Kate Middleton has been worried for her husband Prince William and has now urged him to make a major lifestyle change.
According to Radar Online, the Princess of Wales has encouraged William to embrace cold-water plunges as a way to cope with rising stress during a challenging period for their family.
An insider told the publication that Kate genuinely believes the bracing dips help regulate the nervous system.
One insider said her advice came from concern, noting she wanted William to build resilience, not just fitness.
“Catherine sincerely believes these bracing cold dips help steady her nervous system,” the source said.
They added, "When she urged William to try it, it wasn't merely about fitness but about building resilience.
“She felt it could offer him a way to manage stress during an especially challenging time for their family."
As for the Prince of Wales, a source said he sees the new routine as part of his effort to remain a steady presence for Kate and their children, Prince George, Princess Charlotte and Prince Louis.
"He understands he needs to remain the steady point for his children and for Catherine. If this helps him regroup, even if it still feels tough, he's determined to stick with it,” they said.
Previously, Kate has admitted William’s love of motorcycles “terrified” her, while William later acknowledged fatherhood forced him to “tone it down.”
"He's still riding it. It always fills me with horror when he goes out on it. I'm terrified. Hopefully, I'm going to keep George off it,” she said while vising Dundee, Scotland, in 2015.
William later said, "I'm a dad of three. I have to tone it down. I miss the big trips, for me biking was always about being with everybody else."
