World Sleep Day and the Workplace – 19 March 2021

February 2021

The World Sleep Society (WSS) celebrates World Sleep Day (WSD) on Friday, 19 March 2021. The slogan for the 14th annual World Sleep Day is Regular Sleep, Healthy Future.

WSD is a call to all sleep professionals to advocate and educate the world about the importance of sleep for achieving an optimal quality of life and improve global health. The focus on regular sleep for 2021 is based on the benefits that regular sleep offers.

Studies have demonstrated that stable bedtimes and rise times are associated with better sleep quality in young, middle-aged adults, and seniors. Regular sleepers have better mood, psychomotor performance, and academic achievement.

How can we have a regular sleep? WSS remind that we need to remember the two processes that regulate both the timing and length of sleep:

• Circadian regulation (process C) and homeostatic control (process S) also known as the two-process model of sleep. Although many other factors affect sleep, such as environment, stress, and medications; understanding these two processes will help us strive towards a consistent sleep schedule.
• Process C refers to our internal clock, regulated by a part of our brain called the suprachiasmatic nucleus (SCN) of the hypothalamus. This clock regulates and controls the 24-hour sleep-wake cycle via the influence of light and melatonin.
• In the absence of light (as during the evening hours) melatonin is produced promoting sleep but in the presence of light, the production of melatonin ceases, signalling our brain that is daytime and we need to wake up.
• Our behaviour can override these natural signals. For instance, bright lights at night shut down the production of melatonin, delaying sleep until late hours of the night.

The World Sleep Society recommends the following 10 steps to achieve healthy sleep:

1. Fix a bedtime and an awakening time.
2. If you are in the habit of taking a nap, do not exceed 45 minutes of daytime sleep.
3. Avoid excessive alcohol ingestion 4 hours before bedtime and do not smoke.
4. Avoid caffeine 6 hours before bedtime. This includes coffee, tea and many sodas, as well as chocolate.
5. Avoid heavy, spicy, or sugary foods 4 hours before bedtime. A light snack before bed is acceptable.
6. Exercise regularly, but not right before bed.
7. Use comfortable bedding.
8. Find a comfortable temperature setting for sleeping and keep the room well ventilated.
9. Block out all distracting noise and eliminate as much light as possible.
10. Reserve the bed for sleep and do not use the bed as an office, workroom or recreation room.

To participate in World Sleep Day, consider:

• Organising an event to create excitement and generate interest in World Sleep Day.
• Circulating the official press release with sleep experts and local media.
• Distributing sleep patient literature such as booklets, leaflets and newsletters.
• Spreading the word on social media about #WorldSleepDay.

We really need to think how sleep or lack of it affects our performance at our workplace.
