While many people claim that having an ice-cold shower in the morning has its benefits, doctors stay neutral.
There is a lot of research that needs to be done on the topic, but doctors believe that, yes, an ice-cold shower could relieve some muscle pain and itchiness, as your nerves can’t transmit multiple sensations at the same time. It can also cause a mental boost. Mainly, it’s the slap of cold water that wakes you right up.
On the other hand, abrupt submersion in cold water could put certain people at risk for heart complications, including heart attacks or strokes.
