In adults, blood pressure is considered normal if the top number (systolic pressure) is between 90 and 120 and the bottom number (diastolic) is between 60 and 80. There are several classes of blood pressure medications. Each class lowers blood pressure in a different way.
For other uses, see Narcolepsy (disambiguation). Narcolepsy is a long-term neurological disorder that involves a decreased ability to regulate sleep-wake cycles. Symptoms include periods of excessive daytime sleepiness that usually last from seconds to minutes and may occur at any time.
Most people with narcolepsy find a brief nap refreshing, with improved alertness for one to three hours afterwards. Naps should be limited to 15â20 minutes, as it can be difficult to wake from the deep sleep of a long nap, and an extended nap in the afternoon may make it harder to fall asleep at night.
