Napping Daytime Rest as a Health Booster
Is there a "best" time of day to nap?
Nonetheless, the time of day we sleep is important, says Dr Stanley, who suggests that after lunch is often a good time to catch forty winks. "You've just had your lunch, you've had all the digestive hormones and things like that and so, therefore, you get what we call a post-prandial dip, which is like a post-lunch energy crash." Indeed, Dr Stanley says there is scientific evidence to suggest that a post-lunch nap is beneficial.
In addition, "it was also the way that most of the world used to live. They would have a big lunch and have a siesta afterwards." In the UK, he thinks workplaces should embrace this. "There is a big company in London where they have sleep pods and they actively encourage people, if they're tired, to go and have a 20 minute nap. And then they get on with their job, they're much more productive in the afternoon."
Napping can be healthy for our hearts
In contrast, we are all aware of the potential dangers of being sleep deprived, and the importance of getting a good night's rest. Conversely, not getting enough sleep can affect our blood pressure and our mental health. However, we may not be aware of the health benefits of a daytime snooze, which have been highlighted in recent years.
A study published in the journal Heart in February 2023 found that regular daytime naps were associated with lower blood pressure. Specifically, the study of over 3,000 people found that those who napped regularly had blood pressure readings that were, on average, 5mmHg lower than those who did not nap. The researchers also found that people who napped more frequently had lower blood pressure than those who napped less often.
The study's lead author, Dr Manolis Kallistratos, said: "Midday sleep appears to lower blood pressure levels at the same magnitude as other lifestyle changes. For example, salt and alcohol reduction can bring blood pressure levels down by 3 to 5 mmHg." The researchers suggested that daytime napping may help to reduce stress and improve cardiovascular health.
Nap and cognition
Furthermore, napping has also been linked to improved cognitive function. In particular, a study published in the journal Nature Neuroscience in 2010 found that a 60-minute nap improved memory performance.
The study participants were asked to learn a list of words and then take a nap. Those who napped performed better on a memory test after the nap than those who did not nap. The researchers suggested that napping may help to consolidate memories and improve cognitive function.
Nap and creativity
Additionally, napping has also been linked to increased creativity. A study published in the journal Personality and Social Psychology Bulletin in 2009 found that people who took a 90-minute nap were more likely to come up with creative solutions to problems than those who did not nap.
The researchers suggested that napping may help to break down mental blocks and allow for new ideas to emerge. In light of this evidence, it seems that napping is not just for the tired or lazy. It is a natural and healthy way to improve our physical and mental well-being. So, the next time you feel the urge to take a nap, don't fight it. Embrace it and enjoy the benefits that it can bring.
How long should a nap be?
Of course, everyone is different and what works for one person, won’t work for another. However, generally speaking, Dr Stanley says a short 20 minute nap is the "gold standard".
"You get the maximum benefit for the minimum amount of sleep and you wake up feeling refreshed and bright," he explains. "Anything more than that and you start going into a deeper sleep, and then you need to be sleeping for about two hours to get the full benefit of that."
He also stresses that, even if you don't actually fall asleep, just lying down and closing your eyes is good for you. "Even if you only just drift off, you still get about 50% of the benefit just by closing your eyes and lying down quietly. It's really good for you."
Who benefits most from naps?
While anyone can benefit from a nap, certain people may find them particularly helpful. For example, shift workers, new parents, and people with sleep disorders may find that naps help to improve their alertness and cognitive function. Similarly, older adults may also find that naps help to improve their sleep quality and reduce their risk of falls.
Who should avoid napping?
However, napping is not for everyone. People who have trouble sleeping at night should avoid napping, as it can interfere with their nighttime sleep. People with certain medical conditions, such as insomnia or sleep apnea, should also talk to their doctor before napping.
Tips for napping
If you are considering taking a nap, there are a few things you can do to make the most of it. Firstly, find a quiet, dark place where you won't be disturbed. Secondly, set an alarm for 20-30 minutes so that you don't oversleep. Thirdly, avoid caffeine and alcohol before napping, as they can interfere with sleep. Finally, try to nap at the same time each day so that your body gets used to it.

Napping and cultural differences
Napping habits and practices vary across cultures. In some cultures, such as Spain and Greece, napping is a regular part of daily life. In Spain, the siesta is a traditional afternoon nap that is often taken after lunch.
In Greece, the mesimeri is a similar tradition. In other cultures, such as the United States and the United Kingdom, napping is less common. However, napping is becoming more popular in these countries, as people become more aware of the benefits of sleep.
Napping and the workplace
Napping in the workplace is a growing trend. Some companies are providing nap pods or quiet rooms for employees to use during their breaks. Other companies are allowing employees to take short naps at their desks.
There is evidence to suggest that napping in the workplace can improve employee productivity and morale. A study published in the journal Sleep in 2008 found that employees who took a 30-minute nap were more alert and productive than those who did not nap.
