Eli5: Does drinking hot water replenish more energy because hot things have more energy in them?
In: Biology
It is not that simple. Your body is not able to use energy dircetly from heat. Overheating can actually be a problem and your body might have to use energy to get rid of excess heat. So you might actually lose energy by drinking hot drinks rather then gain energy. On the other hand in cold climates the body needs to use energy just to stay warm. And in this case drinking hot drinks may help the body conserve energy since it will get hot from the drink instead of having to use its own muscles just to generate heat.
No. Although your reasoning is right about the energy, you’re missing that energy expresses itself in a lot of ways. Energy related to temperature is called cinetic energy, and depend of the ‘level’ of excitation that particles of something have.¿
Besides, the human body obtains energy in a lot of ways, but we obtain the most by the chemical process of ‘extracting’ calories (and some other things of course) from food which is called metabolism, and it’s related of course with the amount of calories and the other things contained in food.In this case, water has no calories, so hot water will have a high level of cinetic energy but it’s still water. ‘Chemically’ speaking, it’s still water with zero calories.
No, we gain energy through our metabolism. We do not have the ability to convert heat energy into usable energy for ourselves.
You could make an argument that warmer water will require less energy to absorb since your body doesn’t have to warm it up, but that’s not significant.
Drinking water replenishes no energy, but it’s required for that systems in your body that do replenish energy to work.
I’m presuming you mean energy that the body can use?
The short answer is no. The long answer is no, that’s not how we generate energy at all.
We actually expend energy to keep our bodies at a regular temperature whether it’s warming up or cooling down and hot water rapidly cools to body temp anyway.
