With the arrival of spring, changes occur in the human body associated with increased vigor and a different perception of colors. This occurs due to an increase in serotonin levels.

Scientists from the United States of America have conducted an extensive study of the perception of all kinds of colors by our vision at different times of the year.

It turned out, for example, that in summer yellow is perceived by the human eye closer to green. In winter, such metamorphoses with vision are not observed.

Scientists from Germany claim that the reason may be in drowsiness and inactivity, typical for people in winter. In spring, the body becomes more active, causing serotonin to be released.

The content of serotonin in the human body increases noticeably in spring. This affects people's enjoyment and improvements in emotional stability. Scientists have concluded that in spring the human body, like all of nature in general, “awakens”, gaining strength and vitality.
