorb heat, so the human body will feel cool, but when people enter the bathroom to wash, the indoor water vapor is dense, the air humidity increases, so that the water vapor is not easy to be evaporated, the sweat or the water droplets on the body still maintain the liquid form, the water vapor evaporates into gas and the ability to absorb heat is weakened, the temperature of the human body has not been dissipated, and it is dense in the bathroom, so although there is water, It still doesn't stop the body heat from increasing the temperature of the bathroom, and the body heat can even drive the temperature of the moisture in the bathroom.

Don't you feel that the cold water turns warm when it flows through your body? Cold water will take away the heat from the body surface, due to the stimulation of cold water, the muscles under the skin will produce heat, thyroid hormones and adrenaline will also increase, these are for heat production, so the heat on the body surface will also be transferred to the air, and the small water droplets floating in the air are carrying the heat.

In fact, it is stuffy and wet, and it causes discomfort.

It's like the rainy season, but the temperature is not too high, and there is no sun yet. But it will feel hot, because it is stuffy and mocking, there is no wind, and the air does not flow. It feels sticky on my body.

If the humidity in the air is high, it will make people feel stuffy, and the actual temperature is not high.
