2 longevity secrets no one talks about: Because you can’t sell products around them, says fitness coach

While we may think nutrition and workouts are key factors for longevity, a fitness coach shared that they are not. According to him, longevity lies in looking after two crucial factors that most people don’t talk about because they can’t sell too many products around them.

For most people, the aim of staying fit implies having a long and healthy life. While diet, nutrition, and workouts play an important role, fitness coach Luke Coutinho shared that the secret to longevity goes beyond these. No one talks about the two key factors that are game-changers because they don’t bring commercial gains.

In his Instagram post, the integrative lifestyle expert said, “Powerful medicines are free; all we need to do is plan our day a little better and put in a bit of effort. It’s free, but at the end of the day, most humans take for granted what is free.”

He shared how stepping out in the morning to get some sunlight is part of the solution. “If there’s no sun or the sun is behind the clouds, getting natural light in your eyes and on your skin in the morning, even if it’s just for 10 minutes before those phones come on, is magic.”

Luke said this helps a great deal in regulating hormones: “Think about insulin, thyroxin, estrogen, testosterone, all of these things.” He highly recommended going back to basics: “Every single day, more and more buried scientific research is coming to light. We think it’s about nutraceuticals, superfoods, or all these complications, but the fundamentals lead back to how we behave.”

Addressing the two key factors that are most important in the whole game of health and longevity, he said, “It’s how you manage chronic stress and how deep your sleep is. I know you can’t sell too many products around this, and that’s why no one talks about it.”

The fitness coach shared that everyone wants to focus on nutrition, but it’s practically useless without great sleep and without managing chronic stress. “It’s the same with exercise, supplements, saunas, and cold baths. These are all good, they’re must-haves, but if we think they’re the most important, we’re mistaken. The actual science shows that chronic stress is the number one hijacker of our biology and ageing. And along with chronic stress, sleep deprivation, getting less than six hours of sleep a night, is just as damaging.”

While Luke commended the effort and money people put into taking care of their health, he advised that it’s best to start by addressing chronic stress and finding small ways to improve sleep. He called these “the magic of lifespan and the foundation of everything in the human body.”
