Sleep disorders basically refer to the condition wherein a person faces difficulty in sleeping at night and feels dizziness and sleepy throughout the day. A total of eighty different sleep disorders may affect a human body and in severe cases, these disorders may also interfere with the emotional, mental and physical functioning in a human body.
Types of Common Sleep Disorders
Disturbance in sleep may be due to several reasons. There are many types of common sleep disorders and some of the most common ones are discussed below:
Restless Leg Syndrome
Have you ever realized that the moment you try to sleep, your legs start paining or there is some kind of uncomfortable feeling in your legs that is not letting you sleep? If it is so, you are suffering from a sleep disorder known as restless legs syndrome (RLS).
In this disorder, the person feels a stinging or creeping sensation in legs whenever they are at rest. In case of RLS, you do not feel like keeping your legs at rest because as soon as you rest your legs, the tickly sensation doesn’t let you sleep or take rest.
Many people face a sleep disorder called Insomnia. In case of Insomnia, the person often faces mood swings, lack of concentration, dizziness etc. Insomnia is basically a condition where a person is unable to sleep during nights. Once he/she wakes up in the middle of his sleep, he remains unable to initiate his sleep again and wakes up early in the morning without completing his/her sleep.
This leads to laziness for the rest of the day. Insomnia varies from person to person and is mainly divided into two categories which are called Chronic Insomnia (long term) and Acute Insomnia (short term).
Grinding of Teeth
The grinding of teeth is called as Bruxism in medical terms. Bruxism is mainly marked when a person clutches his jaws and grinds his teeth. Bruxism is not dangerous, but it may cause problems if it is nocturnal. Bruxism is commonly counted as a habit which may be done in conscious or sub conscious mind.
Narcolepsy is a condition where the person faces sleep attacks at odd times in the day. This may happen while doing any work like watching television, studying, working, sitting etc.
In some cases, narcolepsy attacks are controllable, but in some cases they lead to uncontrollable sleep attacks. This condition is also referred as Excessive daytime sleep (EDS).
Hypopnea is also called sleep apnea. This sleep disorder is related to the respiratory system of a person.
While sleeping, when a person faces difficulty in breathing and his sleep is interrupted, then the person is likely suffering from Hypopnea or sleep apnea. Hypopnea can be of two types, Obstructive Hypopnea and central Hypopnea.
Other Common Sleep Disorders
Apart from the above mentioned sleep disorders; there are many other sleep disorders which may affect the sleep of a person. These include cataplexy, night terror, parasomnias, periodic limb movement disorder etc. These disorders are not dangerous, but in severe cases, they may prove to be risky if not treated immediately.
