Do you like to stay up late at night (possibly ALL night), or do you prefer getting up in the wee hours of the morning when the roosters crow? There is a big difference - - as those of you who are one or the other know.
Late night people have no difficulty staying wide awake after midnight. They relish their time alone and working undisturbed. On the other hand, early morning people have no difficulty waking up (and getting quality work done) when most others are still sound asleep.
According to an article written by Melinda Beck that appeared in the Wall Street Journal on March 4, 2008, studies have shown that "night owls" are more creative, more flexible, and more caffeinated; whereas, "early morning people" are healthier, more conscientious and more emotionally stable. The latter group are "not much fun at parties, but they run the world."
The problem arises when circumstances force one type of person to switch to become the other type. For example, when an early morning person gets a new job that is a Night Job; or, a late night person's company switches them to an early morning schedule.
In extreme cases, night owls who stay up late, and need to sleep even later, are said to have "Delayed-Sleep Phase Disorder." Extreme morning larks, who wake up before dawn and struggle to stay up past 8:00 p.m. have "Advanced-Sleep Phase Disorder."
Each extreme type either find careers that can accommodate them, or struggle to conform and often live sleep-deprived.
It appears that each extreme has a different chronotype that is partly genetic and partly due to environment cues.
Apparently, whole industries exist to help shift-workers adjust to working odd schedules. There are sleep clinics that help people with circadian rhythm disorders get back in sync.
Light seems to be a key factor in the body's circadian clock, which is centered in a tiny cluster of neurons behind the optic nerve. These neurons receive light signals from the retina and, in turn, send signals to the pineal gland, which regulates melatonin - - the hormone what makes us sleep. Darkness triggers the release of melatonin, while light suppresses it.
Natural light appears to be the most powerful, but artificial light in the evening also delays melatonin and slows down the circadian clock.
So a key part of one's sleep pattern may involve regulating light. So, night owls might want to start dimming the surrounding lights in the evening hours to help them go to sleep at an earlier hour. Also, they should give up coffee after 6:00 p.m., and cut out alcohol- - which can disrupt sleep. And, a cool, dark, quite place to sleep, free of cell phones, BlackBerries, text messaging, TV's, etc. helps one get an earlier, better night's sleep.
Experts say that the human body needs approximately seven to eight hours of sleep a night to maintain optimal alert levels during the day. The idea that many people need just four or five hours of sleep a night appears to be a myth.
Sleep deprivation has been shown to impair memory, weaken the immune system, slow metabolism and spur insulin resistance, a precursor to diabetes.
So, we lawyers, who often brag about our "all nighters" in the office, had better wise up if we want to be in it for the "long haul."
