When your immune system is functioning properly, it helps to protect your body against infection and disease. However, there are a number of things that can suppress your immune system, making you more susceptible to illness. Some of the most common things that suppress your immune system include:

Lack of Sleep

If you’re not getting enough sleep, your body will have a more challenging time fighting infections and diseases. Most people need between seven and eight hours of sleep each night.


Anxiety can be very taxing on your body and can lead to a weakened immune system. When you’re feeling anxious, your body produces stress hormones, which can suppress your immune system.


Smoking can suppress your immune system by damaging your lungs and respiratory system. It can also increase your risk of developing cancer.

Poor Diet

If you’re not eating a balanced diet, your immune system will be weaker. A poor diet can lead to deficiencies in vitamins and minerals, impairing your immune system’s function.


Stress can also suppress your immune system by releasing stress hormones that interfere with your immune system’s ability to fight off infection.

Excessive Alcohol Consumption

Excessive alcohol consumption can suppress your immune system by damaging your liver and interfering with your body’s ability to fight off infection.


As you age, your immune system becomes less efficient at fighting off infection. This is because your immune system’s ability to produce antibodies decreases with age.


If you’re already sick, your immune system will be working harder than normal to fight off the infection, which can lead to a weakened immune system.

Low Vitamin D

Vitamin D is essential for a strong immune system. It helps the body produce antibodies, which fight off infection. A lack of vitamin D can make you more susceptible to illness.

Certain Medications

Some medications can weaken your immune system. These include steroids, cancer treatments, and medications that suppress the immune system.

If you’re taking any of these medications, talk to your doctor about how to reduce your risk of getting sick.

Too Little Time Outdoors

We have evolved to be outdoors, but we now spend most of our time indoors, contributing to the rise of allergies, asthma, and seasonal affective disorder (SAD).

This means that we’re less likely to get exposed to germs and bacteria, which can help build up our immune system.

If you’re worried about your immune system, consider spending more time outdoors.

Too Much Time on Your Phone

Many of us check our phones when we wake up, keep them in our pockets all day, and use them in bed before we go to sleep.

This constant exposure to electronics can disrupt sleep, weakening your immune system.

Try to limit your phone use at night, and consider turning off notifications so that you’re not tempted to check your phone every time it buzzes.

To Sum Up

There are many things that can suppress your immune system, ranging from stress to a lack of sleep. It’s important to be aware of these factors so that you can take steps to avoid them. By keeping your immune system strong, you’ll be better able to fight off illnesses and keep your body healthy.
