We lose an hour when Daylight Saving Time (DST) begins. We gain an hour when it finishes. So, how does the DST transition work? In the spring, Daylight Saving Time robs us of an hour of sleep. It gives back an hour in the fall. So, if it's 7 a.m. now, then it'll be 8 a.m. on March 27th. During this time, set your clock one hour ahead.
However, there is a bug in the algorithm used by most countries to decide when and if they should switch over to DST. This means that, from time to time, people have to wake up early or stay up late to make sure they're not missing their hour of sleep.
For example, before Mexico made the switch in October 2015, people in Mexico had to get up an hour earlier than normal to catch their hour of sleep. After Mexico made the switch, people in Puerto Rico also had to get up an extra hour to catch their hour of sleep. The United States will make the switch next year. People in Arizona, Colorado, Indiana, Iowa, Kansas, Maine, Montana, Nevada, New Hampshire, North Dakota, Oklahoma, South Carolina, Utah, Vermont, Washington, and Wisconsin will all have to get up an hour early.
So the first day of DST is not recommended for anyone who wants to stay healthy or happy.
Sleep is important because without it, we can't function properly. When we don't get enough sleep, we feel tired and run-down. We make bad decisions often caused by fatigue. We also seem to be more likely to injure ourselves when we are not getting proper rest. For example, when people go without sleep for a few days they become much more likely to die in car accidents.
So if you start DST early, you're going to feel like garbage the next day. That's why most countries/states that use DST don't start until late March or early April. That gives you plenty of time to get used to the idea of losing an hour of sleep.
Daylight Saving Time (DST) Typically, regions that adopt daylight saving time advance clocks by one hour towards the start of spring and return them to regular time in the autumn. DST, in effect, causes an hour of lost sleep in the spring and an hour of increased sleep in the fall. The adjustment helps reduce energy use - computers don't need more power used at night, and turning off lights is easier when it's not dark yet out.
During daylight saving time, people are less likely to use electricity at night, which means that fewer appliances need to be turned on. This reduces the strain on the power grid that allows for it to be more efficient during non-peak times. Because more people are sleeping later, breakfast eating habits have also changed with more people eating meals away from home during this time.
During standard time, we lose an hour of sleep in the spring and gain an hour in the fall. This arrangement avoids shifting work hours forward or back by more than one hour every year. It also avoids changing the clock during winter months, when days are longer but nights are still cold. However, some research has shown that these annual adjustments may not be as beneficial for health as once thought; some studies have shown that the risk of traffic accidents increases during DST transitions.
This is the first day of Daylight Saving Time. We lose an hour of sleep, but get an hour of daylight as a result. Daylight Saving Time has been practiced for millennia. Prior to the invention, most countries used solar time, which is based on the location of the sun in the sky. This would cause problems if someone had to move clocks ahead or back every year depending on the season. Since the 1920s, however, most countries have used electric light during their Daylight Savings periods, which allows for an annual adjustment without confusion or conflict.
People used to worry about losing sleep due to the spring forward change. Recent studies have shown that people can stay awake for almost a day after applying the clock forward. They also report feeling more energetic and having better moods. These benefits may come from getting out of bed earlier and thus experiencing more sunlight during the daytime. The evening shift loses money because they need more sleep, so this isn't beneficial for them. Children may suffer from staying up too late - one study showed that teenagers who went straight from school into darkness experienced delayed sleep phase syndrome. Those who went to bed later did not experience such problems.
The switch back over at the start of October means that people will once again be losing sleep. This time around, though, they're losing an hour of sleep rather than gaining one. Some countries hold on to the lost hour through November, while others drop it immediately after the start of Daylight Saving Time.
On the second Sunday in March, the United States begins Daylight Saving Time at 2:00 a.m. and returns to regular time on the first Sunday in November. Each time zone in the United States changes at a different time. Almost everyone anticipates "falling back" and grabbing that additional hour of sleep in the autumn. But does it actually happen?
Research published in 2004 by the U.S. National Institute of Health suggests that we do lose an hour of sleep per day in October and November. The study also noted that people tend to need more sleep during these months, so perhaps this is why they say we need more sleep in fall and winter. The study's conclusion was based on data from two large studies conducted between 1986-1994 and 1994-2003. Participants were asked to wear actigraphs (devices that measure sleep by tracking body movements) for one week during each season. They reported average hours of sleep per night and identified times they went to bed and woke up during each season. They were also asked to estimate how many hours of sleep they needed daily to feel well rested.
After analyzing the data, the researchers concluded that we need about 1 hour less sleep per day in October and November compared to other seasons. However, they also noted that people tend to need more sleep during these months, so perhaps this is why they say we need more sleep in fall and winter.
