Why do emotions such as anger or fear slow digestion?

The “fight or flight” response, a physiological reaction to stress, anger, or perceived danger, can affect digestion. When the body experiences stress or fear, it releases stress hormones such as adrenaline and cortisol. These hormones can cause various physical changes, including increased heart rate, blood pressure, respiration, and reduced blood flow to the digestive system. As a result, digestion may slow down or come to a halt temporarily. 

The same is true of the emotion of anger, which is also associated with the “fight or flight” response. It is worth noting that while emotions can affect digestion, they are not the only factor that can influence digestion. Other factors such as diet, exercise, and underlying health conditions can also play a role.
