Cold therapy stimulates the vagus nerve, triggering a parasympathetic response that lowers heart rate and promotes calmness. This process reduces cortisol levels, helping manage stress and anxiety while improving focus and emotional resilience.

Cold exposure stimulates the release of hormones like norepinephrine and adrenaline, which can increase alertness, focus, and overall energy levels. It can provide a natural boost and enhance mental and physical performance.

Cold therapy, such as ice packs or cold water immersion, reduces inflammation by constricting blood vessels and slowing the release of inflammatory mediators. This helps decrease swelling, alleviate pain, and accelerate recovery from injuries or intense physical activity.

Lowering core body temperature through cold exposure before bedtime can regulate the sleep-wake cycle by stimulating the release of melatonin. This process promotes relaxation, reduces muscle tension, and facilitates deeper, more restorative sleep.

Cold therapy has been shown to activate the immune system, leading to an increase in immune cell activity and the production of certain cytokines. This can enhance the body's defence against pathogens and support overall immune function.

Cold therapy, including ice packs or cold baths, can help alleviate muscle soreness and reduce inflammation following intense physical exercise. The cold temperature constricts blood vessels, reducing blood flow to the affected muscles and minimising the buildup of metabolic waste products associated with muscle soreness.

Cold exposure activates brown adipose tissue (BAT), a type of fat that generates heat by burning calories. When exposed to cold temperatures, BAT is stimulated, leading to increased energy expenditure and potentially aiding in fat loss over time.
