Points to watch

⚠️Hyperventilation
Understanding
Hyperventilation is a breathing pattern that is too fast or too intense.
It reduces the level of CO₂ in the blood and may cause:
* dizziness
* tingling
* lightheadedness
* general discomfort

Safety instructions
* Do not speed up your breathing.
* Do not breathe forcefully.
* Do not chain rapid inhalations and exhalations.
* Do not continue the exercise for too long.

What to do if it happens
* Stop the exercise immediately.
* Sit down.
* Breathe normally.
* Wait for the sensations to disappear.
* Resume more slowly afterward.
