    Muscle Paralysis In Dreaming Sleep, Mechanism Identified

    Scientists have discovered what goes on when the brain mediates in inhibiting the critical breathing muscles during REM (rapid eye movement) when a person is sleeping, a report published in the Journal of Respiratory and Critical Care Medicine revealed.</B>

    The authors, from the University of Toronto, Canada, explained that during REM sleep, there is a profound inhibition of muscle activity. This inactivity can affect the breathing muscles and is a cause of snoring and other breathing problems in sleep, as occurs in obstructive sleep apnea.

    The researchers say that their findings could pave the way for new treatments for sleep-related breathing problems.

    Co-author, Richard Horner, PhD., said "This paralysis affects breathing muscles and is a cause of snoring and other breathing problems in sleep, especially obstructive sleep apnea."

    Sleep apnea is a common sleeping disorder, and may increase the risk of strokes, heart attacks, hypertension, diabetes and daytime drowsiness.

    Dr. Horner said "The brain mechanism mediating inhibition of the critical breathing muscles in REM sleep was unknown, but a novel and powerful inhibitory mechanism is identified for the first time in our study."

    PhD student Kevin Grace performed a study on rats as they went through sleep-wake states.

    The tongue must remain relatively active during sleep, because this "breathing muscle" keeps the airspace open so that we can breathe while we sleep. If tongue muscle activity is inhibited during sleep, it can slide backwards and close up the airspace, making breathing harder.

    If the airway is blocked the sleeper experiences sleep apnea - episodes of self-suffocation. This resolves rapidly because the sleeper wakes up. In some cases of sleep apnea, there may be hundreds of episodes each night.

    I have experienced it for a while,that happens because of the weakness of muscles.You don't need to take stress all you need to do is make yourself psychically well.Make yourself active walk at least 1 hour day do exercising that will make your muscles strengthen.

      That is no big deal that is muscles weakness you need to make them strengthen to workout for you lower body.Go for cycling,swimming,running that will surely help you in getting rid of it.Just make your life active.

        Unfortunately, strengthening the lower body, while healthy, will not strengthen the muscles in the tongue and throat and so it will not help this specific element of OSA.
