Calcutta is chilling. Normally, during winter, like many,  I take bath picking up  mugfull of warm water from the bucket. Yesterday I took bath, still using the same  warm water. But this time I used shower to spray water. My feeling was somewhat uncomfortable, I felt little more shivering than when I poured the water from the mug. The question is !! TRUE/FALSE. If it's true  what's the science behind it ?
