Given how important your immune system is to your health, taking steps to protect your immune system can go a long way in keeping you healthy. If you have a compromised immune system, you can become very sick even if you are exposed to the type of infectious organisms that don’t normally cause serious harm.
It is important to learn how to avoid infections if you are immunocompetent, but even more so if you are immunocompromised.
Boosting Your Immune System
You can protect your immune system by adopting healthy lifestyle habits. There is no way to develop a better than normal immune system, so maintaining optimal function is the goal. Steps you can take to protect your immune system include:
Diet: Eat a diet high in fruits, vegetables, and lean protein. These foods provide you with the nutrients your body needs to produce immune proteins, enzymes, and cells. Smoking: Don’t start smoking, or make the effort to stop smoking if you smoke. Smoking interferes with the immune function of your respiratory system, predisposing you to infections. Stress: Manage stress. Excess stress can raise sympathetic hormone function, which directly reduces your immune function. Sleep: Get enough sleep each night. Sleep allows your body to maintain healthy homeostasis (consistency). Lack of restorative sleep interferes with healthy hormone balance, compromising your immune system. Infection prevention: Avoid excessive exposure to infectious pathogens. Be sure to get your recommended immunizations, especially if you work around sick people. Hygiene: Practice good hygiene, such as washing your hands regularly, especially before meals.
Are You Immunocompromised?
Having a compromised immune system (also called being immunosuppressed or immunocompromised) means that your body mounts a diminished immune response to invading organisms. A compromised immune system also makes you more susceptible to some types of cancer.
Causes
There are three types of immune deficiencies:
Primary immune deficiencies, with which people are bornAcquired immune deficiencies, which include diabetes, HIV, and certain blood disordersAutoimmune disease, which results from an overactive, inappropriately functioning immune system
A number of medications, particularly chemotherapy and steroids, can directly suppress your immune system. Older age is often associated with declining immunity as well.
Protection and Considerations
If you are immunocompromised, you need to take the same steps to protect your immune system as someone who is immunocompetent. But there are also a number of special considerations you should be aware of:
Food: Fresh fruits, vegetables, and seafood can harbor infectious agents that wouldn’t make an immunocompetent person sick, but can cause problems for someone who is immunosuppressed. Be sure to thoroughly cook these items. Immunizations: Some vaccines may not be as effective if you are immunocompromised. Your body may or may not respond fully to immunizations or even to your natural immunity from having had an infection earlier in life. Avoid germ-ridden settings: You may need to avoid settings and locations that are known for spreading infections, such as day care centers, hospitals, and nursing homes. Use a mask: Sometimes, wearing a mask or gloves can reduce your exposure to germs. Be sure to ask your doctor for a recommendation, and consider wearing a mask when you have to spend time on an airplane or go to your healthcare provider’s office or a hospital.
A Word From Verywell
Maintaining a strong immune system is vital to staying healthy. A lot of that is based on maintaining habits that protect your immune system. If you have a compromised immune system, you have to take extra steps to protect yourself from exposure to infection-causing germs.
