Hydration Routine

The review summary this routine was written from is about drinking strategy: drinking to thirst performed at least as well as programmed drinking for endurance despite greater dehydration, with the difference described as likely trivial; cool drinks below 22 C raised voluntary intake by roughly 50-180%; post-exercise rehydration needed about 150% of the fluid deficit with sodium; and caffeine up to 400 mg a day did not cause meaningful dehydration. What that supports is thirst being a largely adequate guide, not any particular daily volume or schedule - it establishes no dose-response, so the daily five-minute routine framing here is a reasonable design choice rather than a research-backed number.

• Set it up rather than schedule it: a filled bottle or glass where you already sit, work and eat, so drinking happens without counting.
• Drink when you are thirsty and use urine color as the rough gauge - pale yellow is the target, dark means you are behind.
• Add fluid in heat and during or after exercise; expect to need noticeably more on those days than on a cool desk day. Chilled water is usually easier to drink more of if you struggle to get enough down.
• Swapping one sugary drink a day for water or an unsweetened option is a separate habit worth pairing with this - it is not part of the drink-to-thirst approach itself.
• If you have a fluid restriction from heart or kidney disease, follow the targets your clinician set; the thirst-and-urine-color approach does not apply to you.
