Sleep disorders are comprised of the several conditions which result in affecting the habit of sleeping. To have a good and proper sleep is important as it has a direct effect on mood, hormone levels, and weight. There are an approximate 96 diagnosable sleep disorders, few of them are mentioned below:


It is considered the most common sleep disorder. According to research, only 10% of reports are filed against the issue of chronic insomnia. Insomnia is a major factor for having a sleep of poor quality due to the following reasons:

· Difficulty in sleeping

· Waking in the middle of the night and finds to difficult to sleep again

· As per plan or desire waking up early in the morning

If a person is suffering from sleep issues then there are several difficulties and troubles which he/she may experience for a whole day. Insomnia reported symptoms are mentioned below:

· A person may feel like sleep was un-refreshing

· A person may experience sleepiness during excessive daytime

· Lack of energy

Insomnia depends on the time period that how often insomnia occurs and the effect of insomnia lasts for how much time. There are two major types of insomnia; acute and chronic. In acute insomnia, a person experiences the sleep loss for only a short period of time (a period of few weeks only). Whereas in chronic insomnia, a person has to experience poor quality sleep and this effect lasts for a time period of one month or more. Insomnia can be raised for a number of different reasons which can be defined in terms of environmental influence, stress, worry, and psychiatric problems. Even in some cases, insomnia may occur without any reason.

Sleep apnea:

It is another most common type of sleep disorder. According to research, around 80% of the people do not even realize that they are suffering from the issue of sleep apnea. A person is said to have sleep apnea when a person stops breathing for several seconds specifically in the middle of the night which results in blocking the upper respiratory system. As the person sleeps, the soft tissues which are present in the throat collapse and relax which results in blocking of oxygen. This partial blocking results in either full blockage or snoring. When the breathing does not get a proper response, the brain system gets disrupted which results in sleep disturbance.

Other sleep disorders are:

· Restless Leg Syndrome

· Narcolepsy

· Sleep-related breathing disorders

· Central disorders of hypersomnolence

· Circadian rhythm sleep-wake disorders

· Parasomnias

· Sleep-related movement disorders
