Between 5 to 15 degrees, seriously! This is too cold for my body, well, if there is much blood circulation in your body then it will keep you warm but normally I won't be able touch the water in that kind of temperature. Congratulations on your achievement.
@tibroo Really so. A cold shower is familiar to me. But the impressions, the sounds of the waterfall and the freshness are incredible :)
Though it is incredible but it can cause harm to our body if we do not have practice or strength to take that cold.
