Seasonal changes can significantly impact physical activity levels due to variations in weather and daylight hours. For instance, colder months may discourage outdoor exercise, leading to a decline in overall activity. Conversely, warmer months often encourage outdoor sports and increased movement. Additionally, changes in seasonal routines, such as school schedules, may also affect exercise habits. Some individuals may experience seasonal affective disorder, further influencing motivation. Awareness of these factors can help plan and adapt fitness routines to maintain consistency and ensure continued well-being throughout the year.
