Pregnancy
Heat therapy devices are likely safe to use during pregnancy, but well-controlled clinical studies in pregnant women are lacking.
If you are pregnant or may become pregnant, talk to your doctor before you start heat therapy.
Breastfeeding
It is not known if or how heat therapy may affect breastfed infants or milk production. Therefore, if you are breastfeeding or plan to breastfeed, talk to your doctor before you start heat therapy.
