Sleep Series: Sound NOT OK Please! Everything You Need To Know About Sleep Apnea

Good sleep is ironically referred to as Sound Sleep. While “sound sleep” is Ok, sleep with “Sound NOT OK please!” Snoring is the “Lead Indicator” for sleep apnea. 30% of Males and 15% of females snore. Most of the male snorers beyond age 40 have a high chance of Sleep Apnea.

During sleep, the body parts relax and for few of us, the muscles around the air passage – throat and tongue – collapses (relaxes) and obstructs the airway. This:

Stops flow of air to lungs
Breathing stops
Oxygen level in the blood goes down – less than 90%, Co2 rises
Brain detects the low level and URGENTLY REACTS!

The brain sends signals to wake up, but to the collapsed parts only (normally the person still continues to sleep – hence he just does not know the issue) and then the cycle continues.

During Apnea, there are complex harmful hormonal reactions in the body: https://www.hopkinsmedicine.org/news/media/releases/more_evidence_untreated_sleep_apnea_shown_to_raise_metabolic_and_cardiovascular_stress

Sleep Apnea kills slowly! Sleep Apnea unleashes Diabetes and Hypertension and lethargy of course, among a myriad of other diseases. I first noticed that I may have apnea since I felt very sleepy in office meetings. That they were boring is another reason, but I felt sleepy in ALL meetings! I was tired and lethargic.

How I Tackled Sleep Apnea

My “sound sleep” was like a Lion’s Roar! I heard my recordings – first it was my wife who talked about it, then even my sons, who sleep in the adjacent room. That’s the time, coincidentally, GOQii folks were discussing sleep apnea, CPAP machines, etc. There was a free polysomnography (sleep test) going on offer and I grabbed one. The results confirmed a mild version of apnea and I promptly purchased a Philips APAP (more advanced than CPAP) machine.

I struggled to get used to sleeping with a face mask but as I got used, the benefits were telling! I invariably woke up fresher, singing a song and ready to Carpe Diem. I was more attentive in meetings (asking even tougher questions) and then the health benefits began pouring in – my hypertension plummeted, and the quantum of medicines dropped – my overall quality of life improved

The reason why I shared my personal story bit more elaborately:
I had a sleep problem that resulted in

Low productivity
Stress and strain as I worked hard to compensate for the low productivity
Irritability due to poor sleep – bad 360 degree feedback
I was taking more coffee to stay awake – resulting in further loss of sleep – caught in a vicious cycle (read caffeine and sleep here)
Suffered from an avoidable hypertension issue for at least 15 years and took all kinds of beta blockers resulting in even deadlier side effects
I HAD NO CLUE and sadly NOT EVEN MY DOCTORS
NO doctor EVER asked me ANY questions about my snoring or sleep quality – NOT a comment on the Doctors, but on the system, treat for the “symptoms” that we narrate.

Therefore, YOU ARE ACCOUNTABLE for your HEALTH!

Talk to your body, understand the signals (language of body) it is sending – even better, measure it regularly
In Mumbai, I found just two sleep doctors on Google – I consulted with one of them. (Just 2 for Maximum City? No wonder Mumbai is a city that does not sleep)
I read Matthew Walker’s book on Sleep, read many blogs and watched many Videos
Used CPAP Machine, understood its readings, correlated with GOQii Smart Vital readings and made corrections to lifestyle
Invested in upgrading my bedroom
Experimented with a few foods (next/last blog) and adapted what was suiting me
Then, finally decided to share it on LinkedIn, because that is my community

Summary

Sleep Apnea is MORE common than what gets detected and treated
Sleep Apnea is not just a health problem, it is the biggest killer of productivity – HR Folks, note this!
Low productivity results in even more hard work for knowledge workers
Responsible for ALL MAJOR lifestyle chronic illnesses like Diabetes and Hypertension
If you feel sleepy in the office before lunch, then watch out, you may have sleep apnea whether or not you snore ( feeling a bit sleepy during the second half is ok)
If you are over 40, then I strongly advise you to consult a sleep doctor and take a polysomnography test. Make it part of the Master Check Up
If you snore, then do not wait, get yourself tested for apnea

Modern CPAP and APAP machines are fantastic. They are as comfortable as they can get and they give you a comprehensive MIS on your sleep the next day. More importantly, they have high quality air filters, which filters pollutants and smaller dust particles – that’s an added benefit!

Sleep Series: Sleepy Notes

In the previous articles, we went into what influences sleep and factors that guide it. Today, let’s take a look at some sleepy notes to help you improve your sleep!

