Changes in the weather might have an impact on your immune system. What can we do to avoid becoming sick when on vacation in a different climate? To begin with, a distinction must be made: “A change in temperature does not cause you to become ill, but changes in meteorological conditions can predispose you to becoming ill.”
It’s getting close to the holiday season. If you’re planning a vacation in a colder area, you might be concerned that being exposed to such a drastic change in temperature will put you in danger of becoming ill.
It’s excellent news, though, because this isn’t the case.
The simple act of being exposed to chilly temperatures does not make you sick. This can only happen if you are exposed to bacteria or viruses. The bad news is that the change in humidity can weaken your immune system, making you more susceptible to bacteria and viruses and increasing your chances of becoming ill.
Why is this the case?
You’ve probably noticed that your skin becomes drier in colder weather. In a low-humidity environment, your eyes, lungs, and nasal mucous membranes all dry out, weakening your defences against bacteria and viruses. Viruses also have an easier time surviving and multiplying in cooler temperatures, increasing your chances of getting sick.
To add insult to injury, the chilly temperature breaks down the particles we cough or sneeze out of our noses and mouths, making them easier for others to ingest. This makes it easier for a virus to move from one person to the next. In places with increased humidity, however, these particles remain larger, limiting the risk of infection.
How to Reduce Your Chances of Getting Sick
Avoid getting sick by:
taking vitamin D supplements or eating vitamin D-rich foods such as fatty fish, mushrooms, and eggs; getting plenty of rest or sleep; staying hydrated; practising good hygiene by washing your hands regularly and sneezing or coughing into a clean tissue; avoiding sharing food, drinks, crockery, and utensils with people who have a cold or the flu; and getting a flu vaccine.
