Why do you feel cold when drink water?

You don't actually feel cold when you drink water. In fact, the temperature of the water you drink has very little to do with how you feel. What really matters is the rate at which your body loses heat.

When you drink cold water, it absorbs heat from your mouth, throat, and stomach. This can cause you to feel cool momentarily, but your body quickly compensates by increasing its blood flow to those areas. As a result, you end up feeling just as warm as you did before you drank the water.

In some cases, drinking cold water can actually make you feel hotter. This is because your body works harder to warm up the cold water to body temperature. This process can release heat into your bloodstream, making you feel flushed and sweaty.

So, if you're looking to cool down on a hot day, drinking cold water isn't necessarily the best way to do it. Instead, try taking a cool shower or bath, or eating a cold treat like ice cream or popsicles.
