Understanding Seasonal Depression
As the days get shorter and colder in the fall and winter months, many people start experiencing symptoms of low mood, fatigue, changes in appetite and sleep patterns. This condition is known as seasonal affective disorder (SAD) or seasonal depression. It is estimated that around 5% of adults in the U.S. experience SAD every year.
The main cause of seasonal depression is believed to be the lack of natural sunlight in the fall and winter months. The change in sunlight exposure impacts serotonin and melatonin levels in the brain, which regulate mood, sleep and appetite. Some people seem to be more sensitive to these light-related changes, making them more prone to seasonal depression.
Symptoms of seasonal depression often start in the late fall or early winter months and go away during the sunnier days of spring and summer. However, some people experience seasonal depression in the summer too. The key factor is change in seasons, not necessarily cold or dark weather.
Common Symptoms of Seasonal Depression
Many of the symptoms of seasonal affective disorder mirror clinical depression and include:
- Feeling depressed, sad, down or hopeless
- Losing interest in activities you used to enjoy
- Having low energy and feeling fatigued
- Sleeping too much or trouble sleeping
- Experiencing changes in appetite and weight
- Difficulty concentrating or making decisions
- Feeling sluggish or agitated
- Having frequent thoughts of death or suicide
In addition to these typical depression symptoms, seasonal affective disorder also causes some specific symptoms related to changes in seasons like:
- Craving carbs and sweets
- Gaining weight
- Oversleeping
- Social withdrawal

Living with Seasonal Affective Disorder
If you have seasonal depression, there are some lifestyle changes and self-care strategies you can adopt to ease your symptoms:
Boost Light Exposure
Since lack of sunlight triggers SAD, increasing light exposure is key. Use a light therapy lamp, maximize natural light, and spend time outdoors even on cold or cloudy days.
Exercise Regularly
Physical activity has been shown to improve depression by releasing feel-good endorphins and boosting serotonin levels. Aim for 30 mins of exercise daily.
Try Mind-Body Practices
Yoga, meditation and breathing exercises can help relieve stress and anxiety. Apps like Calm, Headspace and Insight Timer offer guided sessions.
Socialize More
Loneliness and isolation tend to make SAD worse. Make plans with supportive friends and family. Join a seasonal depression support group.
Improve Your Sleep
Lack of sunlight can disrupt circadian rhythms. Stick to a regular sleep-wake schedule and limit electronics use before bedtime.
Watch What You Eat
Craving carbs and sweets is common with SAD. Limit sugar intake, eat more protein and fruits/veggies to stabilize mood and energy.
Consider Antidepressants
If symptoms are severe, ask your doctor about antidepressant medication like SSRIs or bupropion to manage SAD.
While living with SAD has its challenges, using healthy lifestyle habits, light therapy and psychotherapy can help reduce the impact on your daily life. With time, your symptoms should start improving as the seasons change.
