Seasonal Depression: Early Signs and How to Prepare for Fall

With the end of September comes cooler temperatures, earlier sunsets, and less daylight.

For individuals, these changes might slowly influence energy, sleep, motivation and mood. Just feeling sad or tired sometimes doesn’t guarantee you have seasonal depression, but noticing a trend can help you get help before symptoms become unmanageable.

What Is Seasonal Depression?

Seasonal depression, or seasonal affective disorder (SAD), is a type of depression that occurs in a predictable seasonal rhythm.

Symptoms most often begin in the fall or winter and improve in the spring or summer. So, seasonal depression isn’t just about hating the cold. It can impact how a person feels, thinks, sleeps, eats and acts during the day.

What Are the Early Signs of Seasonal Depression?

Symptoms may develop gradually and initially resemble ordinary tiredness or difficulty adjusting to a new season.

Common signs include:

• Persistent sadness or emotional heaviness

• Losing interest in enjoyable activities

• Sleeping longer but still feeling tired

• Difficulty waking up

• Low energy

• Trouble concentrating

• Increased appetite or carbohydrate cravings

• Irritability

• Social withdrawal

• Feelings of hopelessness or worthlessness

Symptoms can vary from person to person. The most obvious warning is often a cyclical pattern, where emotional changes return around the same time of year and start to interfere with daily life.

Why Can Fall Affect Mental Health?

Researchers don't cite one cause of seasonal depression. But decreasing daylight can impact the body’s internal clock and substances that control sleep and mood.

Morning light helps set the circadian rhythm which informs the body when to be up and when to be ready for sleep. Later sunrises and earlier sunsets can upset this pattern and make you feel fatigued, over-sleep and find it hard to keep to a typical routine.

You may also get less exercise, outdoor activity and social engagement in autumn. Seasonal depression isn’t necessarily brought on by these changes, but they can disrupt routines that used to support mental health.

Is It Seasonal Depression or the “Winter Blues”?

A lot of people have low energy in fall and winter without having seasonal affective disorder.

The “winter blues” could be momentary weariness, boredom or displeasure with the weather. A person can usually continue to work, maintain relationships and enjoy typical activities.

Seasonal depression is more persistent and distressing. Symptoms may interfere with employment, self-care, focus, relationships, or the capacity to enjoy things.

Treatment may include psychotherapy, antidepressant medication, bright-light treatment, or a combination of these approaches.
