I started sea swimming over the summer and want to keep it up as long as I can, but the last two sessions had me frozen afterwards. I'm out of the water an hour and despite a hot shower (and even drying my hair), I'm wearing a wool jumper, wool dress, fleece, thermal tights and I've just had a cup of tea, I'm still freezing. I've the kettle boiling again for more tea and a hot water bottle.
