Hydration Reminder / Timer
Why hydration reminders matter
Regular sips help maintain energy, focus, temperature regulation, and digestion. This tool schedules gentle reminders and tracks your intake toward a daily goal so you don’t forget to drink water.
The content here is informational and not a medical recommendation.
How the tool works
- Select Metric (ml) or Imperial (fl oz).
- Set your daily goal and typical serving size.
- Choose a reminder interval (e.g., every 30 minutes).
- Press Start to begin the countdown; you’ll see the next reminder time.
- Use Log Drink whenever you finish a serving to update progress.
- Pause or Reset the timer anytime. Copy or Share your daily summary if needed.
Units & inputs
- Units: Metric uses milliliters (ml); Imperial uses fluid ounces (fl oz).
- Goal: Total water you want to drink today.
- Serving size: Your typical sip/bottle/cup amount; it’s added each time you log a drink.
Only the fields for your chosen unit are shown to reduce mistakes.
Starter goals (general)
Adjust for body size, activity, climate, and medical advice.
Scheduling ideas
- Focus sessions: 25–30 min intervals (Pomodoro-style).
- Desk work: 30–45 min intervals to avoid frequent breaks.
- Training: shorter intervals (15–20 min) and smaller servings.
- Evenings: extend to 45–60 min to reduce sleep disruption.
Helpful tips
- Keep a bottle within reach and pre-fill it to your serving size.
- Log immediately after drinking so progress stays accurate.
- Use cooler intervals during meetings; tighten them during workouts.
Common mistakes
- Setting a goal that’s too high at the start—ramp up gradually.
- Logging “bottle size” that doesn’t match what you actually sip.
- Ignoring climate and training days when choosing a goal.
Frequently asked questions
What counts toward my total?
Water is best. Unsweetened tea and coffee contribute, but caffeine can have a mild diuretic effect in some people. Sugary drinks add calories; consider tracking them separately.
How do I pick a daily goal?
Start with 2000–2500 ml (68–85 fl oz) and adjust for body size, climate, and activity. Listen to your thirst and monitor urine color (pale straw is a common rule of thumb).
Can you over-hydrate?
Yes—excessive intake without electrolytes can be risky (hyponatremia). Don’t force large volumes quickly; spread intake across the day and follow professional guidance during endurance events.
Does the tool work offline?
The reminder and progress features run in your browser; some functions may pause if the page is closed or the device sleeps. Keep the tab open for best results.
