Not everyone with depression has the same symptoms or experiences them with the same intensity. Some people may have symptoms only during certain times of the year.

If you tend to experience depression around the same months every year, a mental health professional may diagnose your symptoms as MDD with a seasonal pattern.

This article will discuss what some people call summer depression, its common symptoms and causes, and how to manage it.

Summer depression is not a formal or accurate clinical term. Still, some people may use it to refer to symptoms of depression experienced mostly during warmer months of the year.

These symptoms may be better explained by a formal mental health condition known as major depressive disorder with a seasonal pattern.

Formerly called seasonal affective disorder (SAD), this condition is a subtype of clinical depression. It refers to depression symptoms that recurrently develop and resolve with seasonal changes.

Seasonal depression is more common during fall and winter. In fact, some people call it the winter blues.

In some cases, though, symptoms occur during summer. That is why some experts refer to summertime depression as reverse seasonal affective disorder.

MDD is a manageable condition. A mental health professional may help you explore structured treatment plans that fit your needs and symptoms. Relief is possible.

What are the symptoms of seasonal depression in the summer?

To diagnose MDD, a mental health professional may want to explore your medical history and current symptoms.

According to the Diagnostic and Statistical Manual of Mental Disorders, 5th edition, text revision (DSM-5-TR), a diagnosis of MDD requires that you have experienced at least five of these nine symptoms in the past 2 weeks or longer:

  • low mood (sadness, hopelessness, emptiness) most of the day for most days
  • difficulty experiencing pleasure or joy during usual activities
  • changes in weight or appetite
  • changes in sleeping patterns that could mean sleeping fewer or more hours than usual
  • changes in the way you move, like moving slower or being more agitated than usual
  • fatigue and low motivation
  • feelings of worthlessness or guilt
  • persistent thoughts of death, including suicide attempts

Seasonal depression in summer may specifically involve:

  • insomnia
  • irritability and anxiety
  • episodes of violent behavior
  • poor appetite

To identify a summer seasonal pattern, your mental health professional will want to know if you have experienced your symptoms for at least 2 summers before the current one. They will also want to know whether your symptoms improved once the season ended — in other words, if you have experienced depression symptoms only during the summer months.

Your mental health professional will also explore how these symptoms interfere with regular activities, like social interactions, school, or work.

They may ask you about events that tend to repeat during this time of the year, such as if you become unemployed every summer or if a loved one moves away during this time every year. These psychosocial challenges may better explain some of your symptoms, which may lead your doctor to move away from a seasonal pattern diagnosis.

Is it depression or sadness?

It is natural to wonder whether your symptoms relate to sadness or add up to a clinical diagnosis. Typically, these three factors may help you tell the difference between sadness and depression:

  1. Duration: Depression symptoms occur most of the day, every day, for at least 2 weeks. Sadness may come and go or depend on what you are doing at the time.
  2. Severity: Sadness refers to low mood, which may affect your energy and motivation levels. You may still enjoy company or your usual activities. Depression, on the other hand, involves at least five of the mentioned nine symptoms and goes beyond low mood. You may have difficulty feeling pleasure even when doing things you used to enjoy.
  3. Impairment: You may be able to function at school or work when you are sad. Depression usually interferes to some degree with your ability to socialize, focus, recall information, and do creative tasks. You may tend to forget things, have trouble understanding what you read or what others say, and prefer to isolate yourself from other people.

Only a mental health professional can offer you an accurate diagnosis and recommend management strategies.

What causes seasonal depression?

The cause of depression has not been established yet. Mental health experts suspect it is a combination of two or more of these factors:

  • genes
  • environmental and psychosocial influences
  • adverse life experiences
  • biochemical changes in the brain

In the case of summer depression, these factors may also be involved:

  • increased humidity and heat that affect energy levels
  • longer hours of sunlight that influence your natural body clock, which regulates important functions, including your mood
  • changes in routine during summer
  • activities that may affect body and self-image

It is also possible that melatonin production is at the core of seasonal depression during summer.

Melatonin is a hormone produced by your pineal gland in response to darkness. It signals that it is time to rest and sleep. Fewer night hours may decrease melatonin production, making it harder for you to relax and sleep. Fewer sleep hours may affect your mood.

How is major depressive disorder treated?

Clinical depression is a treatable condition, and relief is possible. If you are experiencing symptoms of depression, consider discussing them with a health professional.

Depression treatment depends on your individual situation. Helpful strategies may include the following:

  • Talk therapy: Cognitive behavioral therapy is often recommended to manage depression.
  • Medications: In some cases, antidepressant duloxetine (Cymbalta), escitalopram (Lexapro), sertraline (Zoloft), and bupropion (Wellbutrin) may help you manage severe symptoms.
  • Self-care: Social support, grounding techniques, and mindfulness practice may complement medical treatment.
  • Physical activity: Moving more may help your body regulate hormone production, which in turn may have an effect on your mood. Walking, dancing, swimming, or even doing more chores may help your body get the movement it needs.

Working with a compassionate mental health professional may help you develop a plan you feel comfortable with.

Summary

Summer depression is not a formal medical term but may refer to a mental health condition called MDD with a seasonal pattern. It was formerly known as SAD.

Most people with the condition experience symptoms during the colder months of the year, but it is also possible to have them during summer.

To reach a seasonal depression diagnosis, a mental health professional will explore whether you have had symptoms for at least 2 summers before and whether those symptoms lasted for 2 weeks or longer every time.

Symptoms of summer depression may include lack of appetite, irritability, sadness, difficulty sleeping, and restlessness.

Depression is a treatable condition. Reaching out to a mental health professional can help you explore management options.
