Stress and inadequate sleep quality have a profound impact on the health, efficiency, and overall well-being of working adults. This research examines the impact of brief, practical stress-reduction methods, namely deep breathing and guided meditation, on perceived stress and sleep quality. A group of 50 working adults took part in a two-week program that included daily 10-minute sessions of these techniques. Perceived stress was evaluated using the Perceived Stress Scale (PSS), while sleep quality was measured with the Pittsburgh Sleep Quality Index (PSQI) at the start and end of the intervention. Statistical analysis revealed a significant decrease in perceived stress scores and a marked improvement in sleep quality after the intervention (p < .05). These results indicate that short, easily accessible psychological interventions can enhance health outcomes in workplace settings. The study advocates for the inclusion of simple, cost-effective stress-management strategies in workplace wellness programs to promote sustainable psychological and physical health. Future studies should investigate the long-term effects and assess digital delivery platforms to improve accessibility. This research aligns with the goals of applied psychology to create effective, scalable interventions that enhance health and quality of life worldwide.
