In the midst of the Covid-19 pandemic, many people have taken several precautions to stay healthy. Washing your hands for 20 seconds and practicing social detachment, for example, are essential to prevent the spread of the virus. But other measures can also be taken to avoid getting sick.

It is also important to have a strong immune system that can fight germs that you may come into contact with. If you have noticed that you often get sick, feel tired, or have other uncomfortable symptoms that you cannot find, your immune system may be weakened.

What is low immunity?

The immune system is essentially the body’s defense mechanism. For this, it uses white blood cells, thymus, spleen, lymph nodes and tonsils. Its function is to protect us against pathogens such as viruses, bacteria or other microorganisms that cause disease. That is, it is to keep us as healthy as possible.

In most young, healthy people, the immune system can do this. But sometimes, it doesn’t work as well as it should, making individuals more susceptible to disease.

Immune cells (white blood cells) are constantly circulating in the body, through the bloodstream, in search of problems. Most of the time, these white blood cells do their job, looking for invaders and protecting the body from them.

However, many different diseases can affect the performance of white blood cells. Among them are chronic diseases, such as diabetes and cancer, as well as infections, such as HIV. Other conditions, including some autoimmune diseases, such as lupus or rheumatoid arthritis, can also weaken the immune system.

Certain medications, such as corticosteroids or chemotherapy drugs, used to fight inflammation in the body, can also lower immunity.

Although these drugs affect the immune system, they are prescribed because their benefits of fighting or controlling the disease outweigh any possible disadvantages. In addition, it is possible to supplement your diet while taking some of these medications, to prevent your immune system from suffering such a blow.

Watch out for the signs below to identify if your immunity is low.

1. Very high stress level

It is no accident that you tend to get sick after a big project at work. Or, after a stressful situation at home. Long-term stress ends up weakening your immune system’s response. That way, you are more likely to get diseases.

2. Constant colds

It is normal for adults to have two or three colds each year. Most people recover in seven to ten days. However, if you are constantly catching colds – or have a cold that will not go away – it is a clear sign that your immune system is weakened.

3. Frequent stomach problems

If you have diarrhea, gas or constipation frequently, it may be a sign that your immunity is compromised. After all, almost 70% of the immune system is located in the digestive tract. The beneficial bacteria and microorganisms that live there defend your gut from infections and support your immune system.

Low amounts of these beneficial intestinal bacteria can put you at risk for viruses, chronic inflammation and even autoimmune diseases.

4. Wounds that take time to heal

Human skin goes into harm reduction mode after a burn, cut or scratch. The body works to protect the wound by sending nutrient-rich blood to the wound to help regenerate new skin.

This healing process depends on healthy immune cells. However, if your immune system is sluggish, your skin is unable to regenerate at the normal rate. Instead, your wounds take time and have difficulty healing.

5. Frequent infections

If you seem to be fighting frequent infections, your immune system may be sending out warning signs. Signs of a possible immune deficiency in adults include:

  • Having more than four ear infections in a year.
  • Develop pneumonia twice in one year.
  • Suffer from chronic sinusitis or more than three episodes of bacterial sinusitis in one year.
  • You need more than two rounds of antibiotics in one year.

6. Constant tiredness

You know that if you work too hard and get too little sleep, you will end up feeling fatigued. However, if you are getting enough sleep and still feel exhausted, see if your body is trying to tell you something. When the immune system is compromised, your energy level becomes low. Because the body tries to save energy so that the immune system can fight germs.

In summary, if you experience one or more of these symptoms frequently, see your doctor.
