I convey a theory that inwards Europe people who alive inwards the northern countries larn to bed far before than those who alive inwards southern Europe. The to a greater extent than protestant, dour northern Europeans caput off to a bed early. At just the same fourth dimension those Roman Catholic, fun-loving Europeans inwards the southward are but leaving domicile for that evening's fiesta.
For but about argue I assumed that at that topographic point would hold upward a similar north-south dissever inwards the USA. However it turns out that inwards the U.S. at that topographic point is to a greater extent than of an east-west split. Jawbone has released an interactive map of Average Bedtime past times U.S. County. You tin run across on the map to a higher house that at that topographic point seem to hold upward distinct bands of similar bedtimes running due east to due west across the country.
Jawbone has a reasonable explanation of this trend. They believe that this tendency is caused past times time-zones. If y'all await at the borders betwixt Eastern Time as well as Central Time y'all tin clearly run across that at that topographic point is a marked departure inwards the times when people larn to bed on either side of the border. Jawbone fighting that if people either side of the edge "go to bed four hours after the Sun goes down, their clocks volition state that the somebody inwards Eastern Time went to bed i hr afterward than the somebody inwards Central Time".
There are but about obvious exceptions to this rule. For example, inwards well-nigh major cities as well as inwards college towns bedtimes tend to hold upward a piddling afterward than the norm for people who alive elsewhere on the same longitude.
This exception is likewise apparent inwards the seat out of hours Americans sleep. Jawbone has likewise released a map of the Total Hours of Night Sleep past times U.S. County. This map shows that inwards no major urban essence inwards the USA create well-nigh of the citizens larn the recommended 7 hours of slumber a night.
