Finally Sleep Deep: How to Choose a Supportive and Non-Toxic Mattress – What to know when you have Mast Cell Activation Syndrome, Histamine Intolerance, or Ehlers Danlos (EDS) Hypermobility

If you’re dealing with Mast Cell Activation Syndrome or Histamine Intolerance, you may find it difficult to get good quality sleep.

Insomnia is extremely common in Mast Cell Activation Syndrome.
About 80% of clients at Mast Cell 360 have sleep problems.

This could be due to a brain that is on high alert. Or maybe you experience sweats at night. Maybe you wake up because of neck, shoulder, and back pain.

I had all of these issues. For years, I dreaded bedtime. I would just end up tossing and turning for 3-4 hours.

And when I could sleep, it wasn’t deep sleep.

There were several things that added to me not being able to sleep. Like my injuries. I’ve had a lot of back, neck, and spine injuries in my life.

I was kicked in the head by a horse when I was 9. It fractured 2 vertebrae and badly broke my tailbone and damaged my upper neck.

Then, I was in a car accident at age 16. My neck and back were more damaged.

Then, in 2017 I was t-boned by someone who didn’t look before he came racing out of a driveway.

I was still dealing with the lasting impact of my old injuries plus Ehlers Danlos (EDS) hypermobility. Then the 2017 accident gave me a concussion that took 6 months to heal.

And it had a devastating effect on my body.

I couldn’t lie down for more than 45 minutes at a time. No matter how I laid down or how I turned, I was in pain. And it was so bad, I couldn’t sleep.

After watching me go downhill for 9 months, my own functional doctor said:

“Look, Beth, you can’t heal without sleeping. And if you don’t get some sleep now, you’re never going to heal. This is just going to keep spiraling out of control.”

That’s when I realized I had to change some things. In a big way. I needed to sleep! But why is sleep so important?

We’ll talk about that next.

Sleep and Mast Cell Activation Disorder and Histamine Intolerance

Sleep is so important for healing. That’s when the normal functions slow down. You’re not using energy to digest food. You’re not taking in information from around you. It’s quiet, your eyes are closed, and everything is still.

Your 5 senses (sight, hearing, smell, taste, and touch) get to have a break. And all that energy is now available for growth and repair.

There is no substitute for restorative sleep. And it’s 10x more important when you’re dealing with Mast Cell Activation Syndrome.

But let’s say you’re not sleeping well. There’s a downward spiral that happens with lack of sleep when you have Mast Cell Activation Syndrome.

When mast cells are overactive, they produce a lot of inflammatory mediators. Like histamine.

Histamine gets dumped into the bloodstream in the middle of the night. This histamine dump often causes those with Mast Cell Activation Syndrome to wake between 2am and 4am.

In fact, anything that triggers Mast Cell Activation Syndrome (like chemical and mold toxins) worsens sleep.

And not getting quality sleep worsens Mast Cell Activation Syndrome.

It becomes a downward spiral of poor sleep, worse mast cell activation, worsened sleep…and so on.

If you have Mast Cell Activation Syndrome and sleep issues,  you know that downward spiral. Especially if you also have any chronic pain that wakes you up.

Deep, restorative, sleep is absolutely key to healing when you have Mast Cell Activation Syndrome.

One of the most important considerations for restorative sleep is your mattress – the place you rest your body each night.

I was really surprised when I learned that the right mattress can help you get up to 80% more deep sleep each night!

I tried a few different mattresses after that last car accident. I was hoping that would help me sleep better. But none of them helped.

They were off-gassing chemicals and that made my Mast Cell Activation Syndrome even worse! And that worsened my sleep.

And the organic, non-toxic ones were causing more pain because they weren’t supportive enough. This also worsened my sleep., I had to look for yet another solution. And while I was looking, I learned something important.

I learned that, unfortunately, mainstream mattresses might actually be working against your body’s need for restorative sleep and better health.

There are 2 major things that seriously impact your body’s ability to deeply heal when you have Mast Cell Activation Syndrome:

  • Poor sleep
  • Toxicity (chemicals and mold)

First let’s look at toxicity. Toxins can trigger mast cells. And yes! your mattress might be adding to your toxic load! Let’s look at how.

Toxins Hiding in Mattresses – What to Know When You Have Mast Cell Activation Syndrome or Histamine Intolerance

You’d think mattresses would be designed to be non-toxic. After all, you spend 1/3 of your life with your face against them. You breathe in whatever smells or toxins they give off….all night long.

