The best day and time of day: researchers have discovered when people experience their peak happiness.

University College London conducted a study on the relationship between mental health and happiness in relation to the day of the week and time of day. Researchers analyzed nearly a million responses to questions and arrived at intriguing conclusions, as indicated by the test results.

For two years, 50,000 individuals answered the questions. It became clear that, generally, people are happier in the morning when their mental state is at its best. The worst and most depressive time of day is midnight.

The happiness level among respondents increased during the study, which took place at the peak of the coronavirus pandemic from 2020 to 2022. Happiness and life satisfaction were highest on Mondays, Tuesdays, and Fridays, while Sundays saw the lowest levels.

"Of course, the results of the study are intriguing, and they need to be replicated in other series that fully account for all possible biases," commented the lead author of the study, Dr. Feifei Bu from the Department of Behavioral Sciences and Health at University College London.

The very notion that most people experience their happiest moments in the morning suggests that their condition may decline over time. However, experts indicate that mornings are not a source of happiness overall.

Notably, respondents were not asked what time of day they feel their best. Instead, they were questioned about their mood and mental health, and their answers were then compared to the time of day when they responded.

As a reminder, scientists have managed to find a way to reconstruct the ancient climate of the Earth. This was made possible through the use of wood anatomy.

In one of the studies, researchers revealed a unique ability of humans to suppress fear. The calmness response is linked to brain activity.
