Whilst hallucinations and slurred speech aren’t things most of us stress about after a night without sleep, it is clear that not acquiring the correct amount of sleep can be bad for our health and wellbeing. In addition, the time you wake up can affect how you feel in the morning as well.
WHY YOU STILL FEEL TIRED EVEN AFTER A FULL NIGHT’S SLEEP
Do you ever get out of bed feeling tired, even after a full night of sleep? This can happen when your brain has been woken in the middle of a deep sleep, and has not had the time to gradually return to a mindful state. It’s a well-known problem, but we now have ways to solve it with sleep clocks that know when it is the ideal time to wake us, and when it isnt.
OUR SLEEP PATTERNS EXPLAINED
Our nightly pattern of sleep isnt just shifting from light to deep sleep and back. Instead we are thought to go through four different phases of sleep, including REM, light and deep. Additionally we go through these stages four times every night as our brains process our memories and revitalize for the following day.
Each cycle lasts about one hour and a half and are categorized by different types of brain activity and movement. This is how sleep clocks know when it is the ideal time to wake us, because during a light sleep we move around more as our bodies raise themselves from their state of rest.
HOW SLEEP CLOCKS KNOW WHEN TO WAKE US
Sleep clocks are a new wave of devices that monitor our sleep patterns and can measure when we are going through a light sleep phase. During a preset time window, the sleep clock will set off the alarm to help us awake at a time when we will feel most alert and refreshed.
While they all work in a similar way, there are a variety of sleep clocks to select from which can offer varying results. This includes mobile apps where the smartphone is put on the bed or on a pillow and then the smartphone analyses our sleep patterns through our movements. When you start moving around in the morning, the alarm will then activate to help you to awake at the best time.
