Eamonn Holmes took a cheeky swipe at his wife Ruth Langsford as he discussed napping with his co-host Isabel Webster on Tuesday.
The GB News presenters discussed a new sleep study on how napping for 40 minutes every day can help with brain growth.
Isabel revealed: "At least if I set an alarm for an hour, which is what I tend to do on the days when I am working then I know I haven't overslept. I always feel like death after a nap, I feel worse for it but it gets me through the evening."
Eamonn added: "Yeah I know what you mean. My wife is very good, my wife comes to me and says, 'Are you sleeping? Are you sleeping?'
"And you wake up out of your skin and my answer usually... I can't even tell you my answer because we're on the air.
"But I just think why does it sap her enjoyment of life that I am sleeping 'again' as she always adds?
"Are you sleeping again?' Well, I'm not sleeping you've shouted in my ear am I?" he remarked as Isabel laughed: "Yeah that is cruel to wake someone up from a lovely nap."
Later in the show, Eamonn continued to berate his wife for waking him up while he naps.
He said: "We are also going to be talking to a sleep scientist who explains why a quick 40 winks could be very good for you. If you take 40 winks often, regularly your brain doesn't shrink. 'Are you sleeping?'"
Isabel teased: "I bet you I've got messages from Ruth if I check my phone, maybe she's sleeping catching up on her sleep."
Eamonn continued: "She never sleeps. Well actually that's a lie, she said last night she was going to bed early and she said, 'I am going to have difficulty sleeping.'
"She never has difficulty sleeping, she sleeps like a log but then she never stops during the day, I say to her to take a nap but no she would never do that."
