From sleepwalking to sleep paralysis: the strange world of sleep disorders

Sleep disorders impact your ability to function during the day and get the rest you need at night

We all know sleep is important for our health. Everything from our heart health and weight management to our stress levels and mood can fluctuate depending on how well or poorly we sleep.

But sometimes there are factors impacting our sleep which are seemingly out of our control. These can include travel, social commitments or shift patterns. Or, they can be sleep disorders.

According to Mental Health UK, one in five people aren’t getting enough sleep, and sleep disorders like insomnia are largely to blame.

Even for sleep experts, there is a lot about sleep disorders that remains a mystery. Let’s take a closer look at the mysterious world of sleep disorders, exploring where they come from and how you can take steps to lessen their impact.

The spectrum of sleep disorders

Sleep disorders come in many forms, with a wide variety of conditions affecting the UK population. Insomnia is perhaps the most common, with the NHS estimating that one-third of people in the UK will experience episodes of insomnia at some point in their life.

Sleep apnoea is another prevalent condition, affecting around 1.5 million people in the UK, yet it’s believed that up to 85% of cases go undiagnosed, according to the British Lung Foundation.

More mysterious and less understood disorders such as sleepwalking and sleep paralysis are also an issue. Sleepwalking, particularly prevalent in children but also affecting adults, is estimated to occur in 2-4% of adults, according to research published in the Lancet.

Meanwhile sleep paralysis, a condition where individuals are temporarily unable to move or speak when falling asleep or waking up, affects around 8% of people, though episodes are often sporadic and not a chronic issue for most.

Sleepwalking

Sleepwalking, or somnambulism, is a phenomenon that intrigues many due to its almost eerie nature. It involves carrying out complex activities while in a state of partial arousal from deep sleep, leading to walking around, rearranging furniture, or even eating without any consciousness of doing so.

Genetic factors play a significant role, with studies suggesting that children are more likely to sleepwalk if their parents have a history of the condition.

Sleep Paralysis

Sleep paralysis sits at the other end of the spectrum, providing a stark contrast to the active nature of sleepwalking. It’s characterised by a temporary inability to move or speak while falling asleep or upon waking.

This can be a terrifying experience, often accompanied by hallucinations that can add to the fear. The exact causes are still being studied, but stress, irregular sleep patterns, and certain mental health disorders are known to be contributing factors.

Addressing sleep disorders

The impact of sleep disorders can be mitigated with the right approach. For insomnia, cognitive behavioural therapy (CBT) has been shown to be effective, offering a non-pharmacological treatment option.

Lifestyle changes, such as maintaining a regular sleep schedule and improving sleep hygiene, can also make a significant difference.

For conditions like sleep apnoea, advancements in treatment such as continuous positive airway pressure (CPAP) machines have provided relief for many sufferers. Meanwhile, understanding and managing stress levels can help reduce the occurrence of sleep paralysis episodes.

Sleep health: knowledge is power

Sleep disorders, from the common to the curious, affect a significant portion of the UK population. While treatments and understanding are constantly evolving, the importance of sleep health cannot be understated.

By acknowledging the impact of these conditions and seeking appropriate care, individuals can improve their quality of life and unlock the benefits of a good night’s sleep.
