Sleep is a great protector of your immune system; it fights against infection and, if you do happen to fall ill, sleep is deployed to encourage rest and recuperation. On the other hand, it doesn’t take many nights of short sleeping to weaken your immune resilience.
Sleep is therefore a simple way to support the immune system in its fight against colds, flu, and other respiratory infections. This is supported by decades of scientific research, suggesting that sleep may be a powerful ally in the battle against the pandemic, and not only by reducing the likelihood or severity of infections. Sleep may also boost the effectiveness of any COVID-19 vaccines (when they become available), and studies are well underway investigating the health defences we gain against the Coronavirus by getting some decent shut eye.
