# 30: Insomnia - Part 5
Some of the first neurological-related discoveries about insomnia were made by placing healthy sleepers or patients with insomnia inside brain scanners, and measuring changes in the activity in different parts of the brain as they tried to fall asleep. In the good sleepers, three main regions of the brain started to shut down at sleep: 1) emotion-related regions, 2) basic alertness-generating regions, and 3) the sensory awareness gate of the brain. There were also changes in the functional co...

#29: Insomnia - Part 4
Today’s episode focuses on changes within the bodies of people suffering from insomnia. Almost all forms of chronic insomnia come with a significant psychological component, namely emotional distress and anxiety. This starts a Rolodex of anxiety spinning once you turn off the lights. This leads to rumination and catastrophizing, which will thwart any hopes of a good night’s sleep. Since psychological stress is one of the principal triggers of chronic primary insomnia, researchers went in sear...

#28: Insomnia - Part 3
Today’s episode takes two questions as its subject: first, why does someone develop insomnia, and second, what adds gasoline to the sleep-disorder fire of insomnia and only makes it rage more powerfully? These are two very complex questions, but through lots of great science and wonderful scientists, we now have a conceptual model explaining how you may find yourself falling into the pit of insomnia. This is called the “3-Ps” model, and it consists of a three-step knock-on cascade of factors ...

#27: Insomnia - Part 2
There is no quick test that can determine insomnia. Instead, the diagnosis of clinical insomnia disorder is based on a set of clinical assessment and interviews. These center on three core features: 1) difficulties falling asleep, 2) difficulty staying asleep, or 3) waking up and not feeling refreshed by your sleep. Furthermore, to receive the diagnosis, you often have to be experiencing these things at least three nights per week; and having these issues for three straight months. One ...

#26: Insomnia - Part 1
Today’s episode is the first in a 7-part series on insomnia. Matt starts with a calming reality—insomnia isn’t a single bad night or a string of bad nights of sleep. In the US, epidemiological studies have suggested that insomnia disorder is as prevalent as the obesity epidemic: around 10-15% of the population suffer from clinical-grade insomnia, making it the most common sleep disorder. Indeed, one out of every two people will experience insomnia during their lifetime. It is therefore very l...

#25: Optimising Your Sleep
Today’s episode focuses on optimising your sleep. It’s designed for people who don’t have clinical insomnia but would like to fine-tune their sleep. Matt goes over five conventional tips, and five unconventional tips that may be new to you. The first tip is regularity—going to bed and waking up at the same time every day. Your brain has its own master 24-hour clock, the suprachiasmatic nucleus, which expects regularity. Second is temperature—your brain and body need to drop their ...

#24: Sleep is Bloody Remarkable #2
Matt is back this week with his recurring series, ‘Sleep is Bloody Remarkable’. Today’s episode is all about why we are unique when it comes to sleep. When we compare our sleep to that of all other primates, humans stand out in two ways. First, we spend far less time asleep, and second, and in bloody remarkable 😂 contrast, humans get more than double the amount of REM sleep. Unlike many other primates, we humans are exclusively ground (or bed!) sleepers. In contrast, primates usually sl...

#23: Dreams – Part 6
In this episode, Matt goes deeper into his exploration of lucid dreaming. He tells us all about studies demonstrating that lucid dreamers can wake from dream sleep on command, demonstrating control over intention in their dreams, and even bring themselves to orgasm in dream sleep! Matt tells us about two leading methods for developing the skill of lucid dreaming. The first is Mnemonic Induction of Lucid Dreams, which involves the creation of a conscious, deliberate intention to remember...
