In the previous part, we explored how food, food packaging, plastics, and drinking water can contribute to everyday exposure to endocrine-disrupting chemicals (EDCs). In this article, we’ll move beyond the kitchen and examine another important area of daily life—our homes and the products we use on our bodies.

The average person uses dozens of consumer products every day. Shampoo, soap, toothpaste, moisturizer, sunscreen, deodorant, makeup, laundry detergent, household cleaners, furniture, electronics, and even the dust in our homes can all contribute to our overall environmental exposure.

This doesn’t mean these products are unsafe. Most are regulated and considered safe when used as intended. However, scientists continue to study whether long-term, repeated exposure to certain ingredients may influence hormonal health, particularly during sensitive life stages such as pregnancy and early childhood.

Understanding where these exposures come from can help us make thoughtful choices without creating unnecessary worry.

Cosmetics and Personal Care Products

Many people begin and end each day using a variety of personal care products.

These may include:

• shampoo

• conditioner

• body wash

• soap

• lotion

• deodorant

• sunscreen

• makeup

• perfume

• hair styling products

Although the amount of any single ingredient in these products is usually small, researchers are interested in the fact that many of them are used repeatedly over many years.

The skin is an effective protective barrier, but some substances applied to the skin can be absorbed to varying degrees, depending on the ingredient and the part of the body where it is applied.

Scientists continue to investigate which ingredients are most relevant for long-term hormonal health.

Fragrances

One word that often appears on cosmetic labels is simply “fragrance” or “parfum.”

Rather than referring to one specific ingredient, this term may represent a mixture of many different chemicals that create a product’s scent.

Some fragrance formulations have historically contained certain phthalates, which help fragrances last longer.

Today, many manufacturers have reduced or eliminated specific phthalates because of changing regulations and consumer demand, although practices vary among companies and countries.

For individuals with sensitive skin or fragrance sensitivities, fragrance-free products may also reduce skin irritation and headaches.

Preservatives

Cosmetics and personal care products need preservatives to prevent the growth of bacteria, yeast, and mold.

Without preservatives, many products would become unsafe long before they were used up.

One group of preservatives that has received considerable attention is parabens.

Laboratory studies have shown that parabens can interact with estrogen receptors, although they are much weaker than natural estrogen.

Human studies have investigated possible links between paraben exposure and reproductive or hormonal health, but the evidence remains mixed, and scientists continue to study whether the low levels found in consumer products have meaningful health effects.

Many companies now offer paraben-free products, giving consumers additional choices.

UV Filters in Sunscreen

Some chemical UV filters used in sunscreens have also been studied for possible endocrine activity.

At first glance, this may sound concerning.

However, it’s important to keep the bigger picture in mind.

The health benefits of protecting your skin from excessive ultraviolet (UV) radiation—including reducing the risk of skin cancer and premature skin aging—are well established.

Current evidence does not support avoiding sunscreen because of concerns about endocrine disruption.

Instead, if you wish to minimize exposure to certain chemical filters, mineral sunscreens containing zinc oxide or titanium dioxide are available and provide effective sun protection when used correctly.

The most important message is simple: protect your skin from excessive sun exposure.

Household Cleaning Products

Our homes contain a wide variety of cleaning products designed to remove dirt, grease, bacteria, and mold.

These products improve hygiene and help prevent infectious diseases.

Some cleaning products also contain ingredients that researchers are studying for possible endocrine activity or other health effects, including certain solvents, fragrances, and surfactants.

For most people, the greatest concern with cleaning products is not endocrine disruption but respiratory or skin irritation caused by improper use.

Following label instructions, ensuring good ventilation, and avoiding unnecessary mixing of cleaning products remain the most important safety practices.

Air Fresheners and Scented Products

Many homes contain products designed to create pleasant scents.

These include:

• air fresheners

• scented candles

• essential oil diffusers

• incense

• fragrance sprays

Some scented products release volatile organic compounds (VOCs) into the air.

Certain fragrance ingredients have also been investigated for possible endocrine activity.

Research is ongoing, and the health effects vary depending on the specific product, ingredients, ventilation, and frequency of use.

If you enjoy scented products, using them in well-ventilated spaces and in moderation is a practical approach.

Some people also choose fragrance-free alternatives, particularly if they have asthma, allergies, or chemical sensitivities.

