The B2V Memory Observatory reveals what really happens in our brain during the summer: the role of the default mode network, the importance of mental wandering and the sometimes little-known effects of hyperconnection on our memory.
When you think you’re doing nothing, the brain continues to work
Lying on a beach, sitting in a garden, sitting facing a landscape that you look at without a specific objective… These moments can give the impression of a complete stop. Yet inside, the brain never stops.
Even when we are not engaged in any task, it remains particularly active. “Even lying in a hammock with your eyes closed, the brain still consumes almost 20% of the body’s total energy, only 5% less than when it is used to solve a problem.recalls the B2V Observatory of Memoirs.
This activity relies in particular on the default mode network, a set of brain regions that activates when the mind is no longer focused on a specific mission.
It is this network that allows the brain to wander, make connections, revisit memories or even imagine the future. It participates in autobiographical memory, the one that constructs our personal history and our identity.
In other words, these moments when we think we are “doing nothing” can be moments when the brain is doing particularly elaborate work.
Vacations help the brain store our memories
After a year full of information, demands and decisions to make, the brain must sort things out. The summer slowdown would create favorable conditions for this consolidation. By freeing itself from the constant flow of information, the brain could better integrate what has been experienced and learned over the previous months.
The default mode network, often associated with daydreaming, plays a vital role in this process. It is linked to personal memories, but also to projects and the understanding of others.
This mechanism explains why an idea can arise in the shower, during a walk or during a moment when the mind wanders. When attention is no longer fully engaged by immediate tasks, the brain can make new connections.
Rest is therefore not a void. It can become a space for mental reconstruction.
No need to go far to truly disconnect
Contrary to popular belief, it is not necessary to go to the other side of the world for several weeks to give the brain a beneficial break.
According to the B2V Observatory of Memoirs, “duration is not the deciding factor: it is the quality of the disconnection that counts”. Short regular breaks, a few hours without demands several times a day, can already allow the brain to change pace.
A hike, a craft activity, gardening, painting or simply a moment to let your thoughts drift can promote this particular mental state.
These activities have one thing in common: they take attention away from the continuous flow of screens and give space to sensations, movement and creativity.
Too many screens, a silent obstacle for memory?
If calm seems beneficial, hyperconnection could on the contrary disrupt certain essential mechanisms.
Notifications, messages, constant requests: the brain must constantly interrupt its activity to respond to new information.
According to the B2V Observatory of Memoirs, “hyperconnection disrupts sleep quality, increases stress and fragments attention. Three factors directly harmful to memory”.
The problem isn’t just screen time. It is also the permanent fragmentation of attention, which prevents the brain from fully carrying out its work of consolidation and projection.
Three simple reflexes to give your brain a real vacation
Memory research ultimately outlines a simple idea: the brain needs space.
The B2V Memories Observatory offers three accessible habits:
- Activate your senses rather than multiplying screens : walking in nature, tinkering, gardening or creating allows you to mobilize the body and creativity;
- Allow yourself to wander : looking at a landscape, letting the mind wander, not trying to optimize each moment can help the brain consolidate information;
- Mute notifications : each interruption avoided becomes an opportunity to regain mental clarity and perspective.
Finally, vacations would not just be a break in our diaries. They could be a precious moment when the brain slows down to rebuild itself better.
Sometimes the best way to move forward is to just give him some silence.
