Davina McCall has compared self-isolating to living in the 'Big Brother' house.
The 52-year-old television presenter - who hosted the reality series on Channel 4 from 2000 to 2010 - has drawn comparisons between being stuck inside amid the pandemic to taking part in the social experiment.
After watching the housemates for 11 series, she picked up some useful tips for getting through the day indoors.
Speaking to The Sun newspaper, Davina explained: "I watched for years how people react to long periods in one place and it's fascinating seeing how it affects people.
"Most housemates started off incredibly positive and excited by the prospect of staying in one place for so long. But slowly, as the weeks went on, things changed. The first thing to go was always routine."
The 'Long Lost Family' star urged people to stick to their daily routine with regular meal times, dressing themselves in the morning and working out.
She said: "Anyone who used to watch the show will remember, in the early days, that housemates would lie in bed 'til 10am, then 11am, then noon. Bedtimes got later and later, which meant they totally lost track of time and normality.
"With this, meal times went out of the window. Instead of breakfast, lunch and dinner, they started grazing throughout the day. They stopped working out, making their beds in the morning, stopped bothering to put on nice clothes or do their make-up."
Without these simple practices, Davina noticed the 'Big Brother' housemates became more agitated with one another and resulted in some nasty arguments.
She continued: "It sounds silly but it was these little things that made a big difference to their moods. You could see it happening. Without proper meal times, without putting on a nice outfit, they started to lose that respect for themselves.
"They became more easily agitated. Things would annoy them, arguments would start and they would say things they'd never dream of saying to other people on the outside. We all watched those explosive arguments come out of nowhere. They lost respect for themselves and for those around them."
