Preventive circadian medicine: improving health with sleep checkups.

Abstract

Sleep plays a crucial role in health, and illnesses can impact sleep. In this Perspective, we introduce the concept of "sleep checkups," which use wearable devices to objectively and continuously measure sleep, providing feedback to enhance health and detect early signs of illness. Sleep checkups not only benefit individuals but also advance scientific understanding of sleep's role in health, offering significant potential for participants and global public health.
