Sleep and Immune System

Sleep and sleep-related problems play a role in a large number of human disorders. Generally speaking, human disorders, which primarily related to sleep and sleep problems, are so many that they affect almost every field of medicine. Let me give you an example: stroke, (that is a sudden blockage or rupture or blood vessel in the brain with loss of consciousness, partial loss of movement, or loss of speech), as well as asthma attacks, more frequently happen during nights and early mornings. Medical researches suspect rapid changes in hormones or in a heart rate, and some other things more often associated with sleep attributes (like quality, property, or characteristic) could lead to those attacks.

Certain sleep stages, like REM sleep for example, prevent epilepsy seizures that could originate in one part of the brain and eventually spread over to other areas. On the contrary, deep sleep sometimes disperses these seizures. Another negative result occasionally produced by sleep deprivation triggering similar seizures in people being tested for epilepsy. Sleep also, as you can see affects epilepsy in abnormal ways. We know now that our immune system depends on close interaction with neurons that control sleep. We also identify our tendency felling sleepy or even falling asleep especially when we are sick. It could be explained by the presence of cytokines, the chemicals our immune system produces while fighting an infection, They are very powerful sleep-inducing chemicals. For millions of years our body has learned how to use sleep to conserve heat balance, energy, and other internal resources for our immune system to control any eruption in body and brain condition.

Watch how sleep reduction can be detrimental to the heart problems. Douglas Livornese, MD from Monmouth Pulmonary Consultants & Comfort Sleep Center interviewed about sleep deprivation causing heart disease:

Sleep and Mental Disorders

It is a well know fact that problems with sleep exhibits in almost all people with mental disorders, including those with depression, mania, phobia, and schizophrenia. Here is the most popular symptom of some sort of depression observed in people aver 50: they are often inclined to awake after a couple of hours being asleep at night. However, they find themselves unable to get back to sleep. It also has been observed the symptoms of mental disorders coincide with amount of sleep a person gets. Strangely enough, a very effective therapy for people with certain types of depression is a sleep deprivation. At the same time, sleep deprivation could actually cause depression in other people. Another dangerous area of extreme sleep deprivation becomes a principle cause of a seemingly psychotic state of paranoia and in healthy people. In addition, disrupted sleep can trigger episodes of mania, such as hallucinations, agitation and hyperactivity, in people with manic depression.

Sleeping problems are not strangers in many other illnesses as well, such as stroke, cancer, Alzheimer’s disease, and head injury. may arise from Rapid changes in the brain regions and neurotransmitters that control sleep are attributed to these sleeping problems. Those problems are also bi-products from drugs administered for other type disorders. People admitted to hospitals and who are normally receiving a round-the-clock care, treatment schedules, or regular hospital routines, most of the time demonstrates disruption of sleep. Here is a very old joke, which tells us a story about a patient who was awaken by a nurse giving him a sleeping pill. In reality, as soon as a sleeping problem develops, it usually added to a patient’s overall illness and causes upset mood, irritation, confusion, frustration, hypochondria, or even depression. Patients with falling asleep problem also complain more often about pain more usually requesting extra pain medication.

This is advice to medical practitioners:  please pay more attention to patients with sleeping problems who have other disorders. Your could definitely improve these patients’ health and quality of life.

 Sleep Disorders

At least 40 million Americans and Canadians suffer from chronic, or long-term, sleep disorders each year. They are those who turn to their family doctors. Another 20 million experience occasional sleeping problems. They also complain about it along with some other symptoms. These disorders and the resulting sleep deprivation interfere with their duties, work they do, driving habits, family, parenting, and social activities. They also spent an estimated $16 billion in medical costs each year. The indirect costs accounted for lost productivity and other factors are probably much greater. Medical doctors, sleep clinics and sleep researches have described more than 70 sleep disorders. Most of those disorders can be easily managed and effectively controlled once they are correctly diagnosed and timely identified, maybe even totally prevented.

 The most common sleep disorders include insomnia, sleep apnea, restless legs syndrome, and narcolepsy
