If you're over fifty and you're awake at 3 a.m., you've probably decided it's just your age now. It usually isn't. Here's the part that rarely gets explained. Falling asleep isn't the hard bit for most men after fifty. Staying asleep is. And your body doesn't decide to sleep because you're tired — it decides because your core temperature drops. That drop is the signal. Heat up, then cool down, and the cooling is what tells your nervous system the day is finished. Most of what gets sold for sleep skips that entirely. Melatonin, magnesium, the app that plays rain. None of them build the temperature swing your body is actually waiting for. Jim LaValle has spent forty years as a clinical pharmacist and board-certified clinical nutritionist, and he sits on our scientific advisory board. His point is that the benefit isn't only the heat — it's the cooling down afterwards, and the shift that creates. His protocol is twenty minutes, four times a week, at a temperature you can genuinely tolerate. That last part matters more than people think. A traditional sauna sits at 200°F and heats the air around you, which is why twenty minutes in one feels like an endurance test. The Solara runs at 150°F because infrared doesn't heat the air. It uses radiant wavelengths that warm your body directly, penetrating three to four centimetres — into the muscle and the connective tissue around a joint. Lower number, more of it where you need it, and a temperature you can actually sit in long enough for the protocol to mean anything. It's a one-person full-spectrum infrared sauna with medical-grade 660nm red light built in. It plugs into a standard outlet and draws about what a hair dryer does. Thirty-minute setup, two people, no drills, no power tools, no electrician. It's small enough for the corner of a bedroom or a spare room, and the front glass is reflective, so nobody walking past the doorway sees anything. Twenty minutes. Door shut. Then the part that does the work — getting out, and cooling down. Certified free of toxic heavy metals and phthalates. Ultra-low EMF. Free shipping.
