                                According to a 2018 study involving male subjects eating a solid meal, a significant decrease in sleep latency (the time it takes to fall asleep) was observed. This common phenomenon, colloquially known as a 'food coma,' is medically referred to as postprandial somnolence, and it explains why you feel tired after eating a lot.
