My question is, is it safe to use a waist training corset that is virtually able to shrink your waist? According to Womens Health, if you are wearing it everyday for long periods of time, it is most definitely not. In fact, according to health experts it doesn’t even really work, as it is more temporary than it is permanent. Therefore, if you take it off, your waist will eventually go back to its normal size. Also, in wearing it everyday it not only restricts your breathing but it also can do damage to your ribs over time. In a more in depth article, says waist training can cause acid reflux. This is because your waist and organs are so compressed, that the little food you are able to eat does not digest correctly; thus acid reflux being the result(i.e. heartburn or acid taste in throat). Also, it causes rib bruising, although most users confuse this as their bones shifting into a slimmer shape. Really they are just harming harming and bruising their ribs which sometimes can cause even more serious effects.
