In this guest post, nutritional medicine practitioner Shannon Barge from @livingwithrosie highlights how the latest scientific research about the human microbiome is changing the way we look at the connections between health, sleep and weight.

New Australian research is leading the world in one of the first human studies looking at the way sleep effects microbes and health.

In her research at CQUniversity Dr Amy Reynolds is looking at existing evidence in mice, showing the connections between sleep deprivation and microbes, and her research is now collecting data in a novel pilot study looking at the changes in human gut microbes resulting from sleep deprivation.

Although it is early days for Dr Reynold’s timely research, preliminary results suggest that there is a two-way relationship between healthy microbes and healthy sleep. What this means is that healthy gut microbes could address the negative effect of insufficient sleep, and this could be the basis for a revolutionary approach to treating obesity.

While we wait for the results of this scientific study why not do your own experiment. Make sure to get your zzz’s AND your greens to see if good sleep + good food = healthy gut, and healthy gut + good sleep = feeling great!

Getting to the guts of the matter, CQUniversity

    The Goodnight Co.

    Shea Morrison has worked in health & wellness for a while now. After a career in Media, Radio & Marketing in Brisbane, Shea became a Mum and her focus changed as she realised the importance of meaningful rest and connection. In 2014, Shea joined forces with friend, Mum and now business partner, Danielle Knight to create The Goodnight Co., a meaningful platform to help people fall back in love with sleep and prioritise meaningful rest. At the time, Shea & Danielle were sleep deprived Mums after just having had their youngest children. Launching with Silk Pillowcases & Silk Sleep Masks, the pair then spent the next five years researching and surveying hundreds of people about their sleep problems, gradually developing many more lines of products to help our customers build sleep rituals to solve these problems. Fast forward five years, millions of research papers and thousands of podcasts, Shea's passion continues to lie in sharing how better sleep can help everyone improve their day-to-day lives.
    With sleep problems still on the rise, Shea & Danielle were constantly being asked for more information on how to help people re-discover quality sleep. As a result, The Goodnight Co.'s first Sleep Retreats and Sleep Workshops launched in 2019. The Retreat & Workshops allow personalised help for those struggling with disrupted sleep patterns and provide a mixture of education and relaxation, science and deep sleep, meditation and mindfulness.
    For our Retreats, Shea & Danielle found the perfect location at Springfield Farm in the Southern Highlands of Bowral; a beautiful location with lots of space to connect with nature, fresh air, nourishing food and a space to support our guests, who could walk away feeling equiped with the tools to re-build their sleep rituals. For our business focused Workshops, Shea & Danielle have been able to connect with workplace professionals and provide tailored industry specific advice on how sleep can be impacting employees and what management and staff can do to improve this area of their health, and productivity.
    Along with The Goodnight Co., Shea is also a Mum to Max & Molly, wife, Director of boutique advertising agency, Collaborative Media, marriage celebrant, entrepreneur, and avid podcast subscriber.
