Obstructive sleep apnea (OSA) is a common condition in which breathing repeatedly stops or
becomes shallow during sleep because the airway becomes partially or completely blocked.

Snoring is extremely common and affects nearly 40% of adults, but is not always harmless.
While occasional snoring may simply be caused by congestion or sleep position, frequent or
loud snoring can sometimes indicate an underlying airway problem such as obstructive sleep
apnea.

Continuous Positive Airway Pressure (CPAP) therapy is one of the most
effective treatments for obstructive sleep apnea (OSA). For many
patients, CPAP significantly improves breathing during sleep and reduces
daytime fatigue.

Our bodies follow an internal biological clock known as the circadian
rhythm, which regulates when we feel awake and when we feel sleepy.
This internal clock is influenced primarily by light exposure, and it helps
coordinate many important functions including sleep, hormone release,
metabolism, and body temperature.

Insomnia is one of the most common sleep complaints. It is estimated that
up to one-third of adults experience symptoms of insomnia, including
difficulty falling asleep, difficulty staying asleep, or waking too early in the
morning.

Narcolepsy is a neurological sleep disorder that affects the brain’s ability to regulate the sleep–wake cycle. People with narcolepsy may feel overwhelmingly sleepy during the day and may fall asleep unexpectedly, even after a full night of sleep.
