How does daylight savings time affect students?

Conclusions: The early March DST onset adversely affected sleep and vigilance in high school students resulting in increased daytime sleepiness. Larger scale evaluations of sleep impairments related to DST are needed to further quantify this problem in the population.

How does daylight savings WORK example?

The typical implementation of DST is to set clocks forward by one hour in the spring (“spring forward”), and to set clocks back by one hour in autumn (“fall back”) to return to standard time. As a result, there is one 23-hour day in late winter or early spring and one 25-hour day in autumn.

Why do we have Daylight Savings time?

Why do we still do it? DST is generally accepted as a way to save energy and daylight during the spring and summer months, as the ‘extra’ hour means people have more daylight hours to do outdoor activities and use less energy in their homes.

Why is daylight savings time unhealthy?

The shift raises stress levels and inflammation, shortens our sleep, and increases depression. In the week after daylight saving time begins, the incidence of heart attacks and strokes goes up significantly. A recent study found a 6 percent rise in fatal car crashes in that same period.

What is wrong with daylight Savings time?

Later sleep timing is associated with more substance use and physical and mental health problems, including obesity, depression and heart disease. It’s also associated with morning sleepiness, which contributes to accidents, poor work productivity and poor school performance.

What would happen if we got rid of Daylight Savings Time?

According to a 2020 University of Colorado study, the increase in fatal crashes is as high as 6% in the week immediately following the spring switch. Getting rid of this change could result in roughly 28 fewer American road deaths per year.

Why should we abolish daylight savings time?

Daylight saving time can disrupt our circadian rhythms, making us less alert and prone to illness or accident. Many sleep experts are calling for it to be abolished. In the meantime, a gradual shift in sleep schedule leading up to the time change may help minimize the effects.

What is the downside of daylight savings time?

For some, however, the time change can have more serious consequences to their health. Studies link the lack of sleep at the start of DST to car accidents, workplace injuries, suicide, and miscarriages. The early evening darkness after the end of the DST period is linked to depression.
