Scientists reveal that exposure to everyday noise may affect cardiovascular system

Exposure to noise, for example from road traffic, may adversely affect the cardiovascular system. Until now, underlying mechanisms linking noise to elevated cardiovascular risk have rarely been explored in epidemiological studies. Scientists of Helmholtz Zentrum München have now shown that exposure to noise during everyday life influences heart rate variability, i.e. the ability of the heart to adjust the rate at which it beats to acute events.

Intermittent fasting is all the rage, but scientific evidence showing how such regimes affect human health is not always clear cut. Now a scientific review in the British Journal of Diabetes and Vascular Disease published by SAGE, suggests that fasting diets may help those with diabetes and cardiovascular disease, alongside established weight loss claims.
