The Effects Of Trauma On The Body

Why do we get Nightmares? more videos | #aumsum #kids #science #education #children

When the brain anticipates a threat, it reacts quickly in order to protect itself from harm. An internal alarm system, called the stress response or the fight-flight-freeze response, triggers physiological changes throughout the body. A cascade of hormones are released, muscles tense, heart rate increases, and breathing becomes more rapid as the body prepares to defend against threats.

After the threat or traumatic experience has ended, the bodys stress response begins to return to baseline. Initial reactions vary and are all considered normal and healthy responses to psychological trauma. These reactions often include confusion, anxiety, physical arousal, and difficulty expressing emotions. Fortunately, humans are incredibly resilient and, for the majority of people, even the most challenging reactions to traumatic experiences will lessen with time as the body and mind integrate the experience and heal.

Some people experience delayed reactions after traumatic events. Delayed reactions may include depression, fatigue, nightmares, and even the development of sleep disorders. If these symptoms persist over time, or if they begin to interfere with work, school, or relationships, they may be a symptom of more severe post-traumatic stress.

How To Diagnose Nightmares

If you think you may have nightmare disorder,ask yourself the following questions:

  • Do you often wake up from sleep due to a disturbing dream?
  • Do these dreams evoke emotions of fear, anger, sadness or disgust?
  • Are you alert and able to think clearly as soon as you wake up?
  • Are you able to clearly recall details of these dreams?
  • Do these dreams often occur during the late portion of your sleep period, such as in the early morning part of your sleep?
  • Do you have difficulty falling back asleep after these dreams?

If you answered yes to these questions, you should talk to your doctor or see a sleep doctor. A sleep doctor is trained to accurately diagnose nightmare disorder and rule out any possible underlying causes or complications.

So There You Have It Because Of The Symptoms People Often Think That Dp Is Closely Related To Sleeping And Dreaming

But when you think about it, all anxiety-spectrum conditions have similar effects. Yes, DP might disrupt your sleep and cause nightmares — but so do all anxiety-based conditions. There’s nothing special about Depersonalization in that sense. It’s just another condition caused by anxiety. And just like with any other condition, your sleep and dreaming will get back to normal as you recover.

What Causes Problems With Sleep

The things that affect our sleep differ for everyone. They can include:

  • stresses or worries for example, issues with money, housing or work
  • problems with where you sleep for example, if you sleep somewhere uncomfortable or you’re easily disturbed
  • health conditions relating to sleep, also known as sleep disorders
  • being a parent or carer

For more information about sleep disorders, see the Mental Health Foundation and Royal College of Psychiatrists websites, and our list of useful contacts.

“It’s not possible to relax if you don’t have anywhere comfortable and safe at night. This leads to not sleeping and worrying most of the night.”

If problems with sleep are worrying you or affecting your day to day life, it’s a good idea to see a doctor who can give you a health check and help you access treatment and support. If you fill in a sleep diary, you could take this to your appointment to show your doctor.

“My sleep problems are more a case of bedtime procrastination than insomnia as such and, as a consequence, being too tired the next morning. I still haven’t found out what works for me as I can get to sleep once I do get to bed.”

Maintain Hydration Through The Day

Nightmares and Sleep

If you frequently find yourself thirsty at night, it might mean that you arent staying hydrated during the day. By maintaining hydration throughout the day, you have less to worry about when bedtime rolls around. Tips for healthy hydration include:

  • Sipping fluids regularly, including by setting a schedule reminder if you have a hard time remembering to drink water.
  • Using a water bottle to have a drink easily accessible and to track how much water youve consumed.
  • Drinking water as your primary beverage and being careful about the intake of sugary drinks like soda or juice as well as caffeinated and alcoholic drinks.
  • Eating a balanced diet with plenty of fruits and vegetables, which have higher moisture content and can increase your water intake from food.

