We've all been there: you've hurried out of the house for the day, when suddenly you feel a stab of worry that in your rush you forgot to switch off an appliance.
Pretty soon, those thoughts start to spiral from 'did I leave the oven on?' or 'are my straighteners switched off?' to 'has the house burned down to the ground?'
That nagging feeling isn't a pleasant thing - but luckily, there's an easy life hack that will stop you fretting in no time.
The super easy solution was shared by Lifehacker in relation to going away on holiday - but it's ideal for anyone who starts worrying that they've left an appliance switched on at home, whatever the circumstances.
All you need to do is take a quick snap of the gadget in question - whether it's the thermostat, your straighteners, or the stovetop - before you head out, so that you can later reassure yourself that you switched everything off.
Simple enough, right?
All you need to do is add the photo hack to your pre-holiday to-do list, or build it into your daily routine.
Just the thought of having those snaps on our phone is making us feel all kinds of reassured.
This doesn't only apply to gadgets, either. You can use the hack for anything in your house.
Want to know that you shut the back door, closed the loft window or shut the garage door?
This crafty trick works for all of the above and should provide a catch-all solution that prevents you from fretting when you're away from home.
Europe travel expert Sunil Metcalfe for Black Tomato recommends the photo trick, too.
Speaking to Reader's Digest, he said: "Similar to forwarding your emails to your colleague or leaving your pet in the care of someone you trust, taking a picture of the locked back door, the closed garage door or unplugged appliance, allows you peace of mind to let go and be fully present.
He continued: "We've all had that gut-wrenching moment en route to the airport where you think you've made a critical error in preparing for your trip. Having a picture eliminates this moment of panic.
"But taking a picture is a much more cost-effective option and leaves no room for technological error," he adds.
Of course, remembering to take the snaps in the first place is half the battle - we might have to set an alarm on our phones or leave a well-positioned post-it note to help us with that one.
