Infused water: 8 ideas and the tips that keep you hydrated

By Dan Remon · Evidence checked October 2026

There’s a coffee cup on your desk all day. The water bottle is still in the car.

Infused water is the simplest fix I know for that. Fruit, herbs and cold water in a jug, made the night before and waiting in the fridge. It tastes of something, so you drink it, and it puts a glass in your hand where a soft drink used to be.

Ignore the detox claims. Its job is to get water into you. This covers how to make it, 8 combinations to start with, how much water you need and why it matters for a working day.

How to make infused water

To make infused water, wash your fruit, vegetables and herbs, slice them, put them in a glass jug and cover them with cold drinking water, filtered if you have it. Leave the jug in the fridge for 4 to 6 hours, or overnight for a stronger flavour. Slice firm produce like cucumber and apple thinly, halve berries, cut citrus into quarters or wheels and bruise woody herbs to release their oils. Use cold or room-temperature water, never hot. Take the produce out within a day and drink the water within 48 hours.

Infused water ideas: 8 combinations to start with

Start with one fruit and one herb. Once you know what you like, build from there. Each of these is for a 1-litre jug.

• Cucumber and mint. Half a cucumber, thinly sliced, and a handful of mint leaves.
• Lemon and ginger. 1 lemon cut into wheels and 4 or 5 thin slices of fresh ginger.
• Lime and lemongrass. 1 lime and 2 stalks of lemongrass, bruised. Both are easy to find in Bangkok.
• Strawberry and basil. 6 to 8 strawberries, halved, and a few basil leaves.
• Orange and rosemary. 1 orange cut into wheels and 1 sprig of rosemary, bruised.
• Watermelon and mint. A cup of cubed watermelon and a few mint leaves. Melon softens fast, so take it out after a few hours.
• Apple and cinnamon. 1 apple, thinly sliced, and 1 cinnamon stick.
• Blueberry and orange. A handful of blueberries, lightly pressed, and half an orange in wheels.

If it’s the fizz you miss, top the glass up with soda water. That helps when infused water is replacing soft drinks, and sugar and sweeteners: what the evidence says explains why I start there.

Infused water tips: prep, storage and food safety

1. Wash everything, organic or not. Rinse produce under running water and scrub firm produce such as cucumber and melon with a clean brush. The FDA advises against washing produce with soap, detergent or commercial produce wash.¹ Organic is fine if you prefer it. If you can’t get it, don’t let that stop you.
2. Cut to suit the fruit. Firm produce like cucumber and apple releases flavour slowly, so slice it thinly. Berries and citrus are softer and only need halving or quartering. Press a few berries if you want more flavour.
3. Bruise woody herbs, leave leafy ones whole. Press rosemary, thyme and lemongrass with a muddler or the back of a spoon to release the oils. Mint and basil go in as they are.
4. Use a glass jug. If you use plastic, make sure it’s food-safe. Infuser jugs with a central chamber for the fruit are handy, but you don’t need one.
5. Infuse in the fridge. 4 to 6 hours gives a good flavour and overnight gives a strong one. The CDC lists cut fruit as perishable food and advises refrigerating it within 2 hours, or within 1 hour above 32°C (90°F).² In Bangkok, that makes the fridge the default.
6. Take the produce out, then drink it within 48 hours. Same day is best. Citrus holds up longest, and melon turns soft and mushy first.
7. Refill on the same day. If you’re drinking it that day, the same produce will usually flavour 2 or 3 refills.

How much water do you need a day?

The European Food Safety Authority sets an adequate intake of 2.0 litres of total water a day for women and 2.5 litres for men.³ Total water means everything: drinking water, every other drink and the water in your food. EFSA says those values only apply at moderate temperatures and moderate activity levels. The NHS notes that you may need more fluid in a hot environment or when you’re active for long periods.⁴

Water, lower-fat milk and lower-sugar drinks, tea and coffee included, all count towards your daily fluid, according to the NHS. Its practical check is simple: drink enough during the day that your pee is a clear pale yellow. Fruit juice is the one to watch. The NHS limits it to one small 150 mL glass a day, with a meal, because of the sugar.⁴

If your afternoon drink is a soft drink or a sweetened coffee, a jug of infused water is the easiest swap you’ll make. 5 ways to stop sugar cravings covers the rest of that afternoon.

How dehydration affects focus and training

A 2018 meta-analysis pooled 33 studies with 413 participants who were dehydrated by 1 to 6% of their body mass. Dehydration impaired cognitive performance overall, by a small but significant amount. Attention, executive function and motor coordination were all impaired, attention most of all, and the impairment was greater once losses passed 2% of body mass.⁵ For an 80 kg person, 2% is 1.6 kg of water.

Training shows the same direction. A 2015 meta-analysis of 28 studies found that hypohydration cut muscle endurance by about 8%, strength by about 5.5% and anaerobic power by about 6%.⁶

In these studies the deficits were induced on purpose, by methods that varied, so they show what a real deficit costs. They don’t tell you what one extra glass buys. What I take from them is simple. Water is a performance input, the same as sleep and food, so I set it up to happen without a decision. Physiology before strategy.

Make water your Monthly Lever

Knowing you should drink more water has never filled a glass. The fix is to install it.

In the Stealth OS, every change goes in through the Monthly Lever: one change, held for one 28-day cycle until it runs without a decision, with the next cycle stacking on top of it. Water makes a good first lever because it’s small, visible and easy to check. Here’s how to run it.

1. Name it so you can see it. “Drink more water” can’t be checked. “A 1-litre jug of infused water, made the night before and finished by 15:00” can.
2. Set it up the night before. Make the jug straight after something you already do every evening, like setting up tomorrow’s coffee. That’s habit stacking. Keep a bottle on your desk and another in your bag.
3. Check it daily. One line in the Stealth Tracker, the 60-second daily check-in: done or not done.
4. Review on day 28. If it ran on most days, it’s installed. Keep it and choose the next lever. If it didn’t, make it smaller or put the jug somewhere you can’t miss it, and run it again.

How to start

Water is one lever. Find out which one comes first for you.

1. The 1% Scorecard. 8 questions, 2 minutes, free. You get a score out of 100 and the one thing to install first.
2. The Quest. My performance membership, run in 28-day cycles. One lever per cycle, checked daily, alongside founders running the same system. Cancel anytime.