Unfortunately, most mattress manufacturers aren’t concerned with avoiding chemicals in the final product.

A greater focus is actually making sure they aren’t likely to catch on fire. And so flame retardants are added.

And a mattress needs to be comfortable, right? So manufacturers add materials to boost comfort. The problem with that is that not much attention is given to whether those materials put chemicals into the air — chemicals like Volatile Organic Compounds (VOCs).

VOCs are definitely something you don’t want. Especially if you have Mast Cell Activation Syndrome or Histamine Intolerance. Read more about VOCs and other “toxic triggers” of Mast Cell Activation Syndrome and Histamine Intolerance here.

But the flame retardants are probably some of the most toxic. Let’s start with an overview of those toxins…and some of the health problems they may cause or make worse.


  • Firemaster 550 – Firemaster 550 was shown to be an endocrine disruptor.
  • Formaldehyde – May worsen autoimmune disease. Shrinks the thyroid, causing decreased T3 and T4 thyroid hormones. Also linked to cancer. Maybe contribute to Type 2 Diabetes.
  • Chlorinated tris (TDCPP) – May cause hormone problems. May increase risk for some cancers.
  • Boric Acid – May cause hormone issues.
  • Antimony trioxide – May cause nausea, vomiting, weakness, muscle pain, lung problems. Even cancer. And it’s really bad for the cardiovascular system. May cause arrhythmias and damage to the heart.
  • Vinylidene Chloride – Symptoms may resemble alcohol intoxication, including convulsions and spasms. May cause you to pass out. May cause problems with the liver, kidneys, lungs, and nervous system.

Fire retardants are found in a number of different mattresses. Now let’s look at other chemical toxins found in specific types of mattresses…and the health risks that may be associated with them.


  • 2-chloro-1,3-butadiene (Chloroprene) – Symptoms may include sleep issues, fatigue, immune system problems, liver problems, and hair loss. May increase your risk of cancer.
  • Diphenyl diisocyanate (Also in natural latex) – May promote inflammation and immune system problems. Linked to asthma and breathing problems.


  • Formaldehyde – May worsen autoimmune disease. Shrinks the thyroid, causing decreased T3 and T4 thyroid hormones. Also linked to cancer. Maybe contribute to Type 2 Diabetes.
  • Methylenedianiline – May injure the liver or thyroid.
  • Methyl Chloride/chloromethane – May cause issues with the nervous system. Including dizziness, blurred vision, tremors, confusion and convulsions. May cause nausea or vomiting. May also affect the heart, liver, and kidneys.
  • Isocyanate compounds (benzene, acetone, ethylene oxide) – May promote inflammation. And immune system problems. Linked to asthma and breathing problems.
  • Naphthalene – Can cause autoimmune problems. May raise your stress and cortisol levels. May cause thyroid problems. (Also found in mothballs).

And the other mattresses aren’t off the hook. Companies may switch out chemicals. While some chemicals have been discontinued, others have been added.

So, are you safe if you get a mattress that says it’s “All-Natural” or “Green”? Not necessarily.

I’ll cover the practice of “greenwashing” in the next section. 

“Greenwashing” – What to know When You Have Mast Cell Activation Syndrome or Histamine Intolerance

“Greenwashing” is what happens when an industry makes a product seem healthier than it is. It might be marketed as organic, natural, safe, or environmentally friendly.

The thing is, no testing is required to make the claims. And generally, no certification is needed, either.

Words or phrases used in marketing may include:

  • Organic
  • Natural
  • Green-energy
  • Eco-friendly
  • Made from recycled materials
  • Made using wind energy
  • Lower carbon footprint
  • Sustainable
  • Carbon neutral

And the list goes on. When companies say things on packaging or their website, it’s important to note what they DON’T say.

For example, a mattress may be made using green energy. But it could still contain toxic materials.

In other words, these claims are for the purpose of selling the product. You’d need to do some research to find out if the product (including a mattress) is actually healthy. Healthy for the environment and your body.

So, how do you sift through the false claims? How do you choose a truly healthy mattress?

First, let’s start by looking at the pros and cons of common mattresses. 

I really want you to know what to look for when buying a mattress. When you have significant Mast Cell Activation Syndrome like I’ve had, you can’t afford to not sleep well.

And if you aren’t mattress shopping yet, you’ll be prepared when you are.

Types of Mattresses on the Market – What to Know When You Have Mast Cell Activation Syndrome or Histamine Intolerance

If you’re searching for a new mattress, you may be feeling overwhelmed by the options. There are traditional spring mattresses, latex mattresses, memory foam mattresses, gel mattresses…the list goes on.

