Dogs don't see life through rose-coloured glasses, nor in black and white

For a few months now, I’ve been treating six-year-old Samuel, who has the beginnings of myopia.

Key Points: 
  • For a few months now, I’ve been treating six-year-old Samuel, who has the beginnings of myopia.
  • He’s very quick for his age and often asks me questions about tests I give him, and about what I see inside his eyes.
  • However, as an optometrist, I can offer some insights that might help answer Samuel’s question.

Cones and rods

    • The retina, the sensitive part that lines the back of the eye, has two types of photon receptors: cones and rods.
    • The cones, in the centre of the retina (fovea), perceive bright light and are responsible for colour perception.
    • There are three types of cones.
    • The brain combines the signals emitted by each of these cones to form the colour it perceives.

And what about animals?

    • For example, birds have a fourth opsin that allows them to see ultraviolet (UV) light.
    • Humans cannot perceive this light because our crystalline (internal) lens filters UV rays.
    • UV rays influence birds’ behavioural decisions, including foraging and their choice of a mate.
    • This is an advantage when it comes to spotting prey, as they can distinguish their heat even at night.

Back to Scotch

    • The vision of dogs — such as our friend Scotch — is quite different.
    • As a result, dogs have a wider field of vision (250 to 280 degrees), but less simultaneous vision.
    • This is equivalent to the vision of a very myopic person not wearing glasses.
    • And as an added bonus, they have an extra layer of the retina, called the tapetum lucidum — or carpet.
    • So it’s possible, depending on the colour of the ball, that Scotch will not see it, and as a result, will gaze up at Samuel with a lost look.

Overly flexible connective tissue causes problems in joints and throughout the body − and is often missed by doctors

Connective tissue is found throughout the human body, within and between structures as varied as muscles, nerves and internal organs.

Key Points: 
  • Connective tissue is found throughout the human body, within and between structures as varied as muscles, nerves and internal organs.
  • Many people, especially young women, have very flexible connective tissue.
  • Hypermobile connective tissue can also cause serious health problems throughout the body, including the gut, nerves, skin, urinary tract and even immune system.

Wide range of symptoms

    • While some forms have genetic markers, more than 90% of hypermobility conditions – including hypermobile Ehlers-Danlos syndrome and hypermobility spectrum disorder – do not.
    • Symptoms and severity can differ greatly from person to person and vary over time.
    • Symptoms can include widespread pain and frequent injury, irritable bowel syndrome, indigestion, hernias, frequent bruising and poor skin healing, trouble breathing, migraines and headaches, dizziness, fatigue, insomnia, anxiety and trouble concentrating.
    • Hypermobility experts now believe Ehlers-Danlos syndrome is not as rare as previously thought – and many people are misdiagnosed or undiagnosed.

Difficulties with diagnosis

    • Lack of a diagnosis can be frightening and discouraging for people with hypermobility spectrum disorder.
    • Patients are often told nothing is wrong with them and they are just complaining too much or have low pain tolerance.
    • A delayed diagnosis leads to worse function, increased pain and disability.

How physical therapy can help hypermobility

    • Although research is limited, existing research suggests that physical therapy can improve sensory awareness and motor control – and help patients identify, activate and strengthen stabilizing muscles.
    • Occupational therapy can also benefit hypermobile patients through environmental modifications, activity pacing and assistive and mobility devices like splints, braces and wheelchairs.
    • Once it has been identified, though, many strategies can help decrease pain and injuries – and improve function and quality of life.

Our vagus nerves help us rest, digest and restore. Can you really reset them to feel better?

Retrieved on: 
Thursday, August 24, 2023

In fact, we have two vagus nerves – a left and a right – and their optimal functioning is essential for good physical and mental health.

Key Points: 
  • In fact, we have two vagus nerves – a left and a right – and their optimal functioning is essential for good physical and mental health.
  • Many social media posts describe ways to reset the vagus nerves to reduce stress and increase calm.
  • But the vagus nerves also play a part in why socialising, sex and sports are good for our health and wellbeing.

