(CNN Spanish) — Clocks will go back one hour in the United States this Sunday, November 6, the date that marks the start of winter time 2022.
At 02:00 am on Sunday the 6th, the first Sunday of the month of November, the daylight saving time that began in March — known in English as “Daylight saving time” — comes to an end and the clocks must turn to 01 :00 am (Remember that those that are on a device with an internet connection generally adjust automatically, and for those that don’t, you may want to make the change before going to sleep so you wake up at the correct time.)
That day, therefore, you will gain an hour of sleep, the one you lost when you had to advance the clock on March 13.
In Hawaii, Puerto Rico, the territories of Guam, the Virgin Islands and American Samoa there was no change to daylight saving time, so it should not be adjusted now either. On the other hand, the states of the northern border of Mexico will be adjusted in accordance with the United States time.
The history of winter and summer time in the United States
Time changes are implemented with the aim of making the most of sunlight and reducing energy consumption. In the summer months, as there is sunlight for more hours, you can advance the clock and take advantage of it. But in winter it is necessary to go back to “standard time” in order to have relatively early sunlight. If this were not done, in some places the sun would not rise until almost 8:30 am
The current system followed by the United States began in 2007, but the concept of taking advantage of daylight is much older. Who originally came up with the idea is disputed, but it seems that Benjamin Franklin first mentioned it in 1784, when he wrote a letter to the editor of the Journal of Paris.
However, daylight saving time did not become widespread until more than a century later. Several countries, including the United Kingdom and Germany, applied daylight saving time during World War I. But the United States did not standardize the system until 1966, when it passed the Uniform Hours Act.
For years, the United States observed daylight saving time from the first Sunday in April to the last Sunday in October. In 2005, President George W. Bush extended daylight saving time by an additional four weeks, a change that officially went into effect in 2007.
In the United States, states are not required by law to observe daylight saving time, and in that framework Hawaii and also most of Arizona do not observe it. Other states, such as Florida and California, are working to follow daylight saving time throughout the year.
Plans are also moving forward in Congress to make daylight saving time permanent. In March 2022, the Senate unanimously approved a bill to this effect. For it to become a reality, it needs to be approved by the House of Representatives and promulgated by President Joe Biden. In any case, the measure would not enter into force until November 2023.
Time to implement a change in practices
Time changes are often at the center of the debate due to the costs they can cause in human terms.
The changes disrupt our sleep schedules and harm our health, according to experts at the American Academy of Sleep Medicine. The impacts are wide-ranging and include bad news for cardiovascular health, possible stroke and atrial fibrillation, medical errors, mental health problems, and even traffic accidents.
Many people look forward to the extra hour of sleep that comes with the change to daylight saving time, but it’s not enough to erase chronic sleep debt, Dr. Kannan Ramar, a professor of medicine at the Center for Sleep Medicine, told CNN. from the Mayo Clinic in Rochester, Minn.
However, the extra hour of rest can make you wake up feeling more refreshed, which can motivate you to sleep more.
This is a good time to implement healthy “sleep hygiene” practices, which will help you fall asleep faster and stay asleep. Here we explain how you can do it.
