IHWG as a scientific working group, one of our mission is to sharing hydration knowledge to general people, and we were realized on that time how strong the relation both hydration and kidney, so we pleased and proud to join gimmick with the other event – Funwalk by Pernefri. This event was held in Jakarta Car Free Day Area, Indonesia. We shared hydration knowledge by gimmick – are education hand-held fan and goodie bag. Glad to know that it is very useful for them, they read it and use it as its function! Hopefully it can raise their knowledge :)
