(HealthDay News) — Though exercise and proper diet are essential to maintaining good health, the body’s basic need for water is often overlooked. Not drinking enough water can be dangerous and have a plethora of negative effects, says Texas Health and Human Services. Your body needs to be hydrated to work properly. Breathing, circulation, body temperature regulation and the senses all rely on sufficient water. Dehydration can also affect your mood, making you cranky, tired or irritable. In fact, sometimes when you feel hungry, your body is actually craving water, the school says.

(HealthDay News) — A lot of people turn to caffeine to get an energy boost in the morning. But there are healthier ways to start the day, says Iowa State University. The school mentions six ways to wake up without coffee: Perform morning stretches, such as head and shoulder rolls. Have a healthy and balanced breakfast. Drink a cold glass of water. Take a cold shower. Splash your face! Start the morning with an upbeat music playlist. Get fresh air and sunlight.

The holiday season can give you real headaches, but you can take action to prevent them, an expert says. To reduce stress, make plans well in advance and know your limits, advised Dr. Bing Liao, a neurologist at Houston Methodist. “The nature of the holiday season already increases stress levels, so finding small ways to reduce schedule stress can help ward off a headache,” Liao said in a hospital news release. “This can mean planning well in advance to avoid the hassle of making last minute travel plans, or deciding not to attend a party at the end of a long day.” Be sure you have an adequate supply or a refill of your prescription medications before the holidays, she advised. Missing doses or cutting back could trigger a headache or even serious side effects. “Don’t binge anything during the holidays — food, alcohol, or television,” Liao said. “We all know how a hangover can affect the brain, but most don’t realize that overeating can also trigger a headache. And having the next day off from work doesn’t mean you should stay up late watching holiday movies. The brain needs the same amount of sleep during the holidays as it does the rest of the year, so stick with your usual bedtime.” Running holiday errands can lead to skipped meals and dehydration, which can trigger…  read on >

Levels of the widely used chemical bisphenol A (BPA) in people’s bodies are much higher than once thought, according to scientists who say they’ve created a more accurate way to measure them. BPA is used in many plastic products, including food and drink containers, and animal studies have shown that it can interfere with hormones. Exposure to BPA in the womb has been linked to growth, metabolism, behavior and fertility problems, as well an increased risk of cancer. The U.S. Food and Drug Administration, however, contends human exposure to BPA is at very low, and therefore, safe levels. The new method developed by researchers and outlined in their study suggests that the measurements used by the FDA and other regulatory agencies underestimate BPA exposure by as much as 44 times. “This study raises serious concerns about whether we’ve been careful enough about the safety of this chemical,” said study co-author Patricia Hunt, a professor in the School of Molecular Biosciences at Washington State University. “What it comes down to is that the conclusions federal agencies have come to about how to regulate BPA may have been based on inaccurate measurements,” Hunt said in a university news release. Co-author Roy Gerona is an assistant professor of medicine at the University of California, San Francisco. He said he hoped the findings would prompt other experts and labs…  read on >

Obese teenagers can have certain brain differences from their thinner peers — changes that might signal damage from inflammation, a new, preliminary study suggests. Using advanced MRI techniques, researchers found that obese teenagers tended to have signs of decreased “integrity” in the brain’s white matter. White matter contains the fibers that connect different areas of the brain. In this case, lower white-matter integrity was seen in a brain region related to emotional control and “reward” seeking. The findings, based on 120 teenagers, are considered preliminary. Experts said it’s not clear what they might mean. But the findings add to evidence linking obesity to certain brain structure differences. Recent studies of middle-aged adults, for example, have found evidence of brain tissue “shrinkage” among those with high levels of body fat — particularly around the belly. One possibility is that excess amounts of body fat directly harm the brain through inflammation, the researchers suggested. In the new study, there was a correlation between decreases in white matter integrity and higher levels of certain inflammatory substances in the blood. Teens with those brain changes also tended to have higher levels of the hormones leptin and insulin. Leptin is involved in appetite control, while insulin regulates blood sugar levels. Dr. Harold Bays is a fellow of the Obesity Medicine Association and medical director of the Louisville Metabolic and Atherosclerosis…  read on >

