▶ Ahead of World Sleep Day tomorrow, Anastasia Mirai explores whether a midday nap can counter the effects of not getting a full night’s rest
Do you find yourself feeling drowsy after your first cup of coffee wears off come mid-morning? Rest assured, you’re not alone. The National Sleep Foundation in the United States has highlighted that coffee is the most popular drug in the world, while the Centre for Disease Control and Prevention has proclaimed insufficient sleep a public health epidemic.
Given how many adults struggle to get a full night’s sleep these days, awareness-raising campaigns such as World Sleep Day – which falls tomorrow – have become increasingly necessary to tackle this so-called epidemic. “Time and again, sleep medicine professionals and researchers came up against the belief that sleep was not [being prioritised] enough in personal health and well-being … coupled with society’s 24/7 flow,” says the World Sleep Society, which created World Sleep Day, in its mission statement. “The founders of this awareness event aim to celebrate the importance of healthy sleep.”
According to the organisation, 46 per cent of sleep-deprived individuals from the sample groups it has monitored reported making mistakes at work, or needing to skip part of, or a whole work day, to make up for their poor sleep. “Many people sacrifice sleep for other pursuits, but what they don’t always realise is that sleep facilitates learning, memory, creativity, problem-solving and productivity,” says Sarah Rasmi, a psychologist and founder of Thrive Wellbeing Centre.
Could a midday nap be the answer to getting through each day with energy and enthusiasm? Historically, the afternoon siesta is synonymous with Spain and Latin American nations, while Italians take their riposo and Greeks their “hours of popular quiet”. The post-lunch snooze also dates back to ancient Islamic tradition. “The practice was recorded in Islamic law and was also written about in the Quran,” the experts at the National Sleep Foundation say on the organisation’s website. Typically, businesses would close for between two and four hours, and working hours resumed once the midday heat had dissipated.
In modern times, the Japanese have reintroduced the trend, bringing it right to the workplace. Karoshi, the term for death by overworking, is considered a legitimate cause of mortality in the sleep-deprived nation. Japan is infamous for having the longest working hours in the world, and many employees take to sleeping at their workplaces to catch up on the rest their bodies need, while employers are turning a blind eye to those sleeping on the job. Inemuri, which essentially means sleeping while present, is the term given to those who nap at their desks or even through meetings, and it is perceived not as laziness, but quite the opposite.
In fact, daytime naps are so on-trend in Japan, that for World Sleep Day, coffee conglomerate Nescafe will open a cafe specially designed for people who want to catch up on their sleep at any hour of the day. Located at Oimachi in Tokyo, the space will offer customers a decaffeinated coffee before they bed down (on mattresses that range from soft to firm). Naps can last between 30 and 180 minutes, and guests are offered a fully charged, caffeinated coffee upon waking. In the western world, Silicon Valley is also welcoming our need for naps, with companies such as Google installing sleeping pods in its offices for staff who need a little R&R between tasks and meetings.
Dr Irshaad Ebrahim from the London Sleep Centre in Dubai says: “As a general rule, we should not need to sleep at any other time other than the designated nocturnal sleep period.” He suggests that the first course of action for anyone struggling through the day should be to assess their environment and check they’re practising good “sleep hygiene” at night, as our need to nap, he says, is either linked to the fact that we are not sleeping an adequate amount for our bodies to function at 100 per cent, or because our sleep quality is not good enough.
The Better Sleep Council suggests that babies need 16 hours of sleep per day, children between three and 18 need up to 10 hours, adults between 19 and 55 need eight hours, and those over 65 need just six hours per night. However, myriad studies and sleep experts have concluded that every individual has different needs when it comes to sleeping.
“In our smartphone-driven society, the demands of our daily lives inevitably results in one of the two Qs – quantity and quality – not being fulfilled,” says Ebrahim, conceding that a “well-calculated” midday nap may well be beneficial in both these cases. He explains that our first deep-sleep phase usually
starts within five to 10 minutes of falling asleep. This can actually be the most restorative part of our sleep cycle, because it’s when our growth hormones are active.
“A 20 to 30-minute nap should get you enough restoration to gain a second wind. But any more than this will result in you entering the deepest sleep stage, which is generally difficult to rouse from,” he explains.
In other words, a midday snooze may well help you to get through each day with energy and enthusiasm, but a long, deep-sleep-inducing nap could have a detrimental effect, leaving you feeling more out of sync than before.
