Frequently Asked Sleep Questions

October 02, 2013

[Part One of a Two Part Series]

We’ve had a number of questions asked in our Bed King stores regarding sleep and why it is important to our daily health. To help both our store staff and you our valued customers, we have put together a frequently asked questions (FAQ) blog post relating to sleep that will hopefully shed some light on what sleep is, why we need it and how it is thought to work.

FAQ 1: How Many Different Stages of Sleep Are There? 
Answer: There are five distinctive stages of sleep which are divided into two categories. The first four stages of sleep see the muscles of the eyes are relaxing and are referred to as the nonrapid eye movement (nonREM) sleep stages. The fifth and final stage of sleep is called rapid eye movement sleep or REM sleep and is characterised by active eye movement.

FAQ 2: What is the Most Common Sleep Disorder?
Answer: Insomnia is without a doubt the most common sleep disorder in South Africa. It is believed to affect at least a third of adults at some point in their life. It is defined by an inadequate or poor-quality sleep brought on by a difficulty falling asleep; waking up frequently during the night and not been able to return to sleep; waking up too early in the morning or unrefreshing sleep. This results in tiredness, a lack of energy, difficulty concentrating, and irritability.

Please Note! Insomnia is not simply defined by the number of hours of sleep a person gets or how long it takes to fall asleep. If you think that you are suffering from insomnia, please speak to your local medical practitioner.  

FAQ 3: What are the Symptoms of Sleep Deprivation?
Answer: There are a number of sleep deprivation symptoms, but the most drastic are weight gain and poor hand-eye coordination are possible symptoms of sleep deprivation. These can create issue with work and health. 

Did you know? Sleep-deprived people who were tested on a driving simulator perform as badly (and sometimes even worse) as people who are intoxicated. 

FAQ 4: What is a Circadian Rhythm?
Answer: A circadian rhythm is a 20th century reference to a 24-hour period of time and refers to events occurring within a 24-hour period. Circadian rhythmicity is a fundamental property possessed by all earthly organisms and is driven by an internal time-keeping system
