I have spent the past two hours updating blogs and websites. At this point, on a Sunday morning, I am feeling sleepy. Perhaps too sleepy to get a Coke Zero out of the fridge and check my laundry.
Last night I got 7 hours of sleep. Isn’t that an average number?
According to the National Institute of Neurological Disorders (NIND) ,the amount of sleep each person needs depends on many factors, including age. Infants generally require about 16 hours a day, while teenagers need about 9 hours on average. For most adults, 7 to 8 hours a night, although some people can get by with 5 hours while others need 10. I once heard that Donald Trump sleeps 4 hours a night.
The need for sleep accumulates. This means that getting too little sleep creates a “sleep debt,” which is much like being overdrawn at a bank. Eventually, your body will demand that the debt be repaid. We don’t seem to adapt to getting less sleep than we need; while we may get used to a sleep-depriving schedule, our judgment, reaction time, and other functions are still impaired.I know that when I’m preparing for an event such as a fundraiser I’ll survive well on little sleep just prior to the event. The day after the event I’ll sleep for 10 hours.
Experts say that if you feel drowsy during the day, like now, you haven’t had enough sleep. If you routinely fall asleep within 5 minutes of lying down, you probably have severe sleep deprivation, possibly even a sleep disorder.
They say that sleep is necessary for our nervous systems to work properly. Too little sleep leaves us drowsy and unable to concentrate the next day. It also leads to impaired memory and physical performance and reduced ability to carry out math calculations. If sleep deprivation continues, hallucinations and mood swings may develop.
So, I guess I’ll have to fit a nap in to my schedule today so I don’t start hallucinating. I’m going to get that Coke, rotate my laundry and pay some bills first though.
