When we give ourselves ample opportunity to sleep and we don’t remember being awake overnight, it can be really frustrating to then wake up feeling as though we’ve not slept or at least that we’re not refreshed by that sleep. But why does that happen? This blog is all about the many reasons why we may not be getting restorative sleep.
Firstly it is important to state that no-one ever wakes up feeling instantly alert and bounces out of bed with bags of energy. We all have a degree of something called sleep inertia first thing when our alarm goes off. Sleep inertia is simply the remnants of sleep before we reach full consciousness. As it is impossible (as a healthy adult) to go from being fully alert to being asleep, so it is impossible to go from being asleep to full consciousness instantly. The length of time it takes us to move out of sleep inertia can vary between individuals and personally varies between days. Typically sleep inertia lasts for between 15 and 60 minutes. It is harder and takes longer to wake up if we were in a deep sleep when aroused but this usually only happens if you are awakened by something unplanned, such as a fire alarm going off. You can shorten the time it affects you by getting lots of light in your eyes or washing your face with cold water as soon as you wake up. Lots of people try to shortcut sleep inertia by drinking caffeinated drinks but quite often this is totally unnecessary and if they allowed themselves the time they would find that they do not need the caffeine at all.
If you are still struggling with feeling unrefreshed an hour after waking and you have not knowingly had interrupted sleep or too short an opportunity to sleep, then it may be that you are not getting enough of the type of sleep that your body and brain requires. When we sleep, we constantly move between different phases or stages of sleep. For more information regarding our sleep cycles, please see here. In order to feel well rested on awakening we need to have had enough deep sleep and REM sleep. It is in these two stages of sleep that we hit the reset button on most of our biological systems and give ourselves some well-needed therapy, without which we can feel physically and emotionally drained.
Unrefreshing or non-restorative sleep can have lots of different causes, some physical, some psychological and some environmental, but all of them in some way prevent us getting into or interrupt our deep sleep and/or REM. These micro-arousals mean that you are spending the night in only the light levels of sleep.
