Loud Noise and Our Health

If we live in an urban environment we are surrounded by noise – sometimes loud, sometimes more background – but it is always there.  The sounds could be traffic, railways, airplanes, construction, industrial sounds and noise from pubs, shops and cafes.  We are also assailed inside the home and our gardens from increasing noise levels from the technology and household appliances – for example years ago there were no electric leaf blowers, hedge cutters or even lawn mowers.

Remember the hearing never sleeps, so excess noise is affecting us even in the bedroom when we are asleep.

So does all this background noise have an effect on our physical or mental health?

Well the answer to the above question seems to be yes, noise is making us ill and distressed.  Noise has an effect on the body as it detected by the ears and processed by the amygdala centre of the brain – this is the area that deals with emotions.  The brain might interpret loud sounds as threatening (our evolution has led us to see these sounds as potentially life threatening) – stimulating the “flight or fight” response OR certain sounds are soothing and stimulate the “rest and digest” response.

The flight or fight response in turn triggers the release of cortisol and adrenaline.  If the level of these hormones are raised chronically the physiology of the body is upregulated eg heart rate and blood pressure increase and inflammation occurs.

Clinical studies have shown prolonged raised noise levels can increase the risk of cardiovascular disease, diabetes, dementia, mental illness/anxiety and even auto immune disorders like cancer.  Research would tend to indicate prolonged noise levels over 50 Db has a negative effect on health (an average office is about 60 Db and being by the side of a busy road is about 80 Db).

Sounds That Heal

The converse of damaging sound is healing sounds.  Typical examples would include –

  1. Nature sounds
  2. Gentle weather or water sounds
  3. Low volume classical music
  4. Mantra repeated audibly and quietly
  5. Gong Baths/Sound Therapy

One of the most healing sounds is the Yogic practice of Bhramari.  If you wish to practice just follow the guidance below –

  1. Sit up straight in any Yoga posture in a quiet, well-ventilated corner with your eyes closed. Relax the face.
  2. Keep your eyes closed for some time. Observe the sensations in the body and the quietness.
  3. Take a slightly deeper breath than normal then exhale making a humming sound (like a bumble bee).
  4. Optionally if you wish you intensify the practice by closing the ears to external sounds.  This is done  by placing the thumbs in the outer ear canal OR pressing the ear cartilage.
  5. Repeat the humming sound on every exhalation
  6. Sense the vibration throughout the body
  7. Practice for up to 10 minutes or until tired
  8. Lie down in relaxation pose/Shavasana

Pratyahara – The Hidden Techniques of Yoga

Well to be honest these ancient Yoga techniques that allow up to quickly regain control of an unruly mind are neither deliberately hidden or mystical.  Very few teachers in the West know or practice them and consequently they seem esoteric.

The practices in question are termed Pratyahara and are the 5th Limb of Patanjali’s Ashtanga Yoga system.  These practices are eminently accessible physical techniques to facilitate sense withdrawal. Control of the senses (“Indriyas” in Sanskrit) allows a direct experience of the Self with the mind out of the way.

In Hatha Yoga pratyahara allows for the transition from concentration (Dharana) to true meditation (Dhyana).

So what are these practices???  Well there are numerous practices that have physical techniques (often combined with the use of mudra/hand gestures).  Many of the more accessible practices of pratyahara are mentioned in the ancient Hatha texts such as the Hathayogapradipika, Gheranda Samhita and Shiva Samhita.

ALL ARE BEST LEARNED DIRECTLY FROM A TEACHER.

However one or two are simple enough to be learned alone, here is one.

Khechari Mudra

  • Taking a comfortable seated position allow the spine to extend up and the limbs to drop down
  • Take up to 5 minutes watching the breath and if necessary release the need to “correct” or “make better” the breath – WATCH WITHOUT COMMENT.
  • Close the eyes if not already done so, relax the face and tongue
  • TAKE YOUR ATTENTION TO THE VERY TIP OF THE TONGUE AND NOTICE THE SENSATIONS – keep the root of the tongue as relaxed as possible.
  • After 5 to 10 minutes let the eyes gently open and enter the external World

 

Strength Training and the Older Adult

“Exercise might be the most important longevity ‘drug’ that we have for extending the quality and perhaps quantity of our years of life,” Dr Peter Attia Physician and Author

Whilst cardiovascular exercise is undoubtedly important, the latest research points to the development and maintenance of lean muscle (together with good metabolic health) as the key to a enjoyable, disease free later life.

