Sleep Disorders
Sleep is vital to our physical, mental, and emotional health, but sleep disorders can disrupt the restorative processes your body relies on. Understanding common sleep disorders—their symptoms and impact—can empower you to seek appropriate care. Here’s an overview of the most prevalent sleep disorders.

Insufficient Sleep Syndrome
This condition is marked by consistently getting less sleep than your body needs to function optimally.
Common symptoms include feeling tired all day, irritability or mood swings, and trouble focusing and thinking clearly. Chronic insufficient sleep can increase the risk of heart disease, high blood pressure, obesity, diabetes, immune system dysfunction, depression, anxiety, and impaired cognitive function. It can also significantly reduce quality of life.

Insomnia
Insomnia involves difficulty falling asleep, staying asleep, or waking up too early—often accompanied by feeling unrefreshed during the day. Symptoms include fatigue, mood changes like irritability or anxiety, and problems concentrating or remembering things. Untreated insomnia is linked to a higher risk of depression, anxiety, heart disease, diabetes, cognitive decline, and accidents. It can also lead to reduced life expectancy and diminished overall well-being.

Obstructive Sleep Apnea (OSA)
OSA is a sleep-related breathing disorder where the airway becomes partially or completely blocked during sleep, disrupting breathing and oxygen levels. Common symptoms include loud snoring, gasping or choking during sleep, and feeling very tired during the day despite sleeping all night. Many individuals experience excessive daytime sleepiness and poor concentration. Without treatment, OSA can lead to high blood pressure, heart failure, stroke, diabetes, memory problems, accidents, and reduced quality of life. Untreated OSA is also associated with higher mortality rates.

Restless Legs Syndrome (RLS)
This condition creates an overwhelming urge to move your legs, often paired with uncomfortable feelings like tingling or crawling. The symptoms worsen at rest, especially at bedtime, and movement temporarily relieves the discomfort. Untreated RLS can cause chronic sleep deprivation, leading to excessive daytime sleepiness, cognitive difficulties, mood swings, and a higher risk of cardiovascular diseases like hypertension and heart disease.

Parasomnias
Parasomnias include unusual behaviors during sleep, such as sleepwalking, night terrors, or acting out dreams, which is known as REM Sleep Behavior Disorder (RBD). Symptoms of RBD include shouting, flailing, or physically acting out vivid dreams due to a loss of muscle control during REM sleep. RBD increases the risk of injury to the affected individual or their bed partner. It is also linked to neurodegenerative diseases like Parkinson’s. Other parasomnias may result in injuries or disrupted daytime functioning due to poor-quality sleep.

Circadian Rhythm Sleep-Wake Disorders
These disorders occur when your body’s internal clock is misaligned with external time cues, such as light and social obligations. Examples include delayed sleep-wake phase disorder (falling asleep too late) and shift work disorder (difficulty sleeping due to irregular work hours). Symptoms include difficulty falling asleep, waking at desired times, and feeling tired during the day. Untreated circadian rhythm disorders can lead to chronic sleep deprivation, cognitive impairments, mood disturbances, and higher risks of heart disease and metabolic disorders.

Hypersomnias (e.g., Narcolepsy)
Hypersomnias are characterized by excessive daytime sleepiness that is unrelated to a lack of sleep. Narcolepsy, a type of hypersomnia, may include additional symptoms such as sudden daytime sleep attacks, loss of muscle control triggered by emotions (cataplexy), vivid hallucinations, and sleep paralysis.

Why Sleep Disorders Matter
Sleep disorders, if left untreated, can lead to significant health problems such as cardiovascular disease, diabetes, anxiety, depression, and dementia. Many sleep disorders are underdiagnosed, but effective treatments are available to help you reclaim your health and quality of life. If you experience ongoing sleep challenges talk to a healthcare provider.
