Going again tonight. I asked this on the "My First Tri Training..." thread, but will ask again here.
Anyone experience dizziness/nausea and any top tips to avoid it?
I can do 2-2.5km continuous in a pool no probs. Quite happy and confident in the open water. Went slow, breathing easy, not for for my first time (600m) not panicky. But by the time I got out of water, my head was spinning. I nearly fell over walking back up the beach. Felt the dizziness while in the water too.
Theories:
1. Can't see horizon or sides or bottom, so no visual feedback on movement = motion sickness?
2. Opposite: looking around at pretty scenery, lifting head more than in a pool = rolling around and motion sickness?
3. (Debs theory?) Brain freeze due to cold water (9.9C someone said) no gimp hat and full face mask, just a swim cap and small goggles, so face was cold and quite sore for first first 100m or so, but then just got on with it and it prob went a bit numb, as did feet and hands. (Orca Kinesis wetsuit, borrowed from Tri Shop at waterside, btw. It was great really comfy and no cold water in at all!)
Any thoughts from the OW Massive? Thanks. :-)G

Think it's 3 - doesn't the body realise parts of the body are V cold and reduce blood flow to those areas (hence we go pale) so you probably have not much blood in hands/feet/head. Obv the brain doesn't work too well hence dizziness, especially when you stand up.
I had this and now use 2 or even 3 hats when water is cold. The thicker silicone ones are quite good (Zoggs?) for this, rather than the very thin ones you tend to get issued for races.

Happy - you suffered from hypotension as a result of reperfusion of your cold skin and peripheries when you got out?

But it wasn't just when I got out Argie. I was feeling dizzy while in the water. So it's nothing to do with reperfusion (though it might have got worse when I got out.) But if you are saying while in water, generally reduced blood flow, espesh in head, when exercising in the cold, = dizziness, then that makes sense.
Would acclimatising to the cold help? Or will it just get worse, the longer you are in the water and the longer you are cold. Thanks folks. :-)G

Googling also suggests ear plugs may help (reduces heat loss and general water sloshing about in ears)?

And one more tip...?
. Blow bubbles before taking off on your swim. When the cold water hits your face, the shock causes your lungs to contract, causing breathing problems. Go waist deep into the water and submerge your face to blow bubbles. This helps alleviate the shock of the cold water.

Happy, funnily enough, someone last night who has suffered with dizziness last year tried earplugs last night and said he was ok when he got out
