Benefits - Hot Sauna then Cold Plunge :)
We recently visited the South Island of NZ and found a “secret sauna” by the lake. We spent an hour alternating between hot saunas (90 degees for approx. 15 minutes) and cold plunges in the lake (approx. 30 seconds in an icy 8 degrees!). The temperatures felt extreme but we felt pretty amazing afterwards, prompting me to find out more about the benefits of such practices!!
Benefits include:
•Circulation and vascular health: Sauna heat causes vasodilation, a widening of the blood vessels, increasing blood flow to the skin and muscles. Cold plunges cause vasoconstriction, a narrowing of the blood vessels, moving blood back toward the core. The alternating pattern can train the vascular system to respond quickly to temperature shifts and support overall vascular function.
•Muscle recovery and performance: heat relaxes tight/stiff muscles and helps to ease tension after training. Cold reduces inflammation and soreness. The combination may enhance perceived recovery, particularly for athletes integrating hard training blocks or post-workout recovery.
•Pain relief and relaxation: eased muscular tension with a calming contrast. The contrast can create a sense of pain relief and improved comfort in sore areas.
•Nervous system mood and effects - the contrast between heat and cold helps to promote parasympathetic activation, promoting relaxation and stress reduction.
•Sleep: relaxation and cooling afterward can aid sleep for some.
Some safety tips include :
•Start gradually: shorter times, milder temperatures and build up gradually
•Watch for symptoms: stop if you feel dizzy, faint, or experience any chest pain.
•Hydrate well before and after use
•Contraindications include pregnancy, heart conditions or fever/illness.
This experience and knowledge has got me researching facilities in my local area!
Would love to hear any of your own experiences in the comments below
Yours in good health,
