Understanding seasonal affective disorder (SAD): symptoms, causes and solutions

What is Seasonal Affective Disorder (SAD)?

Seasonal Affective Disorder, commonly referred to as SAD, is a type of depression that follows a seasonal pattern. While symptoms typically emerge during the winter months, when daylight hours are shorter, it is important to recognise that SAD can manifest at any time of the year, especially when weather conditions lead to prolonged periods of grey skies or reduced sunlight, such as in the unusually grey summers England has experienced recently! The condition can impact individuals differently, with some experiencing mild symptoms while others may find their daily functioning significantly impaired.

Symptoms of SAD

The symptoms of SAD can range from moderate to severe and often include:

• Persistent Low Mood: A feeling of sadness, hopelessness, or emptiness lasting for much of the day.
• Loss of Interest: A notable decrease in interest or pleasure in activities that were once enjoyable.
• Changes in Sleep Patterns: Increased sleepiness or insomnia; some individuals may have difficulty getting out of bed in the morning.
• Fatigue or Low Energy: Feeling sluggish or lethargic, often resulting in diminished productivity.
• Weight Fluctuations: Changes in appetite, such as increased cravings for carbohydrates or sweets, which can lead to weight gain.
• Difficulty Concentrating: Trouble focusing, making decisions, or remembering details.
• Social Withdrawal: A tendency to isolate oneself from friends and family.

Understanding that these symptoms can have a significant impact on one’s personal and professional life is crucial. Recognising the condition and seeking appropriate interventions can lead to better management of its effects.

What Can I Do to Help Manage SAD?

Despite the challenges posed by SAD, there are various strategies that can help manage its effects and improve emotional well-being throughout the year. Here are several practical steps to consider:

1. Get Natural Sunlight: Aim to spend time outdoors during the day whenever possible. Natural light plays a significant role in regulating our circadian rhythms and mood. Even a brief walk in the sunlight—ideally 15 to 30 minutes—can positively impact your mood and energy levels.
   ‍
2. Light Therapy: Starting your day with 30 minutes of light therapy using a light box designed for SAD can be extremely beneficial. This therapy mimics natural sunlight, helping to alleviate symptoms by influencing brain chemicals tied to mood regulation. Consistency is key, so incorporating this into your daily routine can yield the best results.
   ‍
3. Reduce Blue Light Exposure: In today’s digital age, many of us are exposed to blue light emitted from screens in the evening. Reducing this exposure by at least one hour before bed can help improve sleep quality and overall well-being. Consider implementing a digital curfew, switching off devices, or using blue light filters on your screens.
   ‍
4. Take Vitamin D Supplements: Given that sunlight is essential for the body’s ability to produce vitamin D, particularly in winter months, adding a vitamin D supplement to your routine can provide a vital nutritional boost. It can help combat feelings of fatigue and support emotional health. Always consult with a healthcare professional to determine the appropriate dosage for your needs.
   ‍
5. Embrace Nature: Nature has a remarkable impact on mental health, regardless of one’s background or circumstances. Engaging with the outdoors—whether through hiking, gardening, or simply enjoying a park—allows the mind to reset. As someone who makes it a point to get outside every day, I can affirm that even short bursts of 10 to 15 minutes outdoors result in immediate improvements in mood and perspective.

The Research Behind Nature's Benefits

The research supporting the mental health benefits of nature is robust. Numerous studies have highlighted the positive impacts of exposure to green spaces, natural light, and outdoor activities on reducing symptoms of depression and improving overall emotional well-being. The mental clarity, stress reduction, and emotional resilience gained from connecting with nature cannot be overstated. I get outside every day, sometimes for just 10 minutes but I always without fail feel better afterwards.

If you or someone you know struggles with Seasonal Affective Disorder, it’s crucial to remember that you are not alone, and help is available. Implementing simple lifestyle adjustments and embracing the healing power of nature can significantly improve your mood and overall quality of life. Take small steps towards managing your symptoms, and be open to exploring various strategies until you find what works best for you.
