Seasonal Affective Disorder and Its Impact on Airmen

By Ms. Sofia Schatz, Staff Writer

Seasonal changes often bring cooler weather, holiday traditions, and time with family and friends. However, for some people the change in seasons can also bring unexpected emotional challenges. Seasonal Affective Disorder, commonly known as SAD, is a form of depression that follows a seasonal pattern and can impact daily life, mood, and overall mental fitness.

According to the National Institute of Mental Health, SAD affects an estimated ten million people in the United States. Symptoms often appear during the fall and winter months when daylight hours are shorter, and they typically improve in the spring and summer. Though many people experience mild mood changes during seasonal transitions, SAD can be more severe and may affect a person’s ability to function normally.

For Airmen, maintaining mental health and resilience is essential for both personal well-being and mission readiness. Recognizing the signs of seasonal depression early and understanding available resources
can help individuals seek support when needed.

Recognizing the Signs

Seasonal Affective Disorder is considered a type of depression with recurring seasonal patterns. The most common form is winter-pattern SAD, sometimes called winter depression, which begins in late fall or early winter and improves as daylight increases in the spring. A less common form, summer-pattern SAD, can occur during the warmer months.

Common symptoms of SAD may include:

  • Feeling depressed most of the day, nearly every day.
  • Losing interest in activities once enjoyed.
  • Changes in appetite or weight.
  • Trouble sleeping or oversleeping.
  • Low energy or fatigue.
  • Difficulty concentrating.
  • Feelings of hopelessness or worthlessness.

Winter-pattern SAD may also involve oversleeping, increased cravings for carbohydrates, weight gain, and social withdrawal. Summer-pattern SAD may include insomnia, restlessness, anxiety, and reduced appetite.

These symptoms may occur on a spectrum, ranging from mild mood changes to more serious mental health concerns. If symptoms worsen or include thoughts of self-harm or suicide, seeking professional help is strongly encouraged.

Why Seasonal Changes Affect Mood

One of the key factors contributing to SAD is reduced exposure to sunlight. Shorter daylight hours can disrupt the body’s internal clock, also known as the circadian rhythm, which helps regulate sleep and mood.

Sunlight also influences chemicals in the brain, such as serotonin, which plays a role in regulating mood. When sunlight decreases, serotonin levels may drop, potentially triggering symptoms of depression. Changes in sunlight can also affect melatonin, a hormone that helps control sleep patterns.

These biological changes, combined with environmental factors such as colder weather and spending more time indoors, can contribute to seasonal mood changes.

Supporting Mental Fitness

For Airmen, maintaining mental fitness is just as important as physical readiness. Developing healthy routines and recognizing mood changes early can help reduce the impact of seasonal depression.

Helpful strategies include:

  • Maintaining a consistent sleep schedule.
  • Exercising regularly and staying physically active.
  • Eating balanced, nutritious meals.
  • Staying socially connected with friends, coworkers, and family.
  • Keeping a structured daily routine.

Creating a positive work environment and maintaining an organized workspace can also help reduce stress and prevent feelings of being overwhelmed.

Practical Strategies for Managing SAD

Several strategies can help reduce the effects of SAD.

Light therapy is one commonly recommended approach. Special lamps that emit bright light can mimic natural sunlight and may help regulate mood and sleep cycles. Exposure to bright light for a set period each day has been shown to reduce symptoms for many people experiencing seasonal depression.

Other helpful practices may include:

  • Spending time outdoors when possible.
  • Taking vitamin D supplements if recommended by a healthcare provider.
  • Staying hydrated and maintaining healthy nutrition.
  • Practicing relaxation or grounding techniques.
  • Finding hobbies or activities that boost mood.

Several Air Force installations have also introduced wellness initiatives, such as light therapy stations and resilience programs, to help Airmen cope with seasonal stress and maintain mental well-being.

Local Support and Resources

Airmen experiencing symptoms of seasonal depression are encouraged to seek support early. Talking with a trusted friend, coworker, or supervisor can be an important first step.

Several resources are available to help, including:

These resources offer confidential support and guidance for those who may be struggling.

SAD is common, and experiencing it does not mean someone has to face it alone. Early awareness, healthy routines, and access to support services can help Airmen maintain resilience throughout the changing seasons.

By recognizing the signs and prioritizing mental fitness, Airmen can take proactive steps to protect their well-being and remain ready to accomplish the mission.
