Simple 30:15 Sit-Stand Rule Helps Reduce Back Pain More Than Custom Plans

A new study from Australia shows that a very simple routine can help office workers reduce back pain. The rule is easy: sit for 30 minutes and then stand for 15 minutes. This 30:15 pattern helped people more than making their own personal sit-stand schedules.

The study was published in Applied Ergonomics. It followed 56 office workers for three months. All of them used sit-stand desks and already had lower back pain. Half of the workers followed the fixed 30:15 rule. The other half made their own plans with help from a physiotherapist.

The results were clear. The 30:15 group had a bigger drop in back pain. Their worst pain each day went down by 1.33 points on a scale of 10. Their average pain went down by 0.83 points.
But in the personalized group, the worst pain dropped only 0.69 points, and average pain stayed almost the same.

Workers who used the fixed schedule also said they felt more focused and less stressed. They followed the rule more regularly too. About 72% of them kept the pattern at least five times a day. Only 29% of the personalized group did the same.

Why did the 30:15 rule work better?
Experts say personalized plans sound helpful, but they can be confusing. Many people chose long sitting or standing times, like sitting for more than two hours or standing for 45 minutes. This did not help their back pain.

The personalized group even stood 72 minutes more each day, but this extra standing did not reduce pain. The fixed routine worked better because workers did not have to think or decide anything. They just followed the simple pattern.

The 30:15 ratio also fits the body’s comfort. Sitting for more than 30 minutes is considered too long, while standing for more than 15 minutes can cause strain. This balance also suits normal office work like emails or short talks.

The study also found that frequent position changes did not reduce productivity. Both groups felt less neck pain and tried to avoid long sitting periods. Still, after three months, fewer people kept up the routine, especially those working from home without proper desks.

This research shows that a simple routine may help more than a flexible one. For people who sit for long hours, the 30:15 sit-stand rule can be an easy and helpful way to lower back pain and stress.
