For starters, it certainly serves as a good wake-up call. By Janice Sim
While most of us would shudder at the thought of showering in icy cold water, these perks of skipping out on a warm, soothing shower might just change your mind. If you're not accustomed to bathing in cold temperatures, you can start gradually with 10 seconds within the time you spend in the shower. As your body gets used to it, you can slowly start to bump it up to 20, 30 seconds before hitting a full minute. Ideally, your goal is to have 5 minutes of cold shower time. However as cold showers can shrink up your blood vessels, if you have high blood pressure or a heart condition, do not attempt this before consulting your doctor.
