Health experts warn daylight saving time changes disrupt circadian rhythms and sleep

As clocks fall back this weekend, sleep scientists and health experts are raising concerns about the twice-yearly time changes disrupting internal body clocks and circadian rhythms. Researchers are particularly warning against permanent daylight saving time, citing risks of darker winter mornings affecting children's sleep and safety during school commutes.

Top claims

▪Lead researcher Josh Neudorf of Simon Fraser University stated that older and younger adult brains responded in opposite ways when subjected to acute sleep loss of three hours.
▪In a Simon Fraser University study, three hours of sleep loss caused decreased brain network connectivity in older adults aged 65 to 75, promoting more efficient modular connectivity across the brain.
▪According to the theory of compensation cited by Simon Fraser University researchers, aging brains compensate for deteriorating sleep quality by reorganizing network connections to maintain cognitive function.
