Sleep is one of the most underrated parts of our well-being and self-care routines. We all know that feeling of trying to get through a workday when you’ve sleepless nights — you feel brain fog all day and can’t get enough coffee. But how can sleep affect our performance and overall health outside of work? We’ve got some answers from some sleep experts in the PepTalk network.
How to hack your sleep
We’ve all heard the standard advice of getting 7-9 hours of sleep, but that’s only half the story. NHS data lead Dr Raphael Oliya highlights how the sleep process works:
To start, you’ll go through four to six sleep cycles during sleep. Each cycle lasts 90 minutes on average and is composed of 4 stages. The split between each stage and duration of cycles is called your sleep architecture.
So, let’s look at each stage and their different functions for your mind and body. The first three stages (NREM sleep) progressively put your body into a deeper sleep. The final stage, REM sleep, is when the brain is most active, but the body is the most inactive.
- Stage 1 (N1): Dozing off, easy to wake up the sleeper and usually lasts 1-5 minutes
- Stage 2 (N2): Temperature, heart rate, and brain activity drop. There are short bursts of brain activity. This stage initially lasts 10-25 minutes but lengthens throughout sleep. You generally spend up to ½ of your sleeping time in this state.
- Stage 3 (N3): Deep sleep where the body relaxes even further. Crucial for physical recovery, immunity and key brain functions. At the beginning of sleep, this lasts for 20-40 minutes per cycle but reduces with every cycle as the sleeper will spend more time in REM as the night goes on.
- Stage 4 (REM): Brain activity increases, but the body slips into temporary paralysis of the muscles apart from those that help you breathe and perform eye movements. Often associated with dreaming and is essential for brain functions such as memory, creativity and insight. This type of sleep makes up for more of your cycle as the night goes on.
Laying out these key stages, you can see how just a few hours of insomnia or restlessness can prevent you from reaching the all-important N3 and REM stages. The body moves into REM sleep only when you’ve had at least one cycle so even a couple of hours can really make all the difference to your brain functioning the next day. Yep, that’s where the brain fog comes from.
Preventing a restless night
Kathryn Pinkham, a sleep coach and insomnia specialist, notes that good sleep is about rewiring your brain. Sleep is closely linked to stress (both physical and mental) and the types of thoughts we have about ourselves.
If you're struggling with sleep Kathryn recommends taking the time to notice negative thought patterns. Once you are aware of them, try to create counterarguments to them. This technique will allow you to process negativity throughout your day rather than lodging itself in your mind and becoming a barrier to your sleep.
Next, she recommends repositioning your beliefs about your sleep. For example, we all know that sinking feeling when we look at the clock and only have a few hours until our alarm. Come armed to this situation with statements such as ‘Whatever sleep I get, I know I’ll cope tomorrow’. This removes the personal stress and blame from the situation, giving you a sense of power and control over your sleep.
Self-kindness goes a long way when you’re struggling with sleep or experiencing sleep deprivation. Accept your situation and ask yourself what you need to get to sleep or get through the day.