After the age of 30 years, we lose 5% of our muscle mass per decade.  Also the composition of the muscles we have change as we age – with the fast twitch (strength) fibres being replaced by the slow twitch (endurance) fibres.

Population studies of the use of resistance/strength based exercise, shows that is can significantly reduce the incidence of the diseases called the “4 horsemen of the apocalypse” – heart/circulatory disease, cancer, diabetes and dementia.

Muscles together with the hormone insulin manage blood glucose (muscles soak up glucose), increase your BMR (basal metabolic rate – the rate you burn calories at rest) and reduces body fat.  Strength training also maintains and even increases bone density.

Well what type of strength training should you do to benefit from the massive health benefits shown in studies?

  1.  Perform strength training to include all major muscles groups – legs, hips, back, abdomen, chest and shoulders
  2. Exercise 2 to 3 times per week
  3. All weighted exercise is useful – bands, weights and even bodyweight
  4. 6 to 12 repetitions of each exercise and 2 or 3 set

The End of Ageing?

As cells age and become damaged or mutate, the body will normally dispose of the damaged cells via a process of programmed cell death called “apoptosis”.

However for some reason as yet not fully understood, this process of removing the damaged cells does not always happen and the body effectively “zombifies” a number of these cells that are not killed into a state called “senescence”, but where the cells can long longer replicate/divide.

Senescent cells exist in a state of suspended animation BUT they do keep on secreting a number of very inflammatory proteins which can lead to ageing AND illness.  Senescent cells are known to cause – diabetes, osteoarthritis, heart disease, cancer, Alzheimers and Parkinson’s Disease.

Research is ongoing within the world of pharmaceuticals/nutraceuticals and preventative medicine into a whole range of drugs that called SENOLYTICS that actively seek out senescent cells and destroy them.  Research so far would seem to indicate these drugs may indeed slow down (or possibly reverse ageing).

So apart from taking part in medical research and clinical trials are there any foods or supplements that may have a similar effect – well yes there would appear to be?

The following are commonly found in commercial supplement products and may well have the ability to reboot the programmed cell death process to remove the “zombie” cells.

Common Ingredients Targeting Senescent Cells

  • Fisetin
  • Quercetin
  • Apigenin
  • Curcumin
  • NAC (N-Acetyl-Cysteine)
  • Theaflavins

The Age of Anxiety

Anxiety – that feeling of dread or foreboding accompanied by physical bodily sensations (eg sweating, rapid heart rate, nausea etc) – has been with the human race since we lived in caves.  Indeed anxiety is an evolutionary trait that helps keep us safe in a hostile world by changing our behaviour eg being careful near rivers and lakes.  Later anxiety probably developed as a tool to keep social groups together (to stray outside social norms generates anxiety).  So in it’s original state anxiety was adaptive and functional.

However in the modern world commentators speak of an epidemic of anxiety disorders, partly the result of the complexity of societies and technologies.  Unrelieved anxiety states however damage our physical health by depressing the immune system and on a psychological level make life miserable.

Some of the simplest ways to reduce our anxiety are via exercise and diet.

  1. Strength training (low to moderate resistance)
  2. Aerobic training (low to moderate intensity)
  3. Mindfulness and Yoga moderate our interioception (the perception of bodily sensations) and reduce habitual mental reactions to changes in bodily sensations.
  4. Good quality sleep, 7 to 8 hours, is essential for all over health both physical and mental
  5. Being in nature for 1 hour a day has been shown to reduce anxiety
  6. Eat a healthy diet and maybe try a probiotic and have lots of fibre in your diet.  Good gut health is associated with reduced anxiety levels as a healthy microbiome helps produce feel good hormones like serotonin, dopamine and a chemical called butyrate

A Yogic Practice for IBS and Acid Reflux

Within the body of Yoga are many therapeutic practices to help the practitioner overcome illness and mental distress, through the practice of asana (exercises), pranayama (breathing) and meditation/relaxation.  This post will look at a simple but highly effective technique to relieve two common digestive issues.

