A study finds that children ages 3 to 7 who don't get enough sleep are more likely to have problems with attention, emotional control...
Rapid blood pressure drops in middle age linked to dementia in old age
Middle-aged people who experience temporary blood pressure drops that often cause dizziness upon standing up may be at an increased risk of developing cognitive...
Increasing minimum wage would reduce teen pregnancies
A $1 increase in the minimum wage would likely reduce the U.S. adolescent birth rate by about 2 percent, according to new Indiana University...
