Pure water, which is not contaminated by chemicals, is essential for a healthy body and mind, according to a new study.
The findings, published in the journal Nature Medicine, suggest water is a “good place to start to find happiness.”
The results are based on a longitudinal study of nearly 1,000 adults.
Participants were asked to answer questions about their health and well being as well as about a variety of environmental factors, such as pollution and climate change.
The participants were asked what qualities they thought made water pure.
Participants were asked how much water they used and whether it was pure.
Some were asked about their own health, and others were asked the same question.
They also were asked whether they were physically active and how often they exercise.
Participants also were rated on their happiness and perceived health by a panel of experts, including health professionals, scientists and a psychologist.
Participants who reported a healthy lifestyle and no pollution were rated the most satisfied.
Participant happiness was lower in areas of pollution than the average, the study found.
Water was also rated as the “best place” to live in, with a negative correlation with happiness.
The findings are the first to show that water can be an important factor in a person’s health, the authors wrote.
“The results from this study support the concept that water may play a role in physical well-function and mental well-disciplines and, potentially, overall well-health,” the authors said in the study.
“In this study, participants’ self-reported health was a predictor of their happiness.”
Water is not a source of pollution, but pollution can cause serious health problems.
People are more likely to suffer from chronic diseases and to suffer severe illnesses, such a heart attack, stroke, kidney failure, cancer, or birth defects.
The pollution is especially harmful to people with certain diseases and conditions, such heart disease, stroke or diabetes.
The Environmental Protection Agency and the Environmental Protection Office of Public Health have said that drinking water is not the most harmful source of greenhouse gases.
Drinking water is good for your health.
And water quality is also a key factor in the health of the human body, the EPA and the EPA said in a joint statement.
“It is also important to note that drinking drinking water may be beneficial to health in general,” the statement said.
“For example, drinking water can help reduce the risk of certain cancers.”
Water’s health benefits are not limited to the human population.
It can be used as an ingredient in products and cosmetics, and it can help in the treatment of some illnesses.
But the most important benefit is the health benefits from water, said Michael Shanks, director of the Water Quality Lab at the University of California, San Francisco.
“There’s no question that water is one of the best sources of natural products and chemicals,” Shanks said.
Water’s value as a “source of happiness” has been debated for years.
A 2010 study published in The Journal of Environmental Health concluded that drinking purified water for 30 days helped improve people’s happiness.
But this was an observational study, not a controlled trial.
Dr. Elizabeth M. Brown, a professor of psychiatry at Columbia University Medical Center, said she was surprised by the new study because it looked at water as a source for happiness.
“In a lot of cases, people think happiness is only a positive thing, but water is very much a source that can really have a negative effect,” Brown said.
Drinkable water can actually be dangerous, Brown added.
“When you’re drinking water, you’re putting chemicals into the water that can affect your health.”
A 2011 review of studies that examined the health effects of drinking water found that drinking tap water had no significant effects on health.
A 2012 study in the Journal of the American Medical Association found that people who drank water had lower levels of blood pressure and other blood markers, lower blood sugar levels and lower cholesterol levels.
The EPA and EPA did not immediately respond to questions about the new paper.
