Spring Forward, or Daylight Saving Time, is the annual practice of turning clocks forward by one hour. While this results in an extra hour of sunlight, it also means losing an hour of sleep. This disruption to our sleep schedules can have adverse effects on our health and well-being, including increased risks of accidents, cardiovascular issues, mental health problems, and even miscarriages in pregnant women who conceived through IVF. The transition to longer days and darker mornings can also affect our internal body clocks or circadian rhythms, leading to sleep deprivation and social jet lag. Understanding the impact of Spring Forward on our sleep is crucial to minimizing potential health risks and ensuring a smooth adjustment to the time change.

What You'll Learn
Spring Forward means losing an hour of sleep
Spring Forward, also known as Daylight Saving Time, is when clocks are moved forward by one hour. This results in an extra hour of sunlight each day but also means losing one hour of sleep. While this may seem insignificant, losing an hour of sleep can have serious impacts on our health and well-being.
Our daily sleep-wake rhythm, or circadian rhythm, is closely tied to the 24-hour light-dark cycle. Spring Forward disrupts this rhythm, causing a mismatch between our internal clocks and our daily schedules. This can lead to sleep loss, sleep debt, and social "jet lag," affecting our ability to perform tasks and causing fatigue.
The effects of Spring Forward can be particularly challenging when adjusting to the new time. The week after the time change has been associated with a higher risk of traffic accidents, with a 6% increase in fatal car crashes. This is likely due to sleep deprivation, which can impair our alertness and reaction times.
In addition to the increased risk of accidents, Spring Forward can also negatively impact our health in other ways. Studies have shown a link between Spring Forward and an increased risk of cardiovascular events, including heart attacks and strokes. The disruption in sleep patterns can also worsen mental health conditions, intensifying mood disturbances, depression, and anxiety.
The loss of an hour of sleep can affect people of all ages, including children. Sleep-deprived children may experience difficulties in school and behavioural issues. However, older adults tend to be more tolerant of the effects of sleep deprivation. Overall, Spring Forward underscores the importance of sleep regularity and maintaining a consistent sleep schedule to minimize the impact of this annual time change.

This can disrupt your Circadian Rhythm
Daylight Saving Time (DST) is a centuries-old practice that occurs annually in March, when most people in the United States turn their clocks forward by one hour. While this change provides an extra hour of sunlight each day for the following eight months, it also results in one less hour of sleep for individuals.
This loss of sleep can have serious implications for health and well-being. One of the primary ways in which DST affects individuals is by disrupting their Circadian Rhythm, also known as their internal body clock. Circadian rhythms are 24-hour cycles that help regulate sleeping and eating patterns. They are closely tied to the light-dark cycle, with exposure to light playing a crucial role in maintaining these rhythms.
When DST begins, the shift in time results in less exposure to light in the morning and more exposure to light in the evening. This misalignment between your internal clock and your daily schedule can lead to sleep loss and social "jet lag." The effects of DST are particularly noticeable in individuals who already have inadequate sleep.
The disruption to Circadian Rhythm can have far-reaching consequences. Studies have shown an increase in fatal car accidents, especially among adolescent drivers, in the week following DST. This is likely due to the sleep deprivation and fatigue experienced by drivers. Additionally, DST has been linked to a higher risk of cardiovascular events, such as high blood pressure and heart disease and heart attacks. The negative impact on mental health is also significant, with an increase in symptoms of depression and anxiety, and even a rise in suicide rates.
The good news is that there are strategies to mitigate the effects of DST on your Circadian Rhythm. It is recommended to gradually adjust your sleep schedule by 10 to 20 minutes earlier each night a few days before DST begins. Maintaining a consistent sleep routine, even on weekends, can also help regulate your internal clock. Spending time in the morning sunlight can aid in resetting your Circadian Rhythm and making it easier to wake up earlier. Prioritizing sleep and practicing good sleep hygiene, such as avoiding screen time before bed, are crucial steps to take during this transition.

It can increase the risk of accidents
Losing an hour of sleep due to the spring forward transition can have serious implications for health and safety. Research shows a notable increase in fatal car accidents and workplace injuries in the days and weeks following the spring time change.
One study found a 6% increase in fatal traffic accidents during the workweek following the spring forward transition, resulting in approximately 28 additional deaths each year. The Canadian Centre for Occupational Health and Safety (CCOHS) also reported a 23% increase in car accidents on the Monday following DST, based on statistics averaged from 2005 to 2009. This loss of sleep can also lead to a higher incidence of accidents in the workplace, contributing to more emergency room visits and an increase in hospital admissions. A study in the Journal of Applied Psychology noted a 3.6% rise in workplace injuries on the Monday after DST, resulting in a 68% increase in lost workdays.
The time change can also intensify mood disturbances and worsen mental health conditions such as depression and anxiety. Sleep-deprived children may experience difficulties in school and even worsened behaviour. Additionally, the disruption to our natural sleep patterns can cause negative physical effects, including increased blood pressure and inflammation, which are both risk factors for heart attacks. A 2014 study published in Open Heart found a 24% increase in heart attacks on Mondays following the loss of an hour of sleep in the spring.
The spring forward transition can have far-reaching consequences, impacting our health, safety, and overall well-being. It is important to be aware of these risks and take steps to mitigate the negative effects, such as gradually adjusting sleep schedules, maintaining a consistent sleep routine, and prioritising rest.

