Why reminders work
Thirst is a late signal — by the time you feel thirsty, you are already mildly dehydrated. Studies on habit formation show that a regular external cue beats willpower for building consistent habits. A gentle nudge every hour turns “drink more water” from a vague goal into an automatic routine.
