Water is the key to life and the healthiest drink in the world, and it has a variety of benefits that can help maintain a healthy heart, clear skin and good digestion

The healthiest drink in the world is probably already in your kitchen cupboard and it’s not green tea.

Water is widely acknowledged as the most beneficial for our bodies, a fact highlighted in a viral video by YouTube group AsapScience. In the clip, they set out to taste-test what are claimed to be the world’s healthiest drinks. Their reactions to each beverage were captured on camera as they shared their thoughts on the taste and texture of each one, culminating in the healthiest of them all water.

Water is, of course, vital for life on Earth, and humans can’t survive without it for long. It’s needed to keep us hydrated and regulate body temperature, but it’s also crucial for heart health.

As the YouTubers pointed out, it can also aid digestion and keep skin healthy, reports Surrey Live.

But are all waters created equal? That depends on the type of water you choose to drink, because alongside sparkling and still water, there are also flavoured and mineral-infused waters.

According to Klean Kanteen, some types of water are healthier than others, with the company concluding what the healthiest kind of water to drink is.

They explained: “Spring water is considered the healthiest water to drink because it contains essential minerals such as calcium, magnesium, sodium, and potassium. As the name suggests, the water comes from a spring or an underground source. It’s the purest form of water as it’s natural and organic, without any treatment.

“Spring water is among the healthiest waters to drink because it offers several benefits. It is naturally purified from an underground source, which means it is free of harmful contaminants like lead and chlorine. Since it does not undergo added filtration before bottling, it retains the beneficial minerals in the water.”

The Heart Foundation shed light on why water is crucial for your ticker, remarking: “Water is also critical for your heart health.”

They further detailed: “Your heart is constantly working, pumping about 2,000 gallons of blood a day. By staying hydrated that is, by drinking more water than you are losing you are helping your heart do its job.”

When it comes to how much H2O we should be throwing back, the NHS has some clear advice, suggesting that to keep things ticking over nicely we need to consume 68 glasses daily. They say kick off with a glass in the morning and continue at regular intervals during the day and it doesn’t all have to be straight-up water either; low fat milk, sugar-free beverages including low sugar cordials, and even tea and coffee get the green light too.
