Do You Struggle With Broken Sleep? Why Your Diet May Be To Blame.

Ditching the processed foods not only help us to feel better (and shake off a few extra kilos!), but it also helps us to sleep better.

This is because most processed foods are:

  • Low in dietary fibre required to support optimal gut health. Poor gut health impacts the production of certain hormones and inhibitory neurotransmitters such as gamma-aminobutyric acid (GABA) and glycine, which help to calm the nervous system and encourage better sleep. Lack of GABA also contributes to anxiety in a lot of people, which can make it difficult to fall asleep and stay asleep.
  • High in refined sugars which feed pathogenic bacteria leading to an imbalance of gut microbes, otherwise known as dysbiosis. For example, when there is an overgrowth of a yeast infection such as Candida, it causes inflammation in the gut. This in turn triggers production of cortisol – a stress hormone that also acts as an anti-inflammatory. When cortisol levels are elevated, it can contribute to insomnia because it dampens down production of the sleep-regulating hormone, melatonin.
  • Deficient in nutrients that play a role in sleep such as vitamins B1, B3, B5, B6, folate, magnesium, zinc, iron and calcium – all of which help to facilitate the many biochemical processes required to produce melatonin. For example, magnesium, calcium and vitamin B5 act as co-factors in the conversion of serotonin to melatonin.

So if you’re struggling with continual bouts of broken sleep (on top of working shift work), it might be time to take a good look at your diet. Because gut disturbances and nutrient deficiencies as a result of consuming foods that are highly refined and processed may be further contributing to your sleep disturbance – in addition to the shift work itself.

Is Your Brain Getting A Signal That It’s Safe To Sleep?


Going to bed stressed will make it near in possible for you to sleep, because the body is in a state of ‘fight or flight’.

This fight or flight mode sends a signal to your brain that it’s actually not safe for you to sleep. Quite simply, you need to stay awake to fight off any predators – real or imagined!

When this happens the body produces cortisol, a hormone that works in opposition to melatonin – a hormone that helps to regulate sleep.

In other words, high cortisol = low melatonin = a delay to sleep onset.

Not ideal if you’re a shift worker – especially on those tight turnaround shifts when sleep is at a premium!

It’s why implementing strategies to help you to relax prior to getting into bed, is absolutely key in helping you to fall asleep.

Putting Our Shift Working Jobs Into Perspective.

Having grown up in rural NSW and watched my house burn to the ground when I was just 7-years old, the images that we’re seeing right now of widespread bushfires around Australia is nothing short of heartbreaking.

The sheer devastation of loss including wildlife, livestock, property, vegetation and even human life, is gut-wrenching to see.

It’s why I feel it’s fitting to give a special shout out to all the firefighters who are on the front line, risking their own lives to help others 24/7.

Here’s just a snippet as to why:

✔️ Many of these firefighters are experiencing sleep deprivation on a whole new level.
✔️ Their “shifts” are longer than anyone should ever have to work.
✔️ They are having minimal meal breaks – if any.
✔️ Many are volunteers who have also taken leave without pay 💰 from their “real” jobs.
✔️ Despite being physically and emotionally exhausted, they keep going because they don’t want to let their communities down.
✔️ They are working in an extremely dangerous and hazardous environment 🔥.
✔️ They are subjected to a level of emotional distress that no one ever wants to experience – seeing countless burned wildlife and livestock, (and in some cases, the loss of human life).
✔️ Many are also working in the community in which they live. So when a house 🏡, or heaven forbid, a life is lost, it affects them right to the core.

So please join me in sending out an enormous gratitude of thanks for all of the incredible work that they are doing.

And the next time you’re experiencing a crappy shift at work, please keep in mind what the fire fighters are currently having to endure.

It definitely puts things into perspective and why they are truly deserving of the title of “HERO” – as I’m sure you would agree.

HSW 95 – Exercise, Mental Health and PTSD with Beck Lawther.

Today we’re talking about the benefits of exercise when it comes to managing our mental health – in particular around the topic of PTSD or Post Traumatic Stress Disorder with Beck Lawther, a Police Officer with the Victorian Police Service based in Melbourne.

Beck is also the co-founder of Triple Zero Fit, a personal training company which runs fitness sessions specifically for first responders and emergency services personnel who are struggling with PTSD, depression, anxiety and other mental health conditions.

Things we chatted about:

– What led Beck to set up PT4PTSD?
– Why taking a 9-5 job for a couple of years can be a great strategy to reset our physical and mental health
– Why simply getting to the gym can feel like an insurmountable task, especially for those suffering from PTSD
– How physical exercise stimulates hormone production that improves our mental health
– How you can become a volunteer personal trainer, or utilise some of the services offered by Triple Zero Fit

Reflecting on 2019 – 3 Things

Something to ponder as another year draws to a close, and we get ready to embark on a new one.

1. Do more of what’s working
2. Stop doing what isn’t working
3. Try new things to see what does work

What new things and changes are you going to make in 2020?
