Light Therapy Lamps

When the seasons change and days become shorter, we’re exposed to less sunlight. And because it’s often already dark when we leave work, exercising outside can be more difficult. As a result, our bodies can 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 tends to show up around the same time each year. Most people with SAD start experiencing symptoms in the fall that continue into the winter months, and SAD can also be present in the spring and early summer, although it's less common. Regardless of when it exists, it can deeply affect one’s overall health and wellness.

One of the ways technology is being used to treat SAD is through light box therapy through a UV-free LED bulb. Light therapy sessions usually take place in the morning, when a user will sit in front of a light therapy lamp that they place in a peripheral view (rather than looking directly into the device). The length of time per session starts at around 5 minutes and increases gradually to a 150-minute maximum. Be sure to read the user’s manual for detailed instructions. There are several types of SAD lamps, which is why it’s wise to review the specifications to learn the strength of light that 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 benefits to light therapy that may help ease the symptoms of seasonal affective disorder.
