Most people associate seasonal affective disorder (SAD) with the cold, gray days of winter. Often called the “winter blues,” winter-onset SAD affects many as shorter days and less sunlight disrupt mood and energy. But there’s another side to this type of depression that often goes unnoticed—summer-onset SAD.
Though less common, seasonal transitions into the summer months can also affect mental health, triggering symptoms like social withdrawal, insomnia, and mood shifts. If you’ve ever felt “off” just as everyone else seems to be enjoying sunny days and vacations, you’re not alone.
Let’s explore what summer SAD looks like, how the impact of seasonal change influences sleep patterns, mood, and energy levels, and what you can do to find balance.
What Is Summer-Onset SAD?
Seasonal affective disorder (SAD) is a recurring form of depression linked to the changing seasons. While most people are familiar with the winter onset form, summer-onset SAD usually begins in late spring or early summer and may ease as fall approaches.
Symptoms of summer SAD often include:
- Difficulty sleeping or changes in circadian rhythm
- Restlessness or agitation
- Weight loss due to decreased appetite
- Social withdrawal, even when social opportunities increase
- Feelings of hopelessness or irritability
- Fatigue or decreased energy levels
These symptoms can disrupt relationships, work, and day-to-day life—especially when they seem out of sync with the upbeat tone of summer.
What Causes Summer SAD?
The exact cause of summer SAD isn’t fully understood, but several factors may contribute:
- Serotonin levels: Sunlight impacts serotonin, a brain chemical that affects mood. In some individuals, excess heat or extended daylight may actually disrupt serotonin balance.
- Changes in routine: Longer days can mean later bedtimes, more social commitments, and disrupted sleep patterns. This can throw off your circadian rhythm and leave you feeling drained.
- Body image or social pressure: The season often brings increased exposure to social situations, vacations, or heightened use of social media which can intensify self-criticism or feelings of being left out.
- Heat sensitivity: Some individuals simply don’t tolerate heat well. High temperatures can interfere with sleep and overall comfort, contributing to mood changes.
Summer SAD vs. Winter SAD
While both forms of SAD are influenced by the impact of seasonal change, the symptoms differ:
- Winter SAD often involves weight gain, oversleeping, and a craving for carbs.
- Summer SAD usually leads to weight loss, insomnia, and reduced appetite.
Recognizing the difference is key to seeking the right kind of help.
How to Cope and When to Seek Help
Coping with seasonal affective disorder (SAD) starts with awareness. Here are some strategies that may help:
- Create consistent routines: Sticking to regular sleep and meal schedules can help regulate your circadian rhythm and stabilize mood.
- Practice cooling self-care: Stay physically comfortable with cool showers, light clothing, and hydration.
- Limit social overload: It’s okay to say no to invitations. Balance rest with activity.
- Seek darkness at night: Use blackout curtains or sleep masks to counter longer daylight hours and support healthy sleep patterns.
- Try light therapy cautiously: While it’s commonly used for winter-onset SAD, talk to a mental health professional before trying it in summer—it may not be helpful (or could make symptoms worse).
