Can Your Smartwatch Detect Depression Early?

A growing body of research suggests that something as simple as a smartwatch may help detect early warning signs of depression relapse. A recent study from McMaster University found that wrist-worn wearable devices can track sleep patterns that may signal a potential relapse weeks before symptoms appear.

For people living with major depressive disorder (MDD), relapse is unfortunately common. More than 50% of individuals experience another episode within two years after recovery. Early warning signs often include sleep changes, shifts in appetite, low mood, and loss of interest in daily activities.

In the study published in JAMA Psychiatry, researchers followed adults with a history of depression for up to two years. They discovered that irregular sleep patterns and disrupted circadian rhythms nearly doubled the risk of relapse. In other words, when the body’s internal clock becomes unstable—like going to bed and waking up at inconsistent times—it can impact emotional stability.

This research is especially important for Black communities. Black individuals with depression often face higher stress levels, more sleep disruptions, and barriers to consistent mental health care, all of which can increase the risk of relapse.

At Be Very Resilient, we encourage people to pay attention to everyday health signals—especially sleep. Tracking sleep patterns, maintaining consistent routines, and seeking support early can make a meaningful difference. Through therapy, psychiatric medication management, and mental wellness education, our goal is to help individuals recognize early warning signs and build strategies that protect their mental health.

Sometimes resilience begins with awareness—even something as small as noticing how well you slept last night.
