It never fails, once one member of the family gets sick, everyone else is doomed.  Or are they? Have you ever noticed that sometimes Mom gets away Scott-free? It could be because she is constantly taking care of everyone and has someone built up a strong immunity. Or is it because she is a health nut and is constantly exercising and eating right? Your Immune system is complex, and many factors contribute to your individual immunity.

What does your Immune System do?

The function of your immune system is to defend your body against disease-causing microorganisms and prevent or limit infection. Your immune system gets alerted to unhealthy cells and is sent to address the problem. The more you are exposed to illnesses, the more your immune system is accustomed to fighting and defending your body. People with weakened immune systems are more susceptible to such diseases and infections.

How to boost your immune system

There are a few things you can do to decrease your chances of getting sick. Living a healthy lifestyle is a big factor in promoting a healthy immune system.

  • Do not smoke and only consume alcohol in moderation
  • Exercise 3-5 times a week, but make sure you don’t overdo it when you are sick
  • Embrace a healthy diet and foods high in antioxidants
  • Drink lots of water – it oxygenates your blood and flushes toxins
  • Minimize stress – if you read last week’s blog, you would know that stress has a direct impact on your immune system
  • Avoid infection – wash your hands and remember to wash your produce, as well as cook meats thoroughly


Keep in mind that as you age, naturally, your immunity declines with the decrease of t-cells your body has.  With these tips, you can give your body the best fighting chance to avoid illness. In addition, continue to get your flu shot every fall and beware of “immunity support” pills. Many of these have no evidence supporting that they boost immunity. If you are not feeling well take it easy, prevent the spread germs and seek urgent care to help evaluate and treat your symptoms. Our Urgent Care has several locations in St. Louis, St. Charles, and Franklin County. You can be seen every day of the week from 8 am – 8 pm.
