Underwear without endocrine disruptors (100% cotton or wool)

A lot of underwear today is a synthetic fabric, even if it says it’s wool. Very often it’s actually a blend of wool and synthetic. So we went and found genuinely 100% wool or 100% cotton underwear.

Merino wool boxers made by Woolly brand100% Wool
Boxers from Jockey100% Cotton

My favorite is definitely the Wooly brand boxer briefs. The merino wool isn’t itchy or thick or anything like that. It feels great. I wasn’t able to find other 100% wool underwear that I wanted to get.

Why is synthetic underwear bad?

Synthetic materials like polyester are generally a form of plastic. That means they also produce tiny threads of polyester plastic that effect your body, called “microplastics.” Microplastics are known to be “endocrine disruptors,” meaning that they will lower testosterone. (source)

However wool and cotton are natural materials that have been worn for generations, and they won’t hurt your hormones. Natural materials don’t have microplastics.

Unusual experiments with synthetic underwear

One researcher made it his mission to figure out if there’s something wrong with synthetic underwear. He made underwear for dogs and lab rats and measured their testicular function after wearing it for months. It sounds crazy, but he claimed that the polyester material generated a type of static electricity that damaged the sperm count! Here is one of his studies: https://pubmed.ncbi.nlm.nih.gov/1456835/

Does wool underwear raise testosterone?

I don’t think wool raises testosterone, but it is a great material and feels comfortable. I think there’s a scientific case to be made that polyester underwear could lower testosterone however. But as far as I know there isn’t a study proving this in humans yet.

Our favorite moisturizer without endocrine disruptors

These moisturizers have no endocrine disruptor chemicals like phthalates or PFAS. There should be nothing but natural ingredients in your moisturizer. Of course, the best moisturizer is the one that you enjoy and get the best results from. You should like the smell and the feel of it, and it should work well for you.

Tallow, honey, and shea butter

We like moisturizers that are all natural. We don’t think there should be any ingredients that sound like a chemistry experiment, even if they are mostly safe. To really protect the hormones, we think it’s best to stay 100% natural. That’s why our top picks contain nothing but beef tallow, honey, shea butter, or essential oils. These are all natural products quite close to their natural state.

Xenoestrogens on my skin? No thank you!

The synthetic, commercial products you might see at the store contain a variety of weird chemicals. Many of the chemicals are endocrine disruptors, specifically they are artificially estrogenic, which is why some of them are also known as xenoestrogens.

Phthalates are common in most moisturizers since they have an ability to moisturize the skin.  But it is not worth it! Phthalates are xenoestrogens, meaning that they will increase risk of breast cancer and hormonal mood swings. Our recommendations are free of phthalates.

Should you really put tallow on skin?

Yes! Reviewers report great results when they use the tallow and honey balm. They say it feels great, with no icky mess at all. And they report seriously good results from the balm. Skin clears up, and dry skin goes away and stays away.

Use a moisturizer without endocrine disruptors for beautiful skin.

Tallow and honey both nourish the skin. They contain powerful natural compounds that your skin craves.

Tallow and honey together make the best moisturizer without endocrine disruptors

We like the tallow and honey balm best of all. There is absolutely nothing unnaturally hormone-damaging in it. It has no weird chemicals that might cause mysterious bad health effects. Tallow and honey are both near-superfoods full of healing and rejuvenating parts. Honey has been known for centuries to facilitate healing.

Shea butter is a good moisturizer for vegans

The shea butter product is good too – it’s got no xenoestrogens either. If you are looking for a vegan option, you should go with this one, since it comes from a tree.

Sunscreen without endocrine disruptors

It’s important to use sunscreen without endocrine disruptors. These sunscreen products are free of harmful chemicals like this. Endocrine disruptors are chemicals that damage your hormone levels. Endocrine disruptors are associated with breast cancer. Unfortunately, many sunscreens have these chemicals.

Physical sunscreen vs chemical sunscreen

There are two ways to block UV rays from damaging your skin. One is a chemical sunscreen – these are invisible on your skin. The other way is a physical sunscreen, which literally coats your skin so the sun is reflected off instead of reaching your skin. These are always a layer of visible color on top of your skin, because they have to physically block the sun’s rays. Unfortunately, there isn’t currently any chemical sunscreen without endocrine disruptors. They’re all physical sunscreens. Hopefully in the future someone will invent one, perhaps using certain promising herbal ingredients. (Like these)

Either the sun will burn you or you'll be exposed to chemicals if you don't use a sunscreen without endocrine disruptors!
The jolly sun will burn you, unfortunately, if you don’t take care!

