Can Sitting In Ac All Day Cause Joint Pain Orthopaedic Surgeon Explains Science Behind The Stiffness

. Mody, chairman and chief orthopaedic surgeon at Welcare Hospital, told us about the science behind it.

The problem is not directly with the air conditioner, but with how it makes you behave in air-conditioned spaces. “Air conditioning does not directly cause arthritis and bone degeneration. But prolonged sedentary indoor habits associated with excessive AC exposure seem to have worsened stiffness and muscle discomfort amongst individuals,” he explained.

In the air-conditioned spaces, people end up sitting for 8 to 10 hours in relaxed for poor postures, which can slowly trigger stiffness, muscle tightness and joint discomfort.

Why do older people report joint pain more in air-conditioned rooms? Dr Mody told us that ageing muscles and joints are naturally less resilient. Their reduced muscle mass, poorer circulation and underlying degenerative joint condition make it difficult for them to tolerate temperature variations.

There is a scientific reason why joints may be more vulnerable in cold indoor spaces, especially for those already dealing with certain joint-related problems. The surgeon explained that one may experience temporary tightening of the muscles, reduced flexibility, and slower circulation. This may be more observable in people who already suffer from pre-existing joint or pain-related conditions.

“People with osteoarthritis, cervical spondylosis, frozen shoulder, lower back pain or past injuries may experience increased discomfort during prolonged AC exposure,” Dr Mody mentioned the ailments which make one more vulnerable.

The surgeon further clarified that air conditioning does not directly weaken bones, cause osteoporosis or damage the skeletal system, as there is no scientific evidence to suggest this. The real concern is more indirect and may be linked to deficiencies and lifestyle habits. During summer, many people spend most of their time indoors, which means less movement, lower sunlight exposure and sometimes poorer hydration.

“Vitamin D deficiency remains highly prevalent among urban Indians who spend long hours indoors and don't get enough sunlight. Vitamin D is essential for healthy bones and calcium absorption; deficits can cause muscle weakness, fatigue, soreness in the bones, and, in severe cases, an increased risk of fracture," Dr Mody noted.

Many individuals ignore early warning signs until they develop into chronic problems. Persistent symptoms should not be dismissed as ‘just AC discomfort.’ Here are some of the signs Dr Mody highlighted:

Don't normalise them. The doctor believed they could indicate muscular strain, postural problems, early arthritis or Vitamin D deficiency.

The good news is that AC-related stiffness and muscle discomfort can be prevented with simple everyday lifestyle changes. Adjustments in temperature, seating, hydration and movement can help protect the joints and muscles if you spend long hours in cooled spaces. Here is a brief guide, as shared by the surgeon, regarding precautionary measures:
