I Sleep 6 Hours Get Up Then Nap Again 2 Hours Later

Julia was at wit's end. She has been suffering from indisposition for the past 10 years, since she entered menopause. She keeps waking upwardly after 5 hours, despite trying every over-the-counter and prescription medication available. She has no trouble falling asleep, but is not able to stay asleep for more than v hours, typically waking up at 3AM after falling asleep at 10PM. Oftentimes, she has to go to the bathroom when she awakens, merely it'south not also much urine. She even saw a behavioral sleep specialist who offered cerebral behavioral therapy for indisposition (CBT-i), which only helped temporarily.

Julia's history is typical for what's chosen sleep maintenance insomnia, where you tin can't stay asleep or go on waking up after you're able to fall asleep. This differs from sleep onset insomnia, where yous're not able to fall asleep within 20 to 30 minutes of getting into bed. The accustomed explanation for insomnia is that it's a complex interaction betwixt poor sleep routines, behavior and thoughts, in add-on to a baseline hyperarousal of your encephalon. Substantially, you can't close down your brain when you desire to get to sleep.

One of the potential consequences of sleep maintenance insomnia is that with continuous awakenings at AM and not being able to go back to slumber is that your slumber clock becomes avant-garde, or gets pushed backwards. This could potentially lead to avant-garde sleep phase syndrome, a condition that's commonly seen in the elderly. In this status, you'll want to go to sleep much earlier in the evening, such as 8PM, rather than at 10PM.

I've e'er wondered why people tend to wake up effectually 3AM,  whether it's insomnia, dark urination, or asthma. The nearly obvious connection betwixt these iii connections is that you spend longer periods of REM sleep (your dream phase), starting around 3AM. Phase REM is also when your muscles are most relaxed, which can predispose you to have breathing problems. I've been doing thought experiments about his concept, and I'thou convinced that we need to recall about sleep maintenance indisposition in a completely different fashion—maybe it's a result of a breathing trouble.

Before I go over my arguments, a few basic sleep concepts need to be reviewed.

Sleep Position

If you come across photos or drawing of people sleeping, yous'll ofttimes see sleep being depicted equally someone sleeping on the back. Withal, virtually modern Western people adopt to slumber on their sides or stomach. I of many reasons is that supine (back) sleep will allow the soft tissues of the natural language and soft palate and fall back more than due to gravity when supine.

Menopause

Equally women go through menopause, throat muscles will relax somewhat due to lowered progesterone levels. This study found that genioglossus muscle (tongue) activity is lower in post-menopausal women compared to pre-menopausal women. This is why women on hormone replacement therapy tend to sleep slightly amend.

Your Circadian Rhythm

Some other major slumber concept that'south important to understand are 2 processes that are involved in sleep regulation. The first one is the well-known cyclic rhythm. For many of us here on Earth, we are on a 24 hour bicycle. The cyclic rhythm, which is regulated by lite, cycles up and down between two 12-hour intervals. This is called the C process. This is what makes you lot alert during the mean solar day and drowsy at nighttime.

Your Drive for Slumber

There's another simultaneous sleep-related phenomena called the S process. This is your bulldoze for slumber, which is minimal in the morning time when you first wake up, but and so increases gradually reaching its peak before yous fall asleep. Once yous're comatose, it drops dorsum down to the baseline depression level at which betoken you'll wake up.

Procedure Due south also corresponds to your level of adenosine that builds upward in your brain. Adenosine inhibits wakefulness. As the day progresses, adenosine levels slowly increase. Ingesting caffeine from drinking java is one way that we cake the effects of adenosine.

The Importance of Slumber Stage

Now at that place'south one more piece to the puzzle that's critical. This is your sleep cycle. Normally, yous'll cycle between iv defined stages of slumber: Wake, N1, N2, N3, REM. N1 and N2 are the lighter stages of slumber and N3 is deep slumber. During N1 through N3, your muscles get gradually more relaxed, merely in REM sleep (rapid center move and dream stage),  your muscles are completely relaxed.

You'll achieve deep sleep (N3) in the early part of the nighttime, only as y'all progress through 4 to 5 sleep cycles (90 to 120 minutes long), N3 gets shorter and shorter and REM becomes longer and longer. Effectually 3 to 4 AM is when you begin to take longer periods of REM slumber.