So, in this section, I’ll give you a basic description of each. And then give some pros and cons…including which ones could have toxic chemicals that can trigger worsening of Mast Cell Activation Syndrome. Let’s start with traditional spring mattresses…


This is the kind of mattress your grandparents likely had. They have been used since the 1930s. They have multiple metal springs which provide an underlying support layer. They tend to be on the firm side.


  • affordable
  • widely available
  • comfortable for many people


  • tend to sag over time
  • not long-lasting
  • can be noisy – especially the old ones!
  • does not prevent transfer of movement – every time your partner rolls over, you’ll know it
  • Springs that are interconnected can pick up very high EMF levels, especially if the room has reverse polar


Natural latex actually is natural. It’s made from latex from rubber trees. Natural latex mattress brands include Avocado and Saatva. There are two types of latex foam. Dunlop latex is dense and heavy. Talalay latex is softer and lighter. The difference is in how the sap is processed.


  • a natural and hypoallergenic option
  • latex contains naturally-occuring anti-bacterial and antifungal compounds
  • they “sleep cool”
  • good at preventing motion transfer (good for couples and light sleepers)


  • not as supportive of the spine, hips, and shoulders
  • being natural, they break down faster
  • may last only 4 or 5 years before needing to be replaced
  • depending on manufacturing, some may have toxic VOCs added to the natural latex
  • tend to be heavy and difficult to move

Also: These may not be a good idea if you have a latex allergy. Some are hypoallergenic. But you may not want to find out the hard way. Synthetic latex may be better in that case…


Latex comes from the rubber tree. During World War II, there was a rubber shortage. In fact, it was called the World War II Rubber Crisis. Synthetic latex mattresses were originally made because of this shortage. The use of synthetic latex for mattresses has continued.


  • like natural latex, these mattresses “sleep cool”
  • provides pressure point relief for comfort
  • good at preventing motion transfer
  • don’t tend to cause issues if you have a latex allergy
  • usually less expensive than natural latex


  • a lot of chemicals are used in the manufacturing of synthetic latex mattresses (these will off-gas while you sleep)
  • not as long-lasting as natural latex mattresses
  • tend to be heavy and difficult to move


You’ve probably heard of Tempur-Pedic. It’s the most popular brand of memory foam mattresses. The material it’s made of is called “viscoelastic.” It was originally made by NASA to protect air travelers in case of a crash.

Memory viscoelastic foam is made of polyurethane…with added chemicals to make it viscoelastic.


  • comfortable + supportive
  • memory foam conforms to your body
  • evenly distributes your weight
  • great a preventing motion transfer


  • lots of added chemicals that off-gas into the air you breath
  • not durable: materials break down over time causing these types of mattresses to lose firmness
  • holds heat so it promotes nighttime sweating


This is an example of “greenwashing.” There’s nothing natural about it. Example brands include Keetsa and Loom & Leaf (Saatva). It’s still a type of petroleum oil product that off-gasses toxic chemicals.


  • comfortable + supportive
  • conforms to your body
  • evenly distributes your weight
  • prevents the transfer of motion


  • contains toxic chemicals
  • may support the spine, hips, and shoulders but depends on the inner core of the mattress


Gel foam is a viscoelastic foam like memory foam. What’s different is that it’s infused with beads of gel. The gel beads are there to help with air movement inside the mattress. That means it will sleep cooler.


  • soft and comfortable
  • supportive of the spine
  • prevents motion transfer
  • unlike memory foam, they sleep cool


  • made of polyurethane with chemical additives for flexibility (chemical off-gassing through the night)
  • the addition of gel makes them more expensive than regular memory foam
  • when the gel breaks down, the mattress won’t be as firm.


Gel Matrix™ is made of one hundred percent pure and safe, food-grade mineral oil. That’s the same thing baby oil is made of. This gel is made into a flexible, elastic material. It looks like a honeycomb. The honeycomb stretches and bends to support the body. So, it’s really comfortable.


  • supportive of the spine, hips, and shoulders
  • durable: doesn’t break down from heat, moisture, pressure, or oxygen
  • non-toxic
  • doesn’t off-gas – you can breathe without worry!
  • hypoallergenic
  • antimicrobial


  • because it’s made of mineral oil it can’t be labeled as organic, but mineral oil doesn’t off-gas, which is good!.
  • more expensive at first, but lasts longer.

