My number one tip: get a container that you love!
The most important thing I can say is to get a container from which you love drinking. Although it may be difficult to transport it out of the house, I adore my 32oz clear mason jar. I ordered a few of them on Etsy, and they each came with a lid with straws that fit through. Over the summer, I frequently would drink over 100oz of water, thanks to that contraption.
Two: put something yummy in there
I like to add pure lemon juice into my cold water. Other times I will add orange juice or a small amount of kombucha (shown in the picture is a small amount of GT’s Winter Edition Pure Love Kombucha added to my water). I like the taste of these three options, and it makes the water go down easier. As a bonus, fresh fruit juice adds electrolytes to water! I also know a few people who prefer infusing their water with flavors from whole fruit slices.
It is important to note, though, that this is not an invitation to add artificial sweetener or anything to change the water. Those may dehydrate you, regardless of the other negative impacts of the chemicals in the additive.
Three: Push yourself to make it a habit
One of the hardest parts about learning to drink more water is making it a pattern. The most challenging part, for me, is to keep drinking water while I am out and about. I always recommend bringing a water bottle with you wherever you go. If I carry around the extra weight from the water in my bag, then I feel a much stronger need to drink from it to make it worthwhile.
When I hike or go backpacking, it is difficult to carry anything but plastic water bottles. I try to avoid the extra weight and the possibility of breakage that comes along with metal and glass. I always hike with at least one other person, so I consistently make sure we are holding each other accountable (ask my friends who spent a week white water rafting with me).