Causes Of Dream Deprivation

Sleep deprivation has real impacts on health and well-being. The most obvious is sleepiness. Feeling sleepy can affect your work and family life. It can also make it dangerous to do things like drive a car.

Sleep deprivation also affects things like:

  • Metabolism
  • Pain
  • Heart health

Sleep has structure. REM sleep happens at regular intervals during the sleep period. This is typically every 90 to 120 minutes.

REM sleep may last 5 to 30 minutes. The periods of REM sleep usually become longer towards morning. This means most REM sleep happens in the last one-third of the night. When you wake, the last period of REM sleep may be interrupted.

If your REM sleep is often disturbed, you may have false awakenings. This is when you feel like you woke up but are actually still dreaming.

In some situations, you may spend less or no time in REM sleep. If you don’t get enough total hours of sleep, for example, that can lead to less REM sleep overall.

You may also spend a greater percentage of the night in REM sleep. This happens because you may not spend any time in lighter sleep. This is part of the sleep consolidation process, when you’re “catching up” on lost sleep.

Substance use has a strong impact on REM sleep. The following are known to suppress REM sleep:

During REM, the muscles relax. This may cause airway muscles to collapse. When this happens, it can trigger the breathing disturbances of sleep apnea. This can interrupt REM sleep.

Medications That Can Cause Nightmares

Sleep plays a major role in ones physical and mental health. From boosting your mood and helping with heart health to strengthening immunity and weight management, sleep has major benefits. Most adults need around seven to nine hours each night to get the full range of benefits. Nightmares are one factors that impact your quality of sleep. While nightmares are most often associated with children, adults can definitely experience them. One cause of your nightmares may be your medication. Below are some of the common medications that can cause nightmares.

My Partner Has Night Terrors Is There Anything I Can Do

If you live with or share a bed with a partner who has night terrors, there are a few things you can do to offer comfort and keep them safe.

Avoid trying to wake them up during an episode. You may not be able to wake them, but even if you can, they may become confused or upset. This could cause them to act out physically, potentially injuring both of you.

What you can do is be there to offer comfort without getting physically involved. Talk to them in a calm, quiet voice. If they get out of bed but arent aggressive, you can try gently guiding them back to bed. But back off as soon as you sense any hesitation or aggression.

If your partner feels embarrassed the next day when they hear about their behavior, try to offer reassurance and understanding. Explain that you know its out of their control.

Consider showing support by helping them keep track of episodes in a sleep diary or going with them to a therapist appointment.

Sleep Deprivation Stage : 36 Hours

The longer you go without sleep, the worse the stages of sleep deprivation becomes.

While even a little bit of sleep loss has a negative effect on the cardiovascular system, for instance, 36 hours without sleep can put serious pressure on your heart. Your blood pressure increases, and your heart rate increases too.

Additionally, your cognitive performance is likely to deteriorate. You may have trouble properly recalling faces, and your ability to remember words will be damaged.

Studies have found that as the levels of sleep deprivation progress, your ability to practice complex skills, like making verbs out of nouns, will go completely haywire.

Sleep Deprivation Stage : 48 Hours

The stages of sleep deprivation become even more worrisome when you reach 48 hours without sleep. At this point, your body is under a significant amount of excess stress.

Studies have found that the immune system of people missing out on 48 hours of sleep is usually drastically different from well-rested people. For instance, your levels of white blood cells fall dramatically, making it difficult for you to fight off disease.

A study of healthy people who had been deprived of sleep for 2 days found higher levels of nitrogen in the urine too. This indicates huge levels of stress in your body.

Additionally, your reaction time will be seriously impaired by this point. Youll struggle to keep yourself out of danger and be unable to make even the simplest decisions.

What Are The Health Effects Of Nightmares In Adults

Nightmares become much more than bad dreams when they have a significant effect on your health and well-being. Among people who experience nightmares, those who are anxious or depressed are more likely to be distressed about the experience and suffer even more psychological ill effects. Although the relationship is not understood, nightmares have been associated with suicide. Because nightmares may have a significant impact on your quality of life, it’s important to consult a medical professional if you experience them regularly.