It is estimated that about 12% (8 million) of the population in Great Britain have Irritable Bowel Syndrome and 20% (13.5 million) have acid reflux.  Both conditions can be debilitating and greatly interfere with our lifestyles.  Untreated both conditions can lead to more serious problems.

In Yoga it is believed that gastric problems are often the result of insufficient or excess Agni (the energy of the gastric fire) centred at the navel.  Surya Bhedhana is a highly effective technique to manage the symptoms of IBS and Reflux.

A Simple Pranayama Practice to Balance Agni – Surya Bhedhana

  1. Take a comfortable seated posture – sitting on a chair is acceptable.  The most important thing is to keep the spine erect.  Close the eyes.  DO NOT PRACTICE THIS TECHNIQUE DRIVING, SWIMMING OR IN ANY VULNERABLE SITUATION.
  2. Begin by observing the breath and try to slightly lengthen the exhalation.
  3. This practice consists of breathing through the right nostril and out through the left nostril.
  4. Take the index finger and place it at the eyebrow centre – you will be using the middle finger and thumb to open and close the nostrils
  5. Close the left nostril and breathe in gently through the right nostril – then close the right nostril, release the left nostril and exhale.  Immediately close the left nostril and repeat the cycle of inhale via the right nostril and exhale via the left.  All breaths are normal length and intensity.
  6. Continue to inhale through the right nostril and out through the left for 15 to 20 minutes.
  7. Lie down and relax for 10 minutes
  8. Surya Bhedhana can be practiced for up to 2 or 3 times per day.
  9. stronger version of this practice is to breathe in and out solely through the right nostril.

NB – People with uncontrolled high blood pressure or serious cardiac issues should seek the personal guidance of a professional teacher before proceeding.

Simple Yoga Techniques to Help Anxiety and Depression

There are many techniques in Yoga to help when anxious and depression – here are some of the simplest techniques for you to try.

Anxiety

  1.  Exhale for longer than you inhale
  2.  Focus on relaxing the tongue when you feel stressed

Depression

  1. Keep the outer corners of the eyes open
  2. Inhale for longer than you exhale

For serious and long lasting anxiety or depressive states please consult your doctor or mental health professional.  Yoga practitioners should seek the help of an experienced Yoga teacher.

A Daily Yogic Practice for Calm

We are all aware of days when we little energy, feel sluggish and just want to slouch around all day.  On other days we feel driven, have lots of energy, feel a bit edgy and are mentally active.  Occasionally we have those days when we seem to be perfectly balanced mentally and physically and the World seems a very benign comfortable place.

Well in Yoga there is a concept that material things (including ourselves) are affected by the Gunas.  The Gunas are states of energy and affect all matter universally.  There are 3 states (or attributes) of energy or prana, these being –

  • Tamas – ignorance, inertia, laziness
  • Rajas – passion, activity, movement
  • Sattwa – goodness, calmness, harmony

These attributes are in constant flux in our bodies, but in Yoga we are aiming for a balance of Tamas and Rajas which is said to naturally bring about the meditative peaceful state of Sattwa.

When we are more Rajasic the energy or prana in our bodies is said to move the FRONT of the body and when we are more Tamasic the prana moves to the BACK of the body.  In Sattwic states the prana resides in the centre of our beings.

Arohan/Awarohan Meditation

This is a daily practice to bring energy or prana back into balance.

  1. Sitting in a comfortable seated position, take a few moments to sense the body, emotions and mind.  Have the eyes closed.
  2. On the inhalation visualise the breath start to ascend from the base of the pelvic floor travel up the FRONT of the body until it reaches the throat – at this point the breath moves to the BACK of the upper neck and continues to travel up the back of the skull until it reaches the top of the head.  Here the inhalation finishes.
  3. On exhalation visualise the breath moving down the FRONT of the forehead, face and chin – when it reaches the throat the breath moves to the BACK of the lower neck and travels down the spinal column to the tailbone and pelvic floor.  At this point the exhalation finishes.
  4. REPEAT steps 2 and 3 for 5 to 10 minutes
  5. At the end of the practice sit quietly and observe the energy state of the body

NOTE – It may help to visualise this breath movement as a “figure of 8” with the crossover point at the throat/neck

Food Allergies and Intolerances

The Difference Between Allergies and Intolerances

The symptoms of both conditions may be very similar and can even confuse the experts, as both cause unpleasant symptoms and inflammation!

Generally food allergies are triggered by a protein and cause the body’s immune system to over react – with serious systemic symptoms (maybe life threatening).

Food intolerances generally only affect the digestive tract and are less severe than allergies.  They are caused by –

  1. absence of an enzyme
  2. psychological stress
  3. IBS
  4. Sensitivity to food additives
  5. Inflammation of gut when exposed to gluten

Common Foods Causing Allergies

  • Milk (and dairy produce) – mainly seen in children
  • Peanuts
  • Tree Nuts
  • Soy
  • Eggs
  • Fish
  • Shellfish

Common Foods Causing Intolerances

  • Dairy – usually caused by a sugar called lactose
  • Gluten – a protein found in many grains, especially wheat, barley. Gluten intolerance may present as Coeliac Disease or the less severe Non Coeliac Gluten Intolerance.
  • Caffeine
  • Alcohol

Dealing with Allergies and Intolerances

Allergies –

  • Total avoidance of allergen
  • Desensitisation via oral immunotherapy
  • Anti histamines (mild to moderate reactions)
  • Adrenaline injections (severe reactions)

Intolerances –

  • Remove or reduce consumption of foods causing symptoms – an exclusion diet may be required to identify the culprits
  • Improve gut health generally via dietary changes and improving gut flora
  • Treat chronic gut infections eg H Pylori or candida
  • Add supplements to diet – especially Glutamine, N-acetyl glucosamine (NAG), Quercetin, Deglycyrrhizinated Licorice (DGL) and pre/probiotics.

Could I Have Leaky Gut Syndrome?

Up until recently the concept of leaky gut syndrome was dismissed by most in mainstream medicine.

The intestinal lining is made up of enterocytes and interspersed with immune cells.  These enterocytes form “tight junctions” and only allow certain items to pass in and out of the gut, such as simple sugars, fatty acids and amino acids.  However, when this barrier gets worn down and develops more and more microscopic holes, it allows other compounds to “leak” through, causing your health to suffer.

It is now thought that the bacteria in your gut (your microbiome or gut flora) tell the immune cells in the lining of the intestine what can be let through the gut wall.

If too many unpleasant molecules “leak” through the gut wall, the body’s inflammatory response is raised and a state of chronic inflammation occurs.

Many researchers advise to avoid “industrial” ultra processed foods that cause damage to the gut wall in the first place, increase our vegetable/fibre intake, use more plant oils and generally have a high quality diet.  Again pre and probiotic supplements may help.

The Importance of Strength Training

Whilst fitness disciples (and the media) often focus on cardiovascular training (eg cycling, running etc.), numerous studies have shown the importance of developing and maintaining strength for quality of life, longevity and avoiding chronic disease.

Some researchers even suggest that strength training is similar to saving into a pension, as when we get older the lean muscle mass we have built will protect us from chronic illness and frailty that often accompanies aging.

The development of muscular strength and endurance has been linked to reduced risk of CV disease, dementia, diabetes/metabolic syndrome and even cancer (the four great threats as we age).

By building muscle mass and strength we improve metabolism and reduce inflammation in the body.  Strength training is also a very effective way of managing weight.

There is increasing evidence that we should focus on the following elements in our strength workouts –

  • Grip Strength

Any exercises that work the upper limb up to and including the shoulder and upper back are useful, eg bicep curls, push ups

  • Balancing both Concentric and Eccentric movements in our workouts

Concentric exercise – movements where the muscle shortens as it contracts (lifting a weight).  Eccentric exercise – movements where the muscle lengthens as it contracts (putting a weight down).

  • Pulling Exercises

Exercises could include rowing, pull ups, deadlift and clean

  • Hip Hinging Exercises

These are often whole body exercises and include deadlifts, squats and lunges
