Nightmare can be a sign of disease

A series of studies show that frequent nightmares can provide important clues about the health of the employer and even early warning of a potential illness, sometimes every year. before the disease symptoms appear.

Last month, researchers found that frequent childhood nightmares may be an early warning sign of neurosis later in life. The follow-up of 6,800 children showed that children who often have bad dreams (2-3 times a week) between the ages of 2 and 7 are at risk of developing a neurosis, such as hallucinations or illusions, when entering the youth stage, it is 3.5 times higher than other teenagers.

According to experts, frequent nightmares may imply, the child is facing psychological trauma, such as abuse or bullying, in real life. They can also be the result of playing games or watching violent TV shows near bedtime.

The neuroscience professor Patrick McNamara of Harvard Medical School emphasized that people can experience the dreadful dangers of nightmares to practice how to deal with them when awake. However, nightmares can also refer to some potential physical problem, disturbing sleep when we dream.

Humans dream only of rapid eye (REM) sleep, not deep. On average, each person experiences REM stage 4-5 times per night. Many health problems interfere with sleep, making you more likely to awaken during REM and remember having a nightmare.

For example, frequent nightmares can be a sign of sleep apnea. This disease makes breathing temporarily stopped due to blocked airways. Patients with sleep apnea often report nightmares.

A study published in 2012 in Sleep Medicine found that when patients treated sleep apnea by wearing a mask that forced the air gently into the airway, 91% of them were stop having nightmares. Sleep experts say that it is the stuffs and oxygen depletion that go to the brain when sleep apnea can increase the occurrence of nightmares.

Frequent nightmares may also involve heart problems. Specifically, people who frequently experience bad dreams are three times more likely to experience abnormal heart rhythms, according to a study published in the Netherlands Journal of Medicine in 2003. Chest pain also increased. 7 times the frequency of nightmares in a person.

Another theory is that people with heart disease, especially heart failure (the heart does not pump enough blood to the lungs and other organs), have difficulty breathing at night, making them easy to wake up. Sleep at REM sleep and remember nightmares.

In addition, any form of infection, from a serious cold to a kidney infection, can make nightmares more easily present . As we know, sleep is divided into 4 "non REM" stages and then 1 REM stage. In the early stages, people experience slow wave sleep, when our immune system is restored and strengthened.

When an infection occurs, whether or not a fever occurs, the body needs more slow sleep waves, so that the immune system can fight off the germ. However, it also brightens the REM sleep phase, delaying the time when we begin to enter the dream phase, leading to the appearance of nightmares or nightmares.

Frequent violent nightmares may be an early warning sign of Parkinson's disease, before symptoms actually show up for 10 years, according to Dr. Robert Brenner, neuroscientist at the Bushey Spire Hospital. (Brother).

Migraines also often occur after unpleasant dreams, involving anger, aggression and risk. Many women have reported experiencing more bizarre dreams around the time of menopause or menstruation, due to changes in hormones in the body that cause fatigue and interruption of sleep.
