Question

Laughter forces out
air from our lungs than during normal breathing.
​

Answer 1

Laughter helps to provide longer exhalations, thus ridding the lungs of residual air and enriching the blood with ample supplies of oxygen, the lifeline of our system.

As you breathe deeply during a hearty laugh, saturating your lungs with oxygenated blood, you may have to cough, sputter or spit. This is due to things loosening up in your respiratory system and getting a good fresh cleaning.
