We know you love your favourite pillow, but it can’t stay in your life for too long. No, not even in the attic. According to a study, a third of a pillow’s weight after a period of one year consists of dead mites, their droppings, dust, dead skin cells and critters. Now, you really don’t want all that touching your skin. Why, you ask? Pimples, unhealthy skin and allergies. Not convinced? With continued use, pillows lose their shape and support.

Wash every 1-2 weeks

We sleep on our beds every day, and not all of us take a shower before bed. The result? All the dust, grime and dead cells that have built up in our hair and body throughout the day get transferred on to the bedding/bedsheet. Wash it every one-two weeks, but remember that washing pillows and bedding doesn’t actually kill the bacteria and microbes. You have to get new ones, eventually.

Do we need to explain this one? Alright. Germs are everywhere in the gym; machines, cabinets, walls, clothes, benches, changing rooms….you get the picture. It’s a very dirty, pathogen filled picture. If you’ve used your towel to wash the sweat off your body, you can use it on your face if you are in immediate need of pimples. Basically, wash it the second you get home.

Get a new case every three months, unless you like eye infections. We really hope you don’t like eye infections. A substance called biofilm is deposited by bacteria and other microorganisms; it basically hides the bacteria and lets them stay even when you wash the lens and case. Tip: Wash your lens case with hot water after every use.

Is this a surprise?! It was for some of our friends! If you use your loofah on a regular basis, then you definitely need to change it every two to three weeks. The dead cells and germs get logged in the loofah and can easily cause pimples all over the body with continued usage. Bonus: Drugstore brands of shower gels often have colourful loofahs with them! Treat yourself to a different shower gel every month.

Tip: Soak the cutting board in one part of full strength vinegar mixed in four parts water to purify the cutting board, or brighten with salt and remove odour with lemon.
