Sitting disease describes a sedentary lifestyle—a common habit of minimal movement that many people have adopted today. Although it’s not an official medical diagnosis, numerous studies have shown that prolonged sitting without regular physical activity can lead to significant health concerns.
What is Sitting Disease?
Sitting disease refers to health issues resulting from a predominantly inactive lifestyle. Researchers explain that extended periods of sitting can slow down the body’s metabolism, raising the risk of various chronic illnesses.
Those who sit for long hours each day are at a higher risk of developing obesity, heart disease, type 2 diabetes, and certain cancers.
Sitting disease is especially prevalent among people who spend much of their time seated at work or at home. While sitting itself isn’t inherently harmful, prolonged sitting without frequent movement can elevate the risk of severe health issues.
Health Impacts of Sitting Disease
Sitting disease can negatively affect health in several ways, including:
Obesity
Extended sitting reduces calorie burning, as the body’s metabolic rate drops when seated compared to standing or active movement.
Over time, if prolonged sitting continues unchecked, body fat may accumulate, contributing to weight gain and obesity.
Heart Disease
A sedentary lifestyle with long periods of sitting can decrease blood circulation and hinder fat metabolism, both of which increase the risk of heart disease. Studies indicate that individuals who sit for more than eight hours daily are at a higher risk of developing coronary heart disease compared to those who move regularly.
Prolonged sitting can also elevate LDL (bad cholesterol) and reduce HDL (good cholesterol), negatively impacting cardiovascular health.
Type 2 Diabetes
Sitting too long affects the body’s insulin sensitivity, making it less effective at processing blood sugar. This increased resistance to insulin heightens the risk of developing type 2 diabetes.
Posture Issues and Back Pain
Sitting for extended periods, especially with poor posture, can lead to musculoskeletal problems such as back, neck, and shoulder pain. Poor sitting posture may put extra strain on the spine and muscles, potentially leading to chronic discomfort.
Increased Risks of Cancer
Studies suggest that prolonged sitting may increase the risk of specific cancers, including colon and breast cancer. While the exact link is still being researched, increased inflammation and metabolic disturbances are believed to contribute to cancer risk in those with sedentary lifestyles.
Incorporating simple lifestyle changes can help counteract the negative effects of sitting disease. Adding physical activity to daily routines is essential for preventing and reducing its health risks.
