Your immune system is the body’s first line of defence against any dangerous pathogens or bacteria that have entered your body. Without your immune system these pathogens would spread around your body quite rapidly making you ill. It is therefore, one of the most important parts of the body’s protective system, making it integral to keep it working at an optimal level.
There are however, many things that can affect your immune system and that stop it from working as well as it should, such as aging (your immune system naturally declines as you grow older), mental and physical stresses, and environmental factors. As well as this, your immune system can also be weakened by exposure to various types of radiation such as x-ray, UV, gamma and cosmic rays, especially when flying long distances, an unhealthy lifestyle, bad eating habits, existing illnesses and certain treatments for illnesses. By looking at these factors, it is apparent that some of them are unavoidable, however it is important to realise that they do play a big part in our wellbeing, so making healthy choices is imperative!
Sometimes however, it is not a weak immune system that is the problem, instead it can be an imbalance in the immune system that causes the body to overreact. This imbalance in the immune system is the source of allergic reactions. When an allergen enters the body, the immune system acts as if it was a dangerous pathogen, overreacting and trying to destroy it by producing lots of antibodies. The overproduction of antibodies thus leads to a tightening of muscles, sneezing and itching, all traits that we have come to recognise as an allergic reaction.
Thus, both a weakened and imbalanced immune system can cause the body to act in dramatic ways, leading to illness and physical reactions. However living a healthy life can help these effects on the immune system. Positive changes include eating healthily, exercising more and avoiding long distance flights. Beta Glucan also helps by activating the immune system helping it to work at an optimal level, avoiding imbalances and weaknesses that could result in you getting sick.
