Christie Brinkley, who has graced magazine covers for nearly five decades, is often asked about her beauty secrets. But Brinkley, 67, says her best tip isn’t about beauty and has nothing to do with products or special diets.

It’s all about gratitude, she says.

“Every day I count my blessings,” Brinkley told CNBC Make It. “Because some days may be better days than others, but when I’ve counted my blessings, I feel like it’s a pretty good day.”

Taking time each day to practice gratitude gives her extra health, energy, and productivity, she says. “I always tell my kids to do it [it] because it really cleans up the mess and gives you focus. “

Many studies over the past decade have shown that those who consciously count their blessings tend to be happier and less depressed. According to Glenn Fox, an expert in gratitude at the University of Southern California’s Marshall School of Business, there are also a variety of other benefits associated with gratitude, including better sleep, more exercise, and less inflammation and blood pressure.

Brinkley says she practices gratitude all day long and when something bothered her. “As soon as something’s annoying, I put it into perspective,” says Brinkley, who spoke to CNBC Make It while promoting beauty tool brand SBLA.

That’s why “I just don’t mind things that much because I have a pretty good idea of ​​what really matters,” she says.

Brinkley has been promoting the practice of gratitude for years.

When she hit the headlines in 2017 for gracing the cover of Sports Illustrated with her two daughters Alexa Ray Joel, now 35, and Sailor Brinkley-Cook, now 23, aged 63, she told WWD that gratitude is a big part of her Formula for staying healthy and happy.

“Eating right, exercising, and sunscreen are the three things that affect your outcome more than anything, as well as a healthy attitude,” she said. “An attitude of gratitude is the formula for a happy life, and I firmly believe that happiness contributes to your well-being and health.”
