Laughter relieves stress by​

A) ​helping you make jokes of difficult situations.
B) ​reducing stress-related hormones.
C) ​slowing your heart rate.
D) ​helping you sleep at night.

Laughter has been shown to reduce levels of stress-related hormones such as cortisol and adrenaline, leading to a decrease in stress and anxiety. While laughter may also help people cope with difficult situations by making jokes or promoting a positive attitude, the primary physiological mechanism by which laughter relieves stress is through hormonal regulation. Laughing does not necessarily slow the heart rate, although deep breathing exercises associated with laughter may have that effect. Similarly, while laughter may help people relax and fall asleep more easily, it is not a primary means of promoting sleep.
