Sleep. For so many, it’s an elusive dream. With the constant demands for more and more coming from every direction, people may compensate by taking less time for sleep. But this sleep-deprived state isn’t good for anyone and likely contributes to short and long-term health risks.
While producing the film, I was delighted to chat with Dr. Carmel Harrington, who has a Ph.D. in Sleep Medicine from Sydney University. Dr. Harrington has nearly 20 years of experience working in the world of sleep, and she is an internationally recognised sleep expert.
In our discussion, Dr. Harrington shared her fascinating knowledge about what really goes on when we sleep. We experience various states of sleep, including REM (rapid eye movement) and non-REM (NREM) sleep. During REM sleep, our brains are incredibly active. This is the time period in which we dream, and the brain does housekeeping that it can’t do when we are awake.
During slow wave sleep, NREM sleep, our brains get a respite and experience a slow-down. However, our bodies are busy, getting ready to take on another day. Leaders require good sleep for many reasons, including allowing our prefrontal cortex time to rest. When you are in a sleep-deprived state, your prefrontal cortex will not ignite, and you will essentially be not as smart. It’s easy to see how this can be detrimental to your leadership skills!
You need to have enough sleep so that when you wake, you can meet not only the challenges but the joys of the day.

It’s not enough to sleep so that you can ‘get through’ the next day. You need to sleep so that your brain and body are ready to face the challenges of the day, certainly. But, you also want to be rested so that you can enjoy all the lovely things in your life.
Fortunately, thanks to the efforts of researchers such as Dr. Harrington, there are many options for you if you have difficulties sleeping. There are over 70 sleep disorders that can potentially keep you from getting your beauty rest, and you shouldn’t hesitate to consult your doctor if you think your sleep is being impaired.
There are periods during your life when you may face sleep-deprivation. Infants, puppies, caring for family members and late-night deadlines can disrupt your sleep, or even make it impossible! However, these periods of time are typically transient and short-lived, and you still have options to try and get as much rest as possible. Please don’t be afraid to reach out to family, friends or medical personnel if you face long periods of sleep deprivation.
As a leader, you are expected to function at your optimum level. You need good sleep to properly function. If you are tired, you will be more likely to snap at others, to be short-tempered, and generally unpleasant. This type of behaviour doesn’t inspire creativity and innovation. So, take a hard look at your bed and think about how much sleep you genuinely are getting each night.
