Concerns about fluoride in drinking water harming brain health or lowering IQ may be overstated. A long-term study published in the Proceedings of the National Academy of Sciences tracked thousands of Americans from their teenage years in the 1950s into old age and found no evidence that fluoride exposure causes harm.
Meanwhile, when it comes to personal care, experts say higher price tags don’t always mean better results. Dermatologists advise focusing on ingredients rather than cost. For example, sulfate-free shampoos are often recommended for gentler hair care, while effective moisturizers should include hydrating components like ceramides and hyaluronic acid, along with sunscreen for skin protection.
Sleep specialists are also urging people to pay attention to something often overlooked: their pillows. Polyester pillows should typically be replaced every one to two years, while down or memory foam versions can last two to three years. Over time, pillows collect dust mites, allergens, sweat, and bacteria, which can lead to discomfort and reduced sleep quality.
