A study looking into the most common behaviours undertaken by Australians when no one else is at home revealed most people engage in private activities they are not always proud of.

Walking around naked, eating junk food and stalking ex-partners on social media are some of the most popular activities for Aussies to do when home alone.

A study looking into the most common behaviours undertaken by Australians when no one else is at home revealed most people engage in some level of private activity.

The most common activity was enjoying a daytime nap, with nine in 10 respondents polled in a survey commissioned by Victory-Blinds.com.au claiming they did it when they had the house all to themselves.

Others used the time to catch up on guilty pleasure reality TV shows or started talking to themselves.

Victory-Blinds spokesman Stuart Clark said spending time at the house alone was a common way for people to recharge.

“Every person, no matter how outwardly social they may seem to others, needs some time alone to themselves every now and again to partake in a little ‘me-time’,” he said.
