A sleep disorder is a condition that frequently impacts your ability to get enough quality sleep. While it’s normal to occasionally experience difficulties sleeping, it’s not normal to regularly have problems getting to sleep at night, to wake up feeling exhausted, or to feel sleepy during the day.

Some of the signs and symptoms of sleep disorders include excessive daytime sleepiness, irregular breathing or increased movement during sleep. Other signs and symptoms include an irregular sleep and wake cycle and difficulty falling asleep.

There are many different types of sleep disorders. They're often grouped into categories that explain why they happen or how they affect you. Sleep disorders can also be grouped according to behaviors, problems with your natural sleep-wake cycles, breathing problems, difficulty sleeping or how sleepy you feel during the day.

Frequently having trouble sleeping can be a frustrating and debilitating experience. You sleep badly at night, which leaves you feeling dead-tired in the morning and whatever energy you have quickly drains throughout the day. But then, no matter how exhausted you feel at night, you still have trouble sleeping. And so the cycle begins again, taking a serious toll on your mood, energy, efficiency, and ability to handle stress. Ignoring sleep problems and disorders can damage your physical health and lead to weight gain, car accidents, impaired job performance, memory problems, and strained relationships. If you want to feel your best, stay healthy, and perform up to your potential, quality sleep is a necessity, not a luxury.

• Heart disease
• Heart attack
• Heart failure
• Irregular heartbeat

It also affect various body parts including:

Central nervous system

Your central nervous system is the information highway of your body. Sleep is necessary to keep it functioning properly, but chronic insomnia can disrupt how your body usually sends information. If sleep deprivation continues long enough, you could start having hallucinations — seeing or hearing things that aren’t there. A lack of sleep can also trigger mania in people who have bipolar disorder. Other psychological risks include:

• Impulsive behavior
• Anxiety
• Depression
• Paranoia
• Suicidal thoughts

Immune system

While you sleep, your immune system produces protective, infection-fighting substances like cytokines. It uses these substances to combat foreign invaders such as bacteria and viruses. Cytokines also help you sleep, giving your immune system more energy to defend your body against illness. Sleep deprivation prevents your immune system from building up its forces.

Respiratory system

The relationship between sleep and the respiratory system goes both ways. A nighttime breathing disorder called obstructive sleep apnea (OSA) can interrupt your sleep and lower the quality.

Digestive system

Along with eating too much and not exercising, sleep deprivation is another risk factor for becoming overweight and obese. Sleep affects the levels of two hormones, leptin and ghrelin, which control feelings of hunger and fullness.

Cardiovascular system

Sleep affects processes that keep your heart and blood vessels healthy, including your blood sugar, blood pressure, and inflammation levels. It also plays a vital role in your body’s ability to heal and repair the blood vessels and heart.

Endocrine system

Hormone production is dependent on your sleep. For testosterone production, you need at least three hours of uninterrupted sleep, which is about the time of your first REM episode. Waking up throughout the night could affect hormone production. Show image

Obstructive sleep apnea (OSA) is characterized by partial or complete recurrent upper airway obstruction during sleep. OSA brings many adverse consequences, such as hypertension, obesity, diabetes mellitus, cardiac and encephalic alterations, behavioral, among others, resulting in a significant source of public health care by generating a high financial and social impact. The importance of this assessment proves to be useful, because the incidence of patients with comorbidities associated with AOS has been increasing consistently and presents significant influence in natural disease history.
