What Is Deep Sleep

How To Stop Night Terrors From Happening

Deep sleep is when your body surpasses the first 3 stages and begins to deeply fall into a state of rest and recover. This stage is also known as slow wave sleep. Your body relaxes even more as your temperature decreases and eye movements slow. Your brain waves also decrease but are not without short bursts of elevated activity. In deep sleep you do not wake easily even through loud noises. Your respiratory rate slows, and heartbeat lowers.

Because your body is operating so slowly the body is able to do much needed repairs. Deep sleep is the most important stage out of all the sleep stages because of this main reason. Without deep sleep and repair the body would operate in a more stressed out state. If you have ever had to go without sleep for many days, you know the toll it takes on your overall mood.

When You Should Seek Help

Most children eventually grow out of night terrors. But talk to your GP if they’re occurring several times a night or most nights.

Your GP will be able to check whether something that’s easily treatable is causing the episodes.

For example, large tonsils could be causing breathing problems at night and waking your child.

In a small number of children who have frequent episodes of night terrors, referral to a specialist service may be needed.

What Do Night Terrors Look Like

The reason that night terrors are given such a scary name is that a child experiencing a night terror looks as if shes truly afraid of something.

During a night terror, a child might moan, call out, or even scream. She might sit up or thrash about in her bed. In keeping with the thought that it looks like theyre afraid, kids might sweat, with their hearts beating quickly and eyes open wide with a look of fear on the face.

Again, it can sometimes be unsettling to watch as a parent because it seems like your child is truly suffering.

The more distressing part of a night terror is that no matter what you do, it will often seem like your child isnt responding to you. Or, he might respond, but not really, not in the way he might if he were awake. This was what happened with my sonbefore we realized these were night terrors and wed try to reassure him, he would just shout No! to everything we said and continue to cry.

This inability to respond to you seems odd, but remember: during a night terror, your child isnt really awakehes just having a disrupted transition between the normal stages of sleep.

The hallmark of a night terror is that after a few minutes, your child will fall back asleep on her own without any intervention from you. And, perhaps best for her, she wont remember the experience when she wakes up in the morning.

Does Baby Need To See A Doctor

Night terrors may be scary, but they shouldnt be cause for panic. You may want to talk to your babys doctor if you suspect they are experiencing something other than night terrors, like seizures, or if your baby seems fearful or unsettled throughout the night or even during the day.

You may also want to contact the doctor if your baby has other problematic sleep habits or snores during sleep. These may be signs of other conditions that need to be evaluated.

If you have difficulty establishing regular sleep habits at home, working with a sleep consultant may be useful. Overtiredness and poor sleeping conditions may contribute to the night terrors, and finding someone to help you implement a change in sleep practices at home may reduce the occurrence of night terrors.

If you do talk to your babys doctor, make sure to write down symptoms, sleep schedules, and other routines or unusual behaviors to share with them.

    What You Should Do

    The best thing to do if your child is having an episode of night terrors is to stay calm and wait until they calm down.

    Don’t intervene or interact with them, unless they’re not safe. Night terrors can be frightening to witness, but they don’t harm your child.

    You shouldn’t attempt to wake your child when they’re having an episode. They may not recognise you and may become more agitated if you try to comfort them.

    Your child won’t remember the episode the next morning, but it may still help to have a general chat to find out if anything is worrying them and triggering the episodes.

    It’ll also help if they have a relaxing bedtime routine.

    Try not to discuss the episodes with your child in a way that worries them as this may increase their anxiety.

    If the night terror episodes are frequent and occur at a specific time every night, you may find that waking your child breaks the cycle.

    Wake your child 15 minutes before the anticipated time of the episode every night for 7 days.

    This can disrupt their sleep pattern enough to stop the episodes without affecting sleep quality.

    Treatment For Night Terrors

    Understanding our sleep cycle: REM and non-REM sleep

    Although night terrors are scary and distressing, theyre unlikely to cause any permanent damage to children and adults. Further, the episodes pass without any intervention and even stop occurring altogether.

    However, if you believe that night terrors are having a significant effect on you or your child, then treatment may be necessary.

