Medical explanation.
Cold water acts as a vasoconstrictor - in short, your peripherals such as your arms and legs get alot less blood because the core suddenly thinks it needs to survive and reduces the blood flow rapidly. This rapid vasoconstriction also forces up blood pressure, up goes the heart rate and so up goes the resperation rate to get enough oxygen for that faster beating heart, and then up goes the blood pressure... so on and so on. The body is just trying to preserve the core organs, and yes it will allow the brain to die first before the heart and liver... The cramps in your feet are also signs that your bodies not getting its required fuel and blood to remain 'alive', and the pain is just a way of your body telling you this.
(You will get a head ache as the brain is suddenly assaulted by freezing temperatures, the body reacts by shutting down as many and as much blood vessels and capillaries as it can to preserve heat, and in short, your starving your brain of the required nutrients for its survival. Hence you get a head ache.)
I lived in the cold for a long time, and I can tell you now for free that if your in any temperature below or approaching freezing and you start showering under cold water, you are not going to remain healthy for long. Heat your water and use a flannel or sponge. A cold shower on top of an already cold body? meh.... thats not a route I will be going down any time soon.
