That would also include the cost of electrical connections for the jetted tub. I'd also be curious to know the difference in water usage & water heating cost, per additional inch depth of a tub (starting with some standard depth), if someone takes a long bath twice a week.
Sleep. For many of us, sleep is the sweet balm that soothes and restores us after a long day of work and play. But for those for whom sleep is elusive or otherwise troubled, the issue is far more fraught. Most people, at some point in their lives, experience difficulty falling asleep. Other parasomniasâsuch as sleep apnea, night terrors, narcolepsy, and sleep paralysisâare surprisingly common. The good news is that treatment of sleep disorders is progressing rapidly, with new advances appearing every month.
Polysomnography monitors your sleep stages and cycles to identify if or when your sleep patterns are disrupted and why. The normal process of falling asleep begins with a sleep stage called non-rapid eye movement (NREM) sleep. During this stage, your brain waves, as recorded by electroencephalography (EEG), slow down considerably. Your eyes don't move back and forth rapidly during NREM, in contrast to later stages of sleep. After an hour or two of NREM sleep, your brain activity picks up again, and rapid eye movement (REM) sleep begins. Most dreaming occurs during REM sleep. You normally go through four to six sleep cycles a night, cycling between NREM and REM sleep in about 90 minutes.
