On the last Sunday in October, we will set our clocks back an hour, which may temporarily disrupt the sleep patterns of some people.

University of JyväskyläOct 23 2024 Research at the University of Jyväskylä in Finland shows that sleep deprivation impairs learning, especially through the functions of the brain's hippocampus. Even though resetting the clocks can affect alertness, short-term sleep disturbances do not permanently impair our learning ability.

Certain brain phenomena related to long-term memory are most common during sleep. Our interest in studying functions related to the consolidation of memory traces finally led us to examine the hippocampus during the first periods of rest and sleep following learning." Brain activity varies in different stages of sleep Sleep can be roughly divided into two main stages: Rapid Eye Movement sleep and Non-Rapid Eye Movement sleep.

The phenomenon has been studied with the help of several experiments in which people have first been taught various tasks, and then either early night sleep or early morning hours sleep has been disturbed, and after this, the participant's memory performance has been observed. The results have been contradictory, but it seems that both stages of sleep are needed for learning different things.
