Ever picked up a time-saving ‘life hack' from an online video? Today might be a good day to start because a new study suggests that those little tips and tricks save people almost four hours of effort every week.

That's according to a survey of 2,002 Americans, 41% of whom have described life hacks to be useful efficiency shortcuts.

One-quarter of those familiar with life hacks even claim having six hours per week to spare after using the shortcuts.

Conducted by OnePoll on behalf of Minute Rice, the survey also found that the most popular life hacks were those focused around cooking or the kitchen, with 54% saying they use them regularly.

Cooking hacks that ranked high included batch cooking meals for the whole week (41%), boiling potatoes with skins on for easier removal (40%) and using microwaveable rice (39%).

Six in 10 respondents say they watch life hack videos on the internet, with 42% of people saying they've shared their own life hack tips online at some point.

Like all skills, some life hacks require practice; respondents revealed that it takes them an average of three attempts to get a life hack right.

33% have learned tips for make-up, 33% have organized their kitchen better, and another third have found tips to make gardening more enjoyable.

"Anything that gives us time back in our day, from cooking hacks to back-to-school hacks should be embraced. Because when we save time on daily life tasks, we can slow down and enjoy time with those who matter most," said Erica Larson, Senior Brand Manager of Minute Rice.
