How much sleep a person needs constantly changes through a person's life: newborns require 16-18 hours, preschoolers 10-12, schoolaged children at least 9, while adults on average need around eight hours of sleep. The handbook also discusses snoring and sleep disorders such as insomnia, sleep apnea, restless legs syndrom, narcolepsy, and parasomnias. About half of all adults snore and African Americans, Asians, and Hispanics are more likely to snore loudly and frequently compared to Caucasians. Alcolhol and sedative taken before going to bed promote snoring.
