Feeling Sleepy? Have a Nap. It's Good For you!

Here's a very valid case to have a power nap. Experts say an after-lunch snooze is good for you and your productivity.

If you’ve ever felt the need to rest your head on your work desk to secretly get a few minutes of post-lunch shut-eye while the boss wasn’t watching, it turns out you’re not lazy or disinterested. In fact, you are very normal.

According to Moira Junge, sleep psychologist and member of the Sleep Health Foundation, we were designed to require an afternoon kip to get through the day.

“We are all pre-programmed to need a little nap in the afternoon, explains Junge. “What happens with our body’s sleep mechanisms is that we have a post-lunch dip in our system and have a propensity to sleep.”

Junge explains the ‘post-lunch dip’ in our 24-hour circadian rhythm is like a sleepy switch that just flicks on in the afternoon. It’s independent of what we eat and of the amount we’ve slept the night before. This dip also gets repeated at night around 11pm and is the reason why some of us ‘crash out’ around that time.

“We are all pre-programmed to need a little nap in the afternoon. What happens with our body’s sleep mechanisms is that we have a post-lunch dip in our system and have a propensity to sleep.”

But, says Junge, what’s unique about this afternoon napping signal is that it’s temporary. It lasts 30 minutes to 1.5 hours before we go back to feeling alert again.

“If you don’t get an opportunity for sleep, say if you are at work, you can cycle through this dip quickly as your body’s systems will rise again, with or without a sleep if you can just manage to stay awake through it.”

Professor Leon Lack from the School of Psychology at Flinders University is pro-power napping and says if we can, we should. He reminds me that our need to nap in the afternoon is the reason why siestas are an accepted practice in many countries and explains that napping is a natural human habit dating back hundreds of years.

“We’ve become so fixed in our cultural habits of having a single nighttime sleep,” Prof Lack tells SBS. “This idea is a reasonably recent cultural adaptation from the industrial revolution and because of the advent of electric lights.

“Over 300 years ago, when most people were rural farmers, you probably had naps in the middle of the day and stayed up a little later at night but only so long as the fires burned in your house.”

So let’s say one day, our workplaces radically changed to become pro-napping zones. How long a kip should we have on our desk before the alarm rings? Junge says the trick is for the nap to be very short: 20 minutes is ideal, with time dedicated for you to fall asleep.

“If you sleep more than 20 minutes, you get into that deep slow wave of sleep where you can’t hear anything or wake up and don’t know where you are,” says Junge.

“That’s because the first 20 minutes of sleep are very light, stage one and two of sleep, and if you sleep for longer, you are more likely to have sleep inertia, where you wake up and feel worse or take a long time to ‘wake up’ and get going. Longer naps might also affect your sleepiness and ability to sleep at night. So short, sharp naps are recommended.”

Prof Lack goes even further to suggest that the average adult should be having 10 minute power naps in the afternoon, as needed, with a few minutes added to fall asleep.

He co-conducted research in 2006 comparing no naps with naps of five, 10, 20 and 30 minute durations. The 10-minute adult nap gave participants the biggest rise in alertness with the minimal amount of post-nap grogginess.

“With the 20 and 30 minutes sleeps, performance was impaired a little bit immediately after waking up for the first half hour or so,” says Prof Lack. “But the 10 minute naps produced significant benefits in cognitive performance.”

"Stop the struggle and have a quick kip so you can be more productive at work for the rest of the day.”

The moral of this dreamy story, Prof Lack suggests, is that if someone is really struggling with sleepiness in the afternoon, it’s likely they will continue on struggling for up to 90 minutes until they come out of ‘that dip’.

“So managers should find out what’s better for the worker. Is it better for them to be below par at work for 1.5 hours [during their afternoon dip] and potentially make mistakes? Or allow them 15 minutes – five minutes to relax and fall asleep and 10 minutes of napping – to increase the productivity for the remainder of that 1.5 hours?

