Our sweat glands play an important role to cool down our bodies and regulate our temperature.  Absent or nonfunctioning sweat glands are one of the key symptoms of ectodermal dysplasias. If you don’t sweat, you may experience health issues if prolonged overheating occurs and the body isn’t cooled. This can be serious for you, your child, or anyone that has ectodermal dysplasia if not prevented or treated.

If you are searching for ways to manage hypohidrosis, look no further! Today, we will explain why individuals with some types of ectodermal dysplasias don’t sweat and suggestions for how you can successfully manage it in your daily life.

What exactly is hypohidrosis?

A typical person not affected by an ectodermal dysplasia is born with approximately 2-4 million sweat glands. People born with some types of ectodermal dysplasia may be born with few sweat glands and the ones they have may not work normally. They don’t sweat normally. This condition is called hypohidrosis.

In our new library article about sweat glands and ectodermal dysplasias, pediatric dermatologist, Dr. Elaine Siegfried, explains that with less sweat glands, individuals with ectodermal dysplasia do not produce enough sweat to cool off their bodies, for “sweat production is controlled by the nervous system, in response to increased body temperature.”

There is a common misconception about hypohidrosis within ectodermal dysplasias, as people often think that the inability to sweat is only found in hypohidrotic ectodermal dysplasia (HED). Hypohidrosis is also present in ankyloblepharon-ectodermal defects-cleft lip and/or palate (AEC) syndrome, ectrodactyly-ectodermal dysplasia-clefting (EEC) syndrome and other types.

Read Dr. Siegfried’s article to understand how hypohidrosis can be easily mixed up with its opposite, hyperhidrosis, which is excessive sweating and how it differs from anhidrosis.

Signs of Overheating If You Don’t Sweat

Our body temperature fluctuates throughout the day depending on our activities. If it is not regulated, it is all too easy to overheat. Significant overheating is called hyperthermia which could lead to serious medical consequences such as heat exhaustion, heat strokes, and possibly death. While those conditions are possible, taking preventive measures and using common sense will make them unlikely.

It is imperative to catch the signs of overheating early on to avoid health concerns. These signs typical consist of:

  • Fevers
  • A flushed face
  • Red ears
  • Lethargic movements
  • Labored breathing

Your child will likely get crabby when they are hot so look out for that! Kids typically don’t want to end their playtime, even if their bodies begin to feel hotter than normal. So it is important to teach them that if they feel too warm, they must alert their parents or take action to cool themselves down in the ways they were taught.

If your affected child is a baby, you may not want to bundle in blankets as it they may overheat. Newborns should not be put under warming lights if jaundiced.

If you have little children who don’t sweat, urge teach them how to recognize if their body is heating up more than it should. Some parents teach their kids to say phrases such as “I’m getting warm” or “can I go somewhere cool?” whenever they are getting too uncomfortable. You will also find that children often instinctively seek the shade or cool areas to cool down.

How to Stay Cool

Our Cooling Guide is a great resource to learn more about hypohidrosis and to find cooling tips.  Some of the best advice come from our families who have the most experience. They share with one another what they have learned in our different Facebook groups. Here are some things families said they use the most to keep cool:

  • Cooling mattress pads – These mattresses have built on cooling technology to help regulate your body temperature during the night.
  • Temperature monitor – This will allow you to pinpoint your child’s temperature easily. 
  • Cooling vests – These vests can be helpful for hot summer days or in situations where you may not have access to as much water. They even come in toddler sizes. They can be worn over your clothes to keep you feeling cool for hours. There are lots of companies offering a variety of different options. (add pic?)
  • Cooling caps – Your head and upper body are prone to heating up quickly, and these caps will help you regulate your body temperature.
  • Spray bottles – Not only are these fun to play around with, a quick spray is perfect for when you need a whiff of cool water. They are inexpensive and easy to carry with you at all time.
  • Misting fans – You get the best of both worlds with this device – air flow and water!
  • Wet your child’s shirt before going outside. Rewet as the shirt dries.
  • Warm showers – Make sure that the shower is warm and not cold. A cold shower will shock their body. But, a warm shower will allow their body temperature to return to normal at a steady rate.
  • Tint windows of your car to help prevent the sun from warming them in the back seat.
  • Install an auto starter for your car. On warm days, start the car with the air conditioning blasting for several minutes to cool it down before getting in.
  • Lots and lots of water – This tip cannot be stressed enough! Drink it. Wear it.