Sleepy Notes To Improve Sleep

Measure: Sleep is measured both quantitatively and qualitatively and both are important to score perfect sleep. For you to say that you slept well – scored 10 out of 10, myriad things have to happen during the 6-8 hours. You could use some kind of sleep measurement tools like the GOQii Smart Vital. You will get lots of data – as CXO folks say, “What gets measured gets managed!”
Bedroom: We saw earlier that bedroom should be DARK. Buy darkening curtains and blinds.
Cool & Clean: It is ideal to sleep with the aircon on every day so that the temperature is uniform. Considering the air pollution, it is critical to keep an air purifier for Indian conditions with high levels of pollutants. Western blog writers have recommended 20 Degree Celsius – For Indian bodies, I reckon 24 is ideal, which is what I do.
Equipment: Sleep equipment includes the mattress, pillow, bedsheet and the comforter. Do your research – be as passionate as you are when buying a smartphone or car. You earned your sleep. Sleep comfortably! You spend one third of your life in it – this is NOT an expense – but an investment – Period. A good benchmark for investment is invest NOT LESS THAN the value of your CAR! You should also REPLACE them periodically.
- Mattress: You literally want to bounce back to life. A mattress should allow body heat dissipation , if possible make it cooler, provide for the spinal contours and curves and overall invite you to sleep. Most mattresses allow a 100 days sleep trial. Don’t forget to change your mattress every 7+ years or so – but do change it once a while. A mattress is definitely NOT for your lifetime. Also ensure that you clean the mattress once in six months at least. Many service providers do vacuum and dust mite cleaning. Very important. Do not let millions of dust mites sleep along with you on your mattress.
- Pillow: Choose a pillow that doesn’t cause any pain to your neck. Pillow varieties can be confusing – I use a Memory Foam pillow. Try a few and stick to what suits you. Once again, trial is allowed here as well and make sure you replace them once in 2-3 years.
- Bed Sheet: Choose one that allows heat dissipation to the mattress. Pure Cotton (bamboo is even better) and High Thread Count – Minimum 300 thread count is recommended for that 5 Star Hotel feel and conducting heat. Replace once in 2-3 years
- Comforter: Prevents heat dissipation and allows cooler air. Pure Cotton and high thread count. Replace them once in 2-3 years
Power Nap: An afternoon nap for 15-30 minutes is very refreshing and powerful. I am aware of many CXOs sleeping in the office with lights switched off, wearing noise cancel headphones and eye masks. I found it useful and do this occasionally. Just in case you foresee working late on any day, a nap will help you keep going at full power till late into night.
Alarm for Starting sleep: I strongly suggest that you keep an Alarm for STARTING sleep, most likely you WONT NEED an alarm to wake up. Starting sleep at the SAME TIME every day is extremely critical to have good sleep.
Sleep Positions: Sleep how you feel comfortable. Side position with bent knees (closer to Fetal Position) is what suits most people.

Sleep Series: The Relentless Rivalry of REM and NREM

When we sleep, we go through a few stages. Prominent among them are REM and NREM. It is observed that for some non-specific reason, there is significant movement of the eyeball in all directions rapidly during REM sleep BUT does NOT send any visual signals to the brain. Hence, the name Rapid Eye Movement ( REM) sleep and the opposite – Non REM sleep. Some also say that they are “deep sleep” vs “shallow sleep” which I am not a great fan of. I believe they are simply various stages of sleep.

Courtesy: sleepadvisor.org and Mathew Walker.

IF we draw a graph of brain neural activity, the graph will look something like this

As you can see, at the start it is the NREM which is occupying the real estate and the REM shows up intermittently. Approximately each of the cycles lasts for 90 minutes and then it changes. But in general, we can see the domination of NREM in the first half and REM in the second half.

