Catching a cold or flu requires exposure to bacteria and viruses and a body with a weak immune system is unable to sufficiently protect it.
Scientifical studies show the correlation between body toxicity and impaired immune resistance to pathogens.
The main function of the lymphatic system is detoxification and disposal of metabolic waste. The compromised quality of the air, water, food, etc., causes significant accumulations of metabolic waste products in our body, some of which are toxic.
In many cases, this accumulation of toxins causes us to feel
low energy levels, fatigue, mood swings (the clinical symptoms of which are often confused with depression by physicians) fatigue etc.
There is no doubt that lymph drainage is a powerful method for lymphedema reduction, but it also is a detoxification program.
To lead a life toxins free is very difficult now days. It requires changing a diet, lifestyle and sometimes giving up on things we like the most. Toxins are everywhere even in the air we breath and the water we drink.
Have you ever heard the expression: "winter blues" often used in Europe to describe a seasonal depression, lethargy and fatigue due to the lack of sun exposure in the short day light winter days? That might be the truth, but what about toxins we breath in during a heating season? We turn on our gas heat, keep our windows closed and expose ourselves to combustion by-products from burning gas or fireplaces; that alone can result in flu-like symptoms by overloading the body with more toxins that the system can handle.
I personally see regular lymph drainage sessions incorporated with full-body stress management massage as no less important than immunisation against the flu virus and other infections. Immunisations sometimes do not protect people from contracting the flu, for example.
A consistent detoxification program has proven very effective in protecting humans from infections.
