People who are genetically predisposed to be "early birds" only take a few days to adjust to time changes as a result of daylight savings. Night owls can take over a week to adjust to the time change.
Chronobiologists warn changing to daylight savings can have serious effects on both brain and general health. The change in time during spring was linked to a 24% increase in severe cardiovascular events in women. Researchers also noted the sudden change in time alters circadian rhythms, reduces the production of natural melatonin, impacts cognitive function, and may also foster tumor growth.
A new study reveals an increase in depression diagnosis in Denmark following the transition from Daylight Savings time to standard time.
