Interactions Between Hormones And Behavior

Interactions Between Serotonin And Sleep Apnea

Rough definition of serotonin

The neurotransmitter serotonin (Enteramin or 5 HTP) is mostly present in the blood, gastrointestinal tract or central nervous system. Primarily it is known to impact the feeling of well being. Thus it is often named the "happiness hormone". 95% of the serotonin in the body is in the gastrointestinal tract. 90% helps the regulation of the intestinal movements in enterochromaffin cells where it is produced. The largest part of the remaining serotonin in the body is in the blood and in the central nervous system. Besides the regulation of intestinal movements it primarily regulates the tone of the blood vessels and signal transmission in the central nervous system.

How sleep apnea is influenced by serotonin.

Serotonin mainly impacts the nervous system, the gastrointestinal tract and the cardiovascular system.

1. How serotonin affects the cardiovascular system

Serotonin regulates the contraction and relaxation of blood vessels. For the kidney and lung the more important part is the contraction, while in the blood vessels themselves the relaxation plays the bigger role. It's a given that a malfunction in the cardiovascular system can cause disruptions that lead to sleep apnea. A change in serotonin levels in the blood has a direct affect on sleep apnea.

2. How the central nervous system is influenced

a. The feeling of well-being and mood changes

The best known effect of serotonin on the body is it's influence on moods through the central nervous system. At a serotonin level in the brain, that is too high, hallucinations and restlessness can be caused. Meanwhile depressions are often traced to low levels. Often bad aggressive temper and anxiety is also related to low serotonin levels.

IMPORTANT: An increased intake of serotonin rich food like chocolate or banana does not affect the serotonin level in the brain. The uplifting effect is due to the high level of carbohydrates that lead to an increase in the production of neurotransmitters in the brain.

b. Sleep-Wake Cycle

Since the 1950's it is known, that serotonin has a regulating effect on the sleep-wake cycle. However, the studies concerning the mechanisms of this regulatory effect have long been contradictory. Current studies show, that the wake periods are influenced by the activity of the serotonin containing neurons in the hypothalamus. The neurons are less active during sleep and almost inactive during the REM phase. Any change in the serotonin level will likely cause disruptions in the sleep-wake cycle and likely have an affect on the exposure to sleep apnea.

c. Breathing

The nerves that control breathing need a certain amount of serotonin in order to do communicate with the brain. An improperly-working serotonin system deprives the body of an adequate supply of the neurotransmitter, often resulting in sleep apnea. Also, serotonin receptors control the release of hormones such as cortisol. One role of cortisol is to help control the muscles needed for breathing.

Cases of sleep apnea that are based on a low serotonin level can be successfully treated with 5-HTP as part of the patient's medication (Dr. Murray in "5 HTP - The Natural Way to Overcome Depression, Obesity, and Insomnia").

It is recommended to take between 100 and 300 mg of 5-HTP before sleep. After taking 5-HTP sleep apnea patients sleep more soundly and awaken less, so Dr. Murray reports.

On one hand this is great news, but it should be very clear, that the intake of 5-HTP can not cure sleep apnea alone. It will always have to be combined with a set of other treatments that target obesity, breathing habits, lifestyle (alcohol/nicotine/narcotics) and so on. Consult your Doctor about the use of 5-HTP and other medication as well as interactions of the medicine you use.

Frequently Asked Questions

  1. QUESTION:
    Explain the interaction between hormones and behavior and how it affects the determination of gender identity?
    Explain the interaction between hormones and behavior and how this interaction affects the determination of gender identity. Evaluate biological psychology and environmental influences on sexual differentiation and gender identity.

    • ANSWER:
      Hormones only change your appearance not your behavior. Don't let people use that as an excuse to misbehave. Your soul is what does the thinking. Also, how you control your memories controls your behavior.

    Help me, please! (biology)..?
    1. Many homeowners who used to collect, bag, and discard grass clippings are now using mulching
    lawnmowers, which cut up the clippings into very fine pieces and deposit them on the soil.

Which statement best explains the behavior of these baby turtles?
    (1) More of the turtles’ ancestors who acted in this way survived to reproduce, passing this behavioral trait to their offspring.
    (2) The baby turtles are genetically identical, so they behave the same way.
