Crying can make you feel tired due to physiological changes that occur in your body.
The Physical Impact of Crying
When you cry, several physical changes take place, which contribute to the feeling of exhaustion. According to research, a key reason for the fatigue experienced after crying is related to changes in your breathing and heart rate.
Reduced Oxygen to the Brain
The physiological process of crying involves:
- Increased heart rate: Your heart beats faster as you express intense emotions.
- Slowed breathing: The pace of your breathing decreases.
This combination of an increased heart rate and slower breathing reduces the amount of oxygen circulating in your bloodstream. Consequently, less oxygen reaches the brain. This decrease in oxygen supply is what leads to the feelings of tiredness and dizziness that often follow an emotional release.
Summary
In short, the act of crying causes a shift in your body's natural rhythm, leading to less oxygen reaching your brain, and subsequently, the sensation of tiredness.
