Support your immune system by securing sleep quality with Sibelius™: Chamomile

How does sleep affect immunity?

Sleep provides essential support to the immune system. Getting sufficient hours of high-quality sleep enables a well-balanced immune defense that features strong innate and adaptive immunity, efficient response to vaccines, and less severe allergic reactions. Studies indicate that sleep plays a crucial role in the robustness of our immune system. In fact, sleep contributes to both innate and adaptive immunity. In addition, researchers have found that during nightly sleep, certain components of the immune system rev up. For example, there is an increased production of cytokines associated with inflammation. This activity appears to be driven by both sleep and the circadian clock, which is the body’s 24-hour internal clock. 1

There is an association between short sleep duration and infection risk.2 Just one night of total sleep deprivation can decrease key immune cell function.3 At the same time, prolonged sleep curtailment and the accompanying stress response can lead to immunodeficiency.4 Lack of sleep is directly linked to decreased immune cells and overall immune cell activity.5

According to the National Heart, Lung, and Blood Institute, approximately 50 to 70 million Americans are dealing with sleep disorders, and 1 in 3 do not regularly get the recommended amount of uninterrupted sleep they need to protect their health.6 On top of that, a recent study in the UK from the University of Southampton showed that the number of people suffering from sleep problems rose from 16% to 25% during the Covid-19 pandemic.7
