Sun exposure causes cancer and wrinkled skin. The American Cancer Society states that adults and children must use a sunscreen of SPF 15 or higher. Stay out of the sun between 10 am and 4 pm when the sun’s rays are very intense. Do wear protective clothing and hats when working in the sun and utilize sunglasses for eye protection.These thoughts were, and are, so unlike me. I am a very positive person who rarely worries or frets. I am easygoing and generally take everything as it comes, with a smile on my face. I was very disturbed by the dark turn in my personality. I remember reading at that time that second pregnancies are often plagued with unfounded fears and is not uncommon.There are very few sources of fluoride in people’s diets except water or products where it is an additive. The source of the fluoride doesn’t really matter as most inorganic fluorides hydrolyze to form fluoride and bifluoride ion in water. Many toothpastes use stannous fluoride. Many countries add fluoride to salt or even to milk as tooth decay is considered to be a much more serious health risk than fluoride exposure. The exposure from all sources should be kept below 1.0 pm so those who have fluoridate water or salt should not use other fluoridated products or toothpaste. If you are worried about fluoride in you water, there are water filters that remove it from drinking water and it is easy to avoid it from other sources.
