Question

Why do we feel cold after taking hot water bath?

Answer 1

We feel cold after taking a hot water bath because our bodies get used to the warmth of the water and once you get out, your body is no longer used to the normal air that you usually would be fine with. Something similar to this is if you put one of your hands in cold water for a minute and the other hand in hot or warm water for a minute, then put both hands in room temperature water, your hands will feel different from each other even though they are in the same temp.water at that moment. 

Answer 2

Answer:

Waking up is hard, but for some of us, getting out of the shower in the morning is harder. Things are dandy at first: You step into the basin and happily roast under a steamy blanket of hot water. But then you shut off the shower faucet, open the curtain, and whoosh! You’re a human popsicle. Why does stepping out from a warm shower make your bathroom feel like Antarctica?

The answer is evaporation. When you step off the bathmat, the water clinging to your skin starts to evaporate. But to change into a gas, that water needs help—namely, it needs heat energy. It acquires that energy by sapping heat from your surroundings. In the case of your morning shower, the evaporating water sucks up heat energy from the droplets that stay clinging to your body. The result? The water on your body cools—and so do you. (The water glistening on your skin isn’t the only thing that gets icy. Evaporation also absorbs heat from your skin, making you shiver even more!)
