When the seasons change and days become shorter, we’re exposed to less sunlight. Additionally, because it’s already dark when we get off work, we’re no longer exercising outside as often, opting instead for indoor exercise equipment. As a result, our bodies often become deficient in vitamin D and serotonin, which can lead to a condition known as seasonal affective disorder. Commonly referred to as SAD, seasonal affective disorder is a type of depression that shows up around the same time each year. Most people with SAD start experiencing symptoms in the fall that continue into the winter months. Although less common, but still possible, SAD can also be present in the spring and early summer. Regardless of when it exists, it can deeply impact one’s overall health and wellness.

One of the recommended ways to treat SAD is with light box therapy. A SAD light delivers a dose of nutrients through a UV-free LED bulb. Usually in the morning, one sits in front of a light therapy lamp that’s placed in a peripheral view, not looking directly into the device. The length of time per session starts at around 5 minutes and increases gradually to 15 minutes maximum. Be sure to read the user’s manual for detailed instructions. There are various types of SAD lamps, which is why it’s wise to review the specifications to see the strength of light each model emits. For example, a wake-up light alarm clock simulates sunshine but has less strength than a device designed specifically for SAD light therapy. While it’s not a complete replacement for the benefits of outdoor recreation, there are many advantages to having a sunlight lamp to help ease the symptoms of seasonal affective disorder.
