More on Endocrine Disruption

Our endocrine system is the main hormone regulator in our body and endocrine disruptors are chemicals that throw it out of whack. Chemicals like BPA and phthalates are infiltrating our lives at an ever increasing rate.[1] [2]

Considering that hormones from our pituitary, hypothalamus, and other glands around our body control everything from metabolism to sleep, protecting it from disruption should be a top priority.

Plastics are the main source for endocrine disruptors but they’re not the only culprits.

Paper receipts, money, tin cans, and electronics are all common, everyday products that contain endocrine disruptors.

Take a look at a few ways endocrine disruptors are destroying our health.

1. Endocrine Disruptors Harm Reproductive Health
Endocrine disruptors are commonly found in personal items, medicines, and cleaning products. Believed to be especially harmful to male reproductive health, these chemicals are linked to testicular cancer, male infertility, and even genital deformities. That same sunscreen you use for protection from the sun’s harmful rays might be one of the sources of disruptors that could be causing some unexpected issues.[3][4] A recent study found a chemical in sunblock has been linked to infertility in men, and another noted that phthalates in toys cause many of the same issues.[5] It’s not just men who are at risk from endocrine disruptors. Evidence shows women are also in danger, and can even have a shorter reproductive lifespan.[6][7]

2. Endocrine Disruptors Cause Hormonal Imbalance
While BPA is a known endocrine disruptor, a recent study showed that BPA-free plastics might be just as bad. Some BPA-free resins have been found to contain estrogen-like compounds.[8] These resins are used in plastic production and substituted for BPA. Keep your eyes open for phthalates and parabens, too, two endocrine disruptors commonly found in personal hygiene products that are known to cause hormonal imbalances.[9] [14]

3. Endocrine Disruptors Lower a Child’s IQ
Perchlorate is an endocrine disruptor found in rocket fuel, fertilizers, and fireworks. It’s even been found in 4 percent of large US water supplies – mainly those near military bases or defense compounds. A recent study suggested that prenatal exposure could affect a child’s IQ. [10] This isn’t the first time the finger has been pointed at perchlorate. Perchlorate exposure is known to affect thyroid function in women by stopping the necessary transport of iodine–perhaps this is how the lower IQ happens. [11]
