This beautifully illustrated chart defines sleep and the sleep-wake cycle, explains why the body needs sleep, and describes the role of the suprachiasmatic nucleus (SCN) of the brain in sleep and wake regulation. The chart graphs and describes the five phases of sleep and covers common sleep disorders such as insomnia, obstructive sleep apnea, restless legs syndrome (RLS), and narcolepsy. Tips for a good night's sleep are also included.
Unmounted - Printed on high-quality heavy paper appropriate for framing. (Note: Unmounted charts cannot be displayed on the chart stands.)
Laminated - Printed on high-quality paper with flexible 1.5 mil plastic lamination. Metal eyelets in each top corner for convenient wall hanging or for use with chart stands. Lamination also makes the chart "markable" allowing write-on / wipe-off. Easily rolls up for portability. This is the most popular mounting.
