A sedentary lifestyle can lead to numerous negative health effects, such as increased risk of obesity, cardiovascular disease, diabetes, and certain cancers. Prolonged inactivity can weaken muscles and bones, diminish overall strength, and lead to poor mental health outcomes such as depression and anxiety. Additionally, sedentary behavior can disrupt metabolic functions, leading to imbalances in hormones that regulate appetite and energy use. Engaging in regular physical activity is essential to counter these effects and promote long-term health and wellness.
