Have you ever stayed awake at midnight and not being able to go back to sleep again? Or getting sleep but not feeling refreshed by it? You might experience circadian rhythm disorder. You should have questions about what circadian rhythm disorder is and how to fix it. Don’t worry, the following article will reveal the answer for you.

What is circadian rhythm disorder?
Simply to say, your internal clock rotates between sleep and wakefulness throughout the day. This 24-hour sleep-wake cycle is known as our circadian rhythm, which plays a vital role in our sleep cycle.
In addition to sleep, this rhythm helps regulate body temperature, eating and digestion, and hormonal activity. A healthy person usually wakes up in the morning and becomes tired throughout the day, while a person with circadian rhythm disorder would have excessive daytime sleepiness.
Here are some common reasons that would cause the disorder of circadian rhythm:
- Jet lag
You might experience jet lag after the flight which passes over multiple time zones, then feel daytime fatigue and temporary sleep disturbances. It would cause a person too much sleepiness or daytime alertness in the following days. However, it is usually not a serious problem if the person practices healthy sleep hygiene during the post-flight period.

- Shift work
People whose jobs require them to work partly or completely at night often experience shiftwork disorder, and they always lose one and four hours of sleep every 24 hours. This disorder can be dangerous because it increases the risk of accidents either at people’s workplace or on the road during a late-night or early-morning commute.
- Mental health disorder
People who have mental disease might experience irregular sleep-wake disorders. The fragmented sleep cycle of this disorder would yield periods of sleep that last for several hours. As a result, people with this disorder would frequently nap throughout the day.

How to fix circadian rhythm disorder?
So how to fix circadian rhythm disorder if it affects our sleep hygiene so much? Here are 5 tips for you to go back to a good night’s sleep.
1.Get a good sleeping environment
A comfortable and quiet sleeping environment is vital for a good night’s rest. Loud, distracting noises would make it difficult to fall asleep or stay asleep. Therefore, you can create white noise to mask the environmental noise, such as the drowning fan or the air conditioner.

2. Practice relaxation
Try to focus on more calming activities to help you sleep better. When you’re stressed or anxious, your body produces more cortisol, and the higher the cortisol, the more awake you feel.
So, creating a relaxing bedtime ritual by practicing relaxation, such as yoga, stretching and meditation may help you reduce stress and its negative effects on sleep.

3. Avoid snaps during the day
If you have an irregular sleep schedule, avoid long snaps during the day, or you will make it difficult to go back to sleep at night again.
Long naps would cause grogginess, and if you must snap, try not to make it more than 30 minutes. It’d also better to nap before 3 p.m. so that your nighttime sleep would not be disrupted.
4. Get daily exercise
One of the best ways to reset your internal clock is to get daily exercise, which would help you sleep better by promoting melatonin production.
Technically, most of your tissues including our skeletal muscle are linked to your biological clock. So during the exercise, your muscle would respond to align your circadian rhythm.

5. Eat early
As we know, your sleep hygiene is closely linked to your eating habits. An early dinner can give your body enough time to digest the meal and help you to get used to a routine.

In conclusion, these 5 tips can help you fix the circadian rhythm disorder:
- Get a good sleeping environment
