Duration and frequency of application
In order to prevent the above mentioned hyperventilation, the active breathing exercises should only be performed for a short period of time. No longer than 3 minutes, then you should return to normal relaxed breathing. Relaxation exercises (e.g. from autogenic training or dream journeys) can help if the breathing exercises are not sufficient to help you fall asleep.
The exercises can be done every evening before going to bed, or can be performed as needed. Relaxation techniques can be trained, and regular performance will increase the success of the exercises. Breathing exercises can also be used in everyday life to protect oneself from stressful situations and stressful (psychological) efforts by allowing a little time out.
