Going to sleep between 10:00 and 11:00 pm is associated with a lower risk of developing heart disease compared to earlier or later bedtimes, according to a study published in European Heart Journal – Digital Health, a journal of the European Society of Cardiology (ESC).
“The body has a 24-hour internal clock, called circadian rhythm, that helps regulate physical and mental functioning,” said study author Dr. David Plans of the University of Exeter, UK. “While we cannot conclude causation from our study, the results suggest that early or late bedtimes may be more likely to disrupt the body clock, with adverse consequences for cardiovascular health.”
While numerous analyses have investigated the link between sleep duration and cardiovascular disease, the relationship between sleep timing and heart disease is under-explored. This study examined the association between objectively measured, rather than self-reported, sleep onset in a large sample of adults.

I would love to amend our sleeping arrangements. Presently we go to bed around 8:30 pm and get up at around 3:30 am.

Thanks, Paul. You are doing a good job on getting 7-1/2 to 8 hours a night. Well done. I agree that 3:30 is an early start though.

We are doing our best to move the whole sleeping time to nearer 9pm but we also have two dogs that need to pee every few hours and it’s getting them to sleep a little later is also a challenge.

I have puppy pads for my dog so I can take her for a final walk at 5:00 PM and not worry if she needs to go at night. Her kidneys are failing now, so she drinks a lot of water and pees often. I used 24X36 inch adult diapers for the pads.

I must admit that that has been on my mind recently; getting diapers for the dogs. Thanks.
