why do people get tired after they eat?
In: 298
Well imagine a bunch of people transporting energy to different sites. They all start from the main site. But now the main site needs to convert food to make energy and nutrients. So all the people don’t go to the different sites but stay at the main site to help keep the energy in one place.
This is why you feel tired after eating. Because digestion takes a lot of energy at the beginning, so the body slows down blood flow to other organs, including your brain, making you feel tired.
Also this is why they say “don’t shower or swim after eating” because blood flow is redirected to cooling/heating your body rather than digesting.
