Prolonged inactivity can lead to various health consequences, including weight gain, muscle atrophy, and an increased risk of chronic diseases such as diabetes and cardiovascular issues. The body becomes less efficient at using glucose and fat for energy, impacting metabolic health. Mental health may also deteriorate, leading to feelings of anxiety and depression. Maintaining regular activity is essential to counteract these effects, as it improves muscle strength, enhances mood, and supports overall well-being, promoting a healthier lifestyle over time.