“Napping could be considered beneficial if you are struggling with sleepiness in the day, commonly in afternoon and have a decline in alertness. Stop the struggle and have a quick kip so you can be more productive at work for the rest of the day.”

Both experts stress that this advice is general and that sleep needs vary according to individual needs and circumstances. They recommend that people with sleep disorders consult a GP and, if needed, see a sleep specialist.

A Dan­cer’s Brain De­vel­ops in a Unique Way

Music activates our deeper brain areas, but what happens in a dancer’s brain? Movement can trigger a flow state which makes way for an intuitive neural network.

As technology takes over more areas of our lives, interest in more natural ways of life has also increased massively. One example of this desire to reconnect with nature is the upsurge of yoga and meditation retreats.

Music and dance have been fundamental parts of the human experience for millennia. They have enabled interaction which has given rise to close communities and rich cultures. 

Neuroscience has studied music for decades. It has been found to activate the deeper brain areas in a unique way. Deep brain areas are primarily responsible for emotions, memory and social interaction.  They evolved in the human brain much earlier than the cognitive functions in the cortex. 

Deep brain areas are primarily responsible for emotions, memory and social interaction.

My doctoral dissertation developed methods for understanding the processes that dance generates in the cortex. 

I compared the brain functions of professional dancers and musicians to people with no experience of dance or music as they watched recordings of a dance piece. The brain activity of the dancers was different from that of musicians and the control group during sudden changes in the music, long-term listening of music and the audio-visual dance performance. 

These results support the earlier findings indicating that the auditory and motor cortex of dancers develops in a unique way. In my study, the dancers’ brains reacted more quickly to changes in the music than those of musicians or members of the control group. The change is apparent in the brain as a reflex, before the dancer is even aware of it at a conscious level.

I also found that dancers displayed stronger synchronisation at the low theta frequency. Theta synchronisation is linked to emotion and memory processes which are central to all interpersonal interaction and self-understanding.

In dance, the basic elements of humanity combine in a natural way.

Touch and cooperation are integral elements of dance – without them, there can be no dance. They are as important to dance as movement and music. 

However, the neuroscience of dance is still a young field. Consequently, the brain processes of touch and cooperation have not yet been studied through dance specifically. 

We do know that in dance, the basic elements of humanity combine in a natural way. It combines creative act, fine-tuned movement and collaboration, much like playing music. The movement involves the whole body, like in sports. There is touch, like in gentle interaction. 

Dancing is also associated with “flow”, a well-researched phenomenon in which the person becomes fully immersed in an activity. Flow experiences have been found to increase the general contentment and productivity of the person as well as the quality of the activity. It reduces the activation of the neural network which is responsible for logical deduction and detailed observation. 

This makes room for the creative neural network which also has an important role in generating a relaxed state of mind.

Practicing an instrument requires extreme precision. It has been found to shape motor processes in the brain in many ways. Meanwhile, studies conducted on dancers reveal how their brains have specialised to process dance motion. 

Certain areas of dancers’ brains have specialised precisely to observe dance movements. The brain structures of musicians and dancers have also been found to differ from the general population in the areas responsible for processing movement and sound.

Brain synchronisation enables seamless cooperation.

Studies on producing music and movement show how during cooperation, the brains of two people become attuned to the same frequency. This is apparent in how the low-frequency brain waves of the participants become synchronised. 

Brain synchronisation enables seamless cooperation, and is necessary for creating both harmonic music and movement. The ability to become attuned to another person’s brain frequency is essential for the function of any empathetic community.

Lately, researchers have gained fantastic results regarding the role of exercise as a mood enhancer. In addition to drug treatment and psychotherapy, exercise is currently even being recommended as a form of treatment for depression. Exercise releases hormones that create a sense of wellbeing, which in turn boosts positive emotional processes in the brain. It also lowers the activation of the amygdala, the brain’s fear and stress centre. 

