A recent study published in BMJ Mental Health offers new insights into the ways mental health fluctuates throughout the day, week, and across the seasons. The findings indicate that people generally experience better mental well-being in the morning, while midnight is marked by the lowest mood levels. The study also highlights significant challenges in mental health during midweek days and the winter months.
Morning Boost, Midnight Slump
The study, based on data from the University College London COVID-19 Social Study, followed participants from March 2020 to March 2022. Researchers found that individuals typically felt their best in the morning, reporting lower levels of depressive symptoms, anxiety, and loneliness, as well as higher life satisfaction and happiness. However, these positive emotions gradually declined throughout the day, reaching their lowest point around midnight.
Weekdays vs. Weekends
Mental health patterns also showed variation depending on the day of the week. Mondays and Fridays were associated with higher levels of happiness, life satisfaction, and a sense of purpose, while Tuesday saw the peak in happiness. On weekends, participants reported more mood fluctuations, although loneliness remained consistent throughout the week.
Seasonal Impact on Mental Health
The study identified winter months as a particularly challenging time for mental well-being, with participants reporting higher levels of anxiety, depression, and loneliness. Summer, by contrast, emerged as the most favorable season for mental health, though seasonal changes did not significantly affect the daily fluctuations in mood.
Biological Rhythms and Mental Well-Being
Researchers point to biological rhythms, particularly fluctuations in cortisol levels, as key factors influencing these patterns. Cortisol tends to peak in the morning and decline throughout the day, which may explain the variation in mental health observed in the study. Other contributing factors include changes in daily routines, exposure to natural light, and sociocultural influences.
The study underscores the importance of providing targeted mental health support during vulnerable times of day, midweek days, and during the winter months. Experts believe that recognizing these patterns can help improve mental health services and interventions, ensuring they are available when most needed.