Tips and Tricks When You Don’t Sweat

Rebecca Sylvester talks about her greatest struggle to keep her sons cool.

“My brother had HED growing up, so we had a game plan. I also have two sons with it. The greatest struggle would be when you get into a situation where you don’t know an easy way out to get cool, like on public transportation.

Or if there’s a long walk outside, and when we participate in summer sports. We plan what we do based on the weather. During school, my kids carry a camelback and wet their shirts. We love to stay at the lake during the summer.”

One of Rebecca’s sons, Joseph, has HED. He loves to ski in the snow!

For NFED mom, Rebekah Parish, planning ahead helps her son Mason stay cool day to day. Mason is affected by HED.

“Awareness, preparation, and monitoring. We gauge our activities around the temperature and humidity levels when planning our day. My son, Mason, loves it outside, so we try and work around the higher temperatures to maximize that play time.

As temperatures increase, we continue to monitor him, moving him to shaded activities, adding his vest, a hat, or a cooling hat to extend his play.  Most of his play areas have been set up in the shaded areas around our house. We schedule naps, indoor play, learning activities, library time, etc. during the hottest times of the day.”

Advice from Adults Who Don’t Sweat

Coping with hypohydrosis does get easier as your child gets older. They learn how to handle their condition without constant guidance from their parents. They will be able to use their independence to guide others through the same journey, just like 29-year-old Kevin Kronvall, who has AEC syndrome. He gives fantastic advice as talks about his journey with hyperhidrosis from when he was young, to today.

“It’s important to not let nature dictate how you choose to live your life though. Being outside and active were important to me, but you also have to understand, there are certain things that you may have to do to be able to enjoy it and adjust. The biggest struggle was remembering to hydrate and making sure I had adequate protection from the sun like a hat, sunscreen, wearing a rash guard style t-shirt or long sleeve. Finding the balance of being outside too long was tough.”

Kevin’s hypohidrosis has made him more aware of his actions and how to handle his condition.

“I think the biggest thing is the shift in accountability. When I was young, it was more on my parents to remind me to put on sunscreen or to wear a hat outside. As you grow older and become more mature, you build those proactive behaviors. You also start to understand the reasons why you take extra precautions. You always remember the times vividly when you didn’t put on the sunscreen-it burned for a few days- so better listen to mom now!”

Kevin is a big proponent of staying active and refusing to let your condition prevent you from engaging in outdoor activities.

Kevin does not allow his hypohidrosis to dictate his life. Here he is running a marathon!

“I think the biggest thing parents can do is to get their kids involved in as many activities as possible, whether it be sports, theatre, etc. When you’re playing sports, you have to get creative. I played a lot of soccer growing up. I would get water and sunscreen at halftime or during a slow possession in play or ask to be subbed out since the inability to sweat would tire me out sometimes. As you grow older, you can kind of feel it in your skin when your body is starting to heat up a bit-kind of similar when you noticed you have eaten too much at a dinner and feel bloated.” (add pic of marathon run)

A key takeaway that Kevin provided is a truth that the NFED encourages all families to explore.

“The more involved the child is, the more confident they will become and embrace dealing with different situations and being able to overcome challenges such as not being able to sweat.”

We agree with Kevin. Kids who don’t sweat should not let their condition stop them from having fun. Teaching your child to figure out ways to do the activities they love will go a long way in helping them to be on teams, pursue sports and learn about themselves. Providing them with the tools to do that and safely is key.  Virginia Higgins shared how she managed staying cool while exercising in her story, “I Have AEC, and I Can Run.”

      My sister’s son got a high fever since 1 months and my sister stated he doesn’t sweat. Is it symptoms of ED? Does Ed effect on growing and learning ? Your reply would be very informative for me. I am so worrying right now.

