UV-A and UV-B Rays

Very Low Risk

Safe. Compatible. Minimal risk for breastfeeding and infant.

Ultraviolet rays (UV) type A and B are a part of sunlight radiation.
Some lamps also emit this type of radiation for cosmetic purposes (tanning bed device) and treatment of certain skin diseases: psoriasis, vitiligo, etc. and, because of their germicidal properties for disinfection and sterilization of instruments.

UV-A and UV-B rays may cause premature aging of the skin and the risk of skin cancer (melanoma) is increased in people with frequent exposure without adequate protection. But excessive use of sunscreen creams in pregnant women, mothers and infants causes a deficit of vitamin D both in the plasma and breastmilk that warrants the use of oral supplementation with vitamin D to breastfed infants for prevention of rickets and other possible health issues (Balasubramanian 2008, Jones 2016).

UV radiation even for therapeutic purposes is compatible with breastfeeding (Beani 2010, Bae 2012).

Suggestions made at e-lactancia are done by APILAM team of health professionals, and are based on updated scientific publications. It is not intended to replace the relationship you have with your doctor but to compound it. The pharmaceutical industry contraindicates breastfeeding, mistakenly and without scientific reasons, in most of the drug data sheets.
