Open your eyes to sleep disorders
- Sleep is an essential part of life, a natural process with common rhythms that recharges our energy level and enables us to be vibrant and fully productive. Yet, this fundamental function is often compromised. Sleep disorders currently affect the lives of more than 18 million American adults, according to the National Sleep Foundation, creating a massive, invisible hurdle to health and productivity.
Non-REM and REM Sleep
Sleep is divided into two fundamental types that occur in cycles throughout the night: Non-Rapid Eye Movement (Non-REM) sleep and Rapid Eye Movement (REM) sleep.
Non-REM Sleep: This is the most prevalent and restorative type, accounting for approximately 80 percent of an adult’s night. It has four distinct stages, with two stages characterized as “deep sleep” (slow-wave sleep), which is crucial for physical rest and repair.
REM Sleep: This sleep is generally considered shallower and less restful than Non-REM sleep. It accounts for the remaining 20 percent of the night and occurs in cycles, typically once every 90 minutes.
The transition between these types forms the complete sleep architecture.
This phase is primarily when the body rests and recuperates. During the deeper stages of Non-REM sleep (slow-wave sleep), essential hormones are released that facilitate physical recovery, helping the body rebuild and counter the stresses accumulated throughout the day.
REM Sleep: Mental Processing and Dreaming
During REM (Rapid Eye Movement) sleep, the brain is highly active. The primary function here is mental processing, which includes consolidating memories and thoughts. This stage is also associated with vivid dreams. Critically, the body enters a state known as atonia—a temporary paralysis of limb muscles—which prevents us from acting out these dreams, ensuring physical safety.

How Much Sleep Do I Need?
Forget the standard recommendations—there is no single “normal” amount of sleep. While the adult average is often cited as 7.5 hours, individual needs can range from five to nine hours.
The key is to use daytime functioning as your ultimate guide.
If six hours leaves you feeling energized and alert all day, that is your ideal amount.
If you need nine hours to feel refreshed and productive, then that is your personal requirement.
When to Seek Professional Help
If you consistently struggle to fall asleep, or if you sleep a sufficient amount but still feel unrefreshed and sleepy during the day, you may have an organic sleep disorder requiring professional consultation.
One of the most prevalent disorders is sleep apnea, often characterized by loud snoring. When left untreated, the common form known as Obstructive Sleep Apnea (OSA) poses serious health risks, including increased chances of heart disease, congestive heart failure, and stroke.
