The thought might be a little shocking but even just several seconds under cold water can bring about many benefits. These include improved blood circulation and muscle recovery. When it comes to pain management - exposure to cold water causes blood vessels to constrict, helping to reduce any swelling in the body that causes pain. It can also slow the speed at which nerve signals conduct impulses, thereby lowering our perception of pain. Cold showers can further strengthen our immune systems as the shock of cold water in the bloodstream stimulates leukocytes, increasing our resistance to common illnesses, like colds and the flu. Other benefits include increased metabolism and alertness. Need another reason to warm up to a cold shower? Hot water tends to dry out our skin, but cold water will tighten and “seal” our cuticles and pores preventing them from getting clogged. Cold showers make hair appear shinier, stronger, and healthier by flattening hair follicles, and increasing their ability to grip the scalp. And last but not least - cold showers also have an antidepressive effect! The intense impact of cold receptors in the skin send an overwhelming amount of electrical impulses from the peripheral nerve endings to the brain, boosting our mood and creating a pick-me-up effect. If the idea is still too chilling, no need to take a cold plunge into hydrotherapy, instead ease into the habit, testing your limits a little more with each daily shower.
