Slumbered Sleep

2.1 Sleep
Disruptions

Jet lag is also a circumstance that affects humans’
circadian rhythm and has become common
due to the massive increase in overseas
travel.
Substances like caffeine, nicotine,
alcohol, and narcotics, which are
frequently ingested in attempts to either
maintain alertness and arousal
or to seek slumber and calm, are
still other elements that interfere
with regular sleep/wake rhythms.

The day night cycle and circadian rhythms are
constantly out of sync when someone works
night shifts. It has been demonstrated that such
a discord between behavioral and physiological
circadian rhythms results in sleep loss and daytime
sleepiness as well as negatively affecting
safety, health, and mental function.
Technology advancements are also
strongly linked to other aspects
of contemporary living that affect
sleep, such as electronic media devices
like televisions and computers,
which allow for and even encourage
staying up longer.
Sleep deprivation and disruption
are also linked to lifestyle changes
in food and physical activity routines
as well as the rising incidence of
obesity in today’s culture. (Shochat,