    Here are the three types of treatment options available:

    • Techniques to deal with stress
      • Relaxation techniques
    • Treatment of underlying medical conditions, such as depression or sleep apnea.

    What To Do And Not Do During A Night Terror

    Your biggest concern during a night terror should be your childs safety.

    Make sure that the bedroom environment is as safe as possible and remove furniture that is close to the bed, says Kapur.

    Some children remain in bed while others get out and thrash about. And while they may look like they know what theyre doing, they dont, which is why you need to watch out for them.

    Do not try to wake your child during a night terror. Doing so only confuses and disorients your child, and makes it likely that it will take them longer to settle back down and return to sleep.

    Also do not block or restrain your child unless it is absolutely necessary to do so to protect them, as this could trigger aggressive behavior.

    Night Terrors In Adolescents

    While detailed evidence is lacking, the prevalence of night terrors in children over 12 appears to be low. Most adolescents who have night terrors experienced them when they were younger and will outgrow these episodes as they move into adulthood. One study describes that only 4% of parasomnias like night terrors will persist past adolescence. New onset of night terrors in teenagers may be related to trauma or a psychiatric disorder.

    In certain social settings at this age, like sleepovers or summer camps, a teen with a history of night terrors may feel some anxiety or embarrassment. It may help to consult with a doctor to help identify triggers or other contributing health conditions.

    Sleep Cycles In Other Animals

    Sleep Cycles in Other Animals

    Humans may be unique in a lot of ways, but the fact that we sleep is not one of them. As discussed, sleep is important for recovery, memory storage, and growth, so it makes perfect sense that other animals need sleep, too.

    However, the length of sleep, brainâs state of consciousness, and whether dreaming occurs differs among species.

    But do all animals even sleep? Research has shown that birds and mammals sleep . That is, they become unconscious to their surroundings for a certain period of time. Reptiles sleep, but research is inconclusive regarding whether they reach a REM sleep-like state.

    Fish and amphibians reduce their state of awareness but do not ever become unconscious . Insects, on the other hand, do not appear to sleep , although they may experience periods of inactiveness .

    It is important to understand that while other animals also sleep, different types of animals have different sleep cycles. Birds and mammals share non-REM and REM sleep, but for birds, both cycles are much shorter â non-REM averages roughly two and a half minutes while REM lasts about only nine seconds .

    The length of these cycles also ranges from mammal to mammal. For example, REM sleep occurs for 24 minutes in the cat and 12 minutes in the rat .

    It is possible that reptiles dream, since past studies reveal they also exhibit some form of REM sleep , but researchers are still uncertain as to whether this is completely true.

    Sleep terrors sometimes can be triggered by underlying conditions that interfere with sleep, such as: Sleep-disordered breathing a group of disorders that include abnormal breathing patterns during sleep, the most common of which is obstructive sleep apnea. Restless legs syndrome.

    One may also ask, do fevers cause night terrors? The cause is unknown but night terrors are often triggered by fever, lack of sleep or periods of emotional tension, stress or conflict. Also, night terrors are most common in preadolescent boys, though they are fairly common in children three to five years old.

    Similarly, you may ask, do nightmares occur in REM sleep?

    Sleep is divided into two types: rapid eye movement and nonrapid eye movement . REM and non-REM sleep alternate in 90- to 100-minute cycles. Most dreaming occurs during REM sleep. Nightmares usually occur in the middle of the night or early morning, when REM sleep and dreaming are more common.

    Can You Prevent Night Terrors

    Getting your baby to sleep through the night is one of the great mysteries of parenthood, but a well-rested baby may be less likely to have night terrors.

    While this may sound like an impossible task, there are things you can do to encourage baby to get more zzzs.

    For starters, its important to know how much sleep your little one needs. The American Academy of Pediatrics suggests infants 4 to 12 months need 12 to 16 hours of sleep a day, including naps, 1- to 2-year-olds need 11 to 14 hours of sleep per day.

    But how can you get your baby to sleep for that long, especially if they are going through a developmental leap, are sick or teething, or have FOMO sleep aversions?

    One way to help your baby get more sleep is to introduce a consistent bedtime routine. The routine should be simple enough that any caregiver can do it, and something thats manageable for you to do each night.

