Research from Simon Fraser University suggests that remote learning leads to delayed sleep timing without increased overall sleep duration. Students slept later but did not sleep more, contrary to assumptions that would suggest better time management would lead to improved sleep habits.
A study found that sleeping six to seven hours a night is associated with more favorable heart health, while participants who slept less or more had higher cardiovascular risk scores. Inflammation levels, measured by C-reactive protein, were also higher in those with longer or shorter sleep durations.
