The Difference Between Adolescence & Puberty & Why Early Puberty is Not Good For Children

Adolescence is not the same as puberty, so let's clear that up right away. Adolescence is a ten to twelve year period when your children start becoming more independent of their parents. It starts in late grade school or early junior high and lasts till they are in their twenties. Puberty lasts for about one to three years and it's a process by which your hormones change you into a mature sexual being. Girls usually go through puberty about a year before boys. But not anymore. It's happening far earlier, whereas nine years old isn't so odd anymore.

Early puberty is incredibly problematic for families because there is a trend of young girls developing at nine years old based on environmental hazard exposures in utero, childhood, and adolescence. And when girls go through early puberty, they are more likely to suffer from mental health problems. There are also other links to higher pregnancy rates, higher high school drop out rates, and lower test scores. Early maturers are also more likely to report psychosomatic symptoms such as abdominal pain, sleep disturbances, headache, upset stomach, breathlessness, tremors, and heart palpitations. They are also more likely to suffer from eating disorders, anxiety, panic attacks, & depression.

Chemicals Linked to Early Puberty in Girls

There are chemicals in commerce that are linked with early puberty in girls inside personal care products, so if you are pregnant or have young children, pay attention. These chemicals include phthalates, bisphenols, triclosan & parabens.
  • Phthalates are found in scented products like perfumes, soaps, and shampoo and will be hidden as "fragrance" or "perfume" instead of their real name
  • Bisphenols are found in packaging and containers that leach into products and may or may not be labeled as #7 plastic
  • Triclosan is found in toothpaste & mouthwash and will always be labeled
  • Parabens are used as a preservative in personal care products and will always be labeled
You may have noticed that some of these chemicals are not on the label and that is part of the problem. When it comes to phthalates and bisphenols, you may never know they are there.

Phthalates are typically added to synthetic fragrances to keep the odor around longer and is an endocrine-disrupting chemical. But because of lobbying efforts, they are not labeled on the bottle. The only way to tell is by looking for the word "fragrance." Fragrance is a legal loophole that has the ability to contain thousands of ingredients covered up by one word. Companies have been arguing for years that it protects them from having others copy their formulations. But in a world where labs can now reverse engineer ingredients, that's no longer the case. No one is protected from a competitor stealing their formulations, so why do we still have this law? Will this ever be changed? We hope so! But until then, avoid anything with the word "fragrance."


Bisphenols are found in plastic packaging and containers and is an endocrine-disrupting chemical. There is no federal mandate telling companies to disclose them being next to or adjacent to the ingredients. Bispenols have the ability to leach out of the container into your personal care products when they are in contact with heat, fat or acid, which is commonplace in the production and formulations of personal care products. What this really means is the personal care industry needs to start paying attention to what type of plastic they are using and avoid #7 with bisphenols.

Triclosan is a bioaccumulating antibacterial chemical & environmentally persistent endocrine disruptor, meaning it's designed to kill bacteria & absorbs at a faster rate than it's excreted from an organism. That's part of the reason the FDA banned the use of triclosan in hand soap. The chemical was previously in antibacterial soaps, but the FDA found that there was no benefit in using anti-bacterial soap over regular soap and water. When it comes to triclosan, pay close attention to your toothpaste because some of the most popular brands, like Crest, have them.

Parabens are harsh preservatives and endocrine-disrupting chemicals that mimic estrogen in the body. They are used in things like shampoos, conditioners, lotions, facial cleansers, shower gels, and scrubs, as well as cosmetics, feminine care wipes, and feminine washes. Parabens discourage the growth of microbes so they are found in things that contain water or aloe vera.

Study Linking Personal Care Chemicals to Early Puberty

Researchers followed 338 children from birth till they were in adolescence to ascertain whether certain chemicals linked to early puberty were problematic. Most of these women were latina and below the federal poverty line. They tested the mother's urine for the contaminants during pregnancy in order to understand how much of these chemicals they were consuming. They also interviewed the women on lifestyle decision they were making that would lead to contamination. They then followed up with the children when they turned 9 years old and examined the girls for puberty development every 9 months until they were 13 years old.
  • Over 90% of the kids' urine samples showed concentrations of ALL hormone-disrupting chemicals, except for triclosan.
  • 73% of the pregnant women's urine samples contained concentrations of triclosan
  • 69% of urine samples from the kids contained concentrations of triclosan
They found that for every doubling of the mother's urine concentration of triclosan, the girls started menstruating at least one month earlier. Then for every doubling of phthalates in mother's urine, their daughters developed pubic hair about 1.3 months earlier. And half of the girls in the study started growing pubic hair at 9.2 years old and then started menstruating at just 10.3 years old.

As expected, boys puberty timing wasn't impacted at all because these chemicals impact estrogen and not testosterone. The study was funded by the National Institute of Environmental Health Sciences and the US Environmental Protection Agency.