There are many unlike explanations on what causes us to wake upwards prematurely in the morning, but it'south probably a combination of  these three processes, forth with sunlight that arrives in the morning time. When you're about to wake up, your cyclic (wake forces) are beginning to increase from its everyman signal, your slumber drive (Southward) is at its lowest point, and you're most likely in REM sleep, when muscles are nearly relaxed, leading to possible obstructed animate. This  can be a natural, normal waking machinery. Notice that in many cases you're waking up during a dream in the morning. Adding sunlight is another cue for y'all to wake upwardly.

In addition, the lowest bespeak in the cyclic bicycle is called the singularity. It typically occurs effectually 2 hours before your natural wake upward time. It's besides the fourth dimension when your core body temperature is at its lowest. On the C&S effigy, notice that this dip is virtually 2 hours before wake time. Nosotros also know that equally cadre body temperature rises, you're more probable to wake up.

In the effigy below, I've juxtaposed the hypnogram (slumber stages) underneath the C&South figure during viii hours of sleep.

All of the above is assuming that you have normal upper airway anatomy and you are able to wake up after sleeping 7 to 8 hours without any issues. However, if you take upper airway narrowing due to large tonsils or small jaws with dental crowding, yous're more likely to partially or totally stop animate, whether it's for 3 seconds or 25 seconds. Totally obstructed breathing for more than than 10 seconds is chosen an apnea if detected during a sleep study. A breathing pause for less than x seconds won't be counted equally a formal respiratory event (apneas, hypopnea or RERA) but will most likely be counted every bit an arousal.

Nosotros also know that obstructed breathing is more probable to occur during REM sleep, specially when yous're on your back. If you accept more narrow upper airways, then the higher the likelihood of more frequent animate pauses around 3-4 AM, when you're in longer periods of REM slumber. If you add together the various other factors mentioned above (circadian factors, slumber bulldoze, sleep position, sleep stage, low-cal, etc.), then you lot're more likely to wake upwardly around this time.

Brain hyperarousal

One of the hallmarks of insomniacs is the disability shut downwards the brain when going to sleep, or after a nighttime arousal. It think you'll agree with me that waking up due to choking and breathing pauses tin can be a major crusade of physiologic, emotional and psychological stress.

Nighttime urination

Some of you may take to go to the bathroom to urinate. This is a common condition (nocturia) in people with obstructive sleep apnea or upper airway resistance syndrome due to a hormone (atrial natriuretic peptide) that's created by your heart in response to stimulation from obstructed breathing, leading to more urine product. Some of you are able to become dorsum to slumber, but some of you lot can't autumn back comatose. Whether or not you can autumn back comatose may depend on how violently y'all woke upward. If y'all merely had a xxx 2d choking episode, this will lead to a major stress response, with center charge per unit blood pressure elevations. It'due south unlikely you'll exist able to fall back asleep.

Putting the pieces together

In medicine, and especially slumber medicine, nosotros like to categorize medical weather into divide categories. It assumes that obstructive slumber apnea is completely different from insomnia. However, when it comes to these two conditions, in that location is compelling evidence that there can be a swell deal of overlap when it comes to presenting symptoms.

One example of this overlapping phenomenon is a study performed past Dr. Barry Cracow. He and his colleague reviewed 218 patients with prescription medication resistant insomnia, and 75% were institute to have obstructive sleep apnea based on formal sleep studies.

Julia eventually fabricated her way to find me and not surprisingly, she was institute to have moderately obstructive sleep apnea (AHI 20).  She began using CPAP, and finally able to slumber for 7 hours again like she used to when she was in her teens. Looking back on her history, she suffered a shoulder near 8 years ago. This forced her to sleep on her back, when she commonly preferred to sleep on her side. She began to gain weight after, and began to snore heavily.

This alternative explanation for slumber maintenance insomnia may seem a chip fatty fetched for traditional sleep scientists, only looking at this from a sleep-animate standpoint, it makes a lot of sense. How many of you lot keep waking up much earlier than your preferred time? What accept to tried and then far? Delight enter your responses in the text box below.
