Exercising not only helps you with weight loss, but it also strengthens your immune system. People who exercise regularly rarely develop cold or flu.

Studies have concluded that regular exercise can mobilise the immune cells and help the body protect itself from cancerous cells and other pathogens.[5]

It is noteworthy that exercising too much can leave the body weak momentarily. This will affect the immune system making the body more susceptible to infections. Therefore, exercises should be done in moderation.

5. Distance yourself from stress

Too much stress will release an excessive amount of cortisol – a stress hormone. This will affect the immune system and can meddle with its flight or fight response.

boost immunity by meditating

To manage stress better, you can practice meditation or indulge in other engaging activities like joining a kickboxing class or art class. This will do good to your both mind and body.[6]

5. Taking supplements

As mentioned, certain vitamins like A, K, C, B6 etc are very vital for a healthy immune system and any vitamin deficiency can adversely affect your immunity. Therefore, if you fall sick often check if you have adequate levels of vitamins in your body.

Any deficiency, your doctor might suggest supplements and make dietary changes. This will improve immunity.[7]

6. Maintain hygiene

With Coronavirus turning pandemic, practising hygienic is indeed extremely important given the current scenario. In fact, health organisations like WHO and CDC have issued public notices on hygienic practices and recommend certain guidelines in order to prevent infections.

Cultivating simple practices like washing your hands often for 20 seconds thoroughly, disinfecting frequently used surfaces and covering your face while sneezing or coughing will prevent the spread of infections. These hygienic practices will also improve your immunity.


As much as you are eager about learning how to improve immunity, you should also be committed towards working for it. Remember, immunity cannot be strengthened overnight and a strong immunity is need of the hour to keep infections at bay.

Taking few precautions will also help you greatly in keeping yourself and your family safe from Coronavirus. For instance, avoid travelling of any sorts unless and until it is absolutely necessary. Similarly, if you are sick or have been in contact with someone who is sick, get yourself tested and self-quarantine for your own wellness and safety of others.

Apart from this, be hygienic always and communicate the same with your family, friends and peers. Awareness has helped people put an end to various epidemics in the past and it is the same with this novel Coronavirus too.

Stay healthy, stay safe!