Sleep deprivation, which can be caused by nightmares, can cause a host of medical conditions, including heart disease, depression, and obesity.

If nightmares in adults are a symptom of untreated sleep apnea or post-traumatic stress disorder, the underlying disorders can also have significant negative effects on physical and mental health.

Whats The Biology Behind The Adhd

ADHD sleep problems may be a side effect of impaired arousal, alertness, and regulation circuits in the brain. Other researchers believe that ADHD sleep problems can be traced to a delayed circadian rhythm with a later onset of melatonin production. Despite similarities between certain sleep disorders and ADHD symptoms, research has failed to find consistent sleep abnormalities in people with ADHD.

Some individuals find it easier to sleep with the calming effects of stimulant medications that are commonly prescribed for ADHD. However, for many people, stimulant medications cause a number of sleep problems in their own right. Co-existing disorders such as anxiety, depression, or substance abuse, as well as poor sleep hygiene, likely also play a role in sleep difficulties.

What Can Cause A Nightmare

Oversleeping can cause nightmares

Although there is still a debate about why we dream, there are a number of possible reasons why we may experience nightmares as we sleep. A primary risk factor can be stress and anxiety, with people suffering from chronic stress more prone to nightmare disorders. Further mental health issues such as depression and bipolar disorder can also increase the likelihood of a nightmare.

Potential causes include:

  • Medications affecting the nervous system
  • Illness or fever
  • Alcohol or drug use
  • Eating prior to bedtime

Sleep deprivation and sleep apnea can cause nightmares, specialists say. Genetics may play a role in how often you have a nightmare, with some people being genetically disposed to the problem.

What Is The Relationship Between Hydration And Sleep

Hydration is important for most systems of the body, which is why dehydration can have diverse symptoms, including effects on sleep.

People who are suffering from significant dehydration often find that they feel extremely tired, lethargic, or fatigued. Other symptoms of dehydration, such as headaches, dry mouth and nasal passages, and muscle cramps may cause discomfort that makes it harder to sleep well.

At the same time, excess hydration can contribute to sleeping problems. Frequent urination at night, known as nocturia, can interrupt sleep with repeated trips to the bathroom. Nocturia can be especially problematic for people who struggle to fall back asleep after getting up from bed.

There is also evidence that a lack of sleep may contribute to dehydration. In a study of nearly 20,000 adults in both the United States and China, people who slept only six hours per night were found to have significantly higher rates of dehydration than people who slept eight hours.

While this was an observational study and cannot prove causality, that the association existed in two distinct cultural contexts adds weight to the findings. In addition, there are potential biological explanations for why poor sleep can affect hydration.

If sleep is interrupted or cut short, though, this natural process may be disrupted, interfering with the hormonal signals for water retention. As a result, sleep deprivation may directly contribute to dehydration.

When Should You See A Doctor About Nightmares

Because its common to have an occasional nightmare, some people may find it hard to know when nightmares are a cause for concern. You should talk to your doctor about nightmares if:

  • Nightmares happen more than once a week
  • Nightmares affect your sleep, mood, and/or daily activity
  • Nightmares begin at the same time that you start a new medication

To help your doctor understand how nightmares are affecting you, you can keep a sleep diary that tracks your total sleep and sleep disruptions, including nightmares.

Whats The Connection Between Adhd And Sleep

Beginning around puberty, people with ADHD are more likely to experience shorter sleep time, problems falling asleep and staying asleep, and a higher risk of developing a sleep disorder. Nightmares are also common in children with ADHD, especially those with insomnia. Sleep problems in ADHD tend to increase with age, though sleep problems in early childhood are a risk factor for future occurrence of ADHD symptoms.

