Hypercapnia = increase level of carbon dioxide (CO2) in blood
More CO2 = more stimulation of vagus nerve and depression of sympathetic neurons = you can fall asleep faster.
How do you get more CO2 without taping a paper bag to your mouth at night?
It’s easy… follow the diagram!
Inhale for 4
Hold for 6
Exhale for 6
Hold for 6
Repeat!
Having more time spent not-inhaling allows you to build up CO2 safely!
