Worldwide, the lives of the people, and their physical and mental well-being, are affected by the pandemic. The impact of COVID-19 has led to altered sleep patterns, especially to our healthcare professionals and other frontliners.
Sleep is important because it helps maintain overall occupational performance and overall well-being. It’s vital as well to understand the significance of sleep and the immune response during a pandemic. Sleep is one of the most important prophylactics to keep people’s physical and mental state during the pandemic.
STAGES OF SLEEP
There are two major stages of sleep:
- Rapid eye movement (REM) sleep – the brain becomes active, the eyes move fast, dreams are happening, and the body becomes relaxed and immobilized.
- Non-rapid eye movement (NREM) sleep – has 3 stages of increased sleep depth (N1, N2, and N3). Each stage has different functions and effects on sleep.

IMPORTANCE OF SLEEP DURING PANDEMIC
- Enhances mood

Sleep is a public health and safety issue for healthcare professionals. Having poor sleep may be linked to mental health and physical health issues related to anxiety and stress. Sleep is also an occupational health threat for healthcare professionals because some are already fatigued and overworked due to the COVID-19 pandemic.
SLEEP AND IMMUNE FUNCTION
Between sleep and the immune system, there’s a bidirectional link. The immune system’s activation changes to sleep and the adaptive and innate immune systems are affected by sleep. It depends on the time and magnitude of an inflammatory response that is stimulated by the immune system. Wherein sleep can be increased in intensity and duration but also disturbed. If we have an infection, it makes us tired and increases the need to sleep. Sleep is frequently commended as being ‘the best medicine.’ It has been made known that persistent lack of sleep makes the immune system of the body weak. It also reduces its risk to certain infections, especially colds. There is proof that sleep improves the function of the immune and helps the body to heal.
