Bear Grylls has renamed his alarm clock “an opportunity clock” to avoid negative connotations.
The adventurer said that beginning the day with positive terminology has psychological and physiological benefits.
He believes that an object associated with the word “alarm” is not a healthy way to begin each day.
“My family takes the mick out of me a lot for the ‘opportunity clock’, but language is important,” said Grylls.
“How we speak to each other and ourselves is important. Words have power. It’s a choice to speak kindly and positively.”
Grylls said he had also reframed the experience of being out in the rain as something which is good for the soul.
“It can be brilliantly healing,” he said. “So many humans have an aversion to rain but I’ve learnt that, as long as you’re not in a suit, there’s something amazing about being out for five minutes in rain.
“Nature is always our best teacher.”
Valuing 'mental fitness'
The 48-year-old television star and Chief Scout has written a book, Mind Fuel, which draws on his survival experience to give tips on building resilience and reducing stress.
“You might go to the gym, but doing something for your mental fitness is important as well,” he told Radio Times.
“It doesn’t have to be hours of meditation, but five minutes of practical, simple things.
“Then you steadily build up robustness and strength over time.”
His advice includes having a cold shower every morning: “Even just 30 seconds at the end of your shower - whack it down to full cold to get that blast - gives your whole system a brilliant reset. It’s like nature’s defrag.”
Despite his gung-ho reputation, Grylls said it was important to show his vulnerable side and dispel the myth that he’s “great at stuff”.
“I struggle with people expecting me to be super-strong and brilliant all the time,” he told Radio Times.
“Life’s definitely not like that. The truth is, I’m not always strong and I’m not always great at stuff.
“I think it’s probably why I have anxiety about meeting lots of people. I don’t really enjoy the attention. I’m ever more aware of one’s frailties and failings.”
Grylls divides his time between a houseboat on the Thames in Battersea, south-west London, and a tiny island off the Welsh coast, and said he received an emotional boost from taking his dogs for a walk each morning.
“Whatever the weather, there’s something about breathing fresh air and feeling wet grass on your feet that really helps me,” he said.
