Drinking enough to make sure you're properly hydrated isn't as easy as it sounds, with the wide variety of sodas, juices and hot drinks on the market tempting us away from the simplest but most essential liquid.
For anyone struggling to reach their recommended eight glasses of water per day, TikTok has an answer - the bizarre world of WaterTok, where water is turned into more exciting flavoured drinks like pina coladas or birthday cake.
Brits have been baffled watching Americans concoct these sugar and syrup filled water mixes, leaving many wondering if squash or cordials exist across the pond.

WaterTok has an overwhelming 138million views on TikTok and seems on the surface a fun and harmless way to encourage people to drink more water.
Influencers share their water recipes, putting a variety of powdered flavourings and sugary syrups into giant ice filled cups to create fun flavoured drinks.
As with all trends, there is a specific 1.2 litre tumbler used for WaterTok influencers - the Stanley Quencher, which Brits can pre-order and get their hands on later this month.
In the comments of these water creations, numerous Brits have pointed out that these drinks are just squash (albeit an extreme version) but it appears that our common liquid flavouring is simply none existent for Americans.
Pioneer of WaterTok is Tonya Spanglo, who creates her water of the day videos such as "salted caramel apple water" and "strawberry pina colada water" - with the captions controversially including "#weightloss" and "#healthyrecipes".
While adding flavourings to water might seem like a good idea, making it more appetising to drink, Jess Hilliard, nutritionist at sports nutrition brand, Warrior, has warned against the more extreme flavours.
She said: "This began as an attempt to consume more water throughout the day, however, the trend has now spiralled and encouraged people to create 'water cocktails' such as pina colada and banana split water cocktails.
"Taken at face value, WaterTok seems totally harmless and can actually be a great way to encourage people to keep hydrated. Adding a subtle flavour to water can encourage people who don’t ‘like’ water to drink more.
"This being said, issues can arise when people use sweeteners and colourings that are loaded with sugar and artificial flavours and colours to change the taste of their water.
"Adding sugar to water can cause a spike in blood sugar levels, and then an immediate drop, which can cause fatigue and lethargy. Moreover, adding sugar filled flavours and syrups can encourage weight gain, by adding calories to your diet."
So with all that sugar in your water, you could end up feeling worse thanks to the blood sugar crash later on.
Jess is also concerned about the trend encouraging unhealthy diets for weight loss, with followers replacing food with fancy water.
She added: "WaterTok can also become a danger if people see it as giving us the 'ok' to opt for liquid only diets. Such diets do not enable us to consume sufficient vitamins and nutrients throughout the day.
"Substituting meals for liquid is an unconventional and unsustainable weight loss method, and not one that I would encourage."
Many have jokingly compared WaterTok to Water Zero sitcom Parks and Recreation, which has "300 calories per serving" and the zero in the name "refers to the amount of water in it".