You can see from some of the “cons” listed above that you have to watch out for some of those toxins we talked about earlier.

So, what if you have an organic mattress without all those toxins? If it’s working for you…GREAT!

If you have no body pains and aches…if you are able to sleep deep and sound…if you don’t feel hot and sweaty…there isn’t any reason to change if it’s non-toxic.

However, you may find that the organic mattress loses support. If you start hurting at some point, then you would want to re-evaluate what your next mattress should be. You might consider giving the Organix Bed a try.

What if you have a Tempur-Pedic or other memory foam mattress?

You might have purchased one of these to help with chronic pain. I had one too! And it definitely helped my fibromyalgia pain and hot spots.  But this is a tough one to decide…

Unlike an organic/latex mattress, these foam mattresses are full of toxins like flame retardants and formaldehyde.

These are well-known to be cancer causing. So, if you are dealing with mast cell issues, you want to keep your toxin load down as much as possible.

We’ve also been asked: “What if the memory foam mattress is two years old and has off-gassed by now. Is it still toxic?”

Well, there is another issue with air mattresses and memory foam mattresses.

They can grow mold.

And this mold and other chemicals in mattresses were shown as far back as 1994 by Dr. Sprott to be a major link in SIDS (Sudden Infant Death Syndrome)

This means there can potentially be a big ongoing problem in these mattresses. And it’s not just during the initial 2 year off-gassing period.

Everyone has to decide for themselves. But, it’s something to think about.

If you are thinking about purchasing a new mattress now or in the future, let’s look at what you want to know…

How to Choose a Healthy Mattress – What to Know When You Have Mast Cell Activation Syndrome or Histamine Intolerance

If you have Mast Cell Activation Syndrome or Histamine Intolerance, you want to make sure you’re getting a mattress that will promote health and healing. And doesn’t make your mast cells worse.

11-point Mattress Safety and
Quality Checklist

You can use this to check out any mattress you’re looking at:
Does this mattress offer…

  • Non-toxic, hypoallergenic material with zero off-gassing
    • This is especially important for those of us with Mast Cell Activation Syndrome or Histamine Intolerance. Toxins can set off mast cells leading to inflammation and awful symptoms.
  • Excellent postural body-support
    • Many people with chronic back pain get relief from the right mattress. Having a mattress which provides excellent postural support (back, hip, shoulders) is important for getting a good night’s sleep.
  • Temperature control (sleep cool, not hot)
    • Memory foam mattresses can cause you to get too hot at night causing night sweats. That’s not helpful for getting restorative sleep.
  • Technology to reduce tossing and turning for a deeper sleep
    • Proper body support will keep you from shifting around. Even when you have small discomforts, you’ll turn over to relieve the ache. You may not even notice you are doing it, but it can interrupt your sleep cycle. And if you have chronic pain, poor support won’t let you get comfortable at all.
  • Firm and soft at the same time
    • A firm mattress offers postural support for your back. A soft mattress can take the pressure off of shoulders and hips. Ideally, your mattress will have both.
  • Responsive customer support
    • “What happens if…?” You want to be able to get support for anything that comes up. And any questions you might have.
  • 15-20 year, comprehensive warranty
    • If you’re investing in a mattress, you want to make sure it’s going to last.
  • At least 60 day return policy, no questions asked
    • “Try before you buy” – What if you invest in a mattress and find it’s too hard? Or too soft? You need to be able to try the mattress before committing to it long term. We all have different preferences.
  • Tested durability
    • Materials in some mattresses can break down by heat, moisture, oxygen or pressure. This means they won’t last as long.
  • Available financing options
    • A good mattress is both an investment in your health as well as a financial investment. Financing options can help you invest in a quality mattress without needing all the funds up front.
  • Great value
    • Is it worth the price? What if you spend a lot of money but then have to replace the mattress in 6 years? Was it worth the lower cost?

After trying a number of different types of mattresses, I finally found one of the best, most comfortable, non-toxic mattresses on the market. 

The mattress I picked is the Organix Bed™ by Intellibed®.

It’s made of a posture-supporting Gel Matrix™. The matrix is able to stretch, bend, and spring back. So, it’s really comfortable. And can help reduce pain and nighttime awakenings. It lets you get a good night’s sleep.

You can spend at least $1500 on a mattress every 5-7 years.

Or you can buy 1 mattress designed and warrantied to last 20 years. This costs a few thousand less in the long run.

This is important to me because I don’t want to change mattresses every 5 to 7 years. That was hard on my body.

