There Could Be a Dramatic Hidden Impact of Not Having a Regular Bedtime, Study Shows - ScienceAlert

There's already some strong evidence that getting to bed at a regular time is important for healthy living, besides how many hours of slumber we're clocking up in total.

In research involving the direct measurement of the sleep times and moods of 2,115 physicians over the course of their first year of training, scientists found that those with variable sleep patterns were more likely to report lower moods and score more highly for symptoms of depression in questionnaires.

While we can all agree that better sleep habits are good for our overall health, the team behind the new study wants to see more research into how different aspects of sleep hygiene – bedtime, waking up time, sleep patterns, total sleep – affect wellbeing individually.
