Get to Know Your Immune System with these 7 Quick Facts



Your immune system protects you from the bad guys that want to invade your body. It does so by spotting foreign invaders that want to cripple you with diseases. As your immune system is able to identify the attackers, it sends the cavalry, which in this case is the white blood cells, to eradicate said invaders.

But even your immune system can fail at its job if it’s not strong enough. It needs to be functioning normally without any issues. Hence, the stronger your immune system is, the less likely it is for you to get sick. It basically saves you from experiencing the worst days of your life.

That’s why it’s important that you know a thing or two about it. This way, you’ll know how to strengthen your immune system and protect yourself from bacteria, viruses, and parasites creeping around your body.

Below are 7 things about your immune system you should know about:

1. We need germs to sustain health

Ever wonder why the species of humans have survived for so long? It’s because our immune system adapts to multiple invaders. When the body comes about a foreign substance, the immune system does its job by attacking it and holding on to its information. In the case that the invader returns, the immune system remembers and knows precisely how to take action. One ideal example is the measles. It only affects us once.

2. The first vaccine ever made was for smallpox

Basically, a vaccine works by exposing you to small infection of an illness. This results to your body manufacturing antibodies to fight against said illness. English doctor Edward Jenner came across the invention of vaccination after immunizing an eight-year-old boy with the pus from cowpox lesions on a patient’s arm. Surprisingly, this gave the boy immunity to smallpox.

3. A happy relationship improves immunity

This is because positive moments experienced with your partner boost the production of feel-good hormones, the endorphins. These said hormones are the very same that can help enhance your immune system’s capacities to fight off diseases. Research also shows that a happy relationship helps people improve their life-spans, mainly because of their improved immune systems.

4. There are some people who are born with little to zero immunity

This condition is called severe combined immunodeficiency (SCID). It is also called “bubble boy disease”, which affects one in every 100,000 individuals. It’s a main case of immune deficiency that is heavily distinguished by a serious failing in both the T- & B-lymphocyte systems. Due to this, the first few months of life can be threatened with one or more severe infections, which may include pneumonia or meningitis.

5. Inadequate sleep negatively affects your immune system

However, studies show that lack of sleep stifles your immune system’s capacity for getting rid of infections by decreasing the propagation of T-cells, which is a kind of white blood cells. Even a single night of not getting enough sleep threatens your immune system as this results to reducing the production of your T-cells, the ones that kill infections for you. This is the reason why being sleep deprived make you susceptible to diseases.

6. Exercising can make you more susceptible to infections

Germs multiply with ease in gyms, especially if people don’t wipe the equipment after they’re done using them. To aggravate the scenario, when you exercise you body naturally secretes the hormones cortisol and adrenaline. And these hormones happen to be the ones that can momentarily reduce the efficacy of one’s immune system, which is why it’s easy to catch while working out, especially if there’s sanitation issue with the people using the equipment and facilities in a fitness center.

7. Filling your body with fruits and veggies can fortify your immune system

Fruits and green veggies are great for your immune system. Studies prove that those individuals who eat fruits and vegetables on a regular basis get sick less often, in contrast to those who don’t. This is because the nourishing components in fruits and vegetables strengthen your immune system, so that it’s more effective in warding off infections.
