Why do people get sleepy after eating a big meal?

• The sugar from food stimulates the sympathetic nervous system.

• Digestion is increased by the parasympathetic nervous system, which also relaxes the body.

• The body needs to maintain homeostasis of blood sugar concentration, so the body shuts down.

• The body switches over to the parasympathetic system because the sympathetic system has been active for too long.
