Sleep Series: The Chemistry of Sleep

sleep series: chemistry of sleepDifficult 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.

Sleep Series: A Primer On Circadian Rhythm

sleep series

  • Circa – Circular – meaning the one going round and round – repeating itself 
  • “Di”an – Pertaining to Day – or Daily 
  • Rhythm – A regular & repeated pattern of movements (ups & downs) occurring naturally 

Circadian Rhythm (CR) is driven by consumption of light – (light again!) – however, research has proven that light is not necessary and it was observed that the rhythm works more or less correctly even if someone is locked in a very dark place for a long time. But it is also proven that light can drive/influence the rhythm.

Trivia: CR is not exactly 24 hours – it is approximately 24 hours + some 15 minutes! 

The Third Eye/Body clock – known technically as “Suprachiasmatic Nuclei” (why not a simple name?)  – of just 10,000 neurons ( brain has 100 billion) situated in the hypothalamus area of brain, exactly above the place where the optic nerves from the left and right eye do the “X over” to the other side of the brain, is the main controller of the Circadian Rhythm. It is impacted by the “light” signals coming from the eyes. 

Be very clear , the Third eye controls the “sleep-wake” cycle and it is sensitive to “light”!

Not all people have SAME CR!! They fall into either of the 3 types: 

  1. The Early Birds (25 %) 
  2. The Night Owls (25%) 
  3. The Commoners (50%)

There is approximately 1-2 hours of difference in the rhythm between the Early Birds and the Night Owls and the Commoners fall in between. To check your type, google it – web has several free tests. One of them is: https://www.realsimple.com/work-life/life-strategies/time-management/early-bird-night-owl

One’s energy levels, alertness, body temperature, heart rate all have clear correlation to the CR. It is proven that core body temperature falls by up to 2 degree Celsius and heart rate by up to 20 beats per minute. Modern day work environment requires one to have an average to above average energy level and alertness throughout the day. But it is a natural fact that it is NOT. So, we resort to coffee or tea (impact of caffeine in a separate note later). 

If we can closely observe and keep our key meetings in alignment with the CR, we may actually get more productive. In my personal experience I have observed peak productivity between 11-1 in pre-lunch and 4-6 in post lunch sessions. HR processes in companies could use such simple tests to identify rhythm types and create groups of people that complement each other to boost productivity. As I have often seen in boardrooms, there’s always one person presenting with lots of energy and some are following and some are behind! It could simply be the difference in their CR type.

Jet lag is primarily a result due to change in CR. Time clock of the geography and your CR are not aligned, hence the lag. It is said that the lag adjusts @ 1 hour per day.

Circadian Rhythm & Sleep – How To Make It Work For You

  • Observe your CR and understand your CR type, hours of peak productivity – they remain the same throughout your life. Use the natural surge in alertness to your advantage.
  • One tip to get sleep is to start on time and send clear signals to the CR system in the morning by standing in clear sunlight for at least 10 minutes (you might get Vitamin D in the bargain) – When CR registers that signal, it will promptly align the clock to trigger sleep in the night – I tried this as many days as possible
  • World over, people keep an alarm to wake up – Reverse the process – If only you can keep an alarm to start sleep at same time of the night, then you WOULD NOT need an alarm to wake up – that too grumpily – Stick to SAME time (or in a range of 30 minutes) to go to bed, even if you do not get sleep in the beginning.
  • One should reduce exposure to light post 7:30PM – send clear signals that it is night time – Candlelight dinners are a brilliant way to signal Melatonin secretion.

Sleep Series: In Praise Of Darkness!

sleep series

In the beginning there was only darkness and then, light came out of darkness! Light and darkness are not two different and opposing things. Society has made a villain out of darkness. Darkness is used as a synonym of all things sinister. We are trained from childhood to look at darkness with fear.

In Hindu religion, darkness is deified – we have “Maha Kaal” and “Maha Kaali” – in religion this could either mean “darkness” or “time” – there is close relationship between them, but that is for another day. 

There is darkness everywhere – interstellar, intergalactic is just darkness.

Modern living has opted for lights of high luminescence. The poor old incandescent light of 60 watt (tungsten filament bulb) has a luminosity of 400-800 lumens whereas the modern day LED lamps can produce the same lumens at just 5 Watts. Where we had one incandescent light, now we have at least 4 LED! Which means we are consuming 5 times more light! 

