Daylight Saving Time and Mental Health in Michigan: Which Time Is Better?

How Daylight Saving Time and Mental Health Are Connected

Daylight saving time and mental health are closely connected, especially when Michigan residents must suddenly adjust their sleep, morning routines, and exposure to daylight.

Twice each year, Michigan residents reset their clocks—and often spend the next several days resetting their sleep. Congress is now considering whether to end these time changes and keep daylight saving time year-round.

Ending the clock changes may sound simple. However, the decision involves another important question: Should Michigan remain on permanent daylight saving time or permanent standard time?

The difference could affect sleep, mood and daily life, especially during Michigan’s dark winter months.

What Is Congress Proposing?

On July 14, 2026, the U.S. House of Representatives passed the Sunshine Protection Act. The Senate received the bill on July 15 and referred it to the Committee on Commerce, Science, and Transportation. It must still pass the Senate and be signed by the president before becoming law.

The proposal would end the twice-yearly clock changes and make daylight saving time permanent in most states.

Permanent daylight saving time would not create more sunlight. It would simply shift an hour of daylight from the morning to the evening according to the clock. For Michigan families, that could mean more evening light after work—but darker winter mornings.

How Does the Time Change Affect Mental Health?

Sleep and mental health are closely connected. Losing sleep can make it harder to concentrate, manage emotions, and cope with stress. People may feel more irritable, anxious, tired, or discouraged after their sleep schedules change.

The spring change is usually harder because people lose an hour and must begin sleeping and waking earlier. Many people feel better within several days, but children, teenagers, shift workers and people with existing sleep or mental health concerns may take longer to adjust.

Consider a parent who normally wakes at 6:30 a.m. After the spring change, the clock says 6:30, but the parent’s body may still feel as though it is 5:30. The children are difficult to wake, everyone is rushed, and the parent begins the workday already tired and frustrated.

The fall change does not usually cause the same sleep loss. However, suddenly losing an hour of evening light may affect mood and daily habits.

A large Danish study of more than 185,000 hospital contacts for depression found an 11% increase in unipolar depressive episodes after the fall return to standard time. The increase gradually disappeared over approximately 10 weeks.

This does not mean everyone needs 10 weeks to reset their body clock. A person may adjust their sleep within a few days while still being affected by darker evenings, less outdoor activity, and the beginning of the winter season.

For instance, a Michigan office worker may stop waking unusually early within a week. However, leaving work in darkness may cause her to stop taking evening walks. Over time, less daylight, movement and social activity may contribute to worsening mood.

Would Permanent Daylight Saving Time Be Better?

Permanent daylight saving time would provide more evening light. Michigan residents might have more opportunities to walk, complete outdoor projects, attend children’s activities or spend time outside after work.

That could be valuable for someone who struggles when darkness arrives before the workday ends.

However, permanent daylight saving time would also delay winter sunrise by one clock-hour. Many Michigan children would travel to school in darkness, and adults could begin work before receiving meaningful morning light.

Imagine a teenager who must wake at 6:15 a.m. for school. Under permanent daylight saving time, winter mornings would remain dark later. The teenager would receive less morning light, which helps signal the brain that it is time to wake. Additional evening light could also make it harder to feel sleepy at bedtime.

Why Sleep Experts Prefer Standard Time

The American Academy of Sleep Medicine supports ending seasonal clock changes but recommends permanent standard time rather than permanent daylight saving time.

Standard time more closely follows the natural cycle of sunlight. Morning light helps set the body’s internal clock, increase alertness, and support an earlier sleep schedule. Light later in the evening can delay melatonin production and make the body feel that bedtime should occur later.

This may be especially important for people experiencing depression, anxiety, insomnia or seasonal mood problems.

A common situation is an adult with depression who already struggles to get moving on dark Michigan winter mornings. If sunrise occurs an hour later, that person may drive to work and begin the day without receiving the morning-light signal that helps regulate sleep and alertness.

Shift workers may face a different challenge. A healthcare worker who finishes an overnight shift may already have difficulty maintaining a regular sleep schedule. Moving daylight later into the evening may create additional light exposure when that person is trying to prepare for sleep.

The key difference: Permanent daylight saving time does not create more sunlight. It moves one hour of daylight from the morning to the evening. Permanent standard time keeps more light in the morning, which better matches the body’s natural sleep-wake rhythm.

Which Choice Is Better for Michigan?

There is no perfect clock system for every person. Permanent daylight saving time offers more usable evening light. Permanent standard time provides more morning light and is better aligned with the body’s circadian rhythm.

From a sleep and health standpoint, major medical and sleep organizations favor permanent standard time. From a lifestyle standpoint, many families prefer daylight saving time because they value brighter evenings.

The clearest point of agreement is that changing the clocks twice each year can disrupt routines, sleep and mood. Ending those changes may help—but Michigan residents should understand that the current federal proposal favors permanent daylight saving time, not the permanent standard time recommended by sleep experts.

Regardless of what Congress decides, consistent sleep times, morning outdoor light, regular movement and attention to persistent mood changes can help Michigan residents protect their mental health throughout the darker months. When changes in sleep or mood begin affecting daily life, individual counseling in Michigan may provide additional support.
