Don’t wash your hands with hot water – use cold water to save energy and water

More on saving water, from the N.Y. Times:

In its medical literature, the 찬양하세 다운로드. Food And Drug Administration." href="http://topics.nytimes.com/top/reference/timestopics/organizations/f/food_and_drug_administration/index.html?inline=nyt-org">Food and Drug Administration states that hot water comfortable enough for washing hands is not hot enough to kill bacteria, but is more effective than cold water because it removes oils from the hand that can harbor bacteria 민국송 다운로드.

I looked on the CDC and Mayo Clinic websites and found nothing 다운로드. One says use cold or warm water and the other says nothing at all.

This means that switching over to cold water with soap is a reasonable step if you’re looking to conserve water and energy 앱굴림 다운로드.

Why is Dentistry so out of date?

Brushing, flossing, white strips and mouthwash: Thanks for all the help, but your services may no longer be required. The end of the cavity could be upon us 플레이 스토어 앱 다운로드.

UCLA microbiologist Dr. Wenyuan Shi has developed a mouthwash that completely eliminates the most malevolent of the 1,000 species of bacteria that can live in your mouth—after just one use 다운로드. In a clinical study, 12 subjects who rinsed just one time with the mouthwash experienced a nearly complete elimination of the baleful bacteria, Streptococcus mutans 다운로드. Four days after the first rinse, their mouths remained mutans-free.

Shi’s mouthwash is currently being tested by the FDA . If the mouthwash passes that hurdle, it will be the first cavity fighter approved since fluoride 60 years ago 다운로드.

“I actually had no dental training,” Shi recalls, laughing. But once he began teaching, he was struck by how, in a country where we can reduce the risk of heart attacks and diabetes, battle cancer and lower cholesterol, dentistry remained out of date 다운로드. The scientist-scholar resolved to work toward converting dentistry from a surgical model to a medical model.

“Last year in American health spending, heart disease was No 한국영화 무료 다운로드. 1, cancer was No. 2 and dentistry was No. 3,” Shi notes. “We spent about $100 billion. In part, because it’s so old-fashioned. Mechanical removal is still the primary tool.”
