The primary causes of sleep deprivation are advanced technology and electronics as well as work and family demands. The availability of television, radio, internet, smartphones, tablets, texting and video gaming provide constant stimuli that may be interfering with sleep. Making a habit of staying up late (or getting up very early) and "pulling all-nighters" are viewed as badges of honor in some circles, but are not providing any health benefit. Ever notice how many people fall asleep at their desks or on a plane or train during the day? People who have an adequate amount of sleep should not fall asleep during daytime hours.
