Disorders of the Circadian Rhythm: What Are They?

Circadian rhythms are similar to the natural clock that your body functions with. They regulate your sleep-wake cycle and occur around once every twenty-four hours. A region of your brain known as the suprachiasmatic nucleus (SCN) is responsible for regulating these rhythms. This region reacts to the amounts of light and darkness that are present in your environment. These rhythms are extremely important for your body since they determine everything from when you feel drowsy or awake to when you eat and how your body processes food.

Your Circadian Clock and Why It Is Important

When it comes to maintaining normal sleep patterns, your circadian clock is absolutely necessary. In addition to exerting an influence on your hormones, digestion, and body temperature, it makes you feel more alert throughout the day and more tired at night. The inability to keep track of this clock can result in sleep difficulties, which in turn can cause you to feel exhausted and have an impact on your general health.

When things don’t go as planned, what happens?

Circadian rhythm disorders are conditions that occur when the internal clock of an individual does not correspond with the external environment. It may be difficult to operate regularly as a result of these disorders because they can really disrupt your sleep and your day-to-day life.

Individuals who suffer from DSPD frequently have trouble falling asleep until very late at night or very early in the morning, and they also have a difficult time waking up in order to carry out their daily duties. It is not uncommon for adolescents and young people to experience this, which can make it challenging to adhere to regular schedules.

(ASPD) stands for advanced sleep phase disorder.


You experience feelings of sleepiness in the early evening when you have ASPD, and you wake up very early in the morning. This can make it difficult to stay awake later in the day and can also interfere with activities that take place in the evening. It is more prevalent in people who are older.
