We might want to start here – clocks going back or forward will always mess with our heads. Just as it seeps into the unconscious, the reminder that we have to adjust our clocks always seems to make a comeback.
The research surrounding this phenomenon varies quite a bit, with many studies taking an issue with ‘Daylight Savings Time’.
One 2016 study has highlighted how the act of winding clocks back and forth coincides with higher than usual stroke rates. The study found that stroke rates were 8% higher than usual in the two days following clock changes.
This is due to DST transitions reportedly disrupting out circadian rhythms. Another 2021 article also points to negative impacts of sleep patterns of various test subjects (duh!).
Another 2001 study pinpointed an increase in traffic accidents and overall incidents in the US following the change in clocks. The increase was not noted in the days following the immediate change.
Meanwhile, a neurologist revealed in a 2022 ‘The Conversation’ editorial that even having exposure to light later into the evening delays the brain’s release of melatonin, the hormone promoting drowsiness.
Daylight Savings Time has a history dating back to the two world wars, making a massive comeback into Europe after WWII. However, even ancient civilisations like the Romans adjusted water clocks to adjust schedules according to solar time.
