The old wives’ tale about catch­ing a cold if you get wet and shiv­ery seems to have some ba­sis in fact. When you feel cold, blood is di­rected away from your ex­trem­i­ties, so there’s less blood flow to the lin­ing of your nose. This re­duces lo­cal im­mu­nity, so res­pi­ra­tory in­fec­tions meet less re­sis­tance, which can triple your chance of de­vel­op­ing symp­toms when ex­posed to a virus.
