Cold plunging is popular these days for its health benefits, but these aren’t quite what they’re commonly believed to be, and definitely different for women, maybe even for older men.
Cold immersion can release hormones that have positive effects on the body and mind, but it doesn’t burn fat or reduce weight. It can activate fatty tissue to generate more heat and even change it so that it continues to do so, rather than store more fat.
But some studies have shown that it may increase the amount of fatty tissue.
Importantly, women respond differently to cold immersion.
Men shiver more when cold, using this activity to generate heat from the muscles. This is a male Yang response.
Women constrict blood vessels,to keep more blood in the core and keep it warm. This is a female Yin response. And less feel-good hormones are released. During the second half of their cycle women’s bodies are warmer and they experience a greater drop in core temperature when they enter cold water. So it feels more intense, more uncomfortable, and takes longer to recover from. And the increase in cortisol it causes is greater and takes longer to drop.
Finally, immersion during the period may increase pain and cramping and feel generally more intense and less enjoyable.
Women respond better to cold immersion in warmer water, 14 to 15 degrees Celsius for 2 to 5 minutes, and they should minimise cold bathing during the second half of the period and during menstruation. And maybe give it a miss altogether if you’re trying to conceive.
A recent study showed that female rats immersed in cold water gained weight and became less fertile from inflammation in the reproductive organs.
This is consistent with what Traditional Chinese Gynaecology has always said.
There are many prescriptions designed to treat infertility and menstrual pain due to cold.
How about older men?
Sorry, old mates.
We become a little less Yang as we age.
Cold immersion can have health benefits, but because of the greater risk
of it causing heart problems, we should take it easy.
Use warmer water and start off with staying in for a minute or less. Some warn against extending this time to any more than 3 minutes.
Older people should enter cold water slowly.Diving straight in gives conflicting messages to the heart, which are more likely to cause heart attacks in older people. Get the body cold before you hold your breath and immerse your head.
In winter southern Australian ocean temperatures could be just right, or a little cold depending where you are.








It’s 36 degrees for days in Spring and that fan feels so good. But wind is the seasonal pathogen of spring, and we are easily damaged by it. I wrote a little more about that on the
