Normal sleep efficiency is about 85% or higher. We recommend that you wait 4-7 days before making any assessments about your sleep patterns. It is normal for some people to have an off night or two during the week. In addition to your sleep efficiency, it is also important to make sure you get the recommended amount of sleep, which can vary for each person. You can see your sleep data in the Philips HealthSuite health app, once your health watch syncs.
For accurate sleep tracking indicated sleep intent is essential.
