It can help the body respond to dangerous or stressful situations by speeding up the body’s heart rate to deliver more…
Sleeping less than five hours a night is associated with a 74% raised risk of developing peripheral artery disease (PAD) compared with seven to eight hours, according to a recent study published in the European Heart Journal. “Insufficient night-time sleep and daytime napping have previously been associated with a raised risk of coronary artery disease which, like PAD, is…
As a four-day work week is trialed in countries globally, health researchers say they’re “all in” when it comes to a long weekend, especially as research from the University of South Australia shows that the extra time off is good for our health.
