Sleep state misperception is a condition where you underestimate how much you've slept the night before. You may feel like you were awake all night, but you actually slept for hours. It's also called paradoxical insomnia or subjective insomnia.
There are several causes of unrestful sleep, such as obstructive sleep apnea, medications, especially overuse of sleep aids, stress, depression, anxiety, and alcohol.
Hypnagogic sleep paralysis occurs when your body has trouble transitioning into the REM cycle (falling asleep) and hypnopompic occurs when your body has trouble transitioning out of it (waking up). Studies estimate that most people experience sleep paralysis at least once, although they may not even be aware of it.
Apparently, the experience of sleeping without even knowing it is not uncommon among those with the condition. Scientists have identified the phenomenon and, although they did not fully understand it, labeled it “sleep misperception.”
Simply put, microsleep is when you fall asleep for a period of several seconds. As the name implies, microsleep occurs so quickly that people who have an episode might not even realize they have fallen asleep. Microsleep can occur at any time of day, not just at night.
We wake up feeling intense because of the stored up Cortisol levels throughout the night, which makes us feel anxious, so our bodies continue to pump out Cortisol, which creates more anxiety, which produces more cortisol, which causes us to feel more anxious, etc.
After awakening from a nap or a long sleep episode (for example, 7 to 8 hours of sleep at night), people tend to feel groggy from sleep inertia. Sleep inertia is a temporary disorientation and decline in performance and/or mood after awakening from sleep.
Parasomnias are a sub-category of sleep disorder. They involve abnormal and unnatural movements, behaviours, emotions, perceptions and dreams that occur while falling asleep, during sleep, between sleep stages or upon waking. Most people experience a parasomnia during their lifetime.
Fatigue is common in depression, and one of the causes of that fatigue is sleep inertia. Sleep inertia is a transitional state between sleep and wakefulness. Sometimes called sleep drunkenness, it is characterized by grogginess, poor mental performance, physical slowing, and dyscoordination.
If you or a loved one feel sleepy or fatigued, despite having 7-8 hours of sleep, it could indicate poor sleep quality or be a sign of an underlying sleep disorder. If you have questions or concerns about your sleep health, please speak with your primary care provider.
Morning anxiety can feel like generalized anxiety, with physical and cognitive symptoms, says Rex. These may include racing thoughts, inability to concentrate, muscle tension, or a rapid heart rate, which are also associated with generalized anxiety disorder, or GAD.
Researchers have found that cortisol is highest in the first hour of waking for people with an increased level of anxiety. This helps explain why you may experience an increase in anxiety in the morning.
You may feel sleepy after a full night's sleep due to a medical condition. Medical conditions that can make you tired, or make it hard to meet your sleep need, include: Sleep disorders like obstructive sleep apnea, narcolepsy, and restless leg syndrome. Iron deficiency anemia.
Should you go back to bed if tired? Waking up tired doesn't necessarily mean you should go back to bed and sleep more, especially if you're getting the recommended 7-9 hours of sleep each night. Experiencing a little tiredness upon waking is totally normal and should subside within 15 minutes to an hour.
If you have built up sleep debt, allow extra time for sleep: go to bed early. You sleep more deeply when you are sleep deprived, so you do not need to “pay back” hour for hour the lost sleep. However, if you have not had enough sleep for many days, it might take several nights of good-quality sleep to recover.
You're most likely waking up tired every day because of sleep inertia, the natural grogginess you get when you transition from being asleep to awake. Sleep debt, being out of sync with your circadian rhythm, a sleep disorder, or an underlying medical condition could also be to blame.
There are also a number of common health conditions that can lead to ongoing tiredness. Just a few include diabetes, anemia, depression, anxiety disorder, food sensitivities, hypothyroidism, hepatitis C, obstructive sleep apnea, heart disease, and nasal congestion.
And while the occasional long sleep is generally nothing to worry about, oversleeping several days a week could be a sign that something more serious is going on.
The cumulative effects of sleep loss and sleep disorders have been associated with a wide range of deleterious health consequences including an increased risk of hypertension, diabetes, obesity, depression, heart attack, and stroke.
While most adults need at least seven hours of sleep, some adults average five or fewer hours of sleep each night. While it may seem like enough sleep, regularly getting only five hours of sleep each night may lead to sleep deprivation.
