Should You Sleep in A Waist Trainer? No! Here’s Why.

During the first few days of getting used to wearing your brand-new waist trainer, you will be building up your tolerance and length of time for wearing it. Starting with 1-2 hours and gradually working your way up to 10 hours (or more) per day, you’re sure to start feeling like a modern-day celebrity or an old-school debutante in no time. Whether it’s medical, purely superficial, or somewhere in between, staying on trend with a waist trainer is easy and accessible.

But what happens once you successfully make it through your first week or so and want to speed up your results or maximize that hourglass shape? Should you sleep in a waist trainer? Sure, you technically CAN sleep in a waist trainer, but no, you definitely shouldn’t. If you are thinking about trying it, there are a few factors that you should consider first.

Here’s Why You Might

I get it, sleeping in a waist trainer might actually seem like the best option in some cases – you don’t have to deal with the discomfort throughout the day, and all the work is done while you’re asleep. It sounds like a win-win. There may also be some other factors in your life that would make sleeping in it easier than wearing it throughout the day.

  • Your lifestyle doesn’t fit it – Just because you want the hourglass figure, doesn’t mean you have a lifestyle that allows you to be perched like a Victorian-era fashion model all day and there is a serious shortage of fainting couches in the world today. If your day-to-day activities make corset wearing difficult or impossible, it could seem like night time is your best bet.
  • Your work won’t allow it – For those with particularly active jobs, such as fitness instructors, cleaners, or any other labor-intensive career, wearing a waist trainer all day will not only be uncomfortable, it’s also not very practical. Additionally, those who wear uniforms for work may find it challenging to include an entire corset under that uniform.
  • Your clothing style can’t cover it – Despite many waist trainers being designed to fit seamlessly under your clothing, there are sure to be some outfits out there that just won’t blend with a corset. If your personal style prevents a waist trainer from being worn easily, it will look a bit strange under your backless dress for 10 hours a day.
  • You want pinup status – For many dedicated waist training experts, 10 hours a day just isn’t long enough. There are some women out there who wear theirs for up to 20 hours per day (on occasion). If you only have 16 waking hours in a day, you have to find those extra hours somewhere.

Here’s Why You Shouldn’t Sleep in A Waist Trainer

We all know the phrase “No pain, no gain,” and we’d be remiss to try to discourage anyone from boosting their self-confidence and slimming the inches around their waist. However, when it comes to fashion trends, it’s important not to do more damage than necessary in order to gain your celebrity body. Before you decide to sleep in a waist trainer, have a look at the health implications from wearing one in general.

Organ constriction. It goes without saying that any amount of pressure from a corset will constrict and cause your organs to shift. While a temporary shift isn’t the worst thing you could possibly do to your body, doing so while you sleep can lead to breathing problems due to your diaphragm being unable to expand, and can cause unnecessary pain to the other organs. If you ever have difficulty breathing, you should remove your waist trainer immediately.

Acid reflux. Many women report experiencing acid reflux when sleeping in a waist trainer, which occurs when acid from the stomach re-enters the esophagus, thanks to the increased pressure pushing it back. This can be uncomfortable and can lead to pain, such as heartburn, and will undoubtedly affect your sleep.

Excessive sweating. Depending on the material, time of year, and your body, the constriction of the cincher won’t just affect your organs; it can also lead to more sweat than you are used to by limiting the airflow to your torso. Sweating too much will not only disrupt your sleep cycle, but it will also add to the wear and tear of your waist trainer (see below). And if damaging your waist trainer isn’t bad enough, sweating can also lead to folliculitis, an inflammation of hair follicles due to friction or sweating. Rare? Probably. Worth the risk? Probably not.

Your body needs a break. Some of the main reasons why we sleep at all are to give our body the chance to recover from injury, regenerate cells, heal, and rest. If your body needs to take a break from things that are actually good for you, something as simple as drinking water, it only makes sense that it would also need a break from excessive pressure. If you are wearing the waist trainer during the day, this break is especially important.

Added wear to your shapewear. Sleeping in your corset will add more use to the product. The sweat, dust, oils, and general grime that are transferred while you sleep can shorten the lifespan. Your trainer will also be subject to more friction as you roll around your bed throughout the night.

Here’s Why You Can

Many brands of waist trainers will concede that it is entirely possible to sleep in your waist trainer if you absolutely feel that you must. However, most will also note that it isn’t necessary. If you are wearing the cincher for 10 hours a day, adding on the extra 7-8 hours while you sleep isn’t beneficial for the average person, and is quite uncomfortable for most people.

Despite the fact that it isn’t necessary, there are still some wearers who sleep with them on and don’t report any problems. You may be one of the ones who doesn’t find it uncomfortable, in which case it’s doable and not strictly forbidden.

If you do decide to try it, there are a few things you should include in your sleep routine. First, you should look into a cincher that will make sleeping slightly easier. Invest in a waist trainer that is loose or made with a lighter material, such as cotton or mesh blend, that will give you a little more breathability while you sleep. Some trainers are made shorter in length which will provide you with more room to move without your entire torso being constricted. The best option for a waist trainer that you can wear to bed is the YIANNA Short Torso Waist Trainer (link to best price on Amazon), which is both shorter in length and sports a breathable construction.

Next, you should consider how you sleep. Regardless of your sleep position, you need to ensure that your spine is being supported and kept in alignment. In addition to having a firm mattress for support, consider your use of pillows:

  • Side sleepers – place a pillow under your waist in the gap that is created by your shapewear between your ribcage and the bed. It may also help to put one between your knees for more comfort.
  • Back sleepers – place a pillow between your lower back and the mattress. You may also want to use a thinner pad under your head. This will help to avoid too much elevation and prevent your ribs from crunching.
  • Stomach sleepersWe don’t actually recommend sleeping on your stomach in general, but if you must, try sleeping without a pillow under your head to prevent additional strain on your neck and spine and a softer mattress.

Lastly, begin the process with a nap before going for the full night. As part of your waist training journey, it’s never recommended to jump straight into eight hours of sleep without adjusting your body to it. Try taking a nap first to see how your body feels and if you notice any of the side effects listed above. Like your first few days of wear, you will want to gradually build yourself up to learning how to sleep with your waist trainer on.

A great alternative to waist trainers in general are body wraps – which can achieve results faster without having to rely on wearing a waist trainer as often. I personally recommend Brazilian Detox Clay Body Wraps (link to Amazon) which have consistently worked better than my waist trainer in a shorter period of time!

Here’s What You Should Keep in Mind

Sleeping in a waist trainer may increase the progression of your waist cinching at the moment, but regardless of how long you wear it, as soon as you stop wearing it consistently, you will begin to regain your body’s natural shape. Waist trainers are not a permanent solution for weight loss or the exaggerated hourglass shape, no matter how many hours you strut around (or sleep) with it on, or how many pictures you post to the ‘gram.

At the end of the day, the fundamental purpose for sleeping in a waist trainer is ultimately about achieving maximum results, but a better way to do that is with proper dieting, exercise, and taking care of yourself. Rather than going straight to sleep with it, try building a consistent and healthy routine while incorporating (instead of relying on) your waist trainer.
