You decide what your tub is for on a given day — cold protocol or warm soak. The wide range lets you experiment with what works for your physiology. (Note: true contrast therapy — alternating cold and hot within a single session — requires a separate heat source like a sauna. The LUX can be set to either temperature on demand, but not both within minutes. We say this directly because the published contrast therapy research uses alternating immersion within a session, not single-machine cold-on-day-X \/ heat-on-day-Y.)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWorth knowing before you buy.\u003c\/strong\u003e If you run cold exposure immediately after resistance training, Roberts et al.

If you have unstable angina, severe coronary artery disease, untreated arrhythmias, uncontrolled hypertension, active anticoagulation, cold urticaria, Raynaud's phenomenon, or you're pregnant (especially first trimester), consult your physician before starting a cold protocol. Standard rheumatology guidance for Raynaud's is to AVOID acute cold exposure, not graduated-exposure-therapy. The cold-shock response in the first 30–60 seconds is the highest-risk window for cardiac events in pre-existing CV disease.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's included:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eX Tub (acrylic, 34\"+ depth, 3\" foam insulation)\u003c\/li\u003e\n\u003cli\u003eLUX High Performance Chiller and Filtration System (1.5 HP)\u003c\/li\u003e\n\u003cli\u003e3-year limited warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eFor the people who treat hormesis as a daily practice, not a content opportunity.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003ca href=\"https:\/\/calendly.com\/grant-exposuremethod\/30min\" target=\"_blank\" title=\"Book a 45-min consultation with the founder →\" rel=\"noopener\"\u003eBook a 45-min consultation with the founder →\u003c\/a\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003c!-- notionvc: 6fdb59f5-6db5-46b6-a95e-46c69b9f7338 --\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"RevX Wellness","offers":[{"title":"Default Title","offer_id":43238792560753,"sku":"RXW-0569","price":8500.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0676\/2089\/6881\/files\/transparent_-_lux_doors_open_x_tub_cold_plunge_side.png?v=1778704488"}],"url":"https:\/\/exposuremethod.com\/collections\/cold-exposure.oembed","provider":"Exposure Method","version":"1.0","type":"link"}
