If you experience it, the ability to fight bacteria, viruses and foreign objects that cause the disease decreases.

As widely known, if the immune system is weak, the body is unable to defend itself from various health threats. This condition is caused by various factors, including daily habits.

Here are a number of causes of a weakened immune system that must be known:

1. Stress can weaken immunity

It's no secret that almost everyone has felt the effects of stress at some point in their life. Headaches, chest pains, anxiety and feelings of tension are all symptoms of stress.

All of these factors combine causes the immune system to have to work harder to defend the body against health threats. So, if you experience stress, it's better to overcome it accordingly.

2. Less active

A weak immune system can be caused by being less active or not exercising. A study shows that regular exercise can help the function of neutrophils, which are a type of white blood cell that kills unwanted microorganisms and can sometimes be harmful to health.

3. Lack of sleep

Lack of sleep is one of the things that can interfere with health. Because, actually when the body is sleeping, the cells in the blood will work against the disease. Therefore, lack of sleep can cause the body to be unable to work effectively in fighting infections or disease germs.

Therefore, make sure you sleep enough so that the cells in the body will be able to work effectively against disease. For adults, it is recommended to sleep for 7-8 hours each night.

4. Not drinking enough water

The human body is mostly composed of water components, therefore every tissue and organ in the body will depend on it. Water will help carry nutrients and minerals to the cells and keep the mouth, nose and throat moist, also to prevent illness. The body will experience fluid loss through urination, defecation, breathing and sweating. Therefore, make sure that you consume enough water so that you can avoid weak immunity.

5. Lack of Intake of Nutritious Foods

This is the reason why consuming a balanced nutritious diet is something that must be done every day. Because if one of the nutrients is not fulfilled, then the immune system will weaken. Foods that can keep the immune system awake include fruits, vegetables and whole grain sources which help support the immune system by providing vitamins, minerals, phytochemicals, and most importantly, antioxidants.

In addition, you must also avoid certain types of food such as those that contain fat or oily because the saturated fat in them can make the immune system weak.

So, if you are a person who has a fairly busy schedule, you can also work around this by taking food supplements that contain vitamins and minerals.
