Going to bed just one minute later than normal increase chance of heart disease, research finds – The Sun
GOING to bed just one minute later than normal can increase your risk of heart disease.
Experts found a disrupted routine of sleeping between one and 30 minutes later hiked resting heart rate (RHR).
That is a risk factor for cardiovascular disease and heart health problems.
The later people went to bed, the higher the increase in RHR.
Heart rates remained raised throughout the night and into the next day.
Even going to bed more than 30 minutes earlier had a negative effect.
But RHR levelled out during sleep after earlier bedtimes.
US researchers used data from fitness trackers worn by 557 university students for four years.
Normal bedtimes were defined as the one-hour surrounding a person’s average sleep time.
Dr Nitesh Chawla, from Indiana’s University of Notre Dame, said: “If you’re not going to bed at the same time each night, your resting heart rate increases while you sleep, and into the next day.
“For shift workers and those who travel frequently, getting to bed at the same time each night is a challenge.
Establishing a healthy bedtime routine is obviously step number one.”
