Spring Fever: Myth or Science?
“Spring fever” is a common yet not medically recognized phenomenon characterized by a change in mood and energy levels, often associated with the onset of spring and warmer weather, including feelings of restlessness or increased energy.
As winter fades and spring emerges, many people report feeling more energetic, optimistic, and even restless. This phenomenon, often called "spring fever," is widely recognized but not always understood. Is it merely a cultural myth, or does science back up the idea that spring brings changes in mood and behavior?
One of the biggest factors influencing spring fever is the increase in daylight hours. During the winter months, reduced sunlight can lead to lower levels of serotonin, a neurotransmitter linked to mood regulation. This is a major contributor to Seasonal Affective Disorder (SAD), a type of depression that occurs in darker months. As spring arrives, longer days and increased exposure to sunlight boost serotonin levels, leading to improved mood and energy.
Warmer temperatures also contribute to increased energy levels. Cold weather tends to keep people indoors, leading to reduced physical activity and possible lethargy. In contrast, spring’s milder temperatures encourage outdoor activities such as walking, jogging, or gardening, all of which have been shown to improve mood and overall well-being by increasing endorphin levels.
Beyond biological factors, there is also a psychological component to spring fever. The change in seasons often brings renewed optimism, with people setting new goals, engaging in social activities, and anticipating summer. The fresh start associated with spring can influence emotions, reinforcing the idea of spring fever
While "spring fever" may sound like a vague or romanticized idea, scientific evidence suggests that seasonal changes do affect mood, energy levels, and behavior. Increased sunlight, changes in hormone production, warmer temperatures, and psychological factors all play a role in why people often feel more energized and cheerful in the springtime. So, the next time you find yourself feeling a little more awake and motivated as the flowers bloom, you can thank both science and nature for the seasonal shift.
