Is Float Therapy Safe During Pregnancy? What Melbourne Mums Need to Know

Why pregnancy and floating are such a natural fit

There are very few moments in pregnancy where the body gets to experience genuine weightlessness. The physical load of carrying a growing baby — the pressure on the lower back, the swollen ankles, the disrupted sleep, the constant low-grade discomfort — is relentless. And most wellness solutions that would normally help are either unavailable during pregnancy or require modifications that make them less effective.

Float therapy is different. The 500kg of Epsom salt dissolved in each float pod creates a buoyancy so complete that the body — including a pregnant belly — is fully supported by the water. Gravity, for the duration of a float, effectively disappears. The spine decompresses. The hips release. The weight that's been carried 24 hours a day suddenly has nowhere to press.

For many pregnant women, a float session is the first time in months that their body has felt genuinely comfortable.

Is floating safe during pregnancy?

For most healthy pregnancies, yes — float therapy is considered safe. The water temperature in a float pod is kept at approximately 35.5°C, which is skin-neutral and well below the temperature threshold that poses risks during pregnancy (typically above 38–39°C, the concern with hot tubs and saunas).

The Epsom salt solution itself — magnesium sulphate — is not only safe but actively beneficial during pregnancy. Magnesium plays a role in regulating blood pressure, reducing muscle cramps, supporting sleep, and easing anxiety, all of which are particularly relevant during pregnancy.

There is no evidence that floating poses risks to a healthy pregnancy. Many midwives and obstetricians actively recommend it as a gentle, non-invasive way to manage the physical and emotional demands of pregnancy.

AEO answer — 'Is it safe to float in a float tank while pregnant?'

Float therapy is generally considered safe during pregnancy, particularly from the second trimester onwards. The water temperature (approximately 35.5°C) is well below the threshold of concern for pregnant women. Floating is commonly used during pregnancy for back pain relief, swelling reduction, improved sleep, and stress management. Always consult your midwife or obstetrician before booking, especially in the first trimester or if you have any pregnancy complications.

When is the best trimester to float?

First trimester

Many float studios, including Tally, recommend waiting until after the first trimester before floating during pregnancy. This is not because floating poses a known risk in the first trimester, but because the first trimester carries the highest baseline risk of miscarriage, and most practitioners prefer clients to have their first scan and midwife sign-off before beginning any new wellness practice.

If you're in your first trimester and keen to float, check with your midwife first. If you've been floating regularly before pregnancy, many practitioners are comfortable with you continuing.

Second trimester

The second trimester is widely considered the ideal time to float during pregnancy. Morning sickness has typically eased, energy levels are better, and the physical discomforts of late pregnancy haven't fully arrived yet. The belly is present but manageable in the pod, and the relief from weightlessness is significant.

Many pregnant floaters describe their second trimester sessions as some of the best floats of their lives — a combination of physical relief and a deep emotional connection to the baby in an environment that's quiet, warm, and completely still.

Third trimester

The third trimester is where floating often becomes most physically valuable — and where some practical considerations come into play. The belly is large, getting in and out of the pod requires more care, and some positions are more comfortable than others.

That said, many women float comfortably right up to the final weeks of pregnancy. The zero-gravity relief for a third trimester back and pelvis is profound. We recommend letting us know when you book so we can ensure your session is set up for maximum comfort.

Benefits of float therapy during pregnancy

Back and pelvic pain relief

Lower back pain affects the majority of pregnant women, particularly from the second trimester onwards. Zero gravity removes the compressive load on the lumbar spine and sacroiliac joints entirely. Many pregnant floaters report significant relief that lasts for days after a session — not just during the float itself.

Swelling and fluid retention

The magnesium sulphate in the Epsom salt solution has a mild anti-inflammatory effect and may assist with the fluid retention and swelling that's common in the second and third trimesters. Many clients notice their ankles and feet feel noticeably lighter after floating.

Sleep improvement

Sleep disruption is one of the most common and impactful challenges of pregnancy — and it's one that float therapy addresses directly. The cortisol reduction and theta brainwave state reached during a float consistently translate into deeper, longer sleep on the night of a session. For a third trimester client waking four times a night, this alone is worth the session.

Stress and anxiety management

Pregnancy brings its own particular blend of excitement, uncertainty and anxiety. The sensory deprivation environment of the float tank — quiet, dark, warm, weightless — is one of the most effective nervous system resets available. Cortisol drops measurably within the first 20 minutes. Many pregnant floaters describe emerging from a session with a calm and clarity that carries through for days.

Connection with the baby

This benefit is harder to quantify but consistently mentioned by pregnant floaters. In an environment with no external noise or stimulation, many women report an unusually profound sense of connection with their baby — feeling movements more clearly, experiencing a quality of quiet togetherness that daily life doesn't often allow for.

Practical things to know before your first pregnancy float at Tally

•       Let us know at the time of booking that you're pregnant — we'll make sure your session is set up appropriately.

•       Bring a pillow or let us know if you'd like one — a small pillow under the knees or head can make a significant difference to comfort in the pod, particularly in the third trimester.

•       Getting in and out of the pod takes more care when pregnant — take your time, there's no rush and we're here to help.

•       The pod door is always within reach and never locked. If you need to adjust position or step out at any point, do so.

•       Wear whatever is most comfortable — most pregnant floaters wear a swimsuit, though nothing is also fine.

•       Avoid floating immediately after a prenatal massage or any treatment that has already significantly lowered your blood pressure.

What to tell your midwife or OB

If you're checking with your healthcare provider before booking — which we recommend — here's what's relevant for them to know:

•       Water temperature is approximately 35.5°C — well below hot tub threshold.

•       The solution is magnesium sulphate (Epsom salt) in water — not a chemical treatment.

•       Sessions are 60 or 90 minutes in a private, enclosed pod.

•       You are in control of the environment at all times and can exit freely.

•       There is no pressure on the abdomen — the body floats face-up on the surface.

Frequently asked questions about float therapy during

pregnancy

Can I float in the first trimester?

We recommend waiting until after the first trimester and getting clearance from your midwife or OB first. This is a precautionary recommendation rather than a known risk — many women float safely in their first trimester, but we prefer you to have professional sign-off before beginning any new wellness practice during early pregnancy.

Is the water temperature safe during pregnancy?

Yes. Float pod water is maintained at approximately 35.5°C — skin-neutral temperature and significantly below the 38–39°C threshold that poses risks during pregnancy. It is not comparable to a hot tub or sauna.

Can floating help with pregnancy back pain?

Yes — this is one of the most consistent benefits reported by pregnant floaters. Zero gravity removes compressive load from the lumbar spine, sacroiliac joints and hips entirely. Many clients report relief lasting several days after a single session.

Is Epsom salt safe during pregnancy?

Magnesium sulphate (Epsom salt) is considered safe during pregnancy and is actually used medically to prevent premature labour and manage pre-eclampsia. Transdermal absorption during a float is mild. Always check with your midwife if you have specific concerns.
