Product Description

Sleep is paramount to peak performance – both physical and mental

It is essential to get enough sleep, but sleep should also be structured properly and contain enough REM sleep for the recovery of the mind, and DEEP sleep for the recovery of the body. EMFIT QS+ACTIVE records total amount and structure of sleep, the percentages of recuperating REM and DEEP sleep.

EMFIT QS+ACTIVE also records heart rate, breathing rate, and movement activity during the entire night. Overall, it enables you to find sleep affecting patterns and improve them. Results of training or lifestyle changes can be studied with the long-term trends feature.
