What is allowed while breastfeeding? – Sports, medication, dentist, sauna, and more

When you find out you are pregnant, joy often comes with a wave of worries.
Worries about whether everything will go well, how the birth will be, and whether you will have enough milk for your baby.

Then, new questions start to appear: Can I dye my hair or paint my nails? What can I eat or drink – and what should I avoid? What about sports, swimming, or going to the sauna? Can I take medicine if I have a headache? What if I need a dentist, an X-ray, or an ultrasound?

These are all common concerns, and the answers are not always easy to find. In this article, we look at what is and isn’t recommended during the breastfeeding period.


Can you exercise while breastfeeding?

Yes! Exercise is safe and even beneficial while breastfeeding.

Can you go swimming while breastfeeding?

Yes. Swimming is a gentle, healthy activity. Wait until after the first six weeks postpartum, and always follow basic hygiene rules. A quick shower after swimming removes chlorine – your baby won’t notice a thing.

Can you take painkillers?

Yes, certain painkillers are safe during breastfeeding. Ibuprofen (Nurofen, Advil, Algoflex) is considered safe. Paracetamol is also widely recommended. You don’t need to suffer in pain – one tablet will not harm your baby, as long as you follow dosage and timing guidelines. For severe or ongoing pain, consult a doctor.

Can you get anesthesia at the dentist?

Yes. Local anesthesia with lidocaine is safe and enters breast milk only in minimal amounts. If you prefer, you can let your dentist know that you are breastfeeding, but there is no need to avoid treatment.

Can you have an X-ray or ultrasound?

Yes, both are safe. They do not affect breast milk supply or quality. You can breastfeed as usual after these procedures.

Can you dye your hair, paint your nails, or use body lotion?

Yes. Only minimal amounts of these substances are absorbed through the skin, and they do not harm your baby. Choosing products with natural ingredients is healthier for both mother and child.

Can you go to the sauna?

Yes. Just make sure not to stay inside too long and drink enough water to stay hydrated.

Can you go tanning or use a solarium?

Yes. The only concern is avoiding sunburn. Keep in mind that tanning and solarium use increase the risk of skin cancer, so moderation is important.
