The reasons for caution are ultimately about the safety of you and your baby. For example, spas generally won’t offer scrubs or wraps during pregnancy. This is for a few reasons. Firstly, skin is often more sensitive during pregnancy and scrubs can be too abrasive and uncomfortable. It’s also because some active ingredients that are common in treatments, such as lavender, are generally avoided during pregnancy because they can supposedly bring on labour. So it’s a precaution. However, plenty of spas use spa product lines that have specifically been approved for maternity spa treatments and offer dedicated prenatal therapies as a result.
