In general, the longer a person naps, the more likely they are to feel woozy, foggy, groggy, or even nauseous when they get up. This is because longer naps increase the chances of sleep inertia or acid reflux.
Your stomach produces excess acid when stressed or tired and this in turn irritates its lining and triggers nausea. It then settles with food by dissipating your stomach acids. A dehydrated body can trigger nausea. Overnight it's easy to dehydrate (and exacerbated if you've had some alcohol).
Research shows that washing your face and getting some sunlight can combat post-nap grogginess, as can listening to music. Light exercise, such as stretching and walking, as well as intense workouts can boost energy and mood, which can fend off afternoon slumps.
What Is Sleep Inertia? Sleep inertia is the feeling of grogginess, disorientation, drowsiness, and cognitive impairment that immediately follows waking. View Source . Sleep inertia generally lasts for 15 to 60 minutes.
According to Dr. Chelsie Rohrscheib, head sleep expert and sleep scientist at Wesper, “Sleep inertia is a state of extreme grogginess and cognitive dysfunction immediately after waking that is often accompanied by symptoms such as excessive drowsiness, confusion, brain fog, nausea, and headache.”
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.
Sleep inertia, the period of grogginess and impaired performance experienced after waking, is a potential side effect of napping. Many industry publications recommend naps of 30 min or less to avoid this side effect.
In general, the best nap length for adults is about 20 minutes and no longer than 30 minutes. Sleeping for 20 minutes allows the napper to get a bit of light sleep to boost alertness without entering into deep sleep. Waking up from deep sleep can cause grogginess and actually worsen sleepiness.
It's extremely common to experience sleep inertia. Although some people wake up bright and refreshed in the morning, almost all of us have had times where we wake up feeling sluggish and a bit confused. For many of us, this feeling happens most mornings, even if it passes within a short time frame.
Your sweat consists of both fluid and electrolytes that are pushed to the skin's surface. There, it's absorbed into the air, causing a cooling effect. At the same time, you aren't replacing this fluid and electrolytes since you're sleeping, leading to dehydration that can cause you to wake up thirsty.
Common problems that may cause nausea and vomiting include: Food allergies. Infections of the stomach or bowels, such as the "stomach flu" or food poisoning. Leaking of stomach contents (food or liquid) upward (also called gastroesophageal reflux or GERD)
Much of this research has focussed on establishing the best length and timing of sleep to minimise sleep inertia. Studies suggest that avoiding sleep periods ending during the circadian low5, 15), and keeping naps to less than 30 min4, 16, 17, 18) to avoid waking from deep sleep15) can minimise sleep inertia magnitude.
“If you're sleep deprived, it takes a lot longer to feel refreshed and alert when you wake up,” says Cynthia Fellman-Couture, RN, a sleep research coordinator at Henry Ford Health. “During sleep there's less blood flow to the brain.
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.
An occasional escape: Naps as a coping mechanism aren't unhealthy if they are not done excessively. Sleep helps us to manage our stress and emotions. Improved physical health: Naps can also be helpful when dealing with medical issues and can give your body the rest it needs to function the rest of the day.
This is because your child is more tired by the end of the day and the timing of this nap can be tricky. Often parents need to shorten the awake time before this last nap and put baby down a little earlier for this nap, giving him/her more time to fall asleep.
A confusional arousal is when a sleeping person appears to wake up but their behavior is unusual or strange. The individual may be disoriented, unresponsive, have slow speech or confused thinking.
Medical treatment options for sexsomnia include: anti-anxiety and antidepressant medications, such as duloxetine and clonazepam. nasal continuous positive airway pressure (CPAP) therapy. antacids and proton-pump inhibitors (PPIs).
Catathrenia is a sleep behavior that's usually harmless but can wake up other people. It happens when someone is sleeping and moans and groans as they breathe out. It's different than snoring, which happens when someone inhales, or breathes in. A sleep specialist can help if you think you have catathrenia.
The exact cause of nighttime groaning is unclear. Some experts hypothesize that the disorder is related to the neurons in the respiratory center of your brain. If these neurons are dysfunctional, they can trigger prolonged exhaling. View Source .
Why do I always feel sick (nausea)? A lack of sleep, poor diet, anxiety, or stress can often cause a person to feel sick. These factors can make a person more susceptible to infection and illness. However, always feeling sick can also signify pregnancy or chronic illness.
