There are many normal ways to stay healthy. A good night’s rest will give you energy, Coconut oil will slow down your skin’s aging process, and exercise will keep you slim and fit. But why go through all that trouble when there’s just one simple step to better health? According to 63-year-old Sylvia Chandler, maintaining your best possible health is as easy as drinking your own urine.

In an interview with the U.K.’s Closer Magazine, Chandler attributed her optimal health to drinking a pint of her own urine every day for the last 20 years. She says that “urine therapy” has helped keep her slim, energized, and looking young.

“I have a glass of urine in the morning and another couple during the day,” Chandler told Closer, according to the Daily Mail. “It tastes delicious — it’s a bit like water, but sweeter. I haven’t been to the doctor in a decade. I never get colds, and I’ve maintained my size 10 figure.”

She also says that it’s helpful for healing wounds, and even keeps a bottle of urine aging in her kitchen. Aged urine has stronger healing properties, she says.

The idea of drinking her own urine first came to mind when she opened up her natural health store, Zen, in Birmingham, England. At first, she would dilute it in cranberry juice, but soon enough she was downing glasses of it at least three times a day.

“For nine months before you were born you floated in a combination of your own and your mother’s urine,” she told Truth Juice in 2011. “You drank it, it fed you; it grew your lungs entirely. All of your skin, your bones are made from tiny crystals, which are all formed by urine. Most of us came out perfect with beautiful skin, and it’s only when we’ve lived this toxic life that we get sick. If you came out perfect, it doesn’t matter what you get wrong with you, you can put yourself back to being perfect.”

Although she may not be completely wrong — babies urinate into their amniotic fluid and then swallow it — drinking urine as an adult has not been proven to have any health benefits. “Over the years, many people have claimed health benefits from drinking their own urine, but as far as I’m aware there is no scientific evidence to back-up these claims,” Dr. Rob Hicks, a general practitioner, told the Daily Mail.

Urine is about 95 percent water and five percent waste. The waste consists of excess electrolytes, including chloride, sodium, and potassium, as well small traces of toxins released from the kidneys. While electrolytes allow our cells to conduct electricity, too much can cause dehydration.

“Think about it like drinking ocean water,” Jeff Giullian, a nephrologist at South Denver Nephrology Associates in Colorado, told Popular Science. “It’s going to dehydrate you and do significantly more harm than good.”
