Is it bad to wake up during REM sleep?
Multiple studies have shown that lack of slow wave sleep contributes to daytime grogginess and poor mood. Additionally, waking up during REM cycles interrupts our flow of aggregating memory. In order to make sure you wake up during light sleep, try and schedule your sleep in 90-minute multiples.
“REM sleep is a paradox because even though it's a stage of sleep, your brain is wide awake,” says Dr. Chhatwal. It's no surprise then that if you wake up in the middle of a REM cycle, you're more likely to remember the dream you were just having.
Over more cycles, the NREM stages get lighter, and the REM stages get longer. Ideally, the body will pass through four to five of these cycles each night. Waking up at the end of the cycle, when sleep is lightest, may be best to help the person wake feeling more rested and ready to start the day.
These cycles alternate between deep sleep (REM) and sleep (non-REM). If you wake up during a REM cycle, you are likely to feel groggy the next day. But if you awaken during a non-REM sleep cycle, you are likely to feel attentive and alert the next day.
Although false awakenings have been described as vivid and uncanny, experts do not believe they are harmful. But, like other events that happen on the threshold between wake and sleep, false awakenings may sometimes provoke fear, unease , or anxiety.
A 2011 study showed that people who have more theta brain-wave activity in their prefrontal cortex after waking from REM sleep have better dream recall. Theta activity indicates a slower-paced, more relaxed brain state, and greater theta activity has been linked to enhanced memory while awake.
Despite the fact that alarm clocks are a widespread phenomenon, the jolt that wakes you up isn't good for you. In fact, it increases your blood pressure and heart rate. Two things that can have a detrimental effect on your health in the long term. As the adrenaline kicks in, you start off the day stressed.
When you experience an unusually large amount of REM sleep during one night, it's because your body has recognized that you were sleep deprived and is helping you correct that. So, occasionally having too much REM sleep isn't necessarily a cause for concern.
These awakenings can be exacerbated by outside factors like noise, artificial light, a partner moving, or other causes. Combating such outside stimulus by creating a cool, dark and quiet bedroom can help minimize these interruptions and figure out how to get more deep sleep.
Each cycle consists of four stages: three stages of non-rapid eye movement (non-REM) sleep and one stage of rapid eye movement (REM) sleep. A person will cycle through the stages of non-REM and REM sleep 4–6 times per night, on average.
What stage of sleep should you wake up in?
You need stage 3 NREM sleep to wake up feeling rested. Without enough stage 3 sleep, you feel tired and drained even if you slept for a long time. That's why your body automatically tries to get as much stage 3 sleep into your sleeping period as early as possible.
Hypnic headaches often occur during rapid eye movement (REM) sleep, so it's possible that an area of the brain involved with processing pain gets activated, leading to a hypnic headache. Hypnic headaches may also be linked to melatonin production.
People in pain or discomfort often have difficulty getting deep sleep. Loud noises and bright lights in or near the sleeping environment may also make it difficult to get deep sleep. To get the best possible sleep, sleepers should keep their bedroom dark, quiet, and cool with a comfortable bed and pillows.
False awakening is defined as, “a vivid and convincing dream about awakening from sleep, while the dreamer in reality continues to sleep.” In contrast to normal dreams, which are often nonsensical fantasies, false awakenings are usually completely mundane.
In simple terms, a false awakening is thinking you are awake while you are dreaming. They are very common, and almost every person will have them at some point in their life. With that said, the symptoms can vary from one person to the next.
During non-REM sleep, the thalamus is inactive, but during REM sleep, when we are dreaming, the thalamus is active, sending the cerebral cortex images, sounds, and sensations, which is why we are able to hear, feel, and see in our dreams similarly to how we do when we are awake.
So, is dreaming a sign of good sleep? Researchers believe it either reflects or contributes to healthy sleep. If you rarely or never dream, that may indicate you're sleep-deprived. However, other factors affect dream recall, so you should talk with your doctor.
On average you'll go through 3-5 REM cycles per night, with each episode getting longer as the night progresses. The final one may last roughly an hour. For healthy adults, spending 20-25% of your time asleep in the REM stage is a good goal. If you get 7-8 hours of sleep, around 90 minutes of that should be REM.
Nutrition is key to sleeping well, but even normal functions during the day. And if you're twitching not only at night but also during the day, you could be deficient in Vitamin D, Vitamin B12, or an imbalance of Calcium.
“An adrenaline rush can have detrimental effects on health. In people with heart disease, it can cause a weakening of the heart muscle, heart failure or a heart attack. So steer clear of haunted houses if you have any of these diagnoses.”
What does being startled do to your heart?
Your heart rate and blood pressure can go up, which can impact your heart's electrical system. You can experience symptoms similar to a heart attack, including chest pain, shortness of breath and sweating.
REM sleep is characterized by relaxed muscles, quick eye movement, irregular breathing, elevated heart rate, and increased brain activity. Most adults need about two hours of REM sleep each night. REM sleep plays a role in memory consolidation, emotional processing, brain development, and dreaming.
In summary, while Fitbit and most other sleep trackers do a passable job of estimating how long you were asleep for, they struggle to predict how long you were in specific sleep stages. As a result, they may not provide you with the information you need to improve your sleep and may even increase sleep anxiety.

Most of us wake up three to four times during the night for varied reasons, and this is considered a part of a normal sleep pattern. However, a lot of us wake more frequently, sometimes even every two to three hours in the night. This is a reason for concern.
