Sleep is for both the body and mind. The Hemi-Sync sleep CD package
offers you an opportunity for a refreshing nap and a sound REM state
sleep. Without sufficient REM (rapid eye movement) dreaming states
you wake up feeling tired, cranky and are unable to meet the challenges of
life. Catnapper - Mind Food® - Enjoy a totally refreshing nap in only 30 minutes. Verbal guidance and Hemi-Sync provide you with a unique opportunity to obtain deeply revitalizing rest. Benefit from Catnapper's proven effectiveness during work or study breaks or to re-energize for the evening. Also effective for countering the effects of jet lag, coping with irregular schedules or as the ultimate pick-me-up anytime. Deep 10 Relaxation - Mind Food® - Abandon your cares as verbal guidance and Hemi-Sync transport you to a blissful state of total relaxation followed by natural, restful sleep. Deep 10 Relaxation is a highly effective, time-proven means to counteract the negative effects of stress in your life. Anxiety and daily concerns seem to flat away as you move into progressively deeper states of mental and physical calm. Track 1 contains verbal guidance. Track 2 contains your sleep cycle without words. Use Deep 10 Relaxation to rejuvenate both mind and body and leave your cares behind. (Side 1 - Verbal/Side 2 - non-verbal). Restorative Sleep - Human Plus - Easily enter into a deeply, restorative sleep and support the process of healing. Use to assist your recovery from illness, injury, or surgery or to support the normal functioning of physical systems. Get a good night's sleep and wake up rested and refreshed.

Primary Sleep Disorders are those in which none of the etiologies listed below (another mental disorder, a general medical condition, or a substance) is responsible. Primary Sleep Disorders are presumed to arise from endogenous abnormalities in sleep-wake generating or timing mechanisms, often complicated by conditioning factors. Primary Sleep Disorders in turn are subdivided into Dyssomnias (characterized by abnormalities in the amount, quality or timing of sleep) and Parasomnias characterized by abnormal behavioral or physiological events occurring in association with sleep, specific sleep states, or sleep-wake transitions). Five distinct sleep stages can be measured by polysomnography: rapid eye movement (REM) sleep and four stages of non-rapid eye movement (NREM) sleep states 1, 2, 3, and 4.) Stage 1 NREM sleep is a transition from wakefulness to sleep and occupies about 5% of time spent asleep in healthy adults. Stage 2 NREM sleep, which is characterized by specific EEG waveforms (sleep spindles and K complexes), occupies about 50% of time spent asleep. Stages 3 and 4 NREM sleep (slow-wave sleep) are the deepest levels of sleep and occupy about 10%-20% of sleep time. REM sleep, during which the majority of typical story-like dreams occur, occupies about 20%-25% of total sleep. These sleep stages have a characteristic temporal organization across the night. NREM stages 3 and 4 tend to occur in the first one-third to one-half of the night and increase in duration in response to sleep deprivation. REM sleep occurs cyclically throughout the night, alternating with NREM sleep about every 80-100 minutes. REM sleep periods increase in duration toward the morning. Human sleep also varies characteristically across the life span. After relative stability with large amounts of slow-wave sleep in childhood and early adolescence, sleep continuity and depth deteriorate across the adult age range. This deterioration is reflected by increased wakefulness and stage 1 sleep and decreased stages 3 and 4 sleep. Polysomnography is the monitoring of multiple electrophysiological parameters during sleep and generally includes measurement of EEG activity, electrooculographic activity, and electromyographic activity. Additional polysomnographic measure may include oral or nasal airflow, respiratory effort, chest and abdominal wall movement, oxyhemoglobin saturation, or exhaled carbon dioxide concentration; these measures are used to monitor respiration during sleep and to detect the presence and severity of sleep apnea. Measurement of peripheral electromyographic activity may be used to detect abnormal movement during sleep. Most polysomnographic studies are conducted during the person's usual sleeping hours-that is, at night. However, daytime polysomnographic studies also are used to quantify daytime sleepiness. The most common daytime procedure is the Multiple Sleep Latency Test (MSLT), in which the individual is instructed to down in a dark room and not resist falling asleep; this protocol is repeated five times during the day. Sleep latency (the amount of time required to fall asleep) is measured on each trial and is used as an index of physiological sleepiness. The converse of the MSLT is also used: In the Repeated Test of Sustained Wakefulness (RTS) the individual is placed in a quiet, dimly lit room and instructed to remain awake; this protocol is repeated several times during the day. Again, sleep latency is measured, but it is used as an index of the individual's ability to maintain wakefulness. Sleep continuity refers to the overall balance of sleep and wakefulness during a night of sleep. "Better" sleep continuity indicates consolidated sleep with little wakefulness; "worse" sleep continuity indicates disrupted sleep with more wakefulness. Specific sleep continuity measures include sleep latency - the amount of time required to fall asleep (expressed in minutes); intermittent wakefulness - the amount of awake time after initial sleep onset (expressed in minutes); and sleep efficiency - the ratio of actual time spent asleep to time spent in bed (expressed as a percentage, with higher numbers indicating better sleep continuity). Sleep architecture refers to the amount and distribution of specific sleep stages. Sleep architecture measures include absolute amounts of REM sleep and each NREM sleep stage (in minutes), relative amount of REM sleep and NREM sleep stages (expressed as a percentage of total sleep time), and latency between sleep onset and first REM period (REM latency).
