1. Calm Inflammation and Pain
Cold showers are notorious for helping with inflammation and pain. The cold water constricts blood vessels, reducing blood flow to the area, which goes on to reduce swelling and pain levels. Cold showers can slow down the brain's transmission of pain signals, because your senses are focusing on how cold the water is, while your body recovers.
2. Relax Itchy Skin
Another answer to ‘are cold showers good for you’ is that they soothe itchy skin, reducing the temptation to scratch. So if you suffer from eczema or psoriasis, try to temporarily relieve the itchiness with a cold shower.
