• A recent study suggests that even a short afternoon nap may help your brain recover and improve learning ability.
• The researchers note that sleep can help regulate excessive brain activity.
• While afternoon naps may offer benefits, there are potential negative effects to consider, such as disrupted nighttime sleep and cardiovascular issues.

Your brain is constantly active during the day. New impressions, thoughts, and information are all being processed. This helps to strengthen the connection between nerve cells or synapses.

A small new study published in NeuroImage suggested that even a short afternoon nap can help your brain recover and improve your ability to learn.

“The study was well designed, and I like it because it helps reinforce the concept that sleep is not just a passive activity where the brain is ‘resting’,” said Vernon Williams, MD, sports neurologist and founding director of the Center for Sports Neurology and Pain Medicine at Cedars-Sinai Orthopaedics in Los Angeles, who was not involved in the study.

“Sleep (even brief naps) does more than simply reduce fatigue. There is a measurable effect on brain physiology,” Williams told Healthline.

The findings show that a nap may be enough to reorganize connections between nerve cells, allowing your brain to store new information more efficiently. Up until now, this was something that was thought to only occur after a full night’s sleep.

This new study found that short sleep periods can relieve your brain and return it to a state of readiness to learn. This process may be particularly beneficial for those with a high workload.

“Our results suggest that even short periods of sleep enhance the brain’s capacity to encode new information,” Christoph Nissen, professor and chief physician at the Department of Psychiatry, University and University Hospital of Geneva (HUG), Switzerland, and member of the research team, said in a press release.

Naps help regulate excess brain activity

The strengthened synaptic connections that come from the brain’s activity during the day are an important neural basis for the learning process.

However, the researchers note that they can also lead to saturation. This can decrease the brain’s ability to learn over time.

Sleep can help to regulate this excessive activity without losing important information.

“The study shows that this ‘synaptic reset’ can happen with just an afternoon nap, clearing space for new memories to form,” Nissen said in a press release.

Short nap boosts brain power

The study observed 20 healthy adults, with an average age of 25, who either napped or stayed awake on two afternoons. For those who took a nap, it lasted an average of 45 minutes.

Direct measurements of synapses in healthy humans are not possible. Instead, the research team used established, noninvasive methods, such as transcranial magnetic stimulation (TMS) and EEG, to draw conclusions about the strength and flexibility of synapses.

The results of the testing showed that after a nap, synaptic strength in the brain decreased.
