Mental health: physical activity and circadian rhythms in prevention
A mental health It is a fundamental pillar of individual and collective well-being, and its promotion in Cape Verde is emerging as an increasing priority. In an island context, where socio-economic and environmental challenges can affect the population’s psychological well-being, preventative and easily accessible strategies are essential. A promising approach lies at the intersection of regular physical activity and the regulation of circadian rhythms – the natural cycles of sleep and wakefulness that govern multiple biological functions, including those related to emotional health.
Regular physical exercise has consistently been shown to have significant benefits in improving mood, reducing stress and anxiety levels, and preventing depressive disorders. Exercise releases endorphins, known as ‘happiness hormones’, which act as natural painkillers and promote a sense of well-being. Furthermore, physical activity contributes to better sleep quality, a factor directly linked to emotional stability and the ability to cope with adversity.
Circadian rhythms, in turn, play a crucial role in regulating sleep and mood fluctuations. Exposure to natural light during the day and darkness at night, together with regular meal and sleep schedules, help to synchronise this internal biological clock. Disruptions to these patterns, often exacerbated by sedentary lifestyles, irregular working hours or excessive screen time, can throw the system out of balance and increase susceptibility to mental health problems. Raising awareness of the importance of these rhythms and encouraging consistent daily routines can be a significant step towards preventing and managing mental health issues.
Integrating physical activity into the daily routines of Cape Verdeans, making the most of the favourable climate and available natural spaces, and educating people on the importance of good sleep hygiene and regular circadian rhythms, represents a cost-effective and sustainable strategy. The implementation of community programmes that encourage regular walks, outdoor exercise classes and workshops on sleep and wellbeing can have a lasting positive impact on the nation’s psychological resilience. This integrated approach aims to empower individuals to take an active role in maintaining their mental health, thereby strengthening the community as a whole.
