9. Neglecting the Importance of Water

Proper hydration is essential for overall health as well as strong immunity. Without water, your body and immune system would not function properly.

Adequate water intake helps the immune system fight off infections. It also helps remove harmful toxins and waste products from your body. This helps your immune system better fight infections.


Low water intake can lead to dehydration, which impacts your immune system. According to a 2012 study published in Luminescence, dehydration results in immune system suppression.

Dehydration even affects your energy level and sleep quality, which can make you less likely to exercise, another trigger for a weakened immune system.

Any healthy person should drink at least eight 8-ounce glasses of water every day. However, water intake may depend upon the climate in which you live, how physically active you are, and your overall health.

10. Misuse of Antibiotics

Antibiotics are the keystone of modern medicine, but their misuse can generate unwanted side effects, such as stomach upset and diarrhea or even an allergic reaction.

Frequent and inappropriate use of antibiotics can harm the immune system, even your overall health.

First of all, it can lead to antibiotic resistance. This means that antibiotics that may have worked in the past will no longer work against bacteria or other microbes.

For treatment, you may need higher doses of medicine or stronger antibiotics, leading to more side effects.


Do not take antibiotics that were not prescribed specifically for you. If your doctor has prescribed antibiotics, make sure to complete the course. Always ask your doctor about the side effects.

Never take antibiotics for viral infections, as they do not work against viruses.
