Episode description

Your environment is rewiring your hormones, fertility, and long-term health without your consent. 

In this episode of The Human Upgrade, Dave Asprey sits down with Dr. Aly Cohen, board-certified rheumatologist, integrative medicine specialist, and environmental health educator. Together they expose how common toxins in plastics, pesticides, drinking water, personal care products, and food packaging are hijacking your biology. 

Dr. Cohen explains how daily chemical exposures contribute to autoimmune disease, thyroid dysfunction, hormone imbalance, infertility, obesity, cancer, and accelerated aging. You will learn how to identify hidden endocrine disruptors, spot surprising sources of microplastics and PFAS (“forever chemicals”), and apply science-backed detox strategies to protect your hormones, fertility, metabolism, and longevity. 



What You’ll Learn in This Episode: 

• How chemicals in household, cleaning, and beauty products disrupt hormones 

• The link between environmental toxins, autoimmune disease, thyroid issues, and infertility 

• Hidden sources of microplastics and PFAS chemicals and how to eliminate them 

• Affordable, practical steps to detox your home, water, and personal care routine 

• Dr. Cohen’s top biohacks to protect fertility, balance hormones, and build toxin resilience

Mindsip insights from this episode:

Choose reverse osmosis for cleaner drinking water at home

Tap water in the US is only required to be tested for 91 chemicals, while there are over 95,000 possible contaminants. Using a reverse osmosis filter at home is one of the best ways to clean your drinking water. When traveling, look for filtered filling stations or glass bottled water.

Test nutrient levels with blood tests for accurate health insights

Blood tests are the best way to know your nutrient levels, like vitamin D or iron. Symptoms like hair loss or fatigue can have many causes, so working with a knowledgeable practitioner and getting the right labs can save time and worry.

Choose simple cleaning solutions to avoid chemical overload

Most cleaning jobs can be done with soap, water, white vinegar, or lemon juice. Avoid bleach and chemical-heavy cleaners when possible, as they can disrupt hormones and immunity. Check labels for 'fragrance' and 'other ingredients'—less is usually healthier.

Build resilience through nutrition and healthy habits, not perfection

It's impossible to avoid every toxin, so focus on making your body more resilient through good nutrition, regular exercise, and healthy habits. Stressing over perfection can do more harm than good—balance changes with enjoying life.

Cook at home to reduce toxin exposure from restaurants

Most restaurants use unfiltered water and cook with non-stick pans or plastic containers, adding extra chemicals to your food. Cooking at home with safe ingredients and cookware gives you more control over what you eat.

Choose natural fibers to reduce microplastic exposure

Washing and drying fleece and other synthetic clothes releases microplastics into the water and air, which then end up in our bodies. Choosing natural fibers like wool and cotton for clothes and home goods can reduce this exposure.

Eliminate air fresheners to protect hormonal health

Air fresheners and scented products often contain chemicals that mess with hormones, especially testosterone. Removing them from your home and car is an easy way to protect your health (and everyone else's around you). Less is more when it comes to scents and cleaning.

Make impactful changes with small swaps at home

You don't have to be perfect—focus on high-impact changes at home, like switching to safer cleaning products, avoiding artificial fragrances, and using glass or stainless steel for food and drinks. Doing your best where you have control makes the biggest difference.

Clean up lifestyle and environment to reduce autoimmune disease risk

Autoimmune conditions are rising fast, affecting up to 14% of Americans. Many experts believe unregulated chemicals in our environment and products are a major reason, not just genetics. Cleaning up your lifestyle and environment can help lower your risk.

Optimize vitamin D levels for immunity and overall health

Most people are deficient in vitamin D, and standard 'normal' ranges may be too low for optimal health. Aim for blood levels of 60-90 (not just over 30), and test your levels rather than guessing how much to take. Vitamin D is crucial for immunity, heart, and brain health.

Implement Four A's to detoxify your life

To reduce your toxin load, follow the Four A's: Assess what chemicals are around you, Avoid and swap out harmful products, Add nutrients for better health, and Allow yourself to not be perfect. This practical approach helps you make step-by-step changes without feeling overwhelmed.

Minimize microplastics by choosing filtered water over bottled options

A single liter of bottled water can contain up to 240,000 microplastics, and up to 90% are nanoplastics. These tiny plastics are found not just in bottles but in many everyday items and can disrupt hormones and immunity. Opting for filtered water and minimizing plastic use can help lower exposure.