More Americans have been sickened with E. coli after eating romaine lettuce thought to be grown in Salinas, Calif., federal health officials said Tuesday. Twenty-seven new cases have been reported over the past few days, according to the U.S. Centers for Disease Control and Prevention. That brings the total to 67 across 19 states. In 39 cases, illnesses have been so severe as to require hospitalization, although no deaths have yet been reported. Late Friday, the U.S. Food and Drug Administration issued a warning to consumers to avoid all romaine lettuce grown in Salinas, Calif., due to possible contamination with E. coli bacteria. The goal “is to limit exposure and help prevent additional people from becoming sick,” FDA Deputy Commissioner for Food Policy and Response Frank Yiannas said in an agency news release at the time. “Our investigation has led us to farms in Salinas, California, and while the FDA is sending investigators there to look for the source of contamination, we are updating our advice today to help protect the public health and to help ensure we contain this outbreak,” he said. “Consumers should not eat any romaine lettuce harvested from Salinas, California.” Romaine lettuce harvested elsewhere is thought to be safe to eat, Yiannas added. He added that the latest advisory extends to packaged salads included in a U.S. Department of Agriculture advisory…  read on >

The turkey, stuffing, cranberries, green bean casserole and mashed potatoes on the Thanksgiving table may look tempting, but if you have gastroesophageal reflux disease (GERD) you should proceed with caution, experts say. GERD is often called chronic heartburn or acid reflux. “When it comes to what we eat and drink over the holidays, it is important to remember the saying: everything in moderation,” said Dr. Robert Kavitt, director of the University of Chicago Medicine Center for Esophageal Diseases. A common digestive disorder, GERD occurs when stomach acid flows back into the esophagus, which is the tube that connects the mouth and stomach. It’s important for people with GERD to eat slowly and avoid overeating, Kavitt said. Eating slowly gives you time to feel full, which decreases your risk of overeating. Overeating puts pressure on the lower esophageal sphincter (LES) muscle, a ring-like muscle that acts as a valve between the esophagus and stomach. When that muscle is weakened, acid can flow back into the esophagus and trigger a GERD episode. Eat at least an hour or two before going to bed. It’s more difficult to digest your food when you’re lying down, so eating earlier and staying upright for a bit will allow your food time to break down. Drink more water and limit carbonated beverages and alcohol. “Carbonated beverages and alcohol can cause relaxation…  read on >

Asthma or allergies can put a damper on holiday gatherings. But there are ways you can stay healthy, the American College of Allergy, Asthma and Immunology says. “Everyone wants this time of year to be picture-perfect. But when there are runny noses, itchy eyes and sneezing involved, the picture is less than ideal. There are steps you can take to make your celebrations more fun and joy-filled for the whole family,” said Dr. Janna Tuck, a college spokesperson. Among Tuck’s suggestions: Sample holiday treats with caution because they may contain an ingredient that causes an allergic reaction. If you’re going to parties, let the hosts know what foods you need to avoid, and bring some dishes you know are safe, she said in a college news release. Always carry two epinephrine auto-injectors in case you do eat something with an ingredient that triggers an allergic reaction. Consider hosting a gathering yourself so that you can control the food ingredients. Watch out for smoke from fireplaces and candles, which can trigger an asthma attack. Aerosols, such as air fresheners and artificial snow, as well as potpourri and other scents can irritate already inflamed airways and are best avoided. If you’re traveling for the holidays, be sure to pack all asthma or allergy medications for yourself and your family, including at least two epinephrine auto injectors for…  read on >

(HealthDay News) — Figuring out which nutrition and exercise information is trustworthy may be difficult, says the National Institute of Diabetes and Digestive and Kidney Diseases. The agency debunks these common misconceptions: Bread, pasta and rice are not necessarily fattening. Try to eat whole grains to feel fuller. You do not have to avoid all fats if you’re trying to lose weight. Go for foods with healthy fats, such as avocados and nuts. Dairy products may not be unhealthy. Adults should have three servings a day of low-fat dairy products. Physical activity does not have to be for long periods. You can perform short spurts of activity during the week. Lifting weights will not always make you look “too bulky.” Only intense strength training will build large muscles.

Fear of deportation doubles the risk of high blood pressure in Mexican-born women in farmworker families who live in California’s Salinas Valley, a new study claims. It included 572 women, average age 39, who in 2012-2014 were asked to rate their level of worry about deportation for themselves or others as low (28%); moderate (24%); or high (48%). Researchers linked worry to larger increases in systolic pressure. (Systolic pressure, the top number in a blood pressure reading, measures the force of blood against the arteries when heart beats.) But rates of high blood pressure were not significantly different among women with different levels of worry. In follow-ups conducted in 2014-2016 and 2016-2018, women who were more worried about deportation had a larger initial increase in systolic blood pressure and average arterial pressure, the study found. Among the 408 women without high blood pressure at the outset, those with moderate or high levels of worry were twice as likely as others to be diagnosed with high blood pressure. The study was published Nov. 27 in the Journal of the American Heart Association. “Our findings suggest that concerns around immigration policies and enforcement may have potentially negative impacts on the long-term cardiovascular health of immigrants and their families and community,” lead author Jacqueline Torres said in a journal news release. She’s an assistant professor of epidemiology and…  read on >
