Even though you’re tired, when you go to bed, you cannot sleep. You can only sleep late at night. On the other hand, you may be able to sleep normally during the weekend but not when you need to get up early for work.
One can easily assume that this is caused by insomnia. But at times, the cause may not actually be the lack of ability to sleep. Rather, it may be something else that affects your body; for example, the circadian rhythm of your body.
Knowing how circadian rhythm sleep disorders differ from insomnia will allow you to better understand your problem with sleep and possible ways to deal with it.
What Is the Circadian Rhythm?
Your circadian rhythm is your internal clock, which works on a roughly 24-hour schedule and regulates your sleep-wake pattern and other physiological processes. (1)
One of the most powerful cues for this internal biological clock is light. Light in the morning helps cue you to wake up, while darkness helps get you ready for bed.
The brain also secretes melatonin, which is a hormone involved in regulating your sleep and wake cycles. The secretion of melatonin increases in the evening to help prepare the body for sleep.
Misalignment between your biological clock and your everyday schedule can make you feel awake even though you want to go to sleep, or asleep even though you want to stay awake.
That discrepancy can lead to circadian rhythm sleep disorders.
Circadian Rhythm Sleep Problems vs Insomnia
So, what is the distinction between sleep disorder and insomnia?
In general, insomnia is marked by problems with falling asleep, staying asleep or obtaining restful sleep even if there are sufficient chances for one to get some sleep. (2)
Circadian rhythm disorders have their differences though. The thing is that your organism is able to fall asleep naturally, but only not at the required time.
For instance, let’s say that you get tired naturally at around 1 or 2 in the morning and sleep well till 9 or 10 in the morning. If you have to sleep at 10 in the night and wake up at 6 in the morning, you might end up lying awake for hours.
It may not even be about your inability to sleep but perhaps about how your body clock is working on a different cycle.
Signs It’s Not Insomnia
Several indicators that it is not insomnia and that your sleep problems could be due to your circadian rhythm include:
- You fall asleep naturally later than your desired bedtime.
- You sleep well if you get the chance to sleep on your own schedule.
- You struggle to wake up early but can sleep well later in the day.
- Your sleep issues developed after shift work, travel, or a schedule change.
- There is a huge difference between your bedtimes and wake times during weekdays and weekends.
- You remain alert at night even though you are exhausted throughout the day.
- You are constantly exposed to bright screens or artificial lighting late into the night.
However, these symptoms do not necessarily indicate that you suffer from any circadian rhythm disorder. There are many reasons for poor sleep quality such as stress, medicines, physical ailments, etc.
Why Modern Life Can Disrupt Your Body Clock
Our body clock has been programmed on the basis of daily rhythms of light and dark, but modern lifestyles tend to disrupt such cycles. (3)
Screen exposure at night, shift work, sleeping late on weekends, night shifts, traveling between time zones, and irregular eating or activity schedules are some factors that can influence daily habits.
Repeatedly staying up late can gradually alter the natural sleep schedule of some individuals.
This creates a frustrating cycle in which you remain awake because you are not tired, sleep late due to staying awake and then having problems waking up the following morning.
How to Fix Circadian Rhythm Sleep Problems
When your sleep is out of whack, small and consistent shifts may help reset your body’s internal clock. (4)
1. Maintain regular wake-up time
It is better that you concentrate not only on the bedtime but also on the wake-up time. Even during the weekend you should keep this schedule.
2. Get some morning sunlight
Morning sunlight is a crucial environmental signal for your circadian rhythm. Getting out into the sun after you wake up helps establish the contrast between day and night.
3. Dim bright lights at night time
While getting closer to bedtime, it is recommended to dim down the lights in your surrounding area and avoid exposure to bright screens if you get easily distracted.
4. Establish a pre-sleep ritual
Give your mind a systematic shift from the daily activities to sleeping. You may engage yourself in reading, stretching, meditation, or any other relaxing activity before going to bed.
5. Consistency is key
Circadian rhythms thrive on patterns. When you keep changing the time you go to bed and when you wake up, you might have problems creating a routine sleep cycle.
6. Check caffeine and other stimulants
Caffeine stays in the body for many hours. If you find it hard to sleep, try avoiding caffeine in the evening. (5)
Where Can Sleep Supplements Fit In?
A good sleeping pattern needs to be the basis for quality sleep. Nevertheless, there are also some individuals who try using nutritional supplements in their sleeping pattern.
At Health Etc., the doctor-formulated wellness products are designed around everyday health needs. The Go2 Sleep Gummy combines ingredients such as melatonin, passionflower extract, saffron, ashwagandha, Valeriana wallichii and chamomile in a convenient gummy format.
However, these products should always be viewed as complementary to good sleeping practices and not a replacement for solving the sleeping issue itself.
However, if you suffer from sleeping problems on a consistent basis, it is recommended that you consult a medical practitioner prior to taking sleep supplements.
When Is It Time to Talk to a Doctor?
Having poor sleep at times is normal. But continuous sleep problems cannot just be ignored.
Consult a healthcare professional if:
- You have problems sleeping at night.
- You are always sleepy during daytime.
- You feel unrefreshed after waking up.
- Your sleeping pattern is affecting your obligations.
- You are always waking up at night.
- You experience noisy snoring, breathing problems during sleep.
- Trying to change your sleeping pattern hasn’t helped you.
A healthcare professional may be able to help identify if your symptoms relate to insomnia, a circadian rhythm disorder, another sleep disorder, or an existing medical condition.
Conclusion
All sleep problems are not insomnia.
In certain situations, your body may just require sleep at a different time than what your schedule requires. Learning about circadian rhythm sleep disorders can assist in clarifying why you might feel completely alert at bedtime but have trouble waking up in the morning.
First, reinforce the signals sent from your body: go to bed and wake up regularly, get sunlight in the morning, limit nighttime exposure to light, and adopt a relaxing pre-sleep ritual.
But if your sleep issues persist despite all these alterations, do not make assumptions about what is causing it. Consulting a professional can assist you to determine if you have insomnia, circadian rhythm disorder, or any other sleep disorder.
FAQ
- Is circadian rhythm disorder the same as insomnia?
No. The problem of insomnia lies in difficulty sleeping in spite of adequate opportunities for sleeping. On the other hand, issues relating to circadian rhythms concern the misalignment of one’s internal clock and required schedule.
- What are the common signs of circadian rhythm sleep problems?
Signs which are common include trouble falling asleep at the right time, trouble waking up at the appropriate time, excessive sleepiness during the day and normal sleep when on a preferred schedule.
- How can I reset my circadian rhythm naturally?
Waking up at the same time every day, exposure to sunlight in the mornings, minimal light exposure in the evenings, having a consistent bedtime routine, and other regular daily activities may aid healthy circadian rhythms.
- Can melatonin help with circadian rhythm problems?
Melatonin helps with sleep regulation, but its use will depend on the person and the reason for their sleep issues. Consult a healthcare practitioner before taking melatonin or any other sleep supplement.
- When should I seek help for sleep problems?
In case sleep problems continue, interfere with daytime activities, or are accompanied by symptoms like loud snoring and breathing problems, one should seek help from a medical expert.
