Can the bones of the human body really predict climate change?

The expression “feel in the bones” often refers to something we know intuitively. In more literal terms, the idea behind the phrase is often linked to weather forecasting. Or at least that's what some patients with weak joints say. But is the human body really capable of predicting climate change? Believe it or not, but modern medicine indicates that the answer is yes.

The first studies related to the subject took place in 1990, with a very simple project: four arthritis patients underwent pressure changes similar to those that occur when there is a change in climate. The disease is characterized by painful inflammation and stiffness in the joints. Three of the study participants actually felt more pain at the time the pressure was lower.

In 2007, a study of joint pain reports from over 200 patients, also with arthritis, found a pattern between climate change and increased pain. Other surveys, from 2011 and 2014, ended up finding similar results, realizing that some participants actually had greater sensitivity to time variations.

Although no one is sure how or why, studies show that weakened joints may actually be more sensitive to changes in atmospheric pressure. Still, some theories circulate around.

The first is linked to the idea that pressure drop causes the expansion of the joint lubricating fluid - which can cause inflammation in those with compromised joints. Another theory is that low blood pressure ends up revealing pains that have always been there, as the body's production of cortisol and adrenaline (natural pain suppressants) decrease when air pressure drops.

Although somewhat uncertain, most doctors agree that climate change can even affect some people with chronic joint pain. But it is worth testing whether the theory applies in practice before moving to a warmer climate location.
