Do We Still Breathe When We Sleep?
It is a natural instinct for us to breathe in and out when we are awake and alert. But what happens when we fall asleep? Do we still breathe?
The short answer is yes, we still breathe when we sleep. However, our breathing patterns change slightly depending on the type of sleep we are in. When we enter a deep sleep, our breathing rate slows down, and our breaths become shallower and longer. During REM (rapid eye movement) sleep, our breathing rate is similar to when we are awake, but our breaths may be more shallow.
Apnea is a sleep disorder in which a person experiences pauses in breathing during sleep. This can be caused by an obstruction in the airway, such as from narrow nasal passages or a large tongue. It can also be caused by neurological issues, such as a stroke or brain injury. People with apnea may wake up briefly during the night to start breathing again.
Hypoventilation is a condition in which a person does not take in enough oxygen while they sleep. It can be caused by conditions such as COPD (chronic obstructive pulmonary disease), asthma, obesity, and neuromuscular diseases. Hypoventilation can lead to low blood oxygen levels, which can be dangerous.
It is important to understand how our breathing patterns change during sleep and to be aware of any signs of sleep-related breathing problems. If you or someone you know is experiencing frequent pauses in breathing during sleep, it is important to seek medical advice.