This is why I love that the Organix Bed™ mattress is durable – and has a warranty for up to 20 years.

It’s also non-toxic. And doesn’t off-gas. When I got mine, I didn’t have to air it out at all. That’s a big deal for me!

Usually new things have to air out for 2-3 weeks before I can use it. But with my Organix Bed™, I didn’t have to worry about that at all.

You can sleep and breathe deeply. Without worrying about what you’re being exposed to.

I’m definitely sleeping better.

I am noticing huge improvements with my chemical and mold detox, too! Remember the two things that most affected my body’s inability to heal? Poor sleep and toxicity.

I feel better since I’ve been getting deeper sleep. And I’m not exposed to toxic chemicals coming from my mattress any more.

I’m also super excited that my back doesn’t hurt in the morning.

A mattress is a big purchase. And I don’t want you to go through what I went through by making the wrong mattress choice. And I especially don’t want a toxic or non-supportive mattress to affect your health when you have Mast Cell Activation Syndrome.

As you can imagine, it can take a long time to figure all this information out on your own. It was even overwhelming for me, and I love to do research.

Luckily, I was able to reach out to my friend Jason Payne who is also an industry mattress expert.

Jason has worked in the mattress field for many years. He knows all the pros and cons of various mattresses…including which ones are non-toxic and offer good support.

Jason really saved me a lot of headaches (and poor sleep).

He helped me sort through what I needed to know about choosing a mattress. 


I also learned a lot of really helpful, new information about getting good sleep.

Jason wanted me to know what to look for and what to avoid. And to make sure I made the right choice for me. Jason answered a ton of questions for me.

I had a hard time navigating the mattress world. So I thought, if I did, then you might have a hard time navigating it on your own too.

This is why I thought you might like some solid information on getting a good night’s sleep. And good info on how to choose a non-toxic, supportive mattress.

So I asked Jason if he would help our Mast Cell 360 community by putting together a webinar with me going over what he taught me last fall.

And I was so happy Jason said he would!

This is the free webinar we made for you called How to Choose a Healthy Mattress:

===>Free “How to Choose a Healthy Mattress” webinar with Beth O’Hara and Jason Payne 

This webinar will talk about what you need to know about mattresses. And how to make a good decision for yourself.

No, you don’t need to buy anything, at all. And, even if you don’t need a new mattress…you can still learn a lot about getting good sleep!

Plus, when you do need a mattress, you’ll have what you need to know so you can make a good choice for yourself.

Now, I also really like transparency. So I want to let you know Jason’s background. Like I said before, Jason does work in the mattress industry.

But, what I really like about Jason is that he’s a good guy who just wanted me to make the decision that was right for me.

Plus, he’s a no pressure kind of guy. Jason just wants people to get a good night’s sleep. And to get the mattress for them, whichever it is.

So, just get the info you need. And then get the mattress that is right for you.

We’re going to talk about lots of info on getting a good night’s sleep.

I’m pretty educated about sleep. And I still learned a lot from Jason. I think you’ll learn several new things, too.

Here’s how you can join us:

===>Free “How to Choose a Healthy Mattress” webinar with Beth O’Hara and Jason Payne 

Jason also said he’d be happy to answer any questions you might have about mattresses. He can help you make the best decision for you (no pressure).

You can reach him here with any questions you have about choosing the right mattress (no pressure, just to get the help you need in answering your questions and making the right choice for you):

And if you decide to get an Organix Bed, you can save a lot if you mention the Mast Cell 360 community offer.

Here’s more information on that:

And they do also offer financing, which can help a lot too.

Here Was What Made My Final Decision…

I was replacing my mattress every 5-7 years. That cost me about $6600 over 20 years, plus taxes and delivery/shipping.

But, the Organix Bed is warrantied to last 20 years. And with the 10% off, the free delivery, free mattress protector, and free sheets….the effective cost over 20 years was nearly 1/2 the cost of what I was paying over time for the other mattresses.

And they have a 90 day trial period. So, I was able to try it without worry I might be wasting money on yet another mattress that wouldn’t work.

But I’ve had my mattress now since the fall and I’ve been sleeping great!

    Have you ever tried The Green Mattress or Avocado Mattress? Thoughts on them? I’ve been looking at those, and I was curious.

    1. Suz, Mast Cell 360 Team

      Hi Katie,
      I don’t know if Beth has specifically owned those mattresses, but I do know that she looked into A LOT of different mattresses and the companies that manufactured them before deciding on the one she recommends in the post. This is the one she felt hit all the marks.
