Plastic containers

Tupperware, Gladware, Snapware, you name it – everyone has a collection of plastic containers. They’re great for storing leftovers, but studies show these can contain high levels of bisphenol-A (BPA), a toxin frequently found in plastics. Even in low doses, it can have a significant impact on hormonal balance and the brain. Make sure to never use plastic containers in the microwave unless they are labelled microwave safe. Try using glass or stainless steel containers instead.
Fabric sprays

While they might protect your couches and chairs from stains, many of these sprays contain questionable chemicals that can contaminate the air in your house. The National Consumer Affairs Centre of Japan found fluorine resin in four of seven major spray brands. The size of the particles was enough that inhaling the spray would pose a significant health risk.

Old contact lens case

If you’re neglecting the case you store your contacts in, you’re risking an eye infection according to optometrist Reecha Kampani, OD. She advises throwing out your solution daily and replacing the lens case once every three months. Using a case for too long can add to pathogen build-up, leading to potential scarring and vision loss.
