Swimming while pregnant and with a young baby - lake, pool and spa

The sun is out, it's warm, it's beautiful; swimming season has well and truly arrived! Lake, pool, hot tub... not all bodies of water are equal when young children or pregnant women are involved. Here is the essential information to keep in mind.

Pregnant women and babies are more vulnerable

Pregnant women are more susceptible to infections, as are babies under one year old, whose immune system and thermoregulation are still immature.

Even though there is no official public health guidance on swimming during pregnancy or in infants, it does seem logical and consistent to follow the advice of health professionals, who favour prevention over treatment.

Lakes and rivers: to be avoided

These waters can contain bacteria, viruses, parasites, algae and pollutants. Swimming in natural water is not recommended for babies under one year old, and also carries risks for pregnant women (skin, vaginal, respiratory or gastrointestinal infections).

Public pool: possible, with precautions

  • From 6 months for your baby (some professionals say as early as 3-4 months if your baby holds their head well and the parent feels confident and can keep them safe)
  • Never put their head under water
  • Check the water quality (posted chlorine/salt levels)
  • Avoid the sunniest hours (11 a.m. to 3 p.m.) and busy periods
  • Bring a swim diaper
  • Take your baby out if they cry, are cold or seem tired

Home pool: more flexible

If the water is well maintained, a baby can swim in it from 1 month, ideally in the shade. It is also an excellent way for a pregnant woman to relax. During hot spells in the summer, mothers who are breastfeeding are often encouraged to do so in their own pool, in the shade, for their own comfort as well as that of their baby, who is less hot while snuggled against their mother.

Hot tub: not recommended

The high water temperature is a problem for babies as well as for pregnant women (risk of miscarriage, malformations, a drop in blood pressure, varicose veins). On top of that, the contamination factor can also be present in public hot tubs.

If a pregnant woman still chooses to go in: never in the first trimester, 10 minutes maximum, setting the temperature so it is not too hot, once a week, and always with someone else present. Get out immediately if you feel any unpleasant symptoms.

A practical tip

To avoid thermal shock when coming out of the water, take off your baby's swimsuit while they are still in the water, then wrap them in a towel right away.
