Cold exposure has become a popular recovery tool. Here is what the evidence actually supports versus what is marketing hype.
Cold water immersion (10 to 15°C for 10 to 15 minutes) after exercise reduces perceived muscle soreness. It likely works through vasoconstriction reducing inflammation and swelling in damaged tissue.
Claims about dramatically increased metabolism, fat loss and immune supercharging are not well-supported at the exposure levels most people use. Brief cold showers are a wake-up signal, not a metabolic intervention.
Cold exposure and supplementation address different aspects of recovery. SodaPeak provides nutritional support (CoQ10 for cellular repair, Ashwagandha for stress adaptation). Cold exposure provides mechanical anti-inflammatory effects. They are complementary, not competitive.
