• The last decade has seen us evolve to a 24-hour society from a 12-to-14-hour society.
  • Lack of sleep affects personal social relationships, work output, school productivity and overall decision-making.
  • Factors including our use of technology and anxiety relating to COVID-19 can affect our sleep quality.

With the current coronavirus disease (COVID-19) pandemic, one of the recommendations by experts is social distancing and self-isolation when you experience symptoms. With the increase in travel restrictions and staying home, this is a good time to catch up on all the sleep lost as a result of our busy lifestyles.

We spend a third of our lives sleeping and sleep is meant to be good for us, but sleep disorders put our safety at risk, affect mental well-being and cost economies in lost productivity and healthcare.

The last decade has seen us evolve to a 24-hour society from a 12-to-14-hour society. The change from routine nine-to-five jobs to 24/7 work patterns has shifted our sleep. Social media screen time and the changing way we maintain our networks also affect our sleep. These new patterns can prevent us from functioning optimally day-to-day.

As you grow older, the amount of recommended sleep begins to decrease, but in our late teens 10 hours is still recommended.

Good quality, restorative sleep is essential for day-to-day functioning. Studies suggest that sleep quality rather than quantity has a greater impact on quality of life and daytime functioning. According to one study, 35% of people feel they do not get enough sleep, impacting both their physical and mental health. Insomnia affects between 30-45% of the adult population.

Sleep and COVID-19 anxiety

Sleep disorders cause significant individual and societal burdens and form a serious public health problem. Many people find falling asleep difficult thanks to staying up on their gadgets; in other cases, there is a challenge maintaining sleep.

Lack of sleep affects personal social relationships, work output, school productivity and overall decision-making. Screens, digital technology and the need to be connected electronically 24/7 cost many people to sleep 2-3 hours less than the minimum required amount.

COVID-19 and anxiety surrounding it can have a negative impact on an individual’s sleep pattern. The constant refreshing of social feeds contributes to a disturbed sleep pattern, worsening our ability to cope with this anxiety.

Screen time affects your brain’s circadian rhythm. The blue light on your phone lowers your sleep hormone called melatonin which instructs your brain to be wakeful at night. According to sleep specialists, this leads to a “late body clock” because the release of melatonin lags behind, leading to delayed sleep phasing and a form of “social jet lag”. This has a direct effect on an individual's mood, behaviour, memory and learning abilities. It affects a lot of body systems including weakening the immune system hence.

Can we retrain our brains to get to sleep earlier?

We can recondition our circadian rhythm to identify a “sleep cue” that the brain sees as a trigger for the initiation of sleep. As we adhere to the expert advice of social isolation we can utilize this time to recondition our sleep patterns which will help improve recovery. Practising what medical professionals call “sleep hygiene” can help too. This recommends basic steps that act as a pre-bedtime routine to help recondition your brain to improve the quality and quantity of sleep. The routines are easy to implement and if done on a daily recurrent cycle can help improve one’s sleep quality and quantity.

'A pillar of health'

Sleep plays a cardinal role in helping the planet by equipping all actors to make better decisions.

World Sleep Day on 13 March 2020 highlighted sleep’s importance as “a pillar of health, allowing for better decision making and cognitive understanding in even big issues, such as our planet.”

“This focus is purposefully broad in meaning, surrounding the message that quality of life can be improved with healthy sleep. Conversely, when sleep fails, health declines, decreasing quality of life. Sound sleep is a treasured function,” says a release from the World Sleep Society.

“If we really want to contribute to the planet’s survival, a wise activity is to extend the period of our sleep time,” adds Dr Liborio Parrino, Chair of the World Sleep Day Committee.

Increased sleep periods mean reduced consumption of fuel, electricity, food and oxygen (breathing is attenuated during sleep). Better quality sleep also reduces the risk of labour-related and road accidents, promotes the secretion of melatonin and protects the natural circadian clock, which can prevent premature ageing in humans.

Everyone reacts differently to stressful situations and the outbreak of coronavirus may be stressful for people and communities. It is important that we use self-care and self-compassion to promote our well-being. Sleep specialists recommend practising a sleep hygiene routine for an average of 2-6 weeks to notice an improvement in your sleep quality and quantity. Working from home and being virtually connected is positively possible thanks to the internet, but it has cons when it comes to health and well-being.
