Do you notice you get sick more often during times when your sleep is suffering?
That’s because your sleep quality is directly related to your overall immune health.
Good sleep leads to a strong immune system, and vice versa.
This article will talk about how sleep can specifically impact immunity, the importance of getting a good night’s sleep, and ways to improve your sleep habits.
How Sleep Can Impact Your Immune System
Cytokines are proteins in our body that target inflammation and fights infection.
While we’re sleeping, our bodies make and release cytokines to protect us.
Therefore, when we don’t get adequate sleep at night, we make fewer cytokines. This may impact how well our body can fight off an illness.
Additionally, research has found a lack of sleep at night, or disturbances in sleep, are strongly linked to increased levels of inflammation.
Numerous studies with healthy participants subjected to sleep restrictions demonstrated changes in cytokines.
When we have more inflammation in the body (from lack of sleep), our immune system can be impacted in a negative way (1).
Lastly, a small study found looking at the impact of a lack of sleep, found that disturbances in sleep causes the same reaction in the body as shown when exposed to stress.
Ultimately, numerous studies have found an association between sleep and the immune system.
To support your immunity, it’s important to focus on getting good quality sleep each night.
A relaxing environment can go a long way towards boosting your sleep quality.
The Importance of Sleep

Along with supporting the immune system, sleep impacts our health in several other ways. Those include (7):
So not only is sleep important for supporting the immune system, but it’s also important for other key areas of our health as well.
Why People Don’t Get Enough Sleep
According to the Centers for Disease Control and Prevention, more than one-third of Americans don’t get the recommended 7-8 hours of quality sleep each night (8).
For some people, it’s a busy schedule or stress that gets in the way of a good night’s sleep.
Other reasons could be caffeine intake, brain activating LED lights, or children waking up at night.
Whatever the reason may be, if you’re struggling with getting good sleep at night it’s important to address the cause of the problem and find potential ways to resolve it.