The future of napping
As more and more research highlights the benefits of napping, it is likely that napping will become even more popular in the years to come. We may see more companies offering nap pods and quiet rooms for employees, and we may even see schools introducing nap time for students. Napping could also become a more common part of healthcare. Doctors may recommend naps to patients with certain medical conditions, and hospitals may provide nap rooms for patients and staff.
Napping and technology
Technology is also playing a role in the growing popularity of napping. There are now a number of apps and devices that can help people to track their sleep patterns and optimize their naps. These apps can help people to identify the best time of day to nap and the ideal nap length.
Napping and the environment
Napping can also be a sustainable way to improve our well-being. Unlike other activities that require energy and resources, napping is a low-impact way to reduce stress, improve cognitive function, and boost creativity. By taking a nap instead of reaching for a sugary snack or a cup of coffee, we can reduce our environmental footprint and improve our health at the same time.
Napping and social connection
Napping can also be a social activity. In some cultures, people gather together for a group nap, known as a siesta or mesimeri. This can be a way to connect with others, relax, and recharge.
Napping and self-care
Napping is an important part of self-care. By taking the time to rest and recharge, we are investing in our physical and mental health. Napping can help us to be more productive, creative, and resilient. In a world that is constantly demanding our attention and energy, napping is a simple and effective way to take care of ourselves. Napping is a natural and healthy way to improve our physical and mental well-being.
It is a low-impact, sustainable, and social activity that can help us to reduce stress, improve cognitive function, boost creativity, and connect with others. Whether you are a shift worker, a new parent, an older adult, or simply someone who needs a little boost, napping can be a valuable tool for improving your health and well-being.
Famous nappers
Throughout history, many famous people have been known for their napping habits. Winston Churchill, for example, famously took a nap every afternoon, believing that it helped him to be more productive. Other famous nappers include Albert Einstein, Thomas Edison, and Leonardo da Vinci. These individuals understood the importance of rest and rejuvenation, and they used napping as a tool to enhance their creativity and productivity.

Napping in the animal kingdom
Napping is not just a human behavior. Many animals also take naps, including cats, dogs, and even some primates. Napping is thought to be an evolutionary adaptation that allows animals to conserve energy and avoid predators. For example, cats are crepuscular animals, meaning that they are most active at dawn and dusk. They often take naps during the day to conserve energy for their hunting activities.
Napping and the future of work
As the nature of work continues to evolve, napping may become an even more important part of our daily routines. With the rise of remote work and flexible schedules, people are increasingly able to take naps during the day. This could lead to a shift in workplace culture, where napping is seen as a normal and healthy part of the workday.
Napping and the economy
Napping could also have a positive impact on the economy. Studies have shown that napping can improve employee productivity and reduce healthcare costs. By encouraging napping, businesses could potentially save money and improve their bottom line.
The science of napping
Scientists are still learning about the science of napping. However, research has shown that napping can have a number of positive effects on the brain and body. For example, napping has been shown to improve memory, creativity, and cognitive function. It has also been shown to reduce stress, lower blood pressure, and boost the immune system.
The future of Nap research
As our understanding of sleep and its importance continues to grow, we can expect to see even more research on the benefits of napping. This research could lead to new insights into how naps affect our brains, bodies, and overall well-being. We may also see the development of new technologies and strategies to help people optimize their naps and get the most out of this natural and healthy form of rest.
Napping and mental health
While napping has been primarily associated with physical health benefits, recent research suggests that it may also play a role in mental health. Studies have indicated that regular napping could be linked to a lower risk of depression and anxiety. The restorative power of sleep, even in short bursts, can help regulate emotions and improve mood. Further research in this area could lead to new approaches in mental health care.
Napping and children
Napping is not just for adults. Children, especially younger ones, also benefit greatly from naps. Daytime sleep is crucial for their development, helping with cognitive function, memory consolidation, and emotional regulation. As children grow, their nap needs change. While toddlers might need two naps a day, older children might only need one or none at all. It's important for parents and caregivers to be aware of these changing needs and adjust nap schedules accordingly.
Napping and the elderly
As we age, our sleep patterns naturally change. Older adults often find it harder to sleep through the night and may experience more daytime sleepiness. Short naps can be a helpful way to supplement their nighttime sleep and improve overall well-being. However, it's important for older adults to avoid long or late-afternoon naps, as these can interfere with their nighttime sleep. It's best to keep naps short (20-30 minutes) and schedule them earlier in the day.
Conclusion
Napping is not just a guilty pleasure or a sign of laziness. It's a powerful tool that can enhance our physical and mental health, boost our creativity, and improve our overall well-being. Whether you're a busy professional, a student, a parent, or a retiree, incorporating short naps into your routine could be one of the simplest yet most effective ways to take care of yourself.
As science continues to uncover the many benefits of napping, it's time to embrace this natural and restorative practice. So, next time you feel that afternoon slump, don't hesitate to give in to the urge for a quick snooze. Your body and mind will thank you.
