The current pace of life means that many people eat at odd hours, and these displaced hours could have consequences for their memory.
Humans, like many animals, have an internal clock aligned with the daily cycles of light and dark. It is what is known as Cardiac rhtyms.
The rhythm of life in today's society means that these circadian rhythms are increasingly disturbed, and sleep-wake cycles are often interrupted.
How do changes in meal times affect us?
A study in mice found that eating during the hours of the day when you should normally be sleeping causes memory impairment.
Mice are nocturnal animals, so they are normally awake and feed at night and sleep during the day. For the study, the authors acclimatized the mice to do it the other way around, that is, to be awake and eat during the day and to sleep during the night. They were allowed to eat only during the time that they would normally be asleep.
By evaluating the memory of these mice, they found that compared to mice on normal meal times, mice that ate at odd hours showed a significant decrease in memory. These animals with disturbed sleep, who ate at odd hours, also showed altered memories of fearful situations, serious impairments in your ability to remember and one slower learning ability than mice that ate in normal times.
