Is humm safe? +
Yes! Humm is based on more than 30 years of scientific research using non-invasive transcranial stimulation across many of the world’s top universities, with over 30,000 participants.
Humm uses an exceptionally small electric current (less than both 2 milliamps) to gently stimulate the brain, in a way that was carefully developed by neuroscientists over years of experimentation. To give you a sense of scale, the current that humm applies is about 1/100th of the electricity already flowing through the brain, and about 1/20th of the energy absorbed by the brain during a 15 minute phone call.
Over 30 years of study and review, the safety and effectiveness of tACS has been extensively reviewed, and its use among healthy people has been cleared by the FDA. No serious negative effects have ever been observed when using tACS with more than 30,000 participants, nor among any users of humm or any of the several tACS devices currently on the market. On extremely rare occasions, users have experienced minor temporary effects of discomfort, including a mild headache or dizziness. If this happens, remove the patch and try again later, but please make sure to consider other potential causes such as dehydration and caffeine.
What should I expect to feel when I use humm? +
tACS has often been described by initial users as a slight tingling, pulsing or pressure sensation. When you first use humm, the feeling may be unfamiliar to you, but it becomes less noticeable over time.
You may also perceive a slight flashing in your periphery, a very common effect called Phosphenes. These are tiny electrical currents reaching the retina - and they're completely normal and harmless. What you see is the same thing that happens when you close your eyes and rub them with your finger.
No serious negative effects have ever been observed when using tACS over 30 years of study with more than 30,000 participants, nor among any users of humm. On extremely rare occasions, participants have experienced minor temporary effects of discomfort, including a mild headache or dizziness. If this happens, remove the patch and try again later, but please make sure to consider other potential causes such as dehydration and caffeine.
Is there anyone who shouldn't use humm? +
Humm is NOT intended for use by persons who are under the age of 18, have an implanted metal or electronic medical device in the head or neck, have a pacemaker, have a history of seizures, are pregnant, or have undergone any brain surgery. Please consult your physician if you believe any of these apply to you or if you have any concerns.
Why is humm a subscription service and how does that work? +
Humm operates on a subscription model that is renewed monthly and can be cancelled anytime. This subscription model allows us to provide you with increased convenience as well as cost savings and discounts. With your subscription, you will receive an instruction manual, a discount code, alcohol wipes, and enough patches to last the average user one month. We are also currently considering adding expanded subscription options for those who require more than 12 patches per month.
How does humm reduce its environmental impact? +
When you return your patches to humm, we take special care to repurpose and recycle the electronics from every patch into manufacturing new ones. We are also currently experimenting with the incorporation of more eco-friendly fabrics that not only reduce our environmental footprint but maintain comfort against the skin.
