The Power Nap – A Secret Health Weapon

The Power Nap  – A Secret Health Weapon

The Power Nap And The Yo-Yo

A power nap and a yo-yo don’t have much in common at first glance but trust me, in this case they do.

One of my most prized possessions when I was in primary school was my Coca-Cola Yo-Yo.  Complete with the original string, this item is now vintage.  So, it was with great excitement that I set out to meet and interview the 1960 State Yo-Yo Champion, Barry Marshall from the infamous West Australian mining town of Kalgoorlie. 

Every Saturday, Barry competed in local competitions and as State Champion was the envy of his mates when rewarded with boxes of the much sought after Coca-Cola. His location and skill-sets have changed over the years and the stakes much higher but this man is still winning prizes.

An Important Discovery

Professor Barry Marshall is an Australian Physician, Nobel Prize laureate in Physiology or Medicine and Professor of Clinical Microbiology at the University of Western Australia.  After decades of the medical fraternity believing that ulcers were caused by stress, spicy foods and too much acid, Marshall and Robin Warren showed that the bacterium Helicobacter pylori (H. pylori) is the cause of most peptic ulcers. This discovery has provided a breakthrough in understanding a causative link between Helicobacter pylori infection and stomach cancer.

The meeting of these two physicians was a true pivotal moment for science.  Warren had become aware of the existence of a unique curved bacteria, Helicobacter Pylori and he invited Marshall to pursue this research together.  In 1984 after several years of research, rejection and criticism from medical researchers, Marshall decided to take matters into his own hands and used himself as a guinea pig.  Without discussion, most notably with the ethics committee, Marshall drank a Petri dish containing cultured H. pylori, expecting to develop perhaps years later, an ulcer.  

This happened just three days later. The infection was successfully treated with antibiotics and the rest is history. It was certainly an unusual method of proving a point but Professor Marshall decided that it was easier to ask for forgiveness rather than get permission!

Nowadays, these types of ulcers are detected by more traditional methods via breath tests, which were also developed by Professor Marshall.

Power Nap – The Most Important Tool

This award-winning scientist rates sleep as his most important performance-enhancing tool and knows that he needs eight quality hours per day. Marshall spends four to six months of the year travelling for research and speaking and this does impact on his ability to get enough sleep.   A strategy is firmly in place though, as Marshall takes a power nap on a daily basis.  If sleep has been short the night before, he resolutely schedules an empty time in the day precisely for this purpose. His naps vary in length between one to two hours and Marshall has developed a specialist skill that enables him to power nap anytime, anywhere in the world and on any surface. 

Sleep deprivation can be torture and has been used as a weapon for centuries. When tired, your body acts as though you have a blood alcohol level of 0.05, although being tired isn’t quite as much fun as having a glass of wine!

The jury is still out on the exact amount of sleep required but most people need 6-8 hours per night to be effective and perform at their peak.  The variables in determining how much sleep we need include: age, state of health, the weather, physical activity, employment challenges and your emotional state. Each of us innately knows how much sleep suits our own body. It doesn’t mean that we listen!

The Rebels

There are publicly stated exceptions to the rule.  This includes Margaret Thatcher (four hours), Winston Churchill (five), Bill Clinton (five to six), Leonardo da Vinci (five), Napoleon Bonaparte (three to four), Madonna (four), Silvio Berlusconi (two), P Diddy (less than four), Martha Stewart (two to four) and Donald Trump (three to four).

These politicians and celebrities have bragged about how little sleep they need – with the implication being that they are tougher, more productive and more suitable for leadership because of it. But are they really based on some of the questionable behaviours?

Sleep is directly related to stress and resilience. If you don’t get enough sleep, you get stressed and being stressed lowers your resilience. Sleep deprivation also negatively impacts your ability to utilise food and blood glucose. Alarmingly, it also accelerates the ageing process.

No one is entirely sure why we sleep. We do know that it helps with rest and rejuvenation – of both mind and body. Growth hormones peak during sleep as do many enzyme reactions. Experts agree that we need it and that it is a learned behavioural pattern. 

Sleep Phases

Sleep is an active process involving two primary phases. Active sleep is called REM (Rapid Eye Movement) and quiet sleep is known as NREM (Non Rapid Eye Movement). 

The quiet sleep phase (NREM) accounts for 75-80% of the night and has four stages in each cycle throughout the night.

  1. This phase lasts 5-10 minutes. Body activity starts to slow down – muscles relax, temperature drops, breathing is regular, your mind can wander and you are easily awakened.
  2. There is bodily movement; you are soundly asleep but easily awakened by noise. We spend 50% of the night in this stage.
  3. Your body is almost totally relaxed and not easily awakened.
  4. The deepest level – muscles completely relaxed, little body movement, and you awaken very slowly from this fourth stage. 

The active part of our sleep (REM) is where dreams occur. Nervous and mental activities increase with body temperature and heart rate is also increasing. The characteristic darting of the eyes occurs during this phase of sleep. This occurs predominantly in the last third of the night.

How do you get good sleep?

  • Stick to a regular sleep schedule
  • Exercise regularly – but not 4 hours before bed
  • No napping after 3pm
  • Get up and do something if you are having trouble getting to sleep…rather than staying in bed and being restless
  • Make sure your bedroom is sleep conducive (the right temperature, dark and comfortable)
  • A warm bath or shower before bed can be helpful to attain restful sleep
  • Turn around the LED clock – watching the brightly lit numbers is not going to help get you to sleep
  • Try relaxation or meditation techniques – e.g. breathing deeply and progressive muscle relaxation.
  • Minimise alcohol, caffeine and tobacco before bed if they affect your ability to sleep well
  • Turn off the TV, computer or other devices at least 1 hour before bed
  • Try drinking a warm milk before bed, as it is conducive to restful sleep due to its tryptophan (protein) content

In the glaring light of a tired day, it is often tempting to give in to what is commonly known as the ‘nanna nap’. Many peak performers take a daily nap to keep their brain functioning at peak levels and like Barry Marshall, actually factor this into their day. 

In some European countries it is considered usual practice to down the tools each day after the midday meal for a power nap. Given that our productivity takes a nosedive when we are weary, a planned nap could be a possible performance enhancing strategy. Research has found that a nap lasting around 26 minutes will increase your performance. A nap lasting 45 minutes will increase cognitive performance for six hours. 

Are you a power napper?

  1. It’s the reason i look so young, though dyeing my hair is also a factor.
    I am in no doubt about its immediate impact on cognitive function and nap most days if I can manage it.

  2. That was most informative Julie. I shall print this out and shove in my husband’s face every time he pokes fun at my 20 – 45 min doze which occurs after lunch and between 1.30 to 2.30pm, most days.
    He doesn’t have one. Different body chemistry I suppose.
