Talk about “sleepmaxxing.”
More people are looking to get the most out of their nightly slumber, turning to high-tech mattresses and bedding to track their sleep data and achieve a perfect night’s rest.
Now, the brand that once described itself as a “sleep fitness” company has partnered with the “immortal uncle” to offer a way to see how fast you’re aging while catching some Z’s.
Eight Sleep, maker of the buzzy Pod bed cooling system, has just added a biological age feature to help users better understand not just how well they’re sleeping — but also how well they’re aging.
The company developed the latest tech with biohacker and longevity mogul Bryan Johnson, a longtime advocate of prioritizing sleep who has used the Pod for years.
“Bryan has spent years focused on measuring the factors that influence the pace of aging,” Matteo Franceschetti, co-founder and CEO at Eight Sleep, told The Post.
“That perspective helped shape how we think about making longevity data more accessible and useful in everyday life.”
The Eight Sleep Pod system consists of cooling pillow covers, a mattress cover to track biometric data, a hydro-powered blanket that connects to the cover and a hub, which powers the system.
Using sensors built directly into the Pod mattress cover, the new feature measures several biological signs of aging — including heart rate, heart rate variability, respiratory rate, sleep stages, and sleep duration — and can account for individual metrics of two people in the same bed at the same time.
Users also have the option of connecting a wearable fitness tracker, like an Apple Watch, to add data from their daytime activities and medical records for a more comprehensive picture.
Unlike chronological age — the time that’s passed since a person’s birth — biological age measures the functional condition of a person’s cells, tissues and organs. Several factors play a role in how well someone ages biologically, including genetics, weight, environmental exposures and lifestyle habits, such as diet, exercise and, of course, sleep.
“Because it is part of the bed, the experience is effortless,” Franceschetti explained. “You simply sleep in comfort while the Pod builds a continuous picture of how your body is functioning night after night.”
To ensure the cover’s sensors provided the most accurate results, measurements were validated against clinical gold standards.
For instance, sleeping heart rate was 99% accurate compared with an ECG, while respiratory rate was 98% accurate compared with respiratory inductance plethysmography, a tool used to measure lung volume and breathing patterns.
“For Biological Age specifically, we trained a new health foundation model using data from more than 100,000 participants and 2.7 million hours of biometric data collected during sleep,” Franceschetti explained. “That accuracy is the foundation for Biological Age.”
Along with biological age, the system also focuses on speed of aging, or the estimated pace at which the body is aging relative to calendar time.
While Biological Age and the Pod aren’t meant to replace clinical care, consistency is key to fully understanding how someone’s health is “changing over time relative to their own baseline, while also comparing those patterns with people of similar age and gender,” according to Franceschetti.
“I think Eight Sleep customers will love the Biological Age because it can help them build intuition around how their lifestyle choices affect their health,” Johnson said in a press release from Eight Sleep.
The most current Pod system runs for $2,999 with a five-year warranty. Eight Sleep offers a 30-night risk-free trial, as well as free shipping and free returns.
