(CNN) — You have a problem? There is probably a product that claims to solve it –– especially in the longevity space.
Social media, stores and online ads are abuzz with different regimens, items, supplements and strategies promising a longer life and everlasting beauty. It can be easy to get swept up in things that are just snake oil.
“There’s so much misinformation online about everything,” journalist Kara Swisher said. “There’s all these, essentially, wellness grifters that are giving people bad information, and these shortcuts that don’t really work.”
It is fine if the things that don’t work out are harmless, such as a terrible cauliflower bread recipe, she added, but “a lot of this stuff is real medical stuff that is not good for you or it’s costly for you, and I found that really offensive.”
In this week’s episode of “Kara Swisher Wants to Live Forever,” a CNN series airing at 9 p.m. ET Saturday that investigates longevity trends and science, Swisher parses out the grifts from the actual longevity tools.
Some of the things marketed toward people looking for longer, healthier lives are harmful; others are just expensive but not effective, she said. Then there are those that, even if they still need more research, may have something to offer.
Red light therapy
One of the latest crazes in beauty and longevity trends is red light therapy, but its impacts aren’t strictly just hype, said Dr. Zakia Rahman, a clinical professor of dermatology at Stanford University School of Medicine and affiliate faculty at the Stanford Center on Longevity.
Red light and less commonly talked about near-infrared light are specific wavelengths of light, which can send different signals to the body.
The idea is that the red light is converted to energy in the mitochondria, which if you remember from biology class are the powerhouse of the cell. While not known with certainty, researchers believe that exposing the cells to red light wavelengths helps improve cell performance and resilience and reduces inflammation, said Dr. Praveen Arany, associate professor of oral biology at the University at Buffalo School of Dental Medicine in New York.
The scientific evidence is increasingly supporting the assertion that red light therapy can help with skin texture and hair growth, which has caused a boom in at-home devices for cosmetic purposes, Rahman added.
Studies are being done to look at a host of other potential benefits such as treating chronic pain, Parkinson’s disease and Alzheimer’s disease, Arany said.
Going beyond the surface and treating deeper parts of the body still need more data, however. Protocols such as how to administer the light, exactly which wavelengths to use and for what amount of time still haven’t been established, he said.
There are two ways of administering red light therapy: lasers, which are typically in a doctor’s office, and LED panels, which many people are buying for their homes. The LED option has less potential for damage if used incorrectly, but there is also less quality control in the marketplace, Arany said.
If you want to try red light therapy and feel confident about the machine you are purchasing, Rahman recommends starting by looking for devices that have clearance from the US Food and Drug Administration.
But remember, she said, red light therapy isn’t a magic elixir, and you won’t use a device once and wake up the next day looking 10 years younger with a full head of hair. Devices such as these take consistent use over a period of months to see results, Rahman said.
Sweating in a sauna
Sweating it out in a sauna is another wellness strategy that isn’t purely snake oil, Swisher said.
“If you don’t overdo it, you get plenty of water. It’s great. It’s actually on