    For example, your routine could involve brushing babys teeth or gums, reading them a book, and then tucking them in at the same time every night.

    For best results, start the bedtime routine before your baby starts rubbing their eyes, which is a sign of overtiredness.

    What Should You Do About Night Terrors

    Night Terrors In Children And How To Stop Them

    During a terror

    During night terrors, you should offer your child calm and gentle comfort, like a hand on their body. Perhaps a light squeeze of your hand. You may also need to gently restrain your child if they could potentially hurt themself.

    It is recommended that you do not attempt to wake your child. Because the child is quite likely disoriented, waking them will probably make them more upset and cause the terror to be worse for them.

    After a terror

    If you see that your child is having night terrors, you should keep a sleep diary that covers 1-2 weeks to determine if there is any pattern that can be found. Youll have to include anything that could be a possible trigger listed above in addition to the tracking of sleep. If you do plan to go to the pediatrician about sleep terrors, this is likely something theyll want you to do anyways.

    If you notice that your child is having terrors at approximately the same time each night, you could consider a pre-emptive awakening 10-15 minutes before the terror usually strikes. You will have to test a bit to see how much you have to wake the child to have an impact. Disrupting the sleep cycle could possibly help your child avoid a terror.

    Finally, you should probably also make the following changes that are applicable to see if there are improvements:

    Nrem Stage 2 Drifting Deeper Into Sleep

    Slower theta waves with sleep spindles and k-complexes

    Stage 2 is often considered the beginning of proper sleep. Since sleep is such a gradual process, its actually quite hard for researchers to properly define when someone has fallen asleep. Theres a very fine line between relaxing deeply and having fallen asleep.

    Its still a reasonably light stage of sleep. You could still quite easily wake someone up from stage 2, but unlike stage 1 they would know that they had just been sleeping.

    The key signs that show someone is in NREM stage 2 are:

    • Sleep spindles A burst of fast waves lasting for less than a second
    • K-Complexes A single long delta wave that lasts for just a second

    Its believed that sleep spindles and k-complexes are used by the brain to block out any harmless distractions and keep you sleeping.

    In this midway stage of sleep your body begins to prepare your body for the deep sleep ahead. Your heart rate slows, temperature drops and your brainwaves become slower. Your eyes are still and your muscles completely relaxed.

    Adults spend around half their sleep time in NREM stage 2. It lasts for around 10 to 20 minutes.

    Night Terror Treatment In Adolescents And Adults

    Adolescents and adults who experience repeated night terrors may benefit from working with a sleep specialist who can help to identify whether there is an underlying cause that can be treated. They may also prescribe therapy to manage the symptoms of night terrors.

    A doctor or sleep specialist may ask you to keep a sleep diary, which is a record of your recent sleep habits and how sleep is affecting your daily life. They may ask for information from a bed partner or family member who can describe night terror episodes. Some individuals may be referred for a sleep study to further evaluate and diagnose underlying/concurrent sleep disorders.

    How To Tell If Your Baby Is Having Night Terrors

    As a parent, you know that the phrase sleep like a baby doesnt actually describe the way most babies sleep. Between nighttime feedings, diaper changes, and baby sleep cycles, youre likely already very familiar with nighttime wakings. But during a night terror, although youll be wide awake, your baby is technically still asleep.

    The first time your baby has a night terror, you may initially think they are sick or experiencing a nightmare. But night terrors and nightmares are different.

    Night terrors start early in the nighttime sleep cycle when your baby moves from deep to light sleep. They can last for a few minutes or up to 45 minutes, and your baby will remain asleep during and after the episode. Nightmares happen later in the sleep cycle, and your baby may or may not wake up because of a nightmare.

    The following behaviors and symptoms may be a sign that your baby is having a night terror:

    • screaming
    • a racing heartbeat
    • rapid breathing

    Your baby may also not respond to your attempts to comfort or soothe them. Thats because, even if their eyes are open, they are still asleep.

    After the night terror, your baby will fall back into deep sleep and will be unable to recall the episode in the morning, no matter how vividly you remember it. This is untrue of nightmares, which your baby may remember upon awakening.

    Night terrors usually occur only once a night.
