We’re all aware that drinking water is essential for maintaining good health and hydration, but just ‘how much’ is often a topic of debate. Now, scientists may have the answer.
A new study from the University of California analysed data from 18 randomised clinical trials to better understand how increasing water intake affects various health issues, including headaches, infections, blood glucose levels, and even weight loss. Most strikingly, they claimed that more water is linked to shedding pounds, with study groups experiencing between ‘44% to 100%’ greater losses than control groups.
This was particularly true when participants drank six cups of water per day, while fewer ‘nephrolithiasis events’ – or kidney stones – were reportedly linked to consuming around eight cups daily. “For such a ubiquitous and simple intervention, the evidence hasn’t been clear and the benefits were not well-established, so we wanted to take a closer look,” said senior and corresponding author Benjamin Breyer.
“The amount of rigorous research turned out to be limited, but in some specific areas, there was a statistically significant benefit. To our knowledge, this is the first study assessing the benefits of water consumption on clinical outcomes broadly.”
The NHS currently advises that individuals should aim for six to eight glasses of ‘fluid’ daily, with the amount increasing for those who are pregnant, physically active, unwell, or residing in warmer climates. While water is indeed a beneficial fluid, the health service also includes low-fat milk, sugar-free drinks, and even tea and coffee under this umbrella.
“We also get some fluids from the foods we eat. Learn why staying hydrated and reducing alcohol intake is important for your health.” The US-based team also pointed out potential benefits of increased water consumption for migraine prevention, urinary tract infections (UTIs), diabetes management, and hypotension.
Though, they cautioned that evidence ‘quality and quantity’ was limited, while stating that a ‘one size fits all’ approach to glasses per day isn’t always ideal.
Breyer continued: “We know that dehydration is detrimental, particularly in someone with a history of kidney stones or urinary infections. On the other hand, someone who suffers from frequent urination at times may benefit from drinking less. There isn’t a one size fits all approach for water consumption.”
