Hot and cold showers
If you are like me, the thought of taking a cold shower is not at all inviting, at least initially. It was not until I was at a hot springs that offered a cold plunge pool that I actually gave this “contrast bathing” a try. I have to say, it was rather invigorating to go from a hot pool to an ice cold one (and back to a hot pool!). Not only is it believed to improve circulation, it is also rather energizing!
Why should you try it?
The basic concept of alternating warm and cool water during a bathing session is a treatment known as contrast baths and have been used for over 2,000 years. This type of treatment causes rapid changes from warm to cold which help to quickly open and close tiny capillaries in the body. Warm causes the small arteries to open; while cold causes them to contract or close. This rapid opening and closing creates an internal pumping action that is believed to help decrease inflammation.
What are the Potential Benefits?
Increases blood flow and skin temperature (i.e., circulation)
Helps inflammation
Can help with mobility
May reduce pain
Improves immunity and lymphatic function
The stress reaction in the body helps prime the adrenal glands to prepare for stress efficiently
How to take an alternating hot/cold shower:
Start your shower a little warmer than usual to get your entire body wet. After your body is warmed up, after 2-3 minutes, change to cold water and cover your entire body, including your head and face. Aim for 20-30 seconds.
Switch back to hot for another 2-3 minutes and repeat as noted above.
Repeat for 3 cycles
If you are showering in the morning, I suggest finishing with cold and if showering at night, ending with hot. The cold will energize you, the heat will help relax you.