Finding the right dance style can make dancers euphoric, and make them forget the drudgery of official exercise recommendations and step counters.

Dancers who pursue graceful movement must practice being aware of their bodies and (being aware) of wordless communication. These skills are particularly important today, when we spend so much time sitting and in virtual realities. Our way of life has taken us further from our own physical experiences and the understanding of the wordless emotional messages of others.

For example, contact improvisation makes the dancers to listen attentively to the body of their partner. Touch is known to reduce pain, fear and anxiety. 

Functional brain imaging has shown that these effects of touch are also apparent in the brain. In one study, a touch from a significant other reduced the intensity of the pain activation in the brain during an electric stimulus when compared with pain experienced alone.

Pain, stress and anxiety often go hand in hand with depression. Dance, music and related expressive forms of therapy could help lessen mental fluctuations even before the onset of full depression. Promising results have been gained from treating depression through music therapy. 

Dance therapy can help with many disorders of the mind and body, from anxiety to dementia and Parkinson’s disease.

Dance is a highly subjective experience. However, neuroscience can help us understand how people can use dance to feel more connected to each other in our technology-filled world.

What Does Arthritis Mean For Younger People?

Think arthritis only affects the elderly? Think again. By 2030, an estimated 580 million people worldwide, ages 18 and older, will have been diagnosed with the disease. Pretty eye-opening, right?

Conventional medicine tends to treat arthritis with strong, immune-suppressing medications that temporarily relieve the symptoms of the disease. Unfortunately, I've seen how these medications can also damage your gut and how they fail to truly address the root cause of the issue. This World Arthritis Day, it’s time to make a change. I’m here to tell you that there’s another way—a way that’s designed to address the underlying causes—in order to reduce inflammation without medication. Here’s how:

1. You can treat all kinds of arthritis with one approach.

There are more than a dozen different kinds of arthritis, and while there are certainly differences in conventional understanding and treatment for each one, they all have common root causes and triggers for inflammation and pain. For example, the two most common diagnoses are rheumatoid arthritis (RA) and osteoarthritis (OA). While RA is considered an inflammatory (autoimmune) disease and OA is typically thought of as the result of "wear and tear" and injury to the joint, both of these conditions are influenced by lifestyle choices such as diet and exercise. No matter what kind of arthritis you have, it’s important to know that it can be made worse by inflammation that starts elsewhere in the body, including the gut. Which brings me to my next point…

2. Heal the gut, and you heal the joints.

You may have heard some talk about gut health—and the gut-brain connection or the gut-pain connection—and you’ve probably heard the word "microbiome," or the friendly bacteria in your body. Fascinating studies have confirmed that the root cause of your arthritis is most likely lurking in your digestive system, so to heal your joints, you must first heal your gut. But where do you start? The best first step is to take a probiotic daily to help remove the harmful microbes that might be causing your symptoms, but some require a more intensive plan.

3. Treat your terrain with inflammation-fighting foods.

A fresh start for your microbiome means a new chance to influence your "terrain," or what I think of as the body’s deepest soil, where cells either thrive or wither. There’s a strong connection between your diet, your gut microbiome, and your pain level, so I recommend choosing foods that fight inflammation like organic plants and foods high in fiber and healthy fats, while avoiding refined sugars, dairy products, and red meats. Here are some of my guiding principles:

• Increase fiber, micronutrients, and phytonutrients, or, in less-scary terms, eat more vegetables and fruits, and choose organic whenever possible.
• Reduce refined sugar, high-fructose corn syrup, and refined grains.
• Improve the quality of fat by removing refined oils and hydrogenated fats.
• Improve the quality of the animal protein you eat by choosing 100 percent grass-fed and finished beef, free-range chicken, and sustainably farmed, low-mercury fish.
• Limit salt, food dyes, and preservatives (which happens naturally when you limit processed foods).

