When we talk about health, we all have our own personal army that serves as our defenders in our war against foreign invaders, that have the potential to wreak havoc to our health. This personal army is better known as the immune system.

Our immune system carries out its life-saving duties without any conscious effort from us. However, to perform its essential role efficiently, it does need some support. More to the point, it requires that our actions do not undermine its ability to function at its best.

If we don’t treat our bodies well, our immune system ability to function will be less than optimal, making us more vulnerable to the attacks of pathogens and disease-causing microbes. The following is a list of signs that your immune system is struggling and needs some boosting.


Being exposed to cold weather should not make you sick. But, there is a huge possibility that you will be able to pick up some colds or flu from the people around you if your immune system is not functioning at its best. If you find yourself frequently catching colds or flu then your immune system certainly needs a boost.

Normally, adults can experience colds two to three times every season, with the worst of the symptoms lasting for only up to 4 days.  If your colds persist for a week or more then it is time to review your diet and stress levels.

Consult your physician if you need outside help to deal with symptoms, and discuss ways to help prevent re-infection.


Allergic attacks do happen and can change depending on the season.  If your allergic attacks become frequent and extreme then this could be a tell-tale sign that your immune system is not coping.

If your allergic reactions are triggered by things that did not normally cause you that response before, this may mean it is high time to give your immune system some strengthening.

Cold Sores

Some skin diseases that can signal a weakened immune system include candida, thrush, ring worm and tinea. Fungal infections can easily penetrate through your bloodstream if your body’s defenses have become severely weakened. Cold sores, fungal infections and other systemic illnesses are just few of the many diseases that affect people whose health have been compromised by medications that are used for treating other serious illnesses.

Weight Gain

Gaining weight can have adverse effects on your vital organs such as the heart. Weight gain can also be equally dangerous to your immune system. The more you gain weight, the more likely it will be for your body to reduce its ability to fight against infections. Weight gain can also lead to hormonal imbalances that will make it even more difficult for your immune system to defend your body against infection.


Another sign that your immune system is not functioning fully is when you always find yourself feeling constantly stressed out. Unfortunately, when stress is accompanied by viruses such as the flu your symptoms may even become worse. 

For us to succumb to an illness such as a viral attack, two conditions must exist. First is the causative pathogen, second is an environment that allows that pathogen to live and multiply. As it hard to avoid the first in many cases, it is important to maintain a healthy and strong immune system, to prevent your body being an environment conducive to attack.

A healthy diet, coupled with regular exercise and limited indulgence in harmful inputs are just few of the many ways to keep your immune system running as it should. Look after your immune system so it can look after you.
