The human immune system is a complex fortification wall that not only protects the human body from external threats like viruses, bacteria but also battles illness-causing events within the body. We bring you some interesting facts about the immune system.
While most of the immune cells reside in lymph nodes, every tissue in the human body has immune cells constantly looking out for any sign of attack. There are innumerous pathogens that constantly attack us, and immune cells act as expert detectors to tackle this threat!
White blood cells are the first line of defence-recognizing pathogens and fighting with them. Lymph nodes are known for the production and storage of infection-fighting cells throughout the body. Spleen cleans old and damaged blood cells and controls the quantity of blood in the human body. Isn’t it amazing?
Optimism in life can favourably affect the immunity. If you are positive in life and are happier, you will be less stressed and will eat right. Stress leads to an increase in the level of cortisol which can blunt your immune system badly.
Our body needs time to repair and heal itself to function properly without any illness. Insufficient sleep can weaken the immune system so much that you may even catch a common cold more easily. So, don’t miss that beauty sleep!
You know your body is doing its job if you have a fever, which is most unpleasant. When your body increases the temperature, and you have a fever, it is in action, releasing white blood cells and fighting off the pathogens from further multiplying. Remember, a fever is the body’s defence mechanism tool.
One of the reasons the human race has been able to sustain and thrive for such a long time is that it has an immune system that adapts when it encounters a new form of pathogen or a foreign substance. The body remembers how it encountered and defeated a foreign substance; hence next time it encounters it; the immune system can easily defeat the virus or bacteria!
The immune system is working hard to keep you safe, all you need to do to support it is eat well, sleep well and be physically active. Not much of an ask, right?