Light has to be light ( Pun intended)

Since we fear darkness, we have created a social necessity (business necessity?) for bright light, whereas the number 1 villain for good sleep is LIGHT! Many of us know of the bad impact of blue light emitted from phones, laptops and tablets. Evenings are intended to be a journey to acclimatize to emerging darkness and night time is intended to be pitch-dark by nature.

So, for a good night’s sleep, the gradual reducing of lighting and luminosity is a must. Which means after 7:30pm, you should: 

  • Slowly switch off lights and send a signal of reducing light to the eyes
  • Make the bedroom pitch-dark for sleeping
  • Immediately activate “night mode” in Laptops and Phones

This could easily be the first step towards good sleep! Remember that you are meant to sleep in darkness. The sleep hormone Melatonin (more about this later) is highly impacted by luminosity. Darkness is key to sleep. Light is an inhibitor of sleep. Embrace the darkness, start falling in love with it! Darkness is the source of all light, time and space and is a good first step to a good sleep.

Sleep Your Way to More Muscles

sleep your way to more muscleDid you know you can build muscles even while sleeping? The three aspects of the muscle building pyramid are nutrition, training and rest. Most of us pay close attention to the first two factors but frequently ignore the third and suffer the consequences. Sleep isn’t a luxury for the human body, it’s a genuine necessity. Extended periods of sleep deprivation can lead to amnesia, delusions and hallucinations. Shorter stretches cause forgetfulness, bad moods and irritability.

How Does Sleep Lead To More Muscles? 

If you’re trying to gain strength, sleep becomes even more important because it’s synonymous with recovery. If your body doesn’t get to fully recuperate from a hard workout, there’s no way it will be ready for the next one. Heavy training destroys tissues. In order for the tissue to be repaired, your body needs the proper nutrients and deep sleep. One of the key events that occur during sleep is that the body releases growth hormones which are critical for repairing tissues, maintaining tonus in the muscles and keeping the fat in the cells. Since the body releases growth hormones only during deep sleep, the question is how do you get deep sleep?

Getting enough rest is critical to your overall health. Lack of sleep, even for a single night, can have a huge effect on your immune system. Research has shown that there’s a 20-30% drop in the immune system cells that fight cancer and viruses after just one night of sleeplessness. If sleeplessness continues over several days, the percentage of decreased immune system cells climbs drastically. The good news is that you can bring the number of cells back to normal with a solid night’s sleep.

So How Much Sleep Is Enough?

That depends on individual to individual and it depends on many variables. Ideally, one should aim to get at least 7-8 hours of sound sleep. Sleep is the most critical variable affecting our workouts. How well we have slept the previous night will determine how good a workout you do the next morning.

Work-related stress is one of the many reasons that most suffer from sleep deprivation. One of the best things you can do is slip in to a nap prior to your workout. You don’t want to drop off into the deeper stages of sleep before training because it will make you groggy. 20-30 minutes is plenty before a workout.

How Can You Induce Sleep Quickly? 

Deep sleep at night is very important and here are some of the things we can do to get sleep fast:

  • Read to relax
  • Take a shower or soak in the tub
  • Listen to soothing music
  • Try Chamomile tea
  • Warm turmeric milk will induce melatonin, which is a sleep hormone
  • A light snack can be useful in promoting a more relaxed state, but it’s smart to select foods that contain the amino acid tryptophan, which converts to serotonin in the brain, helping you to feel drowsy. Milk, yogurt, cheese, turkey and fish contain tryptophan.

What to Avoid Before Sleeping 

Now here are some things you should not do if you want to have a good night’s sleep:

  • Don’t overindulge in alcohol
  • Avoid eating large quantities of food. Eating a large meal before bedtime isn’t conducive to sleep as the food will trigger various systems, including the heart, to work harder. Also, the digestive tract may become upset and disrupt sleep even more.
  • Avoid stimulants such as caffeine and nicotine. This includes tea, coffee and soft drinks as well.
  • Avoid any form of strenuous exercise or participating in a competitive sport as it will work against you. Vigorous physical activity stimulates the body, and it takes some time to calm you down.
  • Don’t take your work to bed. If you make your bedroom an extension of your office, you’re sure to carry business problems with you at night. Your bedroom should be a cool, dark, sleep chamber.

You may have to experiment a little to find out what works for you. But if you’re having trouble getting a good night’s rest on a regular basis, make some changes in your lifestyle, quickly. The “magical one-third of your life” is a critical variable in your quest to gain strength, so be mindful of that.
