Cold Air hurts my TMJ
Understanding Why Air Conditioning, Cold Drafts, and Temperature Changes Can Trigger TMJ Pain and Arthritis Symptoms
When the TMJ is already inflamed or arthritic, the surrounding nerves and tissues may become more sensitive to temperature changes. Cold air from air conditioning can therefore trigger discomfort or worsen existing jaw pain, even without chewing or moving the jaw.
Three possible mechanisms
1. Muscle response to cold: Cold exposure can increase protective muscle tension and aggravate existing myofascial pain involving the masseter, temporalis, and cervical muscles.
2. Joint pain sensitivity: In an already inflamed or arthritic TMJ, temperature changes may increase pain sensitivity through peripheral sensory nerve pathways. This does not necessarily mean the arthritis itself is worsening.
3. Cold-triggered pain amplification: Patients with chronic TMD may have heightened pain processing. Cold stimulation can become more uncomfortable even when it would not ordinarily provoke significant pain in a healthy individual.

Temperature-sensitive TMD patients have more arthritic changes
Study of 119 TMD patients, comparing 50 sensitive to sudden temperature drops with 69 who were not.
2016
TMD patients demonstrate increased cold-pain sensitivity
In a controlled study of 20 TMD patients and 20 healthy controls, TMD patients experienced pain at warmer temperatures during cold stimulation, including over the masseter and cervical regions.
A nationwide study in Scientific Reports investigated temperature, seasonal variation, and TMD prevalence. It supports an association between environmental temperature changes and TMD patterns, although it cannot establish that cold directly causes TMJ arthritis or individual pain episodes.
