Most of us often find ourselves waking up in the morning just before our alarms go off. Have you ever wondered the reason behind it? Well, we have some intriguing news here! Scientists have confirmed that this particular action has an actual science-proven reason behind it. Let’s unravel this scientific mystery!
The Acting Nerves
With an alarm or not, our body can sense time even in a state of deep sleep. But, how exactly is this possible? Well, as per science, the human body is controlled by the suprachiasmatic nucleus. This is basically a ball of nerves sitting in the middle of the brain. These clusters of nerves play a vital role in controlling body temperature, blood pressure, and most importantly, the human sense of time. This nucleus also decides when you’re going to feel sleepy or wide awake. So, next time you feel unnecessarily sleepy, you know the culprit behind it!
The Sleep-Wake Cycle
We all have our unique body clocks responding to our routines. This body clock becomes more efficient if you head to bed and wake up at the same time every day. An important protein named PER regulates this sleep-wake cycle. The level of this protein changes throughout the day. When at a low level, PER leads to low blood pressure, making you groggier and sending the signal to your brain that it’s time for bed. As per scientists, if you can stick to a regular consistent sleep schedule, your body will learn to naturally adapt to the cycle and will increase the level of PER in your body just before your morning alarm is due to go off. This automatic increase usually starts to happen around an hour before the set alarm time, as the stress hormones begin to release. This chemical-neural combo work in your body is the cause of you finding yourself waking up just a few minutes before your alarm goes off.
