Tourmaline is a natural mineral that, when warmed by your body heat, emits gentle far-infrared radiation — a wavelength of heat that penetrates below the skin surface into muscle tissue. This promotes circulation, relaxes muscle tension, and provides deeper-feeling warmth than a standard heat pad. No batteries, plugs, or activation is required — it works simply from the heat of your body.\u003c\/p\u003e\n\u003ch3\u003eCan I wear it all day at work?\u003c\/h3\u003e\n\u003cp\u003eYes — the Therma Brace is designed for continuous daytime wear. The breathable outer shell and adjustable Velcro closure make it comfortable for long shifts on your feet, driving, or desk work. Many users find it most useful during cold weather months or in air-conditioned environments where muscle stiffness tends to be worse.\u003c\/p\u003e\n\u003ch3\u003eIs the self-heating brace suitable for arthritis?\u003c\/h3\u003e\n\u003cp\u003eGentle heat therapy is widely used to manage joint stiffness and muscle discomfort associated with arthritis, particularly osteoarthritis of the lumbar spine. The low-level, sustained warmth from the tourmaline lining is well-suited to this use. For inflammatory arthritis (such as rheumatoid arthritis), where heat can occasionally aggravate inflammation during flares, we recommend consulting your rheumatologist before regular use.\u003c\/p\u003e\n\u003ch3\u003eCan I wear it during exercise or physical activity?\u003c\/h3\u003e\n\u003cp\u003eThe Therma Brace provides both thermal therapy and lumbar compression, making it suitable for light physical activity such as walking, gentle gym work, or everyday tasks. For high-intensity exercise or heavy lifting, a standard non-heated lumbar belt may offer more structured support. The self-heating element becomes more effective as your body warms up during activity.\u003c\/p\u003e\n\u003ch3\u003eIs it machine washable?\u003c\/h3\u003e\n\u003cp\u003eWe recommend hand washing the Therma Brace in cool water with a mild detergent and air drying it flat. Machine washing on high temperatures can degrade the tourmaline fabric and Velcro fasteners over time. Do not tumble dry. Regular gentle washing will maintain the integrity of both the heating properties and the lumbar support structure.\u003c\/p\u003e","brand":"ActiveSupport UK","offers":[{"title":"Black \/ M","offer_id":56994484584831,"sku":"ZLDOSZV","price":28.82,"currency_code":"GBP","in_stock":true},{"title":"Black \/ L","offer_id":56994484617599,"sku":"Y8A39CI84","price":29.27,"currency_code":"GBP","in_stock":true},{"title":"Black \/ XL","offer_id":56994484650367,"sku":"4O3MSH7R1","price":29.74,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0981\/3239\/4367\/files\/I2ryx5I9T5bz2Pz7.webp?v=1771611218","url":"https:\/\/www.activesupportuk.co.uk\/products\/therma-brace-self-heating-lumbar-support","provider":"ActiveSupport UK","version":"1.0","type":"link"}
