Long night and you still have a lot to do. What would be the most common conduct you would follow? A nice refreshing splash to the face!
But why does this makes us feel more awake? Why does it make us feel calmed?The mammalian diving reflex is a reflex which optimizes respiration, therefore creating physiological reactions that allow our bodies to feel better.
Some of the physiological effects that the cold water creates are bradycardia (slow heart heart) which lessens the need for bloodstream oxygen, leaving more to be used by other organs, vasoconstriction and blood shift which all create relaxation effects in our bodies.So next time you feel a little stressed you might want to give yourself a little splash on the face to regain some energy!
