Phthalates are synthetic chemicals used in the production of many different types of plastics. These plastics can be found in everything from kids’ toys and lunchboxes to shower curtains, air fresheners, and perfumes, according to data from the Canadian Cancer Society.
Many health experts have expressed concern about phthalates because they’re suspected to lower testosterone and metabolism levels, making people feel fatigued and low on energy. Fatigue can promote muscle loss, prevent physical activity, and result in weight gain. That’s why many medical experts recommend avoiding plastics with the number 3 identification code and purchasing 100 percent natural fragrances.
