Throughout the day, we receive and retain vast amounts of information by creating memories, but most of that information makes no sense to retain and, for us, brain don’t burden yourself with irrelevant information, at that hour of sleep Storage clean.

In 2018, a study from Cambridge University led by Spanish scientists Ana González Rueda, revealed that when we sleep, neural connections that gather important information are strengthened and neural connections made from irrelevant data weaken until they disappear. According to González Rueda: «Even though the brain has a tremendous storage capacity, maintaining neural connections and activity requires a lot of energy. It is much more efficient to only store what is needed,” says the expert. “Even without storing all the information we receive, the brain uses up 20% of the calories we consume,” he concluded.

Sleeping after studying is very important for human memory consolidation

Experts investigated whether learning complex multiplication tables before bed would benefit memory compared with studying them while awake to understand how sleep affects memory for mathematical operations.

It is recognized that the learning and implementation of mathematics is highly dependent on Storage. For example, there is a close relationship between math achievement and working and short-term memory. The signatories of the article stated that “the ability to correctly recall numerical data from memory – such as multiplication tables – is an important component of mathematical achievement” and added: “Fluent retrieval of numerical data frees up cognitive resources that would otherwise be needed to obtain answers to calculations simple, allowing individuals to focus on the conceptual and strategic aspects of mathematics.”

77 adults aged between 18 and 40 years in the UK participated in the study. Each participant studied complex multiplication problems in two conditions: before going to bed – studying while sleeping – and in the morning studying while awake. Participants complete online sessions in which they learn new complex multiplication problems or are tested on previously studied material. Study sessions include timed and untimed tests.

The main takeaway is the participants they remember better before bed compared to when they do it in the morning. Although participants had different learning abilities, the evening learning condition showed beneficial effects on memory.
