How to Actually Drink Enough Water

The book covers how much water you need — a big glass on waking, one at each meal, more around workouts, roughly half your body weight in ounces a day. Knowing the target is the easy part. The hard part is that drinking that much water is genuinely a little unnatural, and most people never manage it. This is about the small tricks that make the target achievable instead of aspirational.

Start with the core problem: thirst is a bad signal to rely on. By the time you feel thirsty, you're usually already mildly dehydrated — thirst is the alarm that goes off after you've fallen behind, not a reminder to stay ahead. So "drink when you're thirsty" quietly guarantees you spend much of the day playing catch-up. The fix is to drink on a schedule, not on a feeling.

The easiest way to do that is to stop treating water as its own task and attach it to things you already do. Trying to remember to sip throughout the day rarely sticks. Linking each drink to an existing habit does. A large glass the moment you wake up. A glass with lunch and with dinner. A glass before your workout and steady sips during it. Because each drink is tied to something already on autopilot, you hit your target without tracking anything — the habits do the remembering for you. This is the single highest-leverage change: it turns hydration from something you monitor into something that just happens.

A couple of smaller tricks make the volume itself easier:

Try warm or room-temperature water instead of ice water. In the US we default to cold water because it's refreshing — but refreshing and easy to drink in volume aren't the same thing. Cold water tends to be sipped; warm or room-temperature water goes down in larger, easier amounts. If you've ever struggled to finish a big glass of ice water but can drink tea effortlessly, you already know the effect. For getting real volume in, warm water will make it significantly easier.

Consider a small pinch of salt in your water — with a caveat. Here's something that catches people who clean up their diet: when you shift from processed food to whole foods, you dramatically cut your sodium intake, because most dietary sodium comes from processed food, not the salt shaker. Sodium is an essential electrolyte, and going too low can leave you feeling flat even while drinking plenty of water. A small pinch of salt in a glass or two helps your body actually use the water, and it gently maintains a little thirst so you keep drinking. The caveat matters, though: this is general guidance, not for everyone. If you have high blood pressure, kidney issues, or any condition where your doctor has told you to watch sodium, skip this and talk to them first. For most healthy adults eating a whole-foods diet, a little added salt is helpful rather than harmful — but it's the one tip here worth checking against your own health situation.

Put together, the approach is simple: don't wait for thirst, attach your water to habits you already have so it happens automatically, and use warm water and a touch of salt to make the volume easier to reach. Do that and hitting your target stops being a daily effort of will and becomes just part of how your day runs.

If you're just getting started and need the reminders, a tracking app can bridge the gap until the habits stick. WaterMinder is a solid choice — it reminds you to drink and tracks your intake through the day, which is genuinely useful in the first few weeks while you're building the habit. The goal is to stop needing it: once each drink is anchored to a meal or your workout, the reminders become redundant and you can drop the app. It's training wheels, not a permanent fixture.
