- Humans evolved on a planet with a 24-hour cycle of light and dark, and our bodies are set up to work in partnership with sunlight. One of the most obvious examples of this is the production of vitamin D in the skin in response to UVB exposure. This daily dose of vitamin D can help to strengthen our bones and teeth, but it also has an effect on our immune cells. Vitamin D enables the macrophages in our lungs – a first line of defence against respiratory infections – to spew out an antimicrobial peptide called cathelicidin, killing bacteria and viruses directly. It also tweaks the activity of other immune cells, such as B and T cells, which orchestrate longer-term responses. People with low levels of vitamin D are at greater risk of viral respiratory tract infections such as influenza.
- Doing everything you can to keep your immune system strong can feel like a lot of work. Committing to an exercise routine, good sleep habits, taking supplements, stress management and good nutrition is no small feat, but well worth your time and effort when it comes to staying well.

- Move Your Body. Movement is a key component of your overall health, including your immune system.

Get Enough Sleep... Getting enough of it is vital for a well-functioning immune system. Sleep seems to enhance a specific white blood cell response in the body, mainly the T cells, and this helps fight off infection in the body... Practice Mindfulness... stress suppresses your immune system... it’s been shown that meditation and mindfulness can improve one’s response to stress, and, in turn, promote immune function... Spend Time in Nature. We all know that going out in the sun and getting some of that Vitamin D is good for us. Being outside and in nature is also helpful for a variety of reasons beyond that... Vote I really believe voting is crucial to our health... failures of political leadership helped accelerate the early spread of coronavirus.

- We experience stress when the brain senses danger and triggers the “fight or flight” mode, preparing the muscles, heart and lungs to get you out of harm’s way. “Stress works to increase certain hormones, particularly cortisol, which ask the immune system to stand down so they can do the temporary job of addressing the existential threat,” explains Dr. Rachel Franklin... But when stress is chronic, it hurts immunity. “If allowed to circulate, stress hormones make the immune system sluggish when faced with a challenge,” Franklin says.
- Obesity increases inflammation. Chronic inflammation and chronic disease make the immune response less effective,” says Dr. Heidi Zapata... Smoking and heavy drinking are very harmful to immunity. “Excessive alcohol consumption that leads to liver issues will affect the immune system. In people with cirrhosis and liver disease, I’d in many ways consider them immunocompromised,”
“There’s nothing worse you could do for your immune system than smoke... While your immune system should be on patrol looking for something it needs to fight, you’ve instead sent it to your lungs, sinus passages, mouth and throat to fight the poison you just ingested. Your immune system can’t fight battles on multiple fronts and do it effectively,” Franklin says. Changing these habits are among the best immune boosters.
