The newest strain of coronavirus has managed to steer it’s way into almost every one of our daily lives and with it has brought multiple queries surrounding the subject of immunity, one major question being; ‘Can I strengthen my immune system?’.

Of course, there’s no way to remarkably strengthen your immune system but there are a selection of surefire ways that can help support your immune system, keep it in top shape and prepare it to do its job when needed.

Can You Strengthen Your Immune System?

The possibility of being able to strengthen your immune system is pretty appealing - especially if it means that you’ll be more capable of fighting off viruses or germs.

Unfortunately, it’s not that simple - there’s still so much research required to know more about what makes the immune system tick and there’s no overnight cure to improve it [1].

One tried and tested way to help support your immune system is quite simply by living a healthy lifestyle [2]. By making a few tweaks in your day to day life you could improve your immune system over time. These changes include:

  • Don’t smoke

Known to bring with it many complications, smoking is primarily responsible for compromising the balance of the immune system - this can increase the risk of autoimmune disorders and ultimately weaken your immune system [3].

  • Eat a diet high in fruit and vegetables

Though further research is needed, providing your body with certain foods might help keep your immune system strong [4]. That said, filling your diet with foods packed with healthy vitamins and minerals is always a good idea, as is monitoring your vitamin levels on a regular basis.

  • Exercise regularly

As many of us know, regular exercise brings with it plenty of positive effects - it can improve cardiovascular health, lower blood pressure and ultimately contributes to good health - including a healthy immune system [5].

  • Drink alcohol in moderation

Drinking alcohol in excessive amounts can weaken your immune system, making you more vulnerable to serious infections [6].

  • Manage your stress levels

In a series of studies undertaken by Carnegie Mellon University, a number of volunteers were exposed to the virus which causes the common cold and then quarantined for observation. It was found that those who reported less stress in their lives were less likely to develop symptoms of the common cold [7].
So, take time to relax during this frantic time - your immune system will thank you for it.

With proper intake of vitamins being an important part of maintaining a healthy immune system - it’s important to keep an eye on your vitamin levels and monitor them regularly.
