How 40Hz Light Therapy Works

We all have gamma rhythm in our brains that is responsible for learning, memory, and cognitive function. A healthy brain has a gamma frequency of 30-100Hz. For people with cognitive decline, this rhythm deviates.

Ongoing research shows that 40Hz light therapy is a noninvasive method of stimulating the brain’s activity and rejuvenating healthy brain rhythm.

40Hz light creates 40 flashes per second. This frequency is known to improve mental acuity, memory, and attention. 40Hz visual stimulation, given one hour a day for 6 months, had dramatic positive effects on brain function leading to 65% reduction in whole brain atrophy and dramatic improvement in sleep patterns.

As part of a healthy lifestyle, it is recommended as a passive therapy for those who want to prevent Alzheimer’s disease. Daily exposure for one hour per day can complement your regular routines like reading, watching television, answering emails, or preparing meals.

Experts agree that new approaches to Alzheimer’s therapies are needed, including noninvasive, drug-free solutions like 40Hz therapy that meet today’s dynamically aging population.


Since the first day of using BEACON40, there has been a dramatic shift.

“My wife was diagnosed with early onset Alzheimer’s three years ago. While her symptoms are still comparatively minor to most, her moods can be pretty awful. She loves having it on, and  next to her in our living room while watching TV. She began counting down the days that we had not had an argument and is acutely aware of its benefits. She’s simply happier.”

We’ve seen cognitive improvement.

“Thank you so much. I also wanted to let you know that we have noticed a cognitive improvement with my mother when using the light therapy regularly so thank you for your product!”

She’s sleeping and feeling better.

“Bought the light for my mom who is 73 and has experienced cognitive decline. I let her know about the importance of the light, and we did some research about 40Hz. To see her reaction when I was reading the articles to her made me smile.”

The Best Way to Beat Alzheimer’s Is Prevention

Using noninvasive solutions like 40Hz light stimulation as part of your daily wellness routine can rejuvenate brain rhythm and boost your memory and attention.

There is a hereditary component to Alzheimer’s. People whose parents or siblings have the disease are at a slightly higher risk of developing it themselves. However, a growing body of research shows that inactivity, depression, obesity, hypertension, diabetes, smoking, social isolation, and other demographic factors raise the risk of developing dementia. Almost all of these factors are modifiable, leading experts to believe that the best way to avoid Alzheimer’s is by prevention. 

Although Alzheimer’s risk goes up with age, there is much that can be done to work toward prevention, regardless of where you are in life’s journey. Observational studies show that adopting wellness routines—including regular physical activity, a good diet, taking on new mental challenges, and maintaining strong social connections—helps maintain cognitive health. Further research shows that individuals who follow routines that involve all of these habits may even regain mental capacity. 

It’s never too early to start adopting daily habits for brain health.

BEACON40 is a noninvasive method of stimulating the brain’s activity and rejuvenating healthy brain function. The lights deliver pulsing at 40Hz. That’s 40 flashes per second. Brain waves in this frequency are associated with improving mental acuity, memory, and attention. It is recommended as a passive therapy for those who want to prevent cognitive decline or improve sleep and mental acuity.

Daily exposure for one or more hours per day can complement your regular routines like reading, watching television, or answering emails.

Both the BEACON40 Personal and BEACON40 Surround are noninvasive and are designed to complement, not interfere, with your existing daily routines. The difference is only in the number of lights in each kit.

BEACON40 Personal has one light. It is designed to be used in more intimate locations like in an office or on a vanity. Most place it on a desk and use it while answering emails or searching the web.

BEACON40 Surround includes two lights and is designed for larger spaces such as a living room or kitchen. Set it up around your TV, with one light on each side, or use it in a shared home office or living room.

An abundance of naturally occurring amyloid plaques in the brain can be responsible for interrupting healthy brain rhythms. Recent research has indicated that these plaques begin to build up in the brain 15 to 20 years before any behavioral symptoms of Alzheimer’s become apparent. Just like you brush your teeth to keep plaque away, it’s beneficial to have a proactive routine to maintain healthy brain function. Research has shown that gamma light therapy may operate both to reduce the amount of amyloid plaque buildup and to excite healthy brain function. The use of BEACON40 lights may have a positive effect in the prevention of the development of Alzheimer’s in at-risk individuals who have not yet been diagnosed with the disease.

BEACON40 represents the fast-tracking cutting-edge, scientific research to create safe, easy-to-use wellness routines for enhanced brain health. BEACON40 is modeled after ongoing human trials coming from leading brain health institutes including MIT, Georgia Tech, and other reputable resources. Please discover more scientific references and research articles here.

BEACON40 is designed to be convenient and easy to use. For recommended use, sit comfortably with the lights in your peripheral view about 3 to 12 feet away for at least one hour per day. The lights should be in your peripheral view—that means you must have your eyes open for them to be effective but you should not look directly into the lights. Adjust your settings according to your preferences.
