Sleep and asthma (adult)

3) How sleep process affects breathing

There are 3 stages of sleep:

  • Light sleep.
  • Sleep where heart rate and breathing become regular and your temperature lowers.
  • Deep sleep, where breathing slows and muscles relax.

Airway resistance increases a night, whether awake or asleep. This increase is greater though during sleep. So airway function decreases as you progress through the 3 stages of sleep.

This is true for everyone but the effect is greater with asthma.