Interesting Facts on REM and NREM

Dream your way to creativity: As homo sapiens came down from trees to sleep on flat grounds, they developed REM sleep as an evolutionary advancement. REM sleep is responsible for the evolution of creativity, memory and problem solving. It is during REM sleep, the neural network gets more intricately wired with new synapses being formed. In some sense, it is the REM sleep that contributed to the supremacy of humans over other animals.
Early morning school timing inhibits creativity: If schools, colleges or universities start pretty early in the morning, it is quite possible that the student has to wake up early and hence, foregoes some part of REM sleep. That is NOT good news for memory and creativity, which are most critical for studies.
Sleep algorithm is an enigma: NREM has been measured in 4 stages depending upon how deep it goes. The deeper it goes, the body gets better rest and the housekeeping activity of scavenging the brain of useless memory and storing of useful memory in the long term storage area happens – this is a totally involuntary activity based on an enigma algorithm. God/Nature is the first and best coder.
Forgetting is beautiful: The brain decides to delete (forget) what is irrelevant. You will definitely not remember what breakfast you had the same day last week. Forgetting is an essential function just as much as remembering is.
Striping emotion – REM heals: REM sleep is responsible for stripping emotion from past events over time. For example, you would remember the death of a close relative. But rarely you can recollect the emotions that were recorded when it happened. It is a blessing in a way. It is not the Time, but it is REM that heals!
7 hours or nothing: 5 cycles of 90 minutes – 450 minutes approx. 7 hours gives you a good full cycle. Anything less is like jumping 90% of the well! Short sleep leaves work undone and there is no use. You add to the pressure of work.
There can be no sleep “Deposit” and Sleep “Loans” ( this would appeal to the Finance community). You cannot oversleep to compensate for a past deficit nor you can accumulate a deficit to be cured by oversleep a bit later. It is 7.5 to 8 hours a day, every day! You would now have understood why from the chart above.
You cannot “Live your dream”: The motor activity other than breathing is all frozen during REM stage , all muscles (particularly limbs) are frozen – imagine you swishing your sword or trying to run away when chased by a cobra! It protects you from getting injured!
You are not meant to remember your dreams: You will only remember that you had vivid dreams or nightmares. Dreams have been the subject of so much research. Only one thing is clear – every dream is made of illogical and impossible combinations. If you behave during the day like the way you behaved in your dream, you will find yourself in a psychiatric ward. It is the façade or alibi as the brain is reorganizing the hard disk.
Dreams have no meaning: Do not over analyze, dreams have no hidden meaning. If you need to know something, why would it be revealed in your dream? It would rather appear in Times Square visible to all.
NREM is all about detox and growth: NREM sleep detoxifies the body, grows tissues, improves immunity, repairs injuries. Breathing slows down, body temperature goes down, blood pressure drops and the body gets a deep relaxation to get ready for the next day.
You need both: It is NOT that NREM is better and preferred than REM. Combined activity and result from both is critical for overall physical and mental health.

Sleep Series: The Chemistry of Sleep

Difficult to believe? Yes it is true. The perfect sleep is the result of a complex reaction from 2 main chemicals. Adenosine is a neurochemical which accumulates during “wake” and drains during “sleep”. Imagine a specially made hourglass, but one which builds up for approx. 16 hours of our wake cycle and drains within 8 hours of our sleep cycle. The receptors of Adenosine inform the brain that “stock levels are up” and it is time to relax and sleep. As sleep kicks in, stock levels of Adenosine goes down and receptors send a “wake up” signal to the brain.

Adenosine is the primary inducer of sleep-wake cycle. It reduces neural activity and sets you to start sleep. Interestingly, Caffeine blocks the Adenosine receptors and creates the opposite effect. There we go – as to why we feel a bit fresh and brisk after a cup of coffee – it is an illusion we create by confusing the brain! The body’s excretion system works hard to flush Caffeine. It takes 5-6 hours to flush out just 50% of this possessive chemical.

I’ve mentioned Adenosine over Melatonin as the primary sleep chemical because I wanted to impress upon the impact of Caffeine. We take Caffeine in many forms – Coffee, Cola, energy drinks, etc. Caffeine also impacts the Dopamine and Serotonin chemical reaction, thereby causing a significant disruption of the normal neural activity.

Do let Adenosine do its job naturally, you will sleep on time and naturally! Caffeine interferes with several hormonal/neurochemical reactions related to sleep. Do not consume Caffeine beyond lunchtime and in any case, beyond 4pm.

The Magical Darkness Hormone – Melatonin

Melatonin is the second chemical responsible for enabling “onset” of sleep. It detoxifies the body of free radicals and other toxins. It starts secretion as soon as darkness sets in and it peaks by midnight. The synthesis of melatonin occurs through a multistep complex chemical process:

It all starts with food – food contains an amino acid called tryptophan. Foods like Milk, oats, nuts contain more tryptophan.
Tryptophan is absorbed from the bloodstream to the pineal gland in the brain.
First, tryptophan is converted to another amino acid and then to a brain chemical called Serotonin. 2 Enzymes are involved here!
Serotonin’s conversion to melatonin involves two more enzymes.
All chemicals discussed here follow complex routines and they are part of a chain which is amazingly responsible for the onset of sleep. On top of it all, there is a closely coordinated play of the “Brain-Gut complex” to get this right!

How Can You Aid This Natural Process For Good Sleep?

DON’T intervene in the natural process! Supplements can’t get you anywhere near the good quality sleep offered by this natural process.

Beware of Caffeine! – Stop post lunch consumption
Consume foods high in tryptophan – consult your GOQii coach
Gut (Serotonin storage) has its role in sleep, so keep it clean and healthy
Get used to darkness after dinner to catalyze natural Melatonin

Adenosine has other functions such as certain cardiac functions as well. This article does not deal with them. An enzyme is a biological catalyst that speeds up the rate of a chemical reaction and an amino acid is an organic acid used to make proteins usually obtained from food. OTC Melatonin – a small dose is usually fine to get over jet lag.
