Overview
SAD Light Therapy Lamps mimic natural light, and their purpose is to improve the mood of people who suffer from SAD – Seasonal Affective Disorder. Classified as a major depressive disorder, people with SAD experience low mood during the change of the seasons.
SAD is most likely to occur in fall and winter when the days are shorter and there’s less sunlight, meaning one reason for its appearance may be lack of sufficient light.
According to clinical psychologist Michael Breus, PhD, “There is substantial data to suggest that light therapy will be beneficial to those with SAD, in terms of improvement of symptoms.” [1]
Breus explains further, “There are a few theories that are …at play with this particular type of therapy: consistent therapy (timing of administration) will lead to help align your circadian rhythms, the therapy itself is thought to affect serotonin production and balance it (many people with any form of depression will have serotonin issues), and it increases alertness.”
Adding to this, Aja Chavez, National Executive Director of Mission Prep Healthcare, highlights the tangible benefits of consistent light therapy:
“I’ve seen remarkable improvements in my clients who consistently use SAD lamps for 30 minutes each morning. One patient reported feeling more energized within just two weeks of starting treatment.”
This emphasizes that regular and timely use of SAD lamps not only aligns biological rhythms but also delivers noticeable improvements in mood and energy levels, often within a short period.

How Do SAD Light Therapy Lamps Work?
A light therapy lamp for depression emits white light which simulates the sunlight that we miss in the darker months of the year, and it should improve mood in people who suffer from Seasonal Affective Disorder. Light therapy lamps mimic natural sunlight, helping to regulate your body’s internal clock and boost mood-enhancing chemicals. According to the Mayo Clinic, this process positively influences brain chemicals linked to mood and sleep.
A study by Gagan Virk, MD and Gloria Reeves, MD, et al published in the International Journal of Disability and Human Development gave patients light therapy lamps for several weeks, and concluded that there was immediate improvement in mood after even one 20 minute session [2].
The light increases the production of the brain neurotransmitter serotonin which plays a key role in mood regulation. These lamps also balance the production of the hormone melatonin which controls circadian rhythms and sleep.
The human circadian rhythmA randomized controlled trial by Michelle Rissling and Lianqi Liu, et al published in Frontiers in Neuroscience found that administration of light therapy every morning improved sleep and slowed nighttime wakeups in women going through chemotherapy for breast cancer [3].
Family physician Dr. Robert Cain, MD explains: “Long periods of dark and a lack of sun exposure gets your sleep-wake rhythm thrown off and sun lamps help reset it,” [4].
The increase in serotonin and melatonin should improve sleep, alleviate depression, ease jet lag, and may also have benefits for people with dementia. The therapy uses devices that emit light roughly 20 times brighter than typical indoor lighting.
Clinical psychologist Nick Bach highlights a key tip:
I recommend using a SAD lamp with at least 10,000 lux brightness. A typical usage guideline is around 20-30 minutes each morning, ideally upon waking, to simulate natural daylight exposure. Placement should be about 16-24 inches from the face but without directly staring at the light source.
We documented the red light therapy for depression article as it also helps in improving mood, reduces anxiety, and promotes mental health.
An article in the Journal of Alzheimer’s Disease by Nicholas Hanford and Mariana Figueiro discussed the use of light therapy in the treatment of dementia [5].
