Atlanta, GA – November 1, 2025 – As the clocks turned back on november 2nd, signaling the end of Daylight Saving Time, health professionals are issuing warnings about the potential impact of shorter days on both physical and mental well-being. A recent report highlighted the increased risks of sleep disturbances and seasonal affective disorder (SAD) as the southeastern region, including Georgia, experiences decreasing daylight hours.
The Impact of Diminishing Sunlight
The shift to standard time, granting an extra hour of sleep, is often welcomed, however, a reduction in sunlight exposure can significantly disrupt biological rhythms. Dr. Victoria Park, a leading sleep medicine researcher at emory University, explains that sunlight is a crucial regulator of hormonal balance, specifically melatonin and serotonin – hormones that influence sleep and mood.
“When light levels decrease, this delicate balance is thrown off, perhaps leading to sleep problems and mood changes,” Dr. Park stated. “Prioritizing sunlight exposure, maintaining a consistent sleep schedule, and seeking professional support when needed are essential steps for navigating the winter months.”
Adjusting to the Time Change and Prioritizing Sleep
Experts estimate it takes approximately five days for the body to fully adjust to the return to standard time. During this adjustment period, disrupted sleep patterns can negatively affect concentration, emotional regulation, and overall mood. The Centers for Disease Control and Prevention (CDC) recommends adults aim for at least seven hours of sleep nightly, citing links between insufficient sleep and increased risks of hypertension, obesity, and type 2 diabetes.
Cultivating Healthy Sleep Habits
Dr. Robin Courtney, a psychiatrist at Piedmont macon Hospital, emphasizes the importance of adopting “sleep hygiene” practices.These include minimizing exposure to bright screens-such as televisions and mobile phones-at least one hour before bedtime. Maintaining a regular sleep-wake cycle, ensuring a quiet and cozy sleep environment, and avoiding caffeine, alcohol, and late-night meals are also critical components of good sleep hygiene.
Did You No? Taking a hot shower promptly before bed can actually interfere with sleep. The body’s natural temperature drop signals drowsiness, but hot water can delay this process.
Vitamin D Deficiency and Winter Insomnia
Experts identify vitamin D deficiency as a common contributor to sleep disorders during the winter months. Dr. Rami Apoush, a sleep specialist at Piedmont Hospital, notes that many individuals are deficient in vitamin D, particularly when sunlight exposure is limited. Supplementation might potentially be beneficial, but it’s crucial to consult with a healthcare professional regarding appropriate dosage, as supplements are not consistently regulated by the Food and Drug administration.
Combating Seasonal Depression
The “winter blues,” characterized by depression and lethargy, are often exacerbated by the lack of sunlight. Sunlight stimulates serotonin production in the brain,a neurotransmitter strongly associated with feelings of happiness and well-being. The cycle of reduced sunlight, diminished vitamin D levels, decreased serotonin, and subsequent depression can be challenging to break.
“Light therapy,” using a ‘light box’ that emits bright artificial light-approximately 20 times the intensity of natural light-can be a helpful tool for managing SAD and sleep disturbances. This technique helps regulate the body’s biological clock and hormonal activity and has been a standard treatment for SAD since the 1980s, with 20-30 minutes of morning exposure proving effective.
Recognizing the Symptoms of Seasonal Depression
Symptoms of seasonal depression may include social withdrawal, diminished interest in activities, excessive sleepiness or insomnia, persistent fatigue, feelings of hopelessness, changes in appetite, and difficulty concentrating. Experts urge individuals experiencing these symptoms for more than two weeks to seek professional assistance.
| symptom | Possible Cause | Recommended Action |
|---|---|---|
| Sleep Disturbances | Disrupted Circadian Rhythm | Maintain a Consistent Sleep Schedule |
| Low Mood | Reduced Serotonin Levels | Consider Light Therapy, Seek Counseling |
| Fatigue | vitamin D Deficiency | Vitamin D Supplementation (with doctor’s approval) |
Staying Healthy Through the Winter: Long-Term Strategies
Beyond addressing immediate symptoms, adopting proactive strategies throughout the winter months can bolster overall well-being. Regular physical activity, a balanced diet rich in essential nutrients, and social engagement all contribute to better physical and mental health. Prioritizing self-care and finding healthy ways to cope with stress are crucial during this time of year.
