Yes, Summertime Sadness Is Real: Understanding Summer-Onset Seasonal Affective Disorder

When people think about Seasonal Affective Disorder (SAD), they usually imagine long, gray winter days, cold weather, and a lack of sunlight. But for some, the change in seasons triggers something very different. Instead of the winter blues, they experience deep sadness, anxiety, or irritability during the summer months. This condition is known as summer-onset Seasonal Affective Disorder, and it is very real.

What Is Summer SAD?

Summer-onset SAD is a type of depression that follows a seasonal pattern. While it is less common than winter SAD, it affects many people each year. Symptoms typically begin in late spring or early summer and improve when the weather cools down in the fall.

Unlike winter SAD, which is often linked to too little sunlight, summer SAD may be caused by too much sunlight, heat, and disrupted routines. Long days, social pressure to feel cheerful, and overstimulation can all play a role in triggering symptoms.

Common Symptoms of Summer SAD

Symptoms of summer-onset SAD may include:

  • Trouble sleeping (insomnia)

  • Anxiety or restlessness

  • Loss of appetite or weight loss

  • Feelings of sadness or hopelessness

  • Difficulty concentrating

  • Increased irritability or agitation

  • Withdrawal from social situations

Some people also feel overwhelmed by summer’s sensory stimulation, such as loud events, bright light, and crowded spaces. The pressure to “enjoy the season” can make things worse.

What Causes Summer SAD?

There is no single cause, but research suggests several contributing factors:

  • Longer daylight hours can disrupt circadian rhythms and sleep patterns.

  • Heat and humidity may cause physical discomfort and increase irritability.

  • Social expectations like vacations, body image pressures, and constant activity can be emotionally draining.

  • Changes in routine due to school breaks or altered work schedules can lead to feelings of instability or isolation.

Summer SAD may also be linked to existing mood or anxiety disorders, hormone fluctuations, or trauma anniversaries that occur during this season.
