A serving of chilled water is best for quenching your thirst. The idea of sipping on lukewarm water which has been stored in your refilled Evian bottle isn’t so appealing. Regardless of the type of bottle you’re drinking from, hydration is key. But, to really enjoy your daily water intake and keep your liquids stored at the temperature you want them, you need one of the best insulated water bottles.
You might be wondering if you’re really the kind of person who should have an insulated water bottle. In fact, you might have even looked at others who have one already and turned your nose up. Let us enlighten you and explain why an insulated water bottle is one of the best investments we can all make in 2021.
- Hydration – It may seem obvious but so many of us are guilty of not drinking the recommended amount of water. In the same way that buying a well-designed, quality journal can help us to keep track of our thoughts, meetings and to-do’s, an insulated water bottle is one of the best ways we can encourage ourselves to drink more water and to keep track of how much we’ve drunk, too.
- Hygiene – You’ll find the best insulated water bottles are made from stainless steel. It’s the ideal material to bring to life the double or tripled-walled designs which enable water bottles to keep hot drinks hot and cold drinks cold. It’s also often certified to food-grade standards which is particularly important for hygiene in recent times as a result of Covid-19.
- Sustainability – Though they come with a greater price tag than single-use water bottles, the one-time investment in an insulated water bottle can be very cost-efficient within a couple of weeks. Not only is this great for the sustainability of your bank account, but it’s also a fantastic way to encourage a greener planet and help to avoid single-use plastics.
We’ve rounded up the best 12 insulated water bottles available to order on Amazon. Within a few days of owning one of these, you’ll be wondering why you didn’t have one sooner. They’ll also become your go-to gift for birthdays or Christmas, as they are something everyone can benefit from.
