Understanding bio-alarm clock

Sometimes when we are woken up we feel refreshed and sometimes we feel as if we did not have any sleep at all. 

Human sleep is a cycle which consists of waking stage, Non-REM Sleep and REM (Rapid Eye Movement) Sleep. In the waking stage, your body will prepare you to sleep. Your body will start to slow down, your muscles start to relax and your eye movements will slow down. After the waking stage, you will come to Non-REM Sleep which comprises of 4 stages and lasts from 90 – 120 minutes. In stage 1, the sleep is called drowsiness. The eyes are closed once you are in this stage. But if you are aroused from it, you might feel as if you have not slept. Stage 2 is the light sleep period. In this stage, the polysomnographic readings will show intermittent peaks and valleys, or positive and negative waves. These waves indicate spontaneous periods of muscle tone mixed with periods of muscle relaxation.

Understanding Heart Rate Variability

Heart Rate Variability, or HRV, is a new way to track your health. 

Heart rate variability is literally the variance in time between the beats of your heart. So, if your heart rate is 60 beats per minute, it’s not actually beating once every second. Within that minute there maybe 0.9 seconds between two beats, for example, and 1.15 seconds between two others. The greater this variability is, the more “ready” your body is to execute at a high level.

HRV is simply a measure of the variation in time between each heartbeat. This variation is controlled by a primitive part of the nervous system called the autonomic nervous system (ANS). It works regardless of our desire and regulates, among other things, our heart rate, blood pressure, breathing, and digestion. The ANS is subdivided into two large components, the sympathetic and the parasympathetic nervous system, also known as the fight-or-flight mechanism and the relaxation response.

Better sleep, better life.
