When the temperature fluxes from warm to freezing cold, your body becomes susceptible to airborne viruses floating around! During a wintery cold snap, humidity levels drop, causing airborne viruses to shrink. This dry atmosphere is ideal! It enables them to hang around in the air longer and even travel greater distances.
What Happens When Your Body Catches a Cold?
When you catch a cold, your body automatically triggers a response to protect itself. Immune cells and chemicals are fighting their way to get ahead of the virus — it’s attempting to minimize its ability to spread, by lowering the rate the virus is reproducing.
When you feel like you’ve been knocked down, that’s your immune cells working! Your blood vessels dilate —clearing the pathway for your immune cells to get to the infected area. This causes swelling and even raising your temperature.