Common endocrine disruptors in sunscreen to avoid

Oxybenzone (also known as Benzophenone-3), PABA, and homosalate are all common endocrine disruptors found in sunscreens, but not in the ones we listed. Since these chemicals have artificial estrogenic activity, they are called “xenoestrogens.” (source) Using sunscreen without xenoestrogens is imperative if you want to lower risk of breast cancer, or keep testosterone levels where they naturally should be. You should definitely use one of the xenoestrogen-free sunblocks listed here instead of a hormone-damaging one from the store.

What about olive oil or raspberry oil for sunscreen?

Unfortunately,  most of these simply don’t seem to work. They don’t really block the sun. Someone tried putting these on different patches of skin and found that the “natural” DIY sunscreens simply don’t protect the skin much at all. Link: https://nyponros.com/en/sunscreen/rasberryseed-oil-sunscreen

It seems that carrot oil may have some ability, based on this test: https://deeprootsathome.com/plant-based-sun-protection/

And raspberry oil may have some minor ability to block the sun as well.

Sunscreen that doesn’t lower testosterone

One of the big effects of endocrine disruptor chemicals like those found in some sunscreens is to lower testosterone. Since there is something of a low testosterone plague going on, probably due to the various chemicals in the environment, it is pretty important to be careful about only using a sunscreen without endocrine disruptors.

Other chemicals to avoid

We also want to avoid parabens and other strange chemicals in sunscreen. The ones we recommend are free of these things.

More things you can do to avoid sunburn

Simply staying out of the sun when your skin is vulnerable to sunburn is the best thing you can do. Always bring a coverup or have access to shade.

Only get as much sun as your skin can handle. While it’s true that the sun is good for you, it is still very bad for you to get sunburned. It is radiation damaging your skin and you don’t want this!

Apparently, Vitamin C, avoiding seed oils in your diet, and Vitamin E will all help you be a bit more sunburn resistant, but you shouldn’t rely on this at all.

Timing your sun exposure to avoid sunburn

If you get sun before 10am and after 4pm (or pre 11am & post 5pm during daylight savings time) then the sun doesn’t really contain as much UV light that burns you. You can get lots and lots of this sunlight and experience the healthy effects of bright and red wavelength light on you, without worrying so much about being burnt. Then you can get maybe 15 minutes of full body UV sunlight during the middle of the day to get your Vitamin D.

Laundry detergent without endocrine disruptors

Unfortunately, most detergents are full of estrogenic chemicals. These synthetic chemicals damage your body and your hormones. It’s important for both men and women to use a laundry detergent without endocrine disruptors. These are our best recommendations. There’s more detailed info below.

Why it’s so important to get laundry detergents without endocrine disruptors

The detergent residue gets into the clothes, and this absorbs through the skin. Skin absorption is very potent!

“Xenoestrogens absorbed by the skin are ten times more potent than those taken orally, because they travel directly to the tissues instead of passing through the liver” and “Many household cleaners contain xenoestrogens. Particularly dangerous are laundry detergents and fabric softeners, because residues on clothing, towels, and other items are worn against the skin. (source)

Endocrine disruptors found in other laundry detergents

We researched our list above to make sure it only contains laundry detergents that have no xenoestrogens or any of the endocrine disruptor chemicals below. Here are some of the anti-testosterone or estrogenic chemicals that can be found in other laundry detergents.

Phthalates – Just as bad as you thought

Phthalates are potent endocrine disruptors. They are anti-androgenic (so they likely lower testosterone), and they mess up the thyroid as well. (Source)

Phthalates include DEHP, DiNP, DBP, DiBP, BBP, DPP, DnHP, and DnOP. If you want a laundry detergent without phthalates, you need to get one with none of these. Our recommendations are free from all these phtalates.

Phenols, including BPA

These three chemicals are all phenols, a type of chemical that is often in laundry detergents.

  • BPA
  • TBBPA
  • Nonylphenol

Phenols are xenoestrogens. That means that these synthetic chemicals will have artificial estrogenic effects in the body, which causes all kinds of trouble. In men, one danger of this is low testosterone. In women, another danger is breast cancer. (Source)

The laundry detergents above have no BPA, nonylphenol, or other phenols. So don’t worry!

PFAS in laundry detergents

PFAS can be found in laundry detergents. Two common PFAS are the following:

  • PFOA
  • PFOS

These PFAS are not in the laundry detergents we have listed.

D4 (last but not least!)

D4, or Octamethylcyclotetrasiloxane, is a chemical that can be found in laundry detergent, but not in the ones we like!
