In healthy sleep all the organs in our body can rest and regenerate. In order to fulfill the essential number of regenerating sleep cycles the average adult needs 7-8 hours. A five stage sleep cycle repeats consistently throughout the night. One complete sleep cycle lasts about 90 minutes. So during an average night’s sleep (8 hours), an adult will experience about four or five cycles of sleep.
History of Daylight Saving Time
The concept of setting the clocks ahead in the spring in order to make better use of natural daylight was first introduced in the US by inventor Benjamin Franklin in 1784.
During his time as an American envoy to France, Ben Franklin, publisher of the old English proverb, “Early to bed, and early to rise, makes a man healthy, wealthy and wise” anonymously published a letter suggesting that Parisians economize on candles by rising earlier to use morning sunlight.
This 1784 satire proposed rationing candles and waking the public by ringing church bells and firing cannons at sunrise.
US President Franklin D. Roosevelt instituted year-round DST in the United States, called “War Time” during World War II from February 9, 1942 to September 30, 1945. The change was implemented 40 days after the bombing of Pearl Harbor and during this time, the U.S. time zones were called “Eastern War Time”, “Central War Time”, and “Pacific War Time”. After the surrender of Japan in mid-August 1945, the time zones were relabeled “Peace Time”.
Congress decided to end the confusion and establish the Uniform Time Act of 1966 that stated DST would begin on the last Sunday of April and end on the last Sunday of October. However, states still had the ability to be exempt from DST by passing a local ordinance. (The exceptions to DST are Arizona, Hawaii, Puerto Rico, the Virgin Islands, and American Samoa.)
