What temperature should I have my hot tub on ?

[Emz2019]

I am 7 months pregnant and now the weather has picked up we have decided to get the hot tub back up and running, I know 40 degrees can be too hot in pregnancy but does anyone know what the ideal temp should be in pregnancy?

I think it's best to avoid them.

Aren't Hot tubs (Jacuzzi?) Meant to be unsafe during pregnancy?

Just curious as all pools and spas ban pregnant woman from them.

If not - think it's body temperature only so BP doesn't make you crash and drown.

I also thought they needed to be avoided.

zero temperature as you shouldn't be in it!

Looking at that Nhs advice I'd say follow the guidelines for a hydrotherapy pool and go 35 degrees. To be honest I don't see why 37 would be a prob since it wouldn't raise your body temp. Since you can control the temp on your own it's different to using one at a spa (and you often see threads on here about it, many have with no ill effect). Like Nhs says it's about avoiding risk of overheating and obviously get out if you feel funny in any way. We booked a holiday cottage for when I'll be 7 months that has a hot tub and if it's controlled temp then I will use it.

I have a hot tub and asked a senior midwife about this last year. I have had multiple miscarriages, but got hot tub for back pain. I did not use it during any of the pregnancies where I miscarried, but wanted to know the science behind it.

She said the guidance came out as there was a rise in infection from poorly maintained hot tubs a few years back. In addition, like a hot bath, risk of fainting when you get out.

She actively encouraged me to use my own one, which is kept correctly balanced chemical wise. I'd didn't get a chance to but it was no longer on my list of many many things to worry about.

Its not to do with temperature. More to do with what bacteria could be in the water.

Hot tubs should be avoided. Someone I know lost their baby after being in a hot tub. She didn’t realise that it was unsafe until after she got out and was told by multiple people. Doctors also suggested it could have been a reason as to why she lost the baby.

Birthing pools are kept at 37 degrees so can't see why, in one you can set the temperature to the same or less you couldn't use it

toscacat because, as PP have said you can't be sure what's in the water

Found this article (among others) as I’m 35 weeks pregnant on holiday with a hot tub and really wanted to use it for a bit

It’s talking about saunas and hot baths but same principle about not
raising your core temp. If you set it below 37 there is no way it can raise your core temp to dangerous levels of 39, assuming the air temp is low and as it’s the U.K. it will be!. I set mine to 36 and had half hour soak and baby was enjoying the whole time.
I’ve looked into the literature and there is very little evidence that hyperthermia (raised body temp) has a negative effect in pregnancy, even less evidence outside of the first trimester. There are hardly any studies and the sample sizes are tiny. It’s all about listening to your body imo and jumping ship if you feel too hot. Evidence from women in Scandinavian countries has shown that pregnant women (nearly) all wimp out of saunas before their core body temps rise to dangerous levels as they start to feel too hot. Your body is good at protecting you! The evidence Just isn't there to be conclusive of risk or lack there of. It’s up to the individual to assess the risks, look at the evidence and make a personal decision based on that. For me that meant being past first T and enjoying it sensibly (below 37 degrees, not too long and no powerful jets)

Simply you shouldn't be in one

That's an interesting article, @readysetcake, I think it makes sense, from reading people's replies it sounds like the greater risk is from unsanitary water conditions, which owners of hot tubs can control but we can't rely on if going to a public facility.
