10 Secret Things You Didn't Know Your Body Could Do

Remember when your grandparents told you that achy joints were an indication that a storm was coming? Spoiler alert: it's all true. When cold weather arrives, the atmospheric pressure drops, which increases the pain in the joints.

Robert Newlin Jamison, PhD, a professor in the departments of psychiatry and anaesthesiology at Harvard Medical School studied the effects of the weather on patients with chronic pain in San Diego, Nashville, Boston, and Worcester. He concluded that:

"Most of them reported that they could actually feel the changes even before the weather changed. In other words, they could feel some increased pain the day before the storm comes."

Of course, some people still argue that the connection between joint pain and the weather is nothing more than a myth but, truth be told, it's really hard to argue with the studies. Perhaps you'd better batten down the hatches the next time someone informs you of their aches and pains, because you know what it means.
