Serious Diseases Caused by a Sedentary Lifestyle

A sedentary lifestyle, characterized by spending long periods sitting, has been linked to various serious diseases that affect both physical and mental health. Recent research from neurologists in the United States indicates that people who remain seated for extended periods have a higher risk of developing conditions such as dementia, stroke, anxiety, depression, and sleep disorders. These findings will be presented at the Annual Meeting of the American Academy of Neurology, scheduled for April 5-9, 2025, in San Diego and online.

Dementia and Cognitive Decline

Physical inactivity can lead to the deterioration of nerve fibers, increasing the risk of memory and cognitive problems. This decline is associated with thinning of the medial temporal lobe, a crucial brain area for memory functions. Additionally, lack of physical activity can cause a reduction in cerebral blood flow, raising the risk of dementia and other neurodegenerative diseases.

Stroke

A sedentary lifestyle is a significant risk factor for cardiovascular diseases, including stroke. Inactivity contributes to high blood pressure and atherosclerosis, conditions that can precede a stroke. In Mexico, it is estimated that 188 out of every 100,000 people suffer a stroke annually, and 90% of these cases could be prevented by modifying risk factors such as a sedentary lifestyle.

Anxiety and Depression

Lack of physical activity is directly linked to increased feelings of depression and anxiety. Regular exercise promotes the release of endorphins and other neurotransmitters that improve mood, while inactivity can lead to chemical imbalances in the brain, making individuals more prone to mental health disorders.

Sleep Disorders

A sedentary lifestyle can negatively impact sleep quality. Regular physical activity helps regulate sleep-wake cycles and improves sleep efficiency. Conversely, inactivity can contribute to insomnia and sleep apnea, both of which increase the risk of cognitive decline and cardiovascular diseases.

Conclusion

Adopting an active lifestyle is essential to preventing a wide range of serious diseases associated with sedentary behavior. Incorporating moderate to intense physical activity into daily routines not only improves physical health but also protects mental and cognitive well-being. Recognizing the risks of spending too much time sitting and taking proactive steps to reduce sedentary behavior in everyday life is crucial for long-term health.
