Binding is a great way to reduce chest dysphoria and become more comfortable with your body. For many, a flat chest affirms identity or helps with identity presentation. The most important thing is to remember that binding is not required for your gender and gender expression to be valid. If you choose to practice binding please ensure that you do so safely.
A FEW PRO-TIPS
Never bind for more than 8 hours a day. Binding for long periods of time, especially if you're binding regularly, will break down tissue and can cause a variety of medical issues.
Never sleep in or work out in your binder.
Never use products like duct tape or ace-bandaging to bind your chest. These sorts of materials will restrict your ability to breathe and move properly.
