Seasonal affective disorder (SAD) is a type of depression that occurs at certain times of the year, typically during the fall and winter months when there is less natural sunlight. It is believed to be related to changes in the body's internal clock or circadian rhythm, as well as reduced levels of serotonin and melatonin, which are neurotransmitters that regulate mood and sleep.
Symptoms of SAD can include:

- Persistent low mood or sadness
- Loss of interest in activities once enjoyed
- Fatigue and anergia
- Difficulty sleeping or oversleeping
- Changes in appetite and weight, particularly craving carbohydrates
- Difficulty concentrating and making decisions
- Feelings of hopelessness or worthlessness
- Social withdrawal or isolation
- In some cases, anxiety or irritability
"Winter blues" are also a milder form of SAD that many may face during the winter months. The exact cause of SAD is not fully understood, but factors such as reduced sunlight exposure, changes in melatonin and serotonin levels, and a genetic predisposition may contribute to its development.
Treatment for SAD may include light therapy, where a person is exposed to bright artificial light for a designated amount of time each day, typically in the morning. Antidepressant medications, such as selective serotonin reuptake inhibitors (SSRIs), may also be prescribed. Additionally, counseling or talk therapy can be beneficial in helping individuals cope with the symptoms of SAD and develop effective strategies for managing their mood.
It's important to note that while SAD is most commonly associated with the fall and winter months, a less common type known as "summer depression" can occur during the warmer months.

Summer depression, also known as summertime sadness or reverse seasonal affective disorder (SAD), is a type of depression that occurs during the summer months. While most people experience increased happiness and energy during the summer, some individuals may feel sadness, irritability, and a lack of motivation during this time.
The exact causes of summer depression are not fully understood, but there are several factors that may contribute to it. One possibility is the change in routine and schedule that often occurs during the summer, which can disrupt sleep patterns and create feelings of restlessness. Additionally, the intense heat and humidity of summer may lead to physical discomfort and fatigue, which can contribute to depressive symptoms.
Other potential factors include feelings of loneliness or isolation due to the perception that everyone else is enjoying the summer while the person with summer depression struggles to find enjoyment. Financial stress from increased expenses related to travel, vacations, or social activities may also contribute to depressive symptoms.
Treatment for summer depression is similar to that for other types of depression and may include therapy, medication, and lifestyle changes. It is important for individuals experiencing summer depression to seek professional help, as it can be a serious condition that affects daily functioning and quality of life.
