We all lead busy lives. With long work hours and endless phone scrolling, it’s easy to wind down on the couch after a tiring day. But spending too much time sitting can hurt your health without you even realizing it. Over time, this sedentary lifestyle can increase the risk of serious illnesses, including certain cancers.
In an interview with HT Lifestyle, Dr. Fahad Afzal Shaikh, a consultant oncologist at Saifee Hospital in Mumbai, pointed out that while modern life offers convenience, it also poses health risks. Many of us are glued to our screens, whether at work or home. We walk less and rely more on cars, leading to minimal physical activity. This shift might seem harmless, but it carries significant health consequences.
Research has shown that sitting for long periods is linked to several types of cancers, including breast, colon, and prostate cancers. Alarmingly, this risk exists even if you exercise occasionally but spend most of your day seated.
Dr. Shaikh notes that a sedentary lifestyle affects our bodies in many harmful ways. It disrupts hormone balance, increases insulin resistance, and raises levels of chronic inflammation—all factors that can support cancer growth.
Interestingly, many think that occasional workouts can make up for a sedentary day. However, evidence suggests that a short burst of exercise can’t fully counteract the impacts of hours spent sitting. The real danger lies in long periods of stillness.
But the good news is that simple changes in our daily habits can help lower this risk. Regular movement throughout the day can be effective. Dr. Shaikh recommends:
- Standing up and moving for a few minutes every hour.
- Taking short walks after meals.
- Opting for stairs instead of elevators.
- Stretching or engaging in light activity during the day.
Health guidelines suggest 150 minutes of moderate exercise each week, but breaking up long sitting times is equally essential.
Adding to this conversation, Dr. Bhooshan Zade, a radiation oncologist from Ruby Hall Clinic, emphasizes that prolonged sitting poses real risks. He describes sitting as being similar to smoking in terms of health threats. This inactivity can push the body into a metabolic “standby” mode, where insulin levels rise. High insulin can promote cell growth and increase the risk of cancer.
Moreover, women who sit for long periods may experience higher estrogen levels, which correlates with increased risks for breast and endometrial cancers. Limited movement can also slow digestion, allowing harmful substances to linger in the colon.
Dr. Zade states that it doesn’t take intense workouts to mitigate these risks. Just moving a bit every half hour can help lower insulin spikes and keep large muscles active. Even a 10-minute walk after meals can improve blood sugar control much more effectively than longer workouts later in the day. Small changes, like parking further away or taking the stairs, can add up to reduce your cancer risk.
Even casual activities like pacing or climbing stairs matter. Keeping our bodies moving throughout the day, even in small ways, can make a big difference in our health.