Indoor Air Quality

Many people spend approximately 90% of their time indoors.

As a result, indoor air quality can play an important role in overall health.

Indoor air may contain:

• cooking fumes

• tobacco smoke

• dust

• mold spores

• volatile organic compounds

• chemicals slowly released from furniture, flooring, paints, and electronics

Most of these exposures are not unique to endocrine disruptors, but together they contribute to the overall environment in which we live.

Fortunately, improving indoor air quality is often simple.

Opening windows when outdoor air quality is good, using kitchen exhaust fans while cooking, maintaining heating and ventilation systems, and avoiding indoor smoking can all make a meaningful difference.

Household Dust

Dust is more than just tiny particles of dirt.

It can contain fibers, skin cells, pollen, soil, pet dander, and small amounts of chemicals released from household products over time.

Researchers have found that household dust may contain:

• phthalates

• flame retardants

• PFAS

• pesticides brought indoors on shoes

• heavy metals from outdoor pollution

Young children are particularly exposed because they spend more time playing on the floor and frequently place their hands in their mouths.

Regular cleaning helps reduce dust accumulation and improves overall indoor hygiene.

Simple habits include:

• vacuuming regularly

• damp dusting surfaces

• removing shoes before entering the home if practical

• washing hands before meals

These habits have benefits beyond reducing exposure to environmental chemicals.

Furniture and Building Materials

Many modern homes contain materials that slowly release small amounts of chemicals into the indoor environment.

Examples include:

• upholstered furniture

• carpets

• vinyl flooring

• composite wood products

• paints

• adhesives

New furniture or freshly renovated rooms sometimes have a noticeable smell.

This is often due to the release of volatile organic compounds, a process known as off-gassing.

The strongest emissions generally occur when products are new and decrease over time.

Good ventilation during and after renovations helps improve indoor air quality.

Electronics

Computers, televisions, mobile phones, printers, and other electronic devices contain a variety of materials designed to improve durability and fire safety.

Some older electronics contained brominated flame retardants that have since been restricted or replaced in many countries.

As electronics age, tiny amounts of these substances may accumulate in household dust.

Regular cleaning and proper recycling of electronic waste help reduce environmental contamination.

Children’s Products

Infants and young children are often more sensitive to environmental exposures because their organs and hormonal systems are still developing.

For this reason, many countries have introduced stricter regulations for products intended for children.

Examples include restrictions on:

• BPA in baby bottles

• certain phthalates in toys

• lead in paints

• specific flame retardants

These regulations have significantly reduced exposure to several chemicals of concern.

Parents can further reduce unnecessary exposure by following age recommendations for toys, replacing damaged products, and maintaining good household hygiene.

Do Natural Products Always Mean Safer?

Many products are marketed as “natural,” “green,” or “chemical-free.”

While these labels may appeal to consumers, they do not always reflect scientific evidence.

Everything around us—including plants, water, and air—is made of chemicals.

Some natural substances are extremely safe.

Others can cause allergies or even be toxic.

Likewise, many synthetic ingredients have undergone extensive safety testing.

Rather than assuming that natural is always better, it is more helpful to evaluate products based on their ingredients, intended use, and available scientific evidence.

Small Changes Can Make a Difference

There is no need to replace every product in your home overnight.

If you would like to reduce unnecessary exposure, consider making gradual changes such as:

• choosing fragrance-free products if you have sensitive skin

• selecting cosmetics with shorter ingredient lists when practical

• ventilating your home regularly

• dusting and vacuuming frequently

• using cleaning products according to their instructions

• avoiding unnecessary use of heavily scented products

• replacing products gradually as they wear out instead of discarding everything at once

These small habits are realistic, affordable, and easier to maintain over time.

The Bottom Line

Our homes and personal care routines contribute to everyday environmental exposures, but they also provide many benefits for comfort, hygiene, and quality of life.

Current research suggests that reducing unnecessary exposure where practical is a reasonable approach, particularly during pregnancy and early childhood.

However, there is no need to fear every cosmetic, cleaning product, or piece of furniture.

Instead, focus on informed choices, good household habits, and maintaining perspective.

Environmental health is about reducing avoidable risks—not achieving a perfectly “chemical-free” home.