It can have serious health impacts
Losing an hour of sleep due to the spring forward transition can have serious health impacts. Firstly, it can cause a disruption in our circadian rhythm or internal body clock, which helps regulate sleeping and eating patterns. This disruption can lead to sleep deprivation, resulting in fatigue and negatively impacting one's ability to perform tasks. Sleep-deprived children may experience difficulties in school and even worsened behaviour.
Secondly, the spring forward transition has been linked to an increased risk of accidents and errors. Research shows a significant increase in fatal traffic accidents, particularly involving adolescent drivers, just after the spring time transition. The Canadian Centre for Occupational Health and Safety (CCOHS) reported a 23% increase in car accidents on the Monday following DST, averaged from 2005 to 2009. Additionally, a 2009 study found a 3.6% increase in mining workplace injuries on the Monday after DST.
Thirdly, the loss of sleep can have serious cardiovascular implications. Studies have shown a significant increase in heart attacks in the days and weeks following the spring forward transition. There is also a higher risk of strokes, with one study revealing an eight per cent higher risk of ischemic stroke in the two days following the spring time change.
Lastly, the time change and sleep disruption can negatively impact mental health. It can intensify mood disturbances and worsen mental health conditions such as depression, anxiety, and even suicide rates, especially for those already vulnerable to such disorders.
While the spring forward transition provides an extra hour of sunlight and has some positive impacts on mental health, the loss of sleep can have significant and far-reaching consequences on overall health and well-being.

It can cause sleep debt and social jet lag
Daylight Saving Time (DST) is a centuries-old practice that occurs annually in March, when most Americans shift their clocks forward by one hour. While this change provides an extra hour of sunlight each day for the next eight months, it also results in an hour of sleep loss for many individuals. This disruption to sleep patterns can have significant negative consequences, including the development of sleep debt and social jet lag.
Sleep debt refers to the cumulative effect of not getting enough sleep. When individuals lose an hour of sleep due to DST, they may experience difficulty adjusting their sleep schedules, resulting in a ongoing state of fatigue and sleep deprivation. This can lead to impaired cognitive function, decreased productivity, and an increased risk of accidents and errors. Research has also linked sleep debt to various health issues, including cardiovascular problems such as high blood pressure and heart disease, weight gain, a weakened immune system, and an increased risk of depression and anxiety disorders.
The transition to DST not only affects individuals' sleep schedules but also their social and occupational routines. The shift in sunrise and sunset times can create a mismatch between internal body clocks and daily demands, resulting in what is known as social jet lag. This phenomenon occurs when individuals struggle to align their sleep-wake cycles with the altered light-dark cycle, leading to a disruption in their circadian rhythm or internal body clock. Social jet lag can exacerbate the negative consequences of sleep debt, making it challenging for individuals to perform their daily tasks and meet social and work obligations.
The effects of DST on sleep debt and social jet lag can be particularly pronounced in certain populations. For example, children may experience difficulties in school and behavioural issues due to sleep deprivation. Pregnant women, especially those who conceived through IVF, may face increased health risks, as a 2017 study found an association between DST and an increase in miscarriages for patients who received egg transfers during the DST window. Additionally, individuals with pre-existing mental health conditions, such as depression and anxiety, may experience a worsening of their symptoms due to the disruption in their sleep patterns.
To mitigate the impact of DST on sleep debt and social jet lag, experts recommend gradually adjusting sleep schedules before the time change. This involves going to bed and waking up earlier in small increments, such as 10 to 15 minutes or 15 to 20 minutes, a few days before DST begins. Maintaining a consistent sleep routine, getting early morning sunshine, and practising good sleep hygiene, such as avoiding screen time before bed, can also help minimise the negative consequences of the time change.

Frequently asked questions
No, spring forward means less sleep. Every spring, most Americans turn their clocks forward by one hour during daylight saving time (DST). This results in a loss of roughly 40 minutes to an hour of sleep.
Losing an hour of sleep can negatively impact our health. Sleep deprivation can lead to fatigue, increased risk of cardiovascular events such as high blood pressure and heart disease, weight gain, a weakened immune system, and worsened mental health conditions such as depression and anxiety. It can also cause a disruption in our circadian rhythm or internal body clock, leading to sleep deprivation and social "jet lag".
To minimize the impact of spring forward on your sleep, you can gradually adjust your sleep schedule by 10 to 20 minutes earlier each night a few days before the switch. Maintaining a consistent sleep routine and getting early morning sunshine can also help regulate your internal clock. Taking short naps during the day can help lessen sleep debt, but they should not be longer than 20 minutes to avoid feeling groggy.
