The COVID-19 pandemic has dramatically altered our lives. The disruptions to our economy and daily routines have been nothing short of overwhelming, affecting how we work, travel, and even sleep. With many educational activities halted, it's hard to deny the level of stress that the pandemic has introduced into our lives. This stress can have lingering effects, particularly on our sleep. Research indicates that the psychological consequences of the pandemic have activated stress systems, impacting various physiological functions, including sleep regulation through the hypothalamic-pituitary-adrenal axis [1]. Let's dive into how the COVID-19 pandemic has influenced your sleep patterns.
1) Prolonged Screen Time
Studies indicate that increased screen time can significantly reduce sleep duration. The blue light emitted from screens interferes with melatonin production, the hormone responsible for regulating our sleep-wake cycles. Since the pandemic began, many of us have been glued to our devices for news updates or binge-watching shows to escape stress. This increase in screen time, especially before bedtime, is likely contributing to our ongoing sleep deprivation. A study highlighted that healthcare workers experienced significant changes in sleep patterns during the pandemic, attributed in part to increased screen time related to work and information consumption [2].
2) Increased Stress
The toll of stress on mental health has been heavy. Concerns about school closures, working from home, and homeschooling can create an overwhelming sense of uncertainty about the future. The higher your stress levels, the more cortisol, the stress hormone, your body produces. This can keep you awake at night and lead to further sleep deprivation. Research has shown that perceived stress is closely linked to sleep quality, with anxiety and depression symptoms acting as mediators during the pandemic [3].
3) Isolation and Disruption in Daily Activities
With national lockdowns, quarantines, and social distancing, many people have found themselves separated from loved ones. Being confined at home can trigger stress and lead to various sleep issues. Working remotely can blur the lines between work time and relaxation time, causing disruptions to our daily routines. Consequently, our natural sleep-wake cycles are thrown off, forcing us to go to bed and wake up at irregular times. Research indicates that such disruptions have been particularly pronounced among individuals with chronic health conditions, further exacerbating sleep issues [4].
4) Unhealthy Habits
During these uncertain times, many are consuming more alcohol than usual as a way to cope with stress and boredom. However, alcohol can disrupt your sleep cycle, causing you to wake up multiple times during the night and further hindering restful sleep. Studies have shown that pandemic-related stressors have led to increased unhealthy coping mechanisms, including substance use, which can significantly affect sleep quality [5].
While sleep issues are common, the added stress and uncertainty from the pandemic have intensified them. The situation may feel overwhelming right now, but it's important to remember that things will improve in time. Coping with stress, fear, and anxiety is crucial, and following health guidelines like regular handwashing, wearing masks, and practicing social distancing can help us all move toward recovery more effectively.
