Why can’t I sleep?
Understanding your sleep cycle
Sleep is an essential part of our Circadian Rhythm: our 24 hour internal clock that cycles between day and night (read: awake and asleep).
Sleep is the time that our bodies rest, recover and restore for a new day. And a good night’s sleep is brought on by natural cycles of brain activity. Once we close our eyes and seep into dreamland, we should be going through three stages of non-REM (NREM) when our bodies are progressing into deep sleep. This is followed by the rapid eye movement (REM) cycle, also known to be linked with dreaming. Normally during a healthy sleep rhythm, we go back and forth between both these cycles.
If our sleep is interrupted or we’re not able to repeatedly cycle between NREM and REM, we’re not sleeping deep enough. As a result, you feel exhausted, frustrated and drowsy. Read on below to find out more about why you can’t sleep and what you can do about it.
