When Does Breathing Slow?

Published in Respiratory Conditions 1 min read

Breathing slows down, a condition known as bradynea, when the respiratory rate becomes abnormally low. This slower breathing can be an indication of an underlying medical issue.

Causes of Slow Breathing (Bradypnea)

  • Underlying Health Conditions:
    • Hypothyroidism: An underactive thyroid gland can slow down bodily functions, including breathing.
    • Head Injuries: Damage to the brain can affect the respiratory control center.
  • Substance Use:
    • Opioid Use: Opioids are known to depress the respiratory system.
    • Heavy Alcohol Use: Excessive alcohol consumption can also lead to slowed breathing.

Associated Symptoms

In addition to a slower breathing rate, individuals experiencing bradypnea might also show other symptoms like:

  • Dizziness
  • Confusion
  • Feeling Tired
