Taking an afternoon nap during the workday may seem like a forbidden concept but experts say it can do wonders for your brain and overall health.
A ‘siesta’, the Spanish word for nap, is a short snooze that is typically taken in the afternoon, often after lunch, and can last up to an hour.
A regular afternoon nap has been a traditional practice in many cultures for centuries and can offer several benefits, including boosting memory, reducing stress and potentially lowering blood pressure.
It can also re-energize you and boost productivity in the after-lunch slump period by reducing fatigue and improving your mood.
Dr Dylan Petkus, a sleep researcher with Optimal Circadian Health told Yahoo: ‘A short nap, around 20 to 30 minutes, can boost acetylcholine (a neurotransmitter that controls memory) levels, enhancing alertness and memory consolidation.
‘It helps you feel more alert and ready to tackle tasks. Be aware, though, that you might feel groggy right after waking up. That said, a quick nap can boost your brainpower for the rest of the day.’
Jenoa Matthes, a travel expert and founder of The Travel Folk who moved to Madrid, Spain nearly five years ago claims that adopting the ‘siesta lifestyle’ has significantly improved her productivity.

She told Yahoo: ‘Coming from the US, where stopping in the middle of a workday to nap seemed practically unheard of, the idea of a siesta was quite foreign to me.
‘At first, I found this disruption to the normal work schedule a bit jarring. After trying the siesta, though, I quickly understood why Spaniards are so devoted to their midday nap.
‘Nothing refreshes me on a hot summer afternoon quite like returning home after lunch, drawing the curtains and lying down for 20 to 30 minutes.
‘The nap also does wonders for my mood and productivity. On days when I don’t get a chance to siesta, I often feel sluggish and find it harder to focus later on.’
And Matthes is not alone in her experience as studies show that taking an afternoon nap can delay cognitive decline and improve memory.
A 2016 study in the Journal of the American Geriatrics Society found people who napped for 30 to 90 minutes had better word recall than those who did not nap or who napped for longer than 90 minutes – indicating they had better memory than their counterparts.
The researchers analyzed data from 2,974 people in China aged 65 and older.
Nearly 60 percent of participants reported napping after lunch for about an hour in a series of self-reported or interview-based assessments.
To see whether afternoon naps are also beneficial for younger adults, researchers involved in a 2018 SLEEP Journal study asked 84 Singaporean students to learn information for about an hour.
They were then asked to take a nap, a break or continue learning for an hour. Once they completed either of the three activities, the students were asked to learn more information and then given a 30 minute test.

Experts suggest only taking nap for 30 minutes to maximize on the benefits
Results showed an hour’s nap helped the participants learn more information than those who spent the same time spent cramming.
The 30 minute test also showed that retention of factual knowledge was significantly greater after an hour spent napping or cramming relative to taking a break.
The study also noted: ‘The nap benefit remained after one week, while cramming no longer provided significantly better retention than taking a break.’
However, experts suggest only taking nap for 30 minutes to maximize on the benefits.
Short naps (20 minutes or less) increase alertness and cognitive performance for up to three hours while longer naps (30 minutes or more) cause us to enter a period of deep sleep during which brain temperature and blood flow to the brain decrease – causing us to be groggy.
Doctors also recommend taking an afternoon nap only between 1 and 4 pm in order to keep our circadian rhythms, the natural processes that regulate our sleep/wake cycle, balanced.
