Signs of a Weak Immune System and How To Support Your Immunity

Your immune system is integral in your body’s defense against viruses, bacteria, fungi, and toxins. By keeping these intruders from overtaking the body, your immune system keeps you safe and healthy.

Unfortunately, many people struggle with a weak immune system. Poor nutrition, alcohol consumption, smoking, and immune system disorders can cause a weakened immune system, leading to various symptoms. Here, we’ll discuss the key signs of a weak immune system and what you can do to support your immunity. 

Signs of a Weak Immune System

Frequent infections

One of the most common signs of a weak immune system is frequent infection. People with weak immune systems may get an above-normal number of colds each year, as well as infections including pneumonia, bronchitis, meningitis, and chronic sinusitis, as well as skin and ear infections. 

Slow wound healing

If you have a weakened immune system, you may notice that wounds — even small scrapes or cuts — take a while to heal. 


Feeling tired throughout the day despite getting plenty of sleep each night is an indicator of a weak immune system. This occurs because your body is attempting to save energy so that it can defend itself against germs. 

Gut sensitivity

Gut sensitivity with symptoms including gas, constipation, bloating, and indigestion can be a sign of a weak immune system. 

Improving Your Immunity 

Proper nutrition and hydration

Eating whole foods that are high in antioxidants, fiber, healthy fats, vitamins, and nutrients helps strengthen the immune system. Additionally, a diet that’s low in added sugars can support the overall health of your body, including the immune system. 

Stress management

High stress levels over a prolonged period cause inflammation and may lead to imbalances in the function of your immune cells. So by managing stress with techniques including meditation, yoga, and mindfulness, you can support the health of your immune system. 

Moderate exercise

Exercising (without overdoing it) can boost your immune system by easing inflammation. Moderate exercise can also support your immune cells’ ability to regenerate, leading to a stronger immune system.
