Seasons significantly affect how much time we spend in daylight
The analysis included 58,350 participants from the USA, who together provided more than 9.6 million days of records. The results show significant seasonal differences: while in January participants spent an average of 30.8 minutes outdoors per day, in June the average increased to as much as 102.1 minutes.
Daylight affects stress levels
An important part of the analysis was the relationship between the amount of daylight and the level of subjectively perceived stress. Participants who, on average, spent more than 90 minutes per day in the light showed a 22.8% lower likelihood of high stress than those who spent less than 40 minutes outdoors. This result confirms existing scientific findings about the positive effects of natural light on mental health and overall psychological well-being.
Light has an impact on our health
The study thus offers a new, strongly data-supported perspective on everyday exposure to light and its connection to health. It points out that even a relatively small increase in time spent in natural light can have beneficial effects on both physical and mental health and overall vitality.
