Why Choose Emfit QS?

Sleeping Problems
Sleeping time constitutes more than one third of our entire lifetime. If sleeping has problem, our living, emotion and productivity will be badly affected. Research finds that over 40% Hong Kong citizens are puzzled by the sleeping problem, which is more serious than in western countries. 
Improve sleeping quality
EMFIT QS, designed and manufactured in Finland, is the world first contact free sleep tracker with heart rate variability. It can monitor your physical & mental recovery and sleep quality, helping in daily routine & training planning. General principle behind Emfit QS is that "when you can measure, you can manage". This means that while you measure your sleep, recovery, and stress levels, you start to find out the correlations between certain measurements and certain lifestyle choices. And you can therefore root out the problem by changing your habits or behavior.
World’s First Contact Free Sleep Tracker with Heart-Rate-Variability
Emfit QS unshackles your mind from any health tracking devices. There’s no need to wear a straining chest strap or wrist band, and no need to turn equipment on and off. Just lay down on your bed, sleep tight and check your bed-time data in the morning from your smartphone, tablet or computer.

Monitor cardiovascular fitness and mental stress
Through monitoring HRV, one can see whether his/her cardiovascular fitness is increasing, as baseline HRV increases along with it. In short term, HRV gives valuable information about stress and recovery. The decrease of HRV from the baseline indicate heavy physical or mental stress. It’s better to recover till the HRV return to baseline value.

Sky Christopherson:
“Working with Olympic athletes, we use ‘Data not Drugs’ to boost every aspect of athlete health and performance. Since sleep is foundational to health and performance, it is a focal point of our program and we have used every sensor on the market. Emfit is creating new capabilities in understanding sleep both with the goal of improving it, but also using it to better inform training decisions as we moved towards truly individualized training.
The ease of use and accuracy of Emfit is also unprecedented. As a result, Emfit is now an integral part of our ‘Data not Drugs’ program as we build a future that uses more data and less drugs, in sport, and hopefully in health.”