4. Carve out time for daily stress-reduction activities.

Traumatic events and ongoing stress are very real triggers for inflammatory diseases. In our go-go-go world, we’re always rushing; we can’t miss this deadline or that meeting, and we very rarely take the time to sit back, relax, and let our minds reset. Diet and stress are two root causes of a damaged gut, inflammation, and chronic disease, so it’s no surprise that in order to heal your arthritis naturally, you must take time to practice your favorite stress reduction activities daily. I recommend meditation, yoga, long walks through nature, and journaling to ease the mind.

5 Steps to Bounce Back From a Bad Day

A bad day starts when you spill coffee everywhere on your way to work. Then you space out about the important tasks you had to get done. The icing on the cake? Your boss cancels a presentation you spent all yesterday preparing for. Bottom line: Today sucked.

Even if you love your job, an occasional bad day is par for the course. It can be hard to shake grouchiness when you wake up on the wrong side of the bed, are annoyed by at work, or distracted by world events or relationship drama.

The secret to recovering from a bad day is learning how to move forward despite it. How you respond can mean the difference between a quick recovery and a full-blown funk.

Here are 5 steps to help get you back on track so you can come back stronger tomorrow:

The only constant is change.

That’s why we created the Making a Change course and guide. Whether you’re starting a new job, moving across the country, or changing a habit, Making a Change will prepare you to get Unstuck. 
Learn more here >

Step 1: Embrace your bad day

You’re human, and like the rest of us, you’re bound to make mistakes or have moments where you’re not performing at 100 percent. As much as your inner perfectionist may be freaking out, forgive yourself. Give yourself permission to feel bad (for a little while at least).

Release any anger, guilt, or self-blame so that you can move on. Take a breather and walk around the block. Scribble out your frustrations in a journal. Call your mom or best friend. There’s no shame in crying in the bathroom, either!  

Step 2: Change your mindset

Once you’ve moved through the sorrow, shift your mood by asking yourself, “How do I want to feel right now instead?” Calm? Joyful? Strong? Consciously generate positive emotion so that you can get back to work with a fresh perspective.

Watch for ways you may also be blowing things out of proportion (“I’m not good enough. I always screw up” or “Nothing ever goes according to plan”). Unhelpful thinking is common, but you can unhook from it by reframing your perspective. To do so, first identify those automatic negative thoughts, then tweak your self-talk to be more balanced and realistic.

Step 3: Recalibrate mentally and physically

As you may know, bad days affect both the body and mind. Stress shuts down many normal functions, which is why you may feel anxious or rushed and experience symptoms like tunnel vision or shallow breathing when things are going badly.

Try bringing blood, oxygen, and calm back into your system with a grounding practice, stretching, or a few jumping jacks.

Step 4: Treat yourself — the healthy way

Don’t confuse self-care with self-sabotage. Skip drinking the day away at happy hour. Steer clear of numbing out through food, TV, or another substance or bad tendency. Focus on what restores you and makes you genuinely feel good, even in the tiniest way. That may be giving a calling a friend, going to bed an hour earlier, or saying “no” to a networking event so you don’t overextend yourself.

Step 5: Leave it behind

Emotions are contagious (including negative ones) and when work sucks, unhappiness can follow us home. Draw a boundary with an evening routine to signal the shift and bring closure to a bad workday.

At home, speak up and let your family, roommates, or maybe your pets know you’re having a rough day. Request space to decompress if you do need it, but resist the urge to isolate. Connection with others, even virtually, is an important component of happiness. It helps us realize that bad days are universal and also serves as a much-needed source of support and advice.

No one is perfect. Life rarely works out exactly as planned. Instead of beating yourself up when a crummy day happens, expect them. And remember, you get to decide how you respond when bad days happen. Will you let it derail you? Or will you choose to see it as a tiny bump in the road on the way to achieving your goals?

Ironically, a bad day can be a hidden gift — it’s an opportunity to show to yourself exactly how resilient you are. You have the capacity to do hard things, so go show today who’s boss.
