I have been toying with cold water swimming for some time. ... (Now I'm no longer on the brink of chilblains at all times it seems like it could be a reasonable endeavour!)
Does anyone do cold water swimming (or similar) and feel any benefit?
I've done some very brief reading about brown fat and thyroid function and cold water swimming increasing brown fat levels.
It might be an interesting thread in the fabric! π₯Άπ€πΌ

This might be worth reading: Health effects of voluntary exposure to cold water β a continuing subject of debate tandfonline.com/doi/full/10...
'When looking at the effect of regular cold-water exposure on parathyroid- and thyroid hormones, a study by KovaniΔovΓ‘ et al. suggests that regulation of PTH and thyroid hormones during cold exposure in humans varies by cold acclimatisation level and/or cold stimulus intensity. After 15 min of swimming in ice water, an increase in parathyroid hormone (PTH) and thyroid-stimulating hormone (TSH), as well as free T3, has been reported [Citation41,Citation75]. '
I stumbled on a website that purported cold water swimming to be a 'cure' for hashi's, which I think is codswallop, but it's where I read about brown fat & thyroid.
I suspect it's going to be a 'try it and see' thing but interesting there is research on it.
I've not tried it myself, but suspect that it could cause issues for anyone who's not optimally medicated with thyroid hormones. So yes, if you're hormone levels are good and stable, give it a try, but make sure you have someone with you.
"After 15 min of swimming in ice water, an increase in parathyroid hormone (PTH) and thyroid-stimulating hormone (TSH), as well as free T3, has been reported"
Surely this is a reaction to shock??
I wonder if watching a scary movie has the same effect? π±
or even better a hot bath stressing your body π
I am afraid I am with you TiggerMe on this one. Both the sea and rivers are full of pollution. I find myself longing for my home townβs old (now demolished) outdoor swimming pool. Of course it would be full of chlorine. I remember fondly the water was at its warmest when it was raining. Bliss.
I have been cold water swimming for 2 years and love it. Many people do it for mental health including me. In the water you can't help but be in the moment. It's exhilarating and lifts my mood. And the people you meet are lovely. It's also good for reducing inflammation. Key is to go in slowly, keep your head warm with a hat & know your own limits making sure you get out before you get tired. Dress as quickly as possible in lots of loose layers and take a bath mat to stand on whilst getting changes. I'd say go for it but wait another month as the water is coldest in March.
My son does the ice baths every morning. And he swears by them for mental clarity and increased immunity. Caveat: He has no thyroid issues (as far as we know). I tried this a couple of times, but don't seem to be able to get warm again for quite some time. I'm more of a sauna kind of girl. From what I understand the benefits are similar.
It's so good to hear a positive report from someone else with a thyroid issue. I have friends that do it but I don't think their opinions are relevant to me. π
I'm a cold water swimmer too, love it, feel great afterwards but don't go as often as I would like. I'm always cold lately so have been going to an outdoor pool which has a hot tub and shower and changing room so I get warm again quicker afterwards. Please read up about it as others have said before you go and don't go alone.
No experience but of course Wim Hof is living proof that there's something in it. I was looking at his website for ideas on how to improve autonomic nervous system function. I'd only attempt it in an organised club with frequent water testing lol.
He's certainly enthusiastic lol. Not sure I'm going to share it, cold showers smack of punishment or school PE lessons π€£. But I'm nothing if not open minded.
I would start in May when water temp get to 17/18. It's always easier to go up the curve than down. Nowca have tested lakes / docks where you can swim with life guards etc. You can also rent wetsuits at some of the venues. I prefer to swim rather than dip but venues tend to welcome anyone whatever they want to do.
Personally, I live swimming in the open air but hate swimming past Sept. I remember one 3 degree water temp November that I decided it wasn't for me.
If you do try, have a tow float, brightly coloured hat and never swim alone. Read up about hypothermia - e.g you can suddenly start feeling lovely and warm and actually you're in trouble. One day you might be able tp do 5 mins then next 10 and then the next 5, it depends on you, the air temp, the water temp, the wind, all sorts of random factors.
I know some people love doing this, and it probably benefits them. But I'd add a word of caution. My Dad's heart attack was brought on by jumping into an unheated outdoor swimming pool on a hot day. That was definite.
I don't know how you prepare for cold water swimming, but I'd research that first.
My sister is hypo and swims in her local lido weekly. She says the pressure of the water and the weightlessness are good and the endorphin boost from the cold water's incredible. It also reduces her pain and inflammation and calms her nervous system. Before starting this she was putting her face into a bowl of cold water every day. A gradual build up is best.
