Study Finds Daily Exercise, Quality Sleep Vital for Enhancing Happiness, Reducing Stress

New Delhi: Engaging in regular physical activity and ensuring adequate sleep may significantly enhance happiness levels while cutting down stress, suggests a recent study.

Researchers from Harvard University (US) and Oxford University (UK) conducted a pilot study examining the key factors influencing happiness and overall well-being. Utilizing data gathered from smartwatches and smartphones, the study aimed to offer insights for shaping public health policies and developing wellness-focused products. The study was conducted in collaboration with smartwatch manufacturer Garmin and involved over 10,000 participants globally.

Key findings revealed that individuals who maintained a consistent exercise routine and achieved sufficient sleep reported higher happiness levels and lower stress. Moreover, the research highlighted that emotional stability was strongly influenced by age, with older adults displaying greater emotional steadiness compared to younger participants who exhibited more variability in mood.

Interestingly, participants showed a high level of engagement throughout the study period, indicating the perceived value of tracking emotions and lifestyle habits in real time. The research further noted that individuals experienced peak happiness when involved in social or cultural activities, sharing meals, or spending quality time with friends and family.

These findings are in line with earlier studies emphasizing the benefits of physical activity in managing stress. Exercise helps regulate stress hormones such as cortisol and promotes the release of endorphins—chemicals in the brain associated with improved mood and reduced pain perception. Additionally, regular workouts contribute to better sleep quality, which is often compromised due to high stress levels, thereby creating a positive cycle for emotional well-being.

Exercise not only boosts mood and self-esteem but also enhances resilience and fosters a sense of control, which can be critical in coping with daily stressors.

Stress remains a major public health challenge, linked to various mental health disorders like anxiety and depression. It also exacerbates chronic diseases such as diabetes, hypertension, and obesity, and can affect gastrointestinal health, immune function, skin conditions, menstrual cycles, and fertility.

The study underscores the urgent need to prioritize lifestyle interventions as stress-related illnesses continue to contribute to substantial productivity losses globally, with an estimated 17 million working days lost annually due to stress, depression, or anxiety.
