It’s no secret that water is vital to your health.
In fact, water comprises 45–75% of your body weight and plays a key role in heart health, weight management, physical performance, and brain function (1Trusted Source).
Studies show that upping your water intake may offer many health benefits (2Trusted Source).
However, the amount of water you need is a subject of controversy — and drinking too much can harm your health.
This article examines the benefits and downsides of drinking 3 liters (100 ounces) of water per day.
On July 2, Massachusetts’ Department of Public Health issued an advisory warning that “pregnant women, nursing mothers, and infants should not drink certain brands of spring water bottled by Spring Hill Farm Dairy,” a Haverhill company.
But while the state’s Bottled Water Consumption Advisory was made public on the agency’s website, it was not broadly publicized.
Spring Hill Farm Dairy, which has since shut down, estimated six to seven percent of the state’s population was impacted by the advisory.
Prompted by listener questions, WGBH News asked the state, the bottled water company and retailers what efforts they made to inform the relevant population.
You’ve probably heard it more than once: drinking more water will help you lose more weight. But does water really help weight loss? The short answer is yes. Drinking water helps boost your metabolism, cleanse your body of waste, and acts as an appetite suppressant. Also, drinking more water helps your body stop retaining water, leading you to drop those extra pounds of water weight. What can you do to make sure you’re drinking the recommended eight to ten eight-ounce glasses per day to keep yourself hydrated and encourage weight loss?
Not long ago, Nathan Volpi began wondering about the safety of the tap water that he, his wife and two young children had been drinking for years.
Volpi, a lawyer, had heard worrisome stories from friends and relatives in southeastern Pennsylvania about tainted drinking water found near military bases there. The same contaminants had turned up in wells serving Harrisburg International Airport just across the Susquehanna River from his home in Newberry Township, and he knew of defense facilities in the general area.
“Seeing all these red flags,” Volpi recalled, “I decided to get my water tested to see how it came out.”
You should drink water every day. Most people have been told they should drink 6 to 8, 8-ounce glasses of water each day. That is a reasonable goal. However, different people need different amounts of water to stay hydrated. Most healthy people can stay well hydrated by drinking water and other fluids whenever they feel thirsty. For some people, fewer than 8 glasses may be enough. Other people may need more than 8 glasses each day. If you are concerned that you are not drinking enough water, check your urine. If your urine is usually colorless or light yellow, you are well hydrated. If your urine is a dark yellow or amber color, you may be dehydrated.
If you buy your groceries at Walmart or Target, think again! For instance, tests from the Center for Environmental Health found high levels of arsenic in certain bottled waters. They found arsenic in bottled water brands Peñafiel and Starkey. The bottled water contains higher arsenic levels than tap water. Therefore, they had high enough levels to violate California’s guidelines.
