Why is human mood 'sunny morning, rainy afternoon'?

New research shows that human mood can be greatly influenced by time factors, specifically the time of day, day of the week, or season of the year.

A study published in the journal BMJ Mental Health found that the time of day or season of year affects people's moods, including symptoms of depression, anxiety, happiness, life satisfaction, sense of purpose and loneliness.

Research shows that many people feel happier and more satisfied with life on Mondays and Fridays than on Sundays.

The researchers analyzed data from the University College London (UK) "Social Study of Covid-19" which collected information from 49,218 people, starting in March 2020 and lasting until March 2022. The results showed that people usually wake up in the best mental state in the morning, while their mood drops to its lowest point around midnight. Even factors such as the day of the week and the season of the year have a similar effect.

More specifically, the study found that mental health changes more on weekends than on weekdays. Happiness and life satisfaction were both higher on Mondays and Fridays than on Sundays.

Mental health was best in the summer across all outcomes and worst in the winter. In other seasons, people’s levels of depression, anxiety, and loneliness tended to be lower. At the same time, they reported higher levels of happiness, life satisfaction, and a greater sense of meaning in life.

The researchers say the differences in mood between the two sessions of the day may be due to physiological changes related to the body clock. "For example, cortisol peaks shortly after waking and reaches its lowest level around bedtime," the team said.

As for the main reason for seasonal mood swings, experts say it could be the change in daylight hours.

With people's mental health tending to be lowest around midnight, midweek and winter, the researchers expect "this needs to be considered when planning services and resources".
