Advanced sleep phase disorder is the opposite of delayed sleep phase disorder. You actually fall asleep a few hours before most people and then awaken very early in the morning. Disorders related to your circadian rhythm may result in having difficulty falling asleep at night, waking frequently throughout the night, and waking and not being able to go back to sleep in the middle of the night.
Maintaining your circadian rhythm is vital to your health. If you experience a disruption to your circadian rhythm and struggle to get the proper amount of sleep, you may experience both short-term and long-term consequences to your health. Disruption to your circadian rhythm can cause health conditions in several parts of the body in the long term. This includes your:.
You may be more susceptible to diabetes , obesity, and mental health conditions as well. Short-term disruptions to your circadian rhythm may result in problems with memory or lack of energy.
There are several reasons you may want to talk to a doctor about an issue with your circadian rhythm. Living a healthy, active lifestyle that promotes proper rest will help you maintain this important component of your body. Reach out to your doctor if you experience prolonged difficulties sleeping or extreme fatigue during the day to find out how you can realign with your circadian rhythm and get proper rest.

Studies in fruit flies suggest that these proteins help activate feelings of wakefulness, alertness, and sleepiness. However, signals from the environment also affect circadian rhythms. For instance, exposure to light at a different time of day can reset when the body turns on Period and Cryptochrome genes. However, most people notice the effect of circadian rhythms on their sleep patterns. The SCN controls the production of melatonin, a hormone that makes you sleepy.
It receives information about incoming light from the optic nerves, which relay information from the eyes to the brain. When there is less light—for example, at night—the SCN tells the brain to make more melatonin so you get drowsy. In , researchers Jeffrey C. Hall, Michael Rosbash, and Michael W. Young won the prestigious Nobel Prize for their circadian rhythms research.
The scientists showed that the gene produces a protein that builds up in cells overnight, then breaks down during the day. This process can affect when you sleep, how sharply your brain functions, and more. Circadian rhythm neurons in the fruit fly brain. Changes in our body and environmental factors can cause our circadian rhythms and the natural light-dark cycle to be out of sync.
For example:. These changes can cause sleep disorders, and may lead to other chronic health conditions, such as obesity, diabetes, depression, bipolar disorder, and seasonal affective disorder. When you pass through different time zones, your biological clock will be different from the local time.
When you wake up at a. Your biological clock will reset, but it will do so at a different rate.
