Stress, as the study highlights, is a major health risk factor. It is closely linked to a variety of mental health conditions, including anxiety and depression
Daily physical activity and sufficient sleep play a crucial role in enhancing happiness and reducing stress levels, a recent study revealed. Conducted by researchers from Harvard University (US) and Oxford University (UK), the study provides valuable insights into predictors of well-being, showing how simple lifestyle changes can significantly impact mental and emotional health.
The research team examined data collected from smartwatches and smartphones to understand how various factors influence happiness and stress. The study, which included more than 10,000 participants worldwide, was conducted in collaboration with smartwatch provider Garmin. It aims to inform global public policies and product development, particularly in relation to improving mental health and well-being on a global scale.
One of the key takeaways from the study is the positive impact of daily physical activity on reducing stress and boosting happiness. The researchers found that exercise plays a vital role in managing stress, primarily because it helps regulate stress hormones and triggers the release of endorphins. These “feel-good” hormones not only elevate mood but also reduce pain, leading to an overall sense of well-being. Regular physical activity is also associated with improved sleep quality, another important factor in managing stress and boosting happiness.
According to the study, exercise helps individuals cope better with the daily pressures of life by improving mood and boosting self-esteem. The act of physical exertion fosters a greater sense of control and resilience, which is essential when facing stressful situations. This is particularly important given the widespread concerns about stress and its negative impact on health.

Stress, as the study highlights, is a major health risk factor. It is closely linked to a variety of mental health conditions, including anxiety and depression. Furthermore, chronic stress can exacerbate noncommunicable diseases such as diabetes, hypertension, obesity, and even certain types of cancer. Stress can also trigger gastrointestinal issues, weaken the immune system, and cause skin problems. It has been found to disrupt the menstrual cycle in women and negatively affect fertility as well.
The study also revealed that emotional stability tends to vary with age, with older adults showing more consistency in their emotional responses compared to younger individuals, who exhibited more variability in their emotions. This finding underscores the importance of emotional regulation in the face of stress, particularly in younger populations who may struggle with stress management.
Another interesting insight from the study was the high retention rate of participants, suggesting that individuals found value in self-monitoring their emotions throughout the day. This indicates that people are increasingly interested in understanding and improving their mental health, possibly through wearable technology that helps track emotional and physical well-being.
The researchers also discovered that individuals felt happiest when engaging in cultural and social activities, eating, or spending quality time with family and friends. These activities have long been associated with improved emotional well-being, and the study provides further evidence of their positive impact on happiness.
In addition to exercise and sleep, the research emphasizes the importance of a balanced lifestyle, with a focus on mental and emotional well-being. By understanding the factors that contribute to happiness, the study suggests that individuals can take proactive steps to improve their quality of life and manage stress more effectively.
The findings of the study are timely, as stress continues to be a growing concern globally. According to the World Health Organization (WHO), approximately 17 million working days are lost each year due to ill-health caused by work-related stress, depression, and anxiety. As stress becomes more prevalent in modern life, the study’s insights into how exercise and sleep can mitigate its effects provide a valuable resource for individuals and policymakers alike.
Ultimately, this research highlights the importance of incorporating physical activity and healthy sleep habits into daily routines. The findings not only reinforce the benefits of exercise and sleep but also suggest that these lifestyle changes can serve as effective tools in the fight against stress and its associated health risks. By making these small yet impactful changes, individuals can significantly enhance their well-being and reduce their stress levels, paving the way for a happier and healthier life.
