How to prepare your body and mind for the end of daylight saving time

Daylight saving time is coming to this years end in the U.S., which occurs at 2 a.m. local time on November 3, 2024. As clocks are set back one hour, people gain an extra hour of sleep. However, this change can disrupt sleep patterns, as darker evenings may affect individuals' internal body clocks, making it harder to adjust to the new schedule.

There are potential health impacts associated with the time change, including an increase in heart attacks and strokes during the "spring forward" transition. Some people may also experience seasonal affective disorder due to decreased sunlight in the "fall back" timeframe (now) during fall and winter. Experts recommend gradually adjusting sleep schedules before the time change and getting exposure to natural light to help reset circadian rhythms.

There is ongoing debate about eliminating the practice of changing clocks altogether, with some proposing to make daylight saving time permanent. Health authorities suggest that sticking with standard time may better align human biology with sunlight patterns.

US Regions Not Using Daylights Savings Time

In the United States, there are a few states and regions that do not observe Daylight Saving Time (DST).

States That Do Not Observe DST

1. Arizona:

Most of Arizona does not observe DST due to the state's extreme heat. By not shifting the clock forward in spring, the state avoids having more daylight during the hotter months, which can help reduce energy consumption used for cooling.

2. Hawaii:

Hawaii does not observe DST because of its tropical climate. The amount of daylight does not vary significantly throughout the year, and there is little need for adjusting clocks to make better use of daylight.

U.S. Territories

Several U.S. territories also do not observe DST:

1. Puerto Rico
2. Virgin Islands
3. American Samoa
4. Guam
5. Northern Mariana Islands

General Reasons for Not Observing DST

Climate Considerations

In areas like Arizona and Hawaii, the climate plays a significant role. Longer daylight in the evening during hot months can lead to increased energy consumption for cooling.

Geographical Factors

Regions closer to the equator experience less variation in daylight hours throughout the year, making DST less beneficial.

Cultural Preferences

Some regions may prefer a consistent time throughout the year for social, religious, or economic reasons.

These states and territories have chosen to opt-out of Daylight-Saving Time for practical reasons that align with their geographic and climatic conditions.

Pros and Cons of not using Daylight Saving Time (DST):

Pros

• Consistency: Eliminating DST leads to a consistent time throughout the year, which can simplify scheduling for businesses and individuals.
• Health Benefits: It may reduce health issues related to the disruption of sleep patterns caused by the time change, such as increased risk of heart attacks, strokes, and mental health problems.
• Reduced Accidents: Studies suggest fewer traffic accidents occur when there is no time change, as people are less likely to be sleep-deprived.
• Simplified Time Management: It removes the need to adjust clocks twice a year, which can cause people to clock the wrong time, making them late for engagements or be off until it is realized.

Cons

• Less Evening Daylight: Not using DST means shorter daylight hours in the evening during the summer.
• Adjustment Periods: People may need to adjust their schedules to accommodate the lack of extended daylight, which could lead to temporary disruptions.
• Potential for Increased Energy Use: Some studies suggest that not having DST could lead to increased energy consumption in the evening due to reliance on artificial lighting.
• Negative Impact on Agriculture: Farmers and agricultural workers often rely on daylight hours for their work, and changes in daylight can impact their productivity and efficiency.

The decision to keep or eliminate Daylight Saving Time involves weighing these pros and cons based on local needs and preferences.

Being Prepared

Preparing for the changes between Daylight Saving Time (DST) and Standard Time (ST) involves several steps to help you adjust smoothly. Here are some tips:

1. Adjust Your Schedule Gradually

Shift Sleep Times: A few days before the change, start going to bed and waking up 15-30 minutes earlier or later, depending on whether you're moving to ST or DST.

Meal Times: Adjust your mealtimes similarly to help your body adapt.

2. Utilize Light Exposure

Morning Light: Get plenty of natural light in the morning after the time change, which can help reset your internal clock.

Limit Evening Light: Reduce exposure to bright screens in the evening as you approach the time change.

3. Maintain Consistent Sleep Hygiene

Set a Sleep Routine: Keep a consistent sleep schedule, even on weekends.

Create a Relaxing Environment: Ensure your bedroom is conducive to sleep—cool, dark, and quiet.

4. Stay Active

Exercise Regularly: Physical activity can help you feel more awake during the day and sleep better at night, therefore naturally helping your body regulate to the time difference.

5. Be Mindful of Mood and Energy Levels

Monitor Changes: Be aware of how the time change affects your mood and energy. If you're feeling unusually tired or irritable, give yourself time to adjust.

Mental Health: If you notice disruptions in your normal demeanor, pay extra care to your mental health. Doing things that make you happy and remember to breathe through the tough points.

6. Plan for Transition

Schedule Important Tasks Wisely: Avoid scheduling important meetings or activities immediately after the time change, as you may be less alert or prepared.

7. Stay Informed

Know the Dates: Familiarize yourself with when DST starts and ends in your region to prepare accordingly.

Know Your Clocks: Know which clocks require manual set back/forward and which ones automatically get reset with the satellites.

By following these steps, you can make the transition between Daylight Saving Time and Standard Time smoother and minimize disruptions to your daily routine.
