Why hearing less sharp after eating too much meal?

After eating a large meal, blood flow is redirected to the digestive system to aid in digestion, which can result in temporary reduced blood flow to other areas, including the ears. This can lead to a sensation of muffled hearing or a decrease in auditory sharpness. Additionally, the body may experience a general sense of fatigue and relaxation post-meal, which can further affect alertness and perception, including hearing.
