How many evenings should I record my sleep breathing?

Recording frequency for best results

Sleep breathing patterns and sleep apnea symptoms can change from night to night and can worsen with age, weight gain, stress levels or with some medical conditions. The quality of an individual’s sleep can also vary with sleeping posture, eating and drinking habits, or with medications.

For these reasons, testing for three nights is advised in order to obtain the most accurate picture of an individual’s sleep.
