Sleeping with waist trainer

A waist trainer, or also known as a corset, was first used in the late 1500s to the early 1600s. Women during this time are doing their best to have a smaller waist. Because back then, women were considered beautiful if they had a smaller waist.

But not everyone was able to survive this kind of fashion trend. It is because of the material used and the hassle in wearing them. It takes two people to set up a waist trainer or a corset on one woman.

Nowadays, waist trainers are made to be comfortable and at the same time functional. And it can be worn by the owner by herself. It needs a little bit of effort though, but it is better than having two people struggling in wearing the waist trainer for you. Waist trainers can help make every woman feel comfortable while they are trying to achieve that hourglass body.

Sleeping with a waist trainer can be a challenge. But modern waist trainers are made to be flexible so that you can still move however you want. It will also allow your skin to breathe and move freely without any pain.

But if you are still having a hard time sleeping with a waist trainer on, below are some tips for you to follow and sleep comfortably with a waist trainer on.

Must be the right fit

What is the point of wearing a waist trainer if it is not your size? There are a lot of women who tend to go for a size smaller than theirs. This is not advisable because waist trainers are made to slowly train your body to have an hourglass figure. It takes a few weeks or a few months for your body to be able to get used to the figure you are trying to get.

It is also not advisable to get a waist trainer that is too loose. It defeats the purpose of a waist trainer and it will not be able to get the results that you always wanted. If you are planning to get a waist trainer, have it fit by a professional so that you will not. Sizes will depend on the material being used.

There are some waist trainers that run largely because of the tightness of the material. And there are waist trainers that run small because the material is not as tight as the others.

You must be able to breathe with your waist trainer

Waist trainers are understandably tight. But it doesn’t mean that you are not allowed to breathe with your waist trainer. Modern waist trainers are tight but it can still allow you to breathe comfortably wherever and whenever you are wearing it. And the right size really does matter. If you want to sleep with a waist trainer, you should be able to breathe normally to avoid future complications.

Break in your waist trainer before wearing them regularly

Just like new shoes, we need to wear them around the house so that we will be able to get the feels of it. It will also give your shoes a chance to mold according to the shape of your feet. The same goes for waist trainers. Not everyone has the same kind of body size and type. If you have a brand new waist trainer. Wear it for at least 3 to 5 hours a day before wearing them for longer hours. Especially if you are going to sleep with them.

Know your comfortable sleeping position

All of us have our preferred sleeping position. We get to sleep peacefully and comfortably according to the position we want to be in. And if you are planning to wear a corset while sleeping, your position will matter.

Sleeping Position Matters

Back Sleepers

“If you normally sleep on your back, when wearing a waist trainer you may find that your pelvis and hips can sag down, particularly if your mattress isn’t very supportive or dips in the middle. The key to making your sleep experience more comfortable is to support the curve in your lumbar area, in the lower back.

Use small pillows or rolled up towels beneath the small of your back as well as under your knees. This will take the pressure off your back and help distribute your body’s weight more evenly.” – hourglassangel.com

*Additional tip: Use a small pillow on your head area. This is to avoid misalignment of your spine and trachea. It will also allow you to breathe comfortably*

Side Sleepers

Sleeping on your sides while wearing a waist trainer may be a challenge. Because you will need to find your balance, you need to engage your core, and you need more pillow support to avoid rolling over. What you will need is a body pillow. Women who went through pregnancy will give you a guaranteed review that a body pillow is one of the most comfortable pillows that you will ever have. There are two types of body pillows: U-shaped pillow and the long rectangular pillow. It supports your entire body and keeps it in the position that you want to sleep on.

Tummy Sleepers

If you prefer to sleep on your tummy, there are some things that you need to know about it. First is that sleeping on your tummy is not advisable. But if you are really comfortable with it, you better use the latex kind of waist trainer, according to hourglassangle.com.

Because if you are going to use the ones with the steel bone, it might hurt you due to the bones poking on your skin. Second is to try sleeping without a pillow. This is to keep the alignment of your spine and as well as prevent more stress on the back of your neck and your lower back.

If you can’t sleep without a pillow, try using a pillow topper. It is thin and still can make you feel as if you still have a real pillow; but thinner.

Consider the surface tension of your mattress and the cushioning of your pillow

Before you even buy yourself a waist trainer, you should also know how firm or soft your mattress is. Because the mattress will be the one that is going to support your body when you are going to sleep with your corset on.

And for your pillows, there are different shapes and sizes for you to choose from. It is for you to find the right one to support your entire body while you are sleeping with your waist trainer on.

Expect some issues during your first few nights with a waist trainer on

If you are new to wearing a waist trainer, expect that there are few discomforts during the first few nights. Your body is still adjusting to the way the waist trainer works. And it molds your body into the shape that you wanted.

But do not expect that you will get the 100% that you really wanted. Because it will always depend on your body type. And not everyone has a naturally wide set of hips. At least with a waist trainer, it will help you emphasize your female features bit by bit.

It takes a little bit of sacrifice in order for us to achieve the body that we desire. Discipline has a huge role when it comes to this kind of situation. We need to work harder to be able to reach what we want.

And when it comes to our body, we need to watch over the food that we eat and keep a physically active and healthy lifestyle. For women, waist trainers can help in speeding up the results that we want. We can sleep with our waist trainers on because it is the only time that our body is relaxed.
