For many of us, it’s not uncommon to feel sluggish or melancholy during late fall and winter, as these months usually consist of shorter days and limited exposure to natural sunlight.

In a previous blog post, we shared tips on how to overcome Seasonal Affective Disorder (or SAD), a form of depression that affects a person’s mental health and occurs after a significant change in seasons. And one of the ways we discussed managing your SAD symptoms was through the use of artificial lighting, also known as light therapy boxes.

To give you a better understanding of how light therapy works and the benefits of light therapy, here’s everything you need to know.

What Is Light Therapy and How Does It Work?

Light therapy involves the use of a light therapy box that helps create the illusion of natural sunlight. It sounds simple enough, but experts believe this type of lighting device can actually influence the chemicals in your brain that affect your sleeping patterns and mood. Therefore, its daily exposure may help minimize your depression-like symptoms (Mayo Clinic).

How it Works:

Your treatment may begin as early as fall, when the days start to get shorter and your symptoms begin to affect your mental health and social behaviors (i.e. lack of motivation, feeling tired, sleeping in longer, etc.). Your doctor may prescribe 15-30 minutes (or more) of light box therapy each day, beginning in the early hours to give your brain and body the illusion of waking up to natural sunlight.

The duration of time you spend each day performing light therapy will depend on the strength of your natural light lamp and your individual needs.

Benefits of Light Therapy

Experts believe that light therapy can help improve a person’s serotonin levels, which are responsible for helping your brain and body regulate sleep, mood, memory, and other essential functions:

“…a lack of adequate sunlight causes the body to dial up the production of SERT, a protein that is responsible for transporting the neurotransmitter serotonin in and out of the brain. As SERT production increases, the amount of serotonin available in the brain decreases. Low levels of serotonin are strongly associated with depressive symptoms,” (Psychology Today).

Light therapy is also believed to help manage other types of depression symptoms, sleep disorders, and certain skin conditions (Mayo Clinic).

Types of Natural Light Lamps

Though relatively safe, light box therapy can cause different side effects, including headache, nausea, and eyestrain (Psychology Today); therefore, you’ll want to speak to your mental health provider before beginning light therapy to help you understand the amount of daily exposure recommended to help manage symptoms and which natural light lamp is best for your condition.
