I Heart Water
Too much salt intake is bad for the heart, resulting in enlargement and thickening of the organ and a higher risk of failure. Researchers looked at the balance of salt and water in blood and found that people who stayed well-hydrated had lower risk of cardiovascular disease.
What does it mean to be "well-hydrated"? Researchers translated that to 6-8 cups (1.5-2.1 liters) a day for women and 8-12 cups (2-3 liters) for men.
State of the Air
A new report on the air we breathe from the American Lung Association is -- cough, cough -- not so great. The report covering 2018 to 2020 recorded the most days with "very unhealthy" and "hazardous" air in its 23-year history.
Tracking soot and smog, the analysis said 137 million Americans are exposed to unhealthy levels of air pollution, particularly people of color, who are 61% more likely than white people to live in a county with a failing grade for at least one pollutant and 3.6 times as likely to live in a county with a failing grade for three pollutants.
Air quality has gotten better with reduced emissions from vehicles, power plants and manufacturing, reports STAT, but wildfire smoke and ozone pollution from hotter, drier conditions born of climate change have offset those gains.
Body of Knowledge
To reduce one pound of fat, you need to walk 34 miles. Easier to break it up, though, which breaks down to walking approximately five miles a day seven days a week. Or you could simply reduce your daily calorie consumption by 500 calories.
Hyperglycemia: a fairly well-known term describing high levels of glucose (sugar) in the blood. Hypercalcemia describes excessive concentrations of calcium in the blood. Hyperlipidemia describes high levels of fat.
