Undergraduate students who used the Calm mindfulness app for 30 days showed reduced state anxiety, stress, and improved sleep quality compared to a control group. In the treatment group (37 students), state anxiety averaged 12 (SD 7.8) versus 14 (SD 7.4) in controls, state stress averaged 15 (SD 8.5) versus 20 (SD 8.8), and sleep quality scores averaged 6.4 (SD 3.5) versus 7.7 (SD 2.7). Perceived stress was also lower in the treatment group. The pilot findings suggest that a mindfulness app may help reduce anxiety and stress and enhance sleep quality among undergraduates, though a larger trial is needed to confirm.
