Many people have heard older relatives suggest that aching joints can forecast incoming weather changes. But is there any truth to the notion that joint pain possesses predictive capabilities regarding impending weather shifts?
The Link Between Joint Pain and Weather Changes: Fact or Fiction?
A comprehensive study, involving millions of older adults, including those with rheumatoid arthritis, investigated the long-held belief that joint pain could predict weather occurrences like rain or snow.
A team of experts in the US published findings in the BMJ, ultimately determining that, based on their data, rainfall doesn’t significantly affect joint discomfort, although they remain open to the possibility of a connection.
While researchers conceded slight variations in reported joint pain on rainy days, they observed: “(The differences) were so small that they are unlikely to be clinically meaningful.”
The scientists didn’t completely refute the idea that aching knees might act as natural barometers: “No relation was found between rainfall and outpatient visits for joint or back pain. A relation may still exist, and therefore larger, more detailed data on disease severity and pain would be useful to support the validity of this commonly held belief.”

Examining Medical Claims Data
To probe the potential correlation between joint pain and meteorological conditions, the team scrutinized medical claims from the US Medicare system, encompassing over 1.5 million adults older than 65.
They scrutinized physician visits for joint or back pain over four years, from 2008 to 2012, totaling approximately 11.6 million appointments.
Scientists analyzed rainfall figures derived from US weather stations to discern patterns concerning how precipitation influences the number of individuals seeking medical advice for specific ailments and symptoms.
The analysis centered on patients diagnosed with osteoarthritis, spondylosis, intervertebral disc disorders, and other non-traumatic joint conditions.
They observed that during sustained precipitation, a 1mm increase in rainfall correlated with a 0.318% increase in outpatient consultations for joint discomfort.
Study Limitations and Future Research
On days when study participants attended their doctor’s appointments, there was a 0.04% increase in outpatient visits for joint pain when it wasn’t raining.
Researchers did acknowledge specific limitations in their study, particularly the absence of detailed data regarding the severity of the experienced pain.
This implies that a small number of individuals might pursue medical assistance on rainy days, yet their pain could be more intense, potentially indicating a link between weather conditions and pain severity.
Furthermore, they noted, “We lacked information on use of drugs during periods of pain exacerbation; patients could self manage symptoms by taking over-the-counter analgesics, which would not be detectable in our data.”
Key Takeaways:
- Rainfall has a limited impact on joint pain.
- More research is needed to understand the connection between weather and pain.
- Further studies should examine pain severity and medication use.
