- Sitting too long increases various health risks such as cardiovascular disease, metabolic risks, musculoskeletal problems, and swelling.
- It is important to switch between "standing and sitting" frequently; simply standing for long periods does not solve the problem.
- Regular standing up using a timer, introduction of standing desks, increasing small movements conscious of NEAT (Non-Exercise Activity Thermogenesis), and reviewing chairs are effective.
- Workplace-wide initiatives (such as walking meetings) are also effective, and the key to continuation is to start with small changes without aiming for perfection.
Many people may have heard that "sitting too long is bad for your health." However, some may not fully understand what exactly is bad or what to do about it. Especially in modern society, where desk work is central, sitting time tends to be long. This time, we will introduce the health risks caused by sitting too long and specific measures that can be practiced starting today, based on our experience at the geefee editorial department.
The Reality of "Sitting Too Long" for Modern People
Globally, modern people tend to sit for very long periods. For example, there are reports that adults in Australia sit for an average of about 9 hours a day, and in Japan, an average of about 7 hours (International survey by Bauman et al.). Since this figure combines commuting, desk work, meals, and watching TV, many people may actually be sitting for surprisingly long hours. When we at the editorial department tallied it up, we often found ourselves sitting continuously without realizing it during long meetings and focused work.
Main Risks and Mechanisms Cause by Sitting Too Long
Increased Cardiovascular Disease and Metabolic Risks
It has been shown that prolonged sitting tends to decrease blood flow and metabolism, leading to insulin resistance and impaired blood sugar control. There are also studies showing that physical activity other than exercise (Non-Exercise Activity Thermogenesis: NEAT) is important for cardiovascular health, and epidemiological studies indicating that sedentary behavior increases the risk of heart disease and diabetes (reports by Ekblom-Bak et al., Warren et al., Hamburg et al.).
Musculoskeletal Problems and Swelling
Maintaining the same posture for long periods tends to cause poor posture and leads to neck, shoulder, and lower back pain. It is also known that blood and lymph flow tend to stagnate, leading to swelling and fatigue in the lower limbs (reports suggest that posture improvement and dynamic stimulation are effective).
Hacking Your Workplace: 4 Easy-to-Implement Measures
From here, we will introduce specific measures that are easy to incorporate into the workplace, focusing on methods that we have actually tried and felt effective.
1. Create a habit of standing up frequently (with a timer as your ally)
- Set a timer to stand up every Pomodoro (25 minutes of work + 5 minutes of break) or every 30 minutes. Short standing times and light stretches improve blood flow.
- When we tried it, incorporating "walking calls" where we stand and talk during phone calls or web conferences alone increased our concentration.
2. Utilize standing desks and height-adjustable desks
- It is said that it is good to increase the time spent working while standing by a total of about 1 to 2 hours a day, but standing continuously can be a burden, so it is ideal to alternate between sitting and standing.
- Height-adjustable desks make it easy to change posture and reduce the burden of long hours of work.
3. Increase "small movements" conscious of NEAT
- Small actions such as standing up to talk to colleagues, using stairs, and getting drinks accumulate and contribute to energy consumption. There are also reports that desk work consumes fewer calories compared to agricultural work (Levine et al.).
- Even performing light squats or calf raises (standing on tiptoes) a few times during work can reduce swelling and fatigue.
4. Review your chair and sitting posture (kneeling chairs and ergonomics)
- Adjusting the seat surface and tilt angle so that the back of the knees and hip joints are not constricted reduces the burden on the lower back. Consider kneeling chairs and "active seating" with movable seats.
- Also, repeating simple neck and shoulder stretches and chest-opening exercises for regular posture resets helps prevent poor posture.
Workplace-Wide Initiatives and Tips for Implementation
It is important not only to change individual behavior but also the workplace culture and systems. Initiatives such as incorporating standing meetings, encouraging short walks during lunchtime, and providing standing spaces lead to creating an environment where these practices can be sustained. At our workplace, when we tried "walking meetings once a week," we felt that discussions became more active and afternoon drowsiness decreased.
The key to introduction is "not aiming for perfection." Start with small changes (even standing for 5 minutes a day) and prioritize habit formation.
Summary
Sitting too long carries risks that affect the cardiovascular, metabolic, and musculoskeletal systems, and it is important to switch between "standing and sitting" frequently, not just standing. Combining measures such as standing up frequently with a timer, incorporating standing desks and dynamic chairs, increasing small movements conscious of NEAT, and promoting workplace-wide initiatives can naturally reduce daily sedentary time. We are also gradually adopting these and feeling the effects.
