There are many different kinds of form-fitting and form-flattering clothing that women like to wear to bed each night. Whether it's a tight tank top, a pair of booty shorts, or a sexy spandex negligee, many women head for bed sporting very tight, taut, and clingy attire. And while you (and quite possibly your partner) may enjoy the look and feel of these items, you're actually engaging in a different kind of risky bedroom behavior every time you wear them. In fact, your skin-tight nighties are posing a risk to your overall health. First, when you wear constricting clothing to bed, such as pants with an elastic waistband or a binding type of shirt, you're negatively impacting your circulation as well as hampering your ability to breathe normally throughout the night. And speaking of breathing, it's your skin that also needs to breathe, and wearing taut and tight items each night can lead to skin irritations and even infections. But if that's not enough to sweat over, wearing binding clothing also has been linked to inhibiting the development of melatonin, which is a key hormone that helps to regulate your sleep cycles. And when your body's natural circadian rhythm is off, the prospect of getting a good night's sleep is off as well. From now on, it's important to remember that your desire to "sleep tight" is just not right.
