Emma Baumert admits that when she first put on the high-tech headband she felt silly. “But I also felt so cool wearing it, because I’m such a nerd.”

The 24-year-old from Illinois is a member of the USA Bobsled/Skeleton development team.

An all-round athlete, she is also a qualified weightlifting coach, and this year gained a masters degree in exercise physiology.

The headband she now uses is a neurofeedback or EEG (electroencephalogram) device. Growing in popularity among sports people, they measure the wearer’s brainwaves.

As a stressed brain gives off more waves or signals, due to increased electrical activity, the idea is, that, together with meditation, the headbands can help the user train him or herself to be calmer. And then in turn boost their performance.

But are such devices, which are otherwise used by doctors to test for conditions such as epilepsy and strokes, really beneficial in helping people to reduce their stress?

Ms Baumert says she wanted to find out after trying out a headset called FocusCalm two years ago. “After using it myself, I was like ‘I want to do more research on this’,” she says.

So, she contacted the firm behind the product, Massachusetts-based BrainCo. Given her relevant university studies, and her weightlifting and winter sports participation, they invited her to become a part-time, but paid, researcher for a few months in 2020. and again earlier this year.

Ms Baumert is now convinced the device works. “I got to visualise and learn how to have better control, and what training I need to do to get into a more relaxed state, while still being able to have very high explosive power output.”

Max Newlon, president of BrainCo, explains that the headband uses an AI (artificial intelligence) software algorithm to monitor 1,250 “data points” in a person’s brainwave signals. Connected to a mobile phone app, it then scores them on a scale of 0 to 100, with 100 being calmest.

Most of the time the average person apparently hovers around the 50 mark.

“It’s a passive measure, there’s nothing going into your brain,” says Mr Newlon, who first started working on the technology in 2015. “We have people doing all different types of experiments, like spending time with their family… to learn about themselves and discover what puts them in that focused and calm state.”

Like physical exercise making the body stronger, Mr Newlon says that people can learn to relax their brain, and that once the skill is acquired, it sticks.

Another EEG headband developer, Canadian firm InteraXon, created its product – the Muse – in 2014.

It is also designed to help make you feel calmer, and in turn support meditation or better sleep.

In addition to measuring brainwaves it records heart rate, speed of breathing, and a person’s posture. And it comes with an app that plays soothing sounds, such as that of a rainforest.

Derek Luke, chief executive of InteraXon, says its customers are either “trying to address an issue in their life”, such as stress and anxiety, or “proactively trying to improve” at something, such as their performance in a certain sport.