    3. 8
      Veronica Minard on July 29, 2022

      Hi Sabita, while not sweating and high temperatures are symptoms of ectodermal dysplasias, a doctor really needs to make that diagnosis. I would recommend reading more about the symptoms on our website and accessing our documents that can be shared with doctors about the syndromes. Here are some links for you:

      Symptoms Overview: https://www.nfed.org/learn/symptoms/

    Hello, my problem is my burning feet. Most of the time my feet get warm at night, which interrupt my sleep. The room temperature is 60 degrees, I use a very thin blanket (in the winter), I can’t even tolerate the sheets on the bed. recently even my legs and the upper body gets warm and I don’t sweat. The burning feet interrupt my sleep which leaves me tired during the day. Any suggestions.

      Hello. We recommend that you review information on cooling tips at https://www.nfed.org/treat/medical-treatment-options/. Perhaps, you could try pointing a small fan at the end of your bed and perhaps sleeping with your feet outside of the covers. The cool gel patches might help keep your feet cool. Best wishes as you find a cooling tip that works for you.

    I have a daughter who is constantly hot but doesn’t sweat. She plays a lot of sports and last spring almost had a bad heat stroke during a game. Luckily, i caught on to her strange demeanor on the field and pulled her out of the game. I’ve brought this matter up to her pediatritan but she sort of brushed it off and said she was fine. Who can I go to to get her tested?

It has stopped me from stepping outside even in the winter

      Hi, Cameron! Have you been diagnosed with an ectodermal dysplasia? Unfortunately, I am not a medical professional so don’t have the expertise to answer your question directly, but we highly recommend reaching out to your doctor to explore what might be causing this.

      If you’d like help finding a doctor in your area that might have experience treating individuals with ectodermal dysplasias, please contact us at info@nfed.org, and we can see if we know of anyone in your area!

      Thanks for reaching out, and I hope you can get some assistance soon!

      Veronica Minard on May 3, 2022

      Hi, Diana: I am so sorry to hear about your son! Is he also affected by Ectodermal Dysplasias? Our advice is really tailored for individuals with that specific diagnosis, and most of our cooling advice has to do with using water directly on the skin or cooling vests, and I am not sure that would be safe for your son, with his burns. My best advice would be to contact your doctor to get advice, as they know his history and direct needs. Best wishes to you – Veronica

    AJ on April 23, 2022

    Hello,
    Im a female in my 40s and I dont sweat during the day. I will overheat easily and quickly when outside in warm weather. I am sensitive to cold too. So I use ice packs on my groin to cool down my blood. I do wake up drenched though. Almost every night and we keep our house cool. Im not on meds and only am on the cusp for thyroid, but sugar always reads fine. Not sure what is going on, but its been this way for a long time.

    1. 30
      Veronica Minard on May 3, 2022

      Hi, AJ – it is so hard to say why you aren’t sweating. If it is associated with an ectodermal dysplasia, you would most likely have other symptoms, which you can review here: https://www.nfed.org/learn/symptoms/. Of course, all of our information is associated with that diagnosis. I would recommend talking it through with your doctor to see if exploring and ectodermal dysplasia diagnosis makes sense for you. Unfortunately, there are no cures for ectodermal dysplasias, but we do have a lot of advice and treatment information on our site. Best of luck to you! – Veronica

    Hi , i use to run and exercise no problem. I was in a major car accident, occipital dislocation, and now I don’t sweat. I w
    Can only ride my bike if it’s under 80°. This is the worst as I live in Texas so hot! I went for a walk and had to stop after a mile with heat exhaustion. It’s really scary, I had water but that’s not enough. I stopped at a model home and laid on the floor for in the air conditioning for an hour before I could make it home.

    Is it possible to build up a tolerance to the heat?

      Veronica Minard on June 6, 2022

      Hi, Suz. Because everyone’s situation is different, and I am not a medical professional, I don’t have the expertise to answer your question accurately. I would highly recommend discussing this with your doctors. We do offer resources on how to stay cool, if that is helpful: https://www.nfed.org/learn/library/stay-cool-cant-sweat/ and https://www.nfed.org/wp-content/uploads/2016/06/Cooling-Guide.pdf.
