Hard exercise and sleep deprivation could be bad news for the heart
Young men trained intensively with and without curtailed sleep. A new study shows that with too little sleep, they secreted more of a substance that is a biomarker for potential future heart disease. But the study has major weaknesses, says researcher Stein Ørn.
Live normally despite a hole in heart
Children born with a hole in the wall between heart chambers are often viewed as sickly or feeble. But a new study shows that kids with this relatively common congenital heart defect are just as healthy as other children. A researcher claims we are doing them a disservice by pathologising them.
