Learn about the start of daylight savings time, when we set our clocks forward in the spring. Plus, 9 tips on how to adjust to daylight savings time.

When the clocks change each year, many of us find it hard to adjust to the shift in our daily routines. The transition to daylight savings time, while offering longer daylight hours, can disrupt our internal clocks and leave us feeling out of sync. This change, while seemingly small, can noticeably impact our overall wellbeing until we’re able to re-synch our internal body clocks.

 

What and when is daylight saving time?

Daylight saving time, (colloquially known as daylight savings, or daylight savings time,) is a system we use to make better use of natural daylight. By setting our clocks forward by one hour during the warmer months, we can enjoy longer evenings. This change usually happens in the spring and can be remembered with the term "spring forward." When the cooler months roll in around autumn, we set our clocks back, or “fall back”, by an hour to standard time.

The practice of daylight savings was originally introduced to conserve energy. The idea was that by having more daylight in the evenings, people would use less artificial lighting and electricity. While its effectiveness in energy saving is debated, daylight savings time is still normal in many parts of the world.

So, when exactly does this change happen? Typically, daylight savings time begins on the second Sunday in March and ends on the first Sunday in November. This means that in the spring, we set our clocks forward during the night, effectively losing one hour of that day. In the fall, we do the opposite, which gives us one extra hour that day.

 

How does a change in daylight savings time affect our health?

Daylight savings time impacts our circadian rhythm—the internal clock that helps regulate our sleep-wake cycle, appetite, energy levels, and mood. With daylight savings time, our internal clock experiences a sort of mini jet lag, leading to adjustments in our routines.

This change can disrupt our sleep patterns, making it harder to fall asleep at our usual time and potentially causing us to feel groggy in the morning. Similarly, when we "fall back" and gain an hour, it can also take a bit of time for our bodies to adapt.

These shifts in time don't have specific or severe health effects for most people. However, they can temporarily affect how we feel. For example, some of us might be more tired than usual, have slight changes in our appetite, or even feel emotionally out of sorts. These are normal responses as our bodies work to align with the new time.

Fortunately, our bodies are adaptable—although it can take up to a week to adjust to the new time. During this period, be patient with yourself and understand that a little disruption is normal

Maintaining healthy habits can significantly aid the adjustment process. Adapting to daylight savings time is an opportunity to be mindful of your body’s needs and support your overall wellbeing.

 

9 tips to adjust to when the clocks change

Adapting to daylight savings time can be made smoother with some simple, effective strategies. Small adjustments can significantly affect how you feel and function during this time change.

1. Shift your schedule gradually

In the days leading up to the time change, adjust your sleep and wake times by 15 minutes each day. This gradual shift can ease the transition for your body's internal clock.

2. Ensure quality sleep

Aim for a good night's sleep, especially in the days before there’s a time change—a well-rested body can find it easier to adapt. Create a restful sleep environment and enhance your sleep hygiene by dimming lights, reducing noise, and creating a relaxing bedtime routine.

3. Practice meditation and mindfulness

Engage in meditation or mindfulness exercises to help soothe your mind and body, making adjusting to the new time easier.

4. Adjust your clocks before bedtime

On the night of the time change, set your clocks to the new time before you go to sleep. This can help your mind accept the new time as you start the next day.

5. Get plenty of daylight

Spend time outside in natural light, especially in the morning. Daylight helps reset your internal clock and improve your mood and alertness.
