Winter, Mood, and Recovery

As the days grow shorter and darker across Ohio each fall and winter, many people notice more than a dip in the weather — they feel a dip in their mood, energy, and sleep. For some, that's seasonal affective disorder (SAD), a recurring form of depression tied to the seasons that affects an estimated 10 million Americans. SAD matters far beyond mood: it frequently overlaps with substance use, and that connection has real implications for anyone managing chronic pain or in recovery. This article adapts research by the RegenLife / Pain Specialists of Cincinnati team — Majors Badgett, PhD, Dr. Zeeshan Tayeb, MD, and Daryl Flotka — into plain language for patients.

Key Takeaways

• Seasonal affective disorder (SAD) is a seasonal form of depression affecting roughly 10 million Americans, with symptoms that usually begin in fall and continue through winter.
• SAD and substance use disorders (SUD) are highly linked — about half of people with a substance use disorder also experience a mental health condition, and vice versa.
• People living farther north are more affected: SAD prevalence runs about 9.7% in New Hampshire versus 1.4% in Florida — putting Ohio's shorter winter days squarely in the higher-risk range.
• For people managing chronic pain, seasonal mood changes deserve proactive, compassionate monitoring — not judgment.
• Effective, well-established treatments exist: light therapy, vitamin D, counseling, and antidepressants.

What Is Seasonal Affective Disorder?

SAD is a type of recurrent depression that follows a seasonal pattern. For most people affected, symptoms start in the fall and persist through the winter months — including low mood, lethargy, poor sleep, irritability, and depression.

The biology is tied to light. As daylight shrinks, the body tends to produce more melatonin (the hormone that regulates sleep), less serotonin (a neurotransmitter that helps balance mood), and gets less vitamin D. Together, these shifts can disrupt your circadian rhythm — the internal clock that governs how your body responds to the light-dark cycle over 24 hours. Because sunlight drives so much of this, SAD becomes more common the farther you live from the equator, which is why residents of northern states like Ohio are more susceptible than those in sunnier climates.

The Link Between Mood and Substance Use

Here's the connection that makes SAD especially important in a pain and recovery setting: mental health conditions and substance use disorders very often occur together. Around half of people with a substance use disorder will also experience a mental health disorder, and more than 20% of people with a past-year substance use disorder also had a mood disorder such as SAD.

One reason is self-medication — using substances to blunt the low mood, fatigue, or sleeplessness that SAD brings. The numbers are striking: compared with people without a mental illness, people with a mental illness have been found to use alcohol about 20% more, cocaine about 27% more, and cigarettes about 86% more. In one alcohol and substance abuse program, 23% of patients had SAD. And the Mayo Clinic has reported a link between low vitamin D levels and higher use of narcotic pain medication — a reminder of how tightly mood, biology, and pain are intertwined.

For patients who are prescribed opioids, this matters even more, because access to medication is already close at hand. None of this is about blame — it's about recognizing a real, seasonal vulnerability so we can support patients before a difficult season becomes a crisis.

How We Monitor and Support Patients Through the Darker Months

Because SAD peaks in fall and winter, that's exactly when closer support pays off. Two practical, evidence-based tools help:

• Thoughtful urine drug testing (UDT). Rather than a "gotcha," seasonal toxicology monitoring is a safety and support tool. Increasing routine testing during the higher-risk months lets the care team check in on how patients are really doing — while they're going about their normal routine — and step in early with help when it's needed.
• Seasonal screening (SPARQ). The Seasonal Pattern Assessment Questionnaire is a free, self-administered screen that asks how your energy, sleep, weight, mood, and appetite change with the seasons — a simple way to flag SAD so it can be treated.

From there, SAD itself is very treatable. Well-established options include light therapy, a vitamin D regimen, counseling, and antidepressants — often combined with the kind of whole-person support offered through behavioral health and lifestyle medicine.

An Honest Note on the Data

It's worth being precise: national statistics do not show that overdoses or substance use consistently spike in specific months — in part because reliable month-by-month data is limited, and overall trends have been rising year over year, which makes seasonal patterns hard to isolate. What the evidence does support is that SAD is seasonal and strongly comorbid with substance use — which is why seasonal awareness and monitoring for patients prescribed opioids is a prudent, patient-centered practice. More research on month-level data, especially for patients on prescription opioids, is still needed.
