Why Breaks Improve Your Brain’s Ability to Absorb Information

(SeaPRwire) –   In today’s world, information is more abundant and accessible than ever before. Estimates suggest that Americans consume over 12 hours of media daily, with digital content like TikTok videos and podcasts making up two-thirds of this consumption.

This overwhelming influx of information raises questions about the human brain’s capacity to process such a volume of new input. Contrary to the common belief that more intake leads to more retention—a “more is more” approach to information consumption—research indicates that our brains require regular breaks to effectively process what they absorb.

According to Erin Wamsley, a cognitive neuroscientist at Furman University in South Carolina, periods of “offline states,” where a person’s mind is not actively engaged and attention is free to wander, allow the brain to revisit and process recent experiences.

Much of this processing occurs unconsciously, meaning we are unaware it is happening. However, without these pauses, our ability to recall and understand what we have learned can be compromised. Wamsley notes that people often don’t realize their brain is performing a crucial function when they are idle, emphasizing that this offline processing is a vital component of memory.

Why breaks are so important for the brain

Stimulus-free downtime was once a natural part of life. However, in our current era of constant connectivity with AirPods and autoplay, taking breaks from new content has become increasingly optional. Michael Craig, an assistant professor and memory researcher at Northumbria University in the U.K., suggests that the instant accessibility of everything in today’s world may have led us to forgo the natural rest periods that enable the brain to consolidate new memories.

When researchers like Craig discuss memory “consolidation,” they refer to more than just rote memorization of facts. As we encounter new information—whether from news, interactions with colleagues, or study materials—our minds work to integrate this new data with existing memories. This process allows for meaningful connections, deeper understanding, and the generation of novel insights. The brain also uses downtime to discard information it deems unnecessary. Craig explains that filling all idle moments with stimulating content can deprive our brains of the time and space needed for these essential storage and sense-making functions.

In one study, Craig and his colleagues observed that participants who rested quietly for 10 minutes after a learning task demonstrated significantly better recall of new information, including specific details and the ability to differentiate learned content from similar material, compared to a control group that immediately engaged in another task.

This finding aligns with numerous studies on both humans and animals that show a lack of post-learning rest leads to reduced retention, memory errors, and an inability to learn from past mistakes.

Craig posits that our daily activities influence the fate of new memories. Continuous exposure to new information without periods of rest, which were once common, could negatively impact our ability to form and strengthen new memories.

Furthermore, memory research has identified a “recency bias” that can affect individuals who immediately turn to a device during any free moment.

According to Brad Pfeiffer, a neuroscientist at the University of Texas Southwestern Medical School, memory processes tend to prioritize the most recent information encountered. He illustrates this by explaining that if someone scrolls through TikTok immediately after studying, those videos might be what their memory replays and retains, rather than the study material.

How to take a brain break

While research highlights the benefits of cognitive downtime, particularly after learning or experiencing something significant, for memory and its functions, experts are still determining the optimal duration and nature of these breaks.

Current studies indicate that 10 to 20 minutes of quiet, eyes-closed solitude can enhance memory for recently acquired information. However, Craig suggests that shorter “micro breaks” of a few minutes, or even seconds, might also be beneficial.

Additionally, while research has often focused on sitting or lying down in quiet environments, evidence suggests that low-demand activities like folding laundry or going for a walk could also provide the brain with the necessary low-stimulus downtime for consolidating learned material.

Wamsley believes that the types of activities that support information processing and memory consolidation are individual-specific and depend on what the mind engages in. She notes that using social media to “zone out” with minimal attention could be compatible with memory consolidation. Conversely, she points out that activities requiring deliberate focus and effort, such as meditation or problem-solving, are likely to hinder offline memory consolidation.

In essence, resting the mind involves not only taking a break from engaging content but also stepping away from mental tasks that people undertake during their free time for self-improvement or productivity.

Wamsley criticizes the perception in our 24/7 work culture that any form of rest is unproductive, stating, “That view is false.”

Craig concurs, stating that constant busyness and active mental engagement are known to negatively impact learning and memory, concluding, “Sometimes less is more.”
