Seasonal changes affect fitness habits significantly. In warmer months, people tend to engage in more outdoor activities such as running, cycling, or swimming, benefiting from increased sunlight and vitamin D exposure. Conversely, winter weather can limit outdoor exercise options, leading to decreased activity levels. Additionally, changes in mood and energy levels during different seasons can influence motivation; for example, seasonal affective disorder may lower enthusiasm during fall and winter months. Adapting fitness routines and goals seasonally can help individuals maintain consistent engagement in physical activity throughout the year.
