In a recent study of arthritis, researchers tried but failed to find any correlation between pain intensity and any of those features of the weather -- humidity, temperature swings, barometric pressure -- usually cited by arthritis sufferers as the cause of their increased pain  Those arthritis sufferers in the study who were convinced of the existence of such a correlation gave widely varying accounts of the time delay between the occurrence of what they believed to be the relevant feature of the weather and the increased intensity of the pain
Thus, this study
indicates that the weather affects some arthritis sufferers more quickly than it does other arthritis sufferers
