Contrast Showers is the technique of alternating between cold and hot water while showering. There are many benefits to both hot showers and cold showers but doing contrast showers provides additional benefits that you would not get any other way.
Exposure to cold showers can increase the synaptic release of noradrenaline in the brain and levels of beta endorphins in the blood by activating the sympathetic nervous system.
Cold receptors in the skin send overwhelming electrical impulses to the brain from peripheral nerve endings resulting for some in an anti-depressive effect.
The temperature contrast creates a pump effect that flushes lactic acid in your body which builds up during exercise.
The hot water dilates blood vessels and increases circulation, while cold water constricts blood vessels decreasing blood flow.
