    Do dreams have a social function? Covid-19 Special Report

    Do dreams have a social function? Covid-19 Special Report

    This week we explore 'pandemic dreaming' - a phenomenon where people around the world, experiencing lockdown during the coronavirus pandemic, have reported an uptick in incidences of dreaming and more vivid dreams.



    We talk to two academics who, for several years have been undertaking an art/science project, DreamsID in which individuals recall a dream, which is then transformed in real time to a work of art.



    We talk about some of the reasons behind 'Covid dreams', art, symbolism and metaphors, an overview of contemporary theories of dreams' functions, and explore new theories of how the act of sharing dreams may strengthen social bonds by increasing feelings of empathy.

    This episode's guests:





    Mark Blagrove is a Professor of Psychology at Swansea Univeristy. He studies the relationship between sleep and cognition, including effects of sleep loss, memory consolidation functions of sleep, causes and possible functions of dreaming, nightmares, and lucid dreams.

    Screens, tech and sleep - it's not all about the blue light

    Screens, tech and sleep - it's not all about the blue light

    In recent years we've been bombarded with advice warning of the dangers of sleep-stealing blue light emitted from smartphones, tablets and computer screens.



    But scientists and health experts are slowly coming to realise that the melatonin-blocking function of short-wavelength light is only part of the story regarding the reasons why technology keeps us awake at night.



    In this episode we talk to renowned sleep expert Dr Michael Grandner about the complex and nuanced ways that technology can contribute to a lack of sleep - discussing not just the role of blue light, but also the addictive nature of social media algorithms, how different types of digital media affect sleep, and offering some practical tips to help you manage your smartphone addiction.

    Dr. Michael Grandner is the Director of the Sleep and Health Research Program at the University of Arizona, Director of the Behavioral Sleep Medicine Clinic at the Banner-University Medical Center, and an Associate Professor in the Department of Psychiatry at the UA College of Medicine, with joint appointments in the Departments of Medicine, Psychology (UA College of Science), Nutritional Sciences (College of Agriculture and Life Sciences), and Clinical Translational Science.

    Sleep, diet, obesity and weight gain: Part 2

    The second instalment of a wide-ranging conversation with associate professor of neuroscience, Christian Benedict on the fascinating, complex and still as yet fully unravelled associations between sleep, obesity, diet and weight gain.

    This Episode's Guest





    Christian Benedict Ph.D. is an Associate Professor in neuroscience at Uppsala University where he heads up a team of scientists at the Benedict lab, which studies the effects of circadian disruption and sleep loss on health and performance, with a particular focus on the relationship between sleep loss and metabolism.

    Sleep, obesity, weight gain and diet - Part 1

    Sleep, obesity, weight gain and diet - Part 1

    Does a lack of sleep lead to a higher risk of obesity? Or does being overweight lead to more likelihood of sleep problems? Around the world,  scientists have been trying to unravel this chicken and egg problem for decades. What's clear so far is that to understand the associations between sleep loss, diet, obesity and weight gain, sleep scientists have to confront a dizzying array of knowledge domains including psychology, neuroscience, epidemiology, genetics, endocrinology and more.



    Today, in a two-part episode we speak to associate professor Christian Benedict, a  sleep research who has spent almost two decades in the field and now heads up his own team of researchers and doctors and Uppsala University. 



    We discuss the many associations that we currently know about sleep, diet and obesity, including how sleep loss impairs our cognitive ability to make good food choices, how sleep plays a role in our body's energy expenditure equation, the role of food in our circadian system, how 'hunger hormones' are impacted by sleep loss, which diets are more/less impactful on our sleep patterns and a whole bunch of other stuff.

    The truth about melatonin

    The truth about melatonin

    In recent years melatonin has exploded in popularity as a 'wonder drug' - a safe, natural supplement for helping with sleep problems. Whilst there's lots of scientific evidence to back up many of the claims, the fact that melatonin, at least in the United States is classed as a food supplement, rather than a prescription medication, has led to a lack of consistent public health messaging, and a great deal of confusion amongst the millions who take melatonin supplements on a regular basis.



    In this episode we try to cut through the marketing hype, dispel some myths, and find out what the real facts are about melatonin and its role in sleep, as we speak to Professor Helen Burgess, one of the leading melatonin researcher in the United States.



    As well as discussing the basic biology concerning the role of melatonin we talk about the practical ins and outs, dosages, timing, use cases, side effects and also some of the latest findings in scientific research about how melatonin may play an important role outside of sleep issues, having implications for health conditions such as inflammation, some cancers and diabetes.

Dogend Jenkins ,

Fantastic resource for insomniacs like me

Thanks for putting this together.

Informative and an eye opener to sleep

This podcast covers so many issues to do with sleep, it looks into the science behind disorders and connections of sleep to other conditions such as epilepsy.

It also addresses many issues that have caused us great pain on a personal level where the world seems to be divided on whether to let your child “cry it out” at night or nurture them and be there for them at a critical time of development in their lives. Thank you for bringing so many issues of sleep to the public and for the knowledgeable people you interview to bring awareness to us all.

A goldmine of sleep info

There's so much unresearched nonsense talked about what happens when we sleep, so it's refreshing to come across a resource like this. Sleep is a subject so utterly essential to who we are and how we are, we could all do with paying a bit more attention to it me thinks. But then of course quality attention needs to be rewared with quality information and I've been getting that here so thanks. Looking forward to many more Sleep Junkies podcasts. Good work peoples.
