NOWATCH products and services are not medical devices, and are not intended to mitigate, prevent, treat, cure or diagnose any disease or condition. If you have any concerns about your health, please consult your doctor.

Technically, the NOWATCH should work for everyone. However, there are things that may affect its accuracy.

For example, if there is something that is affecting your blood flow circulation such as vascular disease, then measures derived from the PPG sensor will not be as accurate.

Likewise, if there is something affecting your sweat gland activity such as hyperhidrosis and hypohidrosis, then measures derived from the EDA sensor will not be as accurate.

Finally, movement problems like Parkinson's may also affect measurement accuracy.

On the other hand, endocrinological issues that affect cortisol production will not have any effect on measurement accuracy.
