Why is sleep monitoring becoming such an important health trend?

Sleep monitoring is becoming more important because newer devices can show more than how long a person slept. By tracking oxygen levels, heart rate, breathing patterns, movement, and other overnight signals, they can help reveal why sleep may not feel restorative. These patterns may give people and their healthcare providers useful context about fatigue, stress, irregular routines, or chronic conditions that can worsen when sleep is poor. The article presents sleep monitoring as a practical way to better understand the connection between nightly sleep and overall health, making it easier to identify meaningful changes instead of relying only on a single sleep score or personal impressions.
