People assume seasonal depression belongs to places with long dark winters, and conclude it cannot be what is happening to them in Houston. That assumption misses two things. Daylight here still drops meaningfully in December, and Houston has a second seasonal pattern that colder cities do not: the summer, when heat and humidity keep people indoors for months in a way that functions much like a northern winter.
The Winter Version
Shorter days, less light exposure, and a disrupted circadian rhythm produce low mood, heavy fatigue, oversleeping, carbohydrate cravings, weight gain, and social withdrawal, arriving around the same months each year and lifting in spring. It is milder here than in Minneapolis. Milder is not the same as absent.
The Houston Summer Version
From roughly June through September, life indoors becomes the default. Exercise stops, outdoor plans stop, sunlight exposure paradoxically drops because nobody wants to be in it, and social contact narrows. The presentation tends to run the other way from winter: agitation and irritability rather than heaviness, insomnia rather than oversleeping, and appetite loss rather than craving.
If your mood reliably deteriorates in July, you are not imagining it and it is not a personal failing about the heat.
What to Watch For
- A pattern that repeats at the same time of year for at least two consecutive years
- Mood, energy, and sleep changes that track the calendar rather than events
- Withdrawal from people and activities during a specific season
- Drinking that increases predictably in the same months
- Full recovery outside that window, which is what distinguishes it from ongoing depression
What Helps
Light exposure, whether outdoors in the morning or with a light box, has evidence for the winter pattern. So do maintaining activity and social contact deliberately rather than by inclination, protecting a consistent sleep schedule, and, for the summer pattern in Houston, finding ways to stay active that do not require being outside at two in the afternoon. Talk to a prescriber before adding light therapy if you have bipolar disorder, since it can affect mood cycling. See our bipolar article.
A pattern you have noticed for years?
Worth an assessment rather than another season of waiting it out.
When It Is More Than Seasonal
Seasonal changes should lift. If the low mood does not fully resolve outside the season, if it is deepening year over year, or if there are thoughts of self-harm, that is depression that needs treatment on its own terms rather than a seasonal explanation. Call or text 988 if you are having thoughts of harming yourself. Our depression treatment article covers the broader picture.
The Drinking Overlap
Alcohol use often rises in the same window, whether from indoor social patterns or from managing low mood, and it deepens the depression it is being used to treat. If both move together on your calendar, treating them together is the approach that holds. See depression and alcohol and dual diagnosis.
If this is an emergency or you are thinking about harming yourself, call 911, or call or text 988 to reach the Suicide and Crisis Lifeline. In Harris County, The Harris Center operates a 24-hour crisis line at 713-970-7000. Heights Behavioral Health is an outpatient program and is not a 24-hour crisis service.
Frequently Asked Questions
Can you get seasonal depression in Houston?
Yes. Winter daylight still drops meaningfully here, and Houston has a distinct summer pattern where heat keeps people indoors for months, which produces a similar effect.
How is summer seasonal depression different?
It tends to bring agitation, insomnia, and appetite loss rather than the heaviness, oversleeping, and carbohydrate cravings more typical of the winter pattern.
Do you take insurance?
We are private pay and out of network, and not in network with any plan. Whether you need a short course or ongoing care, the cost is explained before you commit. Some clients use out-of-network benefits to offset part of it, and we provide the superbill.
How do I know if it is seasonal or ongoing depression?
The distinguishing feature is full recovery outside the season, repeating over at least two consecutive years. If mood never fully lifts, it needs assessment as depression rather than a seasonal pattern.
Does light therapy work?
It has evidence for the winter pattern. Speak with a prescriber first if you have bipolar disorder, as light therapy can affect mood cycling.
When should I get treatment?
If the pattern repeats yearly, disrupts work or relationships, drives increased drinking, or does not lift as expected. Recognizing it before the season arrives makes it far easier to manage.