Even those who are rarely hyperactive during the day may experience racing thoughts and a burst of energy at night that interfere with sleeping. For some, nighttime presents the perfect opportunity to hyperfocus on a project, as there are less distractions. Unfortunately, this makes it difficult to settle down for sleep and it can lead to a disrupted sleep-wake schedule. Over time, insomnia may worsen as people start to develop feelings of stress related to bedtime.

Many people with ADHD experience daytime sleepiness and difficulty waking up as a result of poor sleep. Others experience restless, non-refreshing sleep with multiple nighttime awakenings.

Sleep problems in ADHD appear to differ depending on the type of ADHD. Individuals with predominantly inattentive symptoms are more likely to have a later bedtime, while those predominantly hyperactive-impulsive symptoms are more likely to suffer from insomnia. Those with combined hyperactive-impulsive and inattentive ADHD experience both poor sleep quality and a later bedtime.

How Common Are Nightmares

What is Nightmare Disorder?

They are extremely common, and may affect as many as 80-90% of people at some point in their lives. This phenomenon can begin as early as age 3, and are common in young children. They generally lessen as a person grows up, but most adults will also have them on occasion during their lives. They are common in both males and females.Nightmares as a chronic sleeping disorder are much less common, and affect about 5% of the population.

Some of these cases can be caused by medication use, or by extreme levels of anxiety in everyday life. There is also a slight increase in the chances of having them as a sleeping disorder if someone in your family has a similar problem. Sleep deprivation may also be a cause of nightmares, but whether this could lead to chronic nightmares is unverified.

Get Better Sleep With Bipolar Disorder

Disrupted sleep can really aggravate a mood disorder. A first step may be figuring out all the factors that may be affecting sleep and discussing them with your doctor. Keeping a sleep diary may help. Include information about:

  • How long it takes to go to sleep
  • How many times you wake up during the night
  • How long you sleep all night
  • When you take medication or use caffeine, alcohol, or nicotine
  • When you exercise and for how long

Certain bipolar medications may also affect sleep as a side effect. For example, they may disrupt the sleep-wake cycle. One way to address this is to move bedtime and waking time later and later each day until you reach your desired goal. Two other ways to handle this situation are bright light therapy in the morning and use of the hormone melatonin at bedtime, as well as to avoid bright light or over-stimulating activity near bedtime. This can include exercise and TV, phone, and computer screens.

Of course, your doctor may recommend a change in medication if needed. Be sure to discuss any other drugs or medical conditions that may be affecting your sleep, such as arthritis, migraines, or a back injury.

Restoring a regular schedule of daily activities and sleep — perhaps with the help of cognitive behavioral therapy — can go a long way toward helping restore more even moods.

Strange But True: Less Sleep Means More Dreams

Missing sleep tonight may just boost your dreams tomorrow night.

About three years ago Eva Salem got into some trouble with a crocodile. It snapped her hand in its jaws. In a panic, she managed to knock out the crocodile and free herself. Then, she woke up.

“I imagine that’s what it’s like when you’re on heroin. That’s what my dreams were likevivid, crazy and active,” she says. Salem, a new mother, had been breast-feeding her daughter for five months before the croc-attack dream, living on four hours of sleep a night. If she did sleep a full night, her dreams boomeranged, becoming so vivid that she felt like she wasn’t sleeping at all.

Dreams are amazingly persistent. Miss a few from lack of sleep and the brain keeps score, forcing payback soon after eyelids close. “Nature’s soft nurse,” as Shakespeare called sleep, isn’t so soft after all.

“When someone is sleep deprived we see greater sleep intensity, meaning greater brain activity during sleep dreaming is definitely increased and likely more vivid,” says neurologist Mark Mahowald of the University of Minnesota and director of the Minnesota Regional Sleep Disorders Center in Minneapolis.

Of course there is non-REM rebound as well, but the brain gives priority to the slow-wave sleep and then to REM, suggesting that the states are independent of each other.

But, given that rats run through dream mazes that precisely match their lab mazes, others feel that there must be some purpose or meaningful information in dreams.
