What to look for
Insulated vs non-insulated: for cold drinks all day, insulated stainless steel is worth paying for. For room-temperature water to hit daily intake goals, a simple BPA-free plastic bottle works fine. Key features: leakproof, dishwasher-safe lid, wide mouth for ice cubes.
Frequently asked
How much water should I drink daily?
NHS guidance: 1.6 litres (6-8 cups) for women, 2 litres (8-10 cups) for men, in normal conditions. Physical activity, hot weather and illness all increase needs. Urine colour is the best real-time guide — pale straw yellow means well-hydrated.
Are reusable bottles hygienic?
Yes if cleaned regularly. The biggest hygiene risk is the straw or spout — clean weekly with a bottle brush and pipe cleaner. Wide-mouth bottles are easier to clean thoroughly.
