Most of us think social connection is a squishy topic—subjective and hard to define. And while there's much truth to this, there is no doubting the profound scientific data highlighting just how critical social connection is for all aspects of our health. It’s in our bones. We are wired to connect. Here with Dr Julie Radlauer, we discuss the social influences of mental health - namely Social Connection • Social Support • Social Capital • Social Media • Social Justice. Knowing these social influences isn't hard, but navigating and implementing them isn't always easy, and so Julie provides us science-based insights and actionable steps to help us support ourselves and others. If you struggle to ask for help, give help, find support, or connect with others during difficult times, listen to Julie. Her warmth and experience offer universal comfort and practical guidance.Dr Julie is a leading expert in the social influences of mental health and uses her experience to create impact within communities, systems, organisations, and individuals. As a doctor of public health and a licensed mental health counsellor, Julie’s work aims to answer why so many people struggling don’t access services and more importantly, how these people want to have their health needs met.Find Julie:LinkedInInstagramJulie's Book - Connect: 100 Ways to Create Happiness in Your LifeWebsiteTED talkMentioned in this podcast:Adam Grant - Give and TakeLean on me - Bill Withers You’re Invited - Jon LevyCaste: The Origins of our Discontents - Isabel WilkersonBelieve in People - Charles KochWant to watch this on video?

This episode explores the 3-P model of insomnia (Predisposition, Precipitation, and Perpetuation), the effects of sleep deprivation and disturbance on cognitive function, and the risks faced by shift workers and healthcare professionals from chronic sleep loss. The conversation also details the intricate relationship between our natural circadian rhythms, guided by light exposure, that are disrupted by many modern practices, and the potential for better aligning our biological clocks with nature through innovative tools and routines.Ben and Prerna also discuss sleep chronotypes - night owls and morning larks - busting myths around later sleepers being lazier and whether society may benefit from observing these patterns. Without prescription, Prerna shares how consistency in sleep can lead to better health outcomes and how technology can both hinder and enhance our sleep health.Dr Prerna Varma, PhD, is a Psychology Research Fellow in the School of Psychological Sciences at the Turner Institute for Brain and Mental Health in Australia. Prerna is deeply committed to examining as well as addressing sleep and mental health in underserved populations, including caregivers, people living with dementia, culturally diverse and other minoritised communities. She engages in and advocates for increasing public health awareness with the intent to improve sleep outcomes in our communities.Find Prerna:XGoogle ScholarStudies mentioned or related to this episode:Sleep regularity and mortality: https://doi.org/10.1093/sleep/zsad253 ; https://www.nature.com/articles/s41598-018-32402-5 ; https://www.medrxiv.org/content/10.1101/2023.09.08.23295231v1.full.pdfInsomnia and stress during COVID: https://doi.org/10.1080/15402002.2022.2074996Initial Testing of SleepSync app with shift workers: https://journals.sagepub.com/doi/pdf/10.1177/20552076231165972Sleep and relationship conflicts: https://journals.sagepub.com/doi/abs/10.1177/1948550613488952 ; https://doi.org/10.1097%2FPSY.0b013e3181ecd08a ;https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3056503/Want to watch this on video?