Our rest-and-digest-and-restore system

    • The vagus nerves are part of the parasympathetic nervous system, which does the opposite: rest, digest and restore.
    • The sympathetic nervous system increases heart and breathing rates, slows down digestion and lowers the immune response.
    • The parasympathetic nervous system via the vagus nerves is the counterbalance to our stress response.

The wandering nerve

    • Vagus means wandering in Latin and is where the words vagrant, vagabond and vague come from.
    • These are the tenth cranial nerves, the longest of the 12 pairs of cranial nerves that connect the brainstem and the body.
    • However, about 80% of vagus nerve fibres carry information from organs back to our brain.

Can you measure the health of vagus nerves?

    • Instead, heart-rate variability is used as a surrogate measure of vagus nerve activity.
    • This is the slight beat-to-beat differences in heart rate that occur naturally, related to breathing.
    • Many wearable devices measure heart rate and heart-rate variability and can be a useful way to monitor vagal tone.

So is there any science to back the vagal nerve hacks online?

    • Cold-water immersion on the face or neck stimulates the vagus nerves via a reflex of the skin’s nerves.
    • Singing and humming can increase our vagal tone because the vagus nerve innervates our larynx (voicebox).
    • There are also claims simple eye movements can reset the vagus nerve.
    • Carotid sinus massage can also be used clinically to increase vagus nerve activation and lower a high heart rate.

Social connection and feeling safe


    Polyvagal theory suggests positive social communication and feeling safe increases vagus nerve activity. This promotes healthy growth and restoration activities in our body and increases positive emotions. The vagus nerves have a role in social communication because they are linked with our facial expressions and voice. Smiling and being smiled at can stimulate our vagus nerves.

Sport, sex and slowing down

    • Slowing down with others, such as lying down next to a friend on a picnic blanket and looking at the clouds, also stimulates the vagus nerves.
    • Whether it’s through mindfulness, paced breathing, sports, sex or simply smiling, increased vagal tone is important for good health and wellbeing.

Zimbabwe election: Can Nelson Chamisa win? He appeals to young voters but the odds are stacked against him

Retrieved on: 
Tuesday, August 22, 2023

A lawyer and a pastor, Chamisa is the most formidable candidate against the ruling Zanu-PF led by President Emmerson Mnangagwa.

Key Points: 
  • A lawyer and a pastor, Chamisa is the most formidable candidate against the ruling Zanu-PF led by President Emmerson Mnangagwa.
  • The incumbent took over after the coup that ousted the country’s founding president Robert Mugabe in 2017.
  • Chamisa is over three decades younger than his (81-year-old) opponent, and the youngest person running for president in this election.
  • His youthfulness has been a major issue in this election, as it was in the last.

Youth appeal

    • The World Bank puts the country’s battered economy at just under US$ 21 billion.
    • Chamisa’s appeal to the youth vote has been received along partisan lines.
    • For his support base of mostly young urbanites, Chamisa’s youth is his trump card.
    • But will this be enough to help him win his first election as the founding leader of CCC?

Voter apathy, funding and harassment

    • In addition to voter apathy, Chamisa must contend with other hurdles within the opposition movement and the usual obstacles of running for office in electoral authoritarian state.
    • Chamisa founded the CCC following his forced exit from the Movement for Democratic Change (MDC) in 2021.
    • The married father of three had been mentored by the opposition movement’s founder, the late Morgan Tsvangirai.
    • But Tsvangirai’s death in 2018 ended Chamisa’s career in the party as divisions grew between him and the old guard.
    • Job Sikhala, a senior member of the opposition, has been in jail for over a year on unclear charges.

One man show

    • On the social platform X, where he has more than a million followers, he regularly only shares Bible verses or ambiguous messages.
    • This is a lost opportunity for a candidate counting on the youth vote.
    • Many who hoped for change after Mugabe’s ouster are dismayed by the continuing economic challenges and increasing militarisation of the Zimbabwean politics.
