  1. Because when a person has a constant mode, even in a state of sleep, his brain keeps time. The biological clock works steadily and predictably, the brain manages to get enough sleep in the allotted time – and the nervous system habitually wakes up before the alarm goes off.

    This feature distinguishes people who have formed a strong habit of going to bed and getting up at the same time. If you wake up before the alarm rings, then you can only be happy for you-it means, most likely, that you have a stable regime and a good sleep.

  2. This is a manifestation of either generalized anxiety disorder or a problem-oriented personality type. Speaking about the alarm clock, I gave an interview in which I focused on alarm clocks.

    Getting up in the morning is a difficult task for many people. For those who can hardly get up in the morning, there are a huge number of alarm clocks — both flying, and jumping, and with a loud melody, and glowing. Candidate of Psychological Sciences, Associate Professor, somnologist Alexey Melekhin told the FAN how to choose a suitable alarm clock.

    According to the expert, any alarm clock interferes with the structure of sleep. However, sudden intervention can be stressful for the body. Melekhin recommended paying attention to light alarms.

    “It is better to choose a light alarm clock. Now there are alarm clocks that not only make a sound, but also emit a warm light. Flickering lighting allows you to avoid producing stress hormones in the morning and get up better. As for the sounds, it's not about the melody itself. The main thing is that it does not cause flinching,” the somnologist explained.

  3. I'll tell you how I feel about it. For me, it is extremely painful to wake up at the sound of an alarm clock, I wake up very abruptly and the mood is, to put it mildly, not good. Therefore, as it is written in the first answer, probably my body has already adjusted to the time when it is necessary to get up so that it is on time, not an hour earlier than necessary, and plus everything in such a way as not to hear the hated alarm bell.

  4. And what is strange is that no one has answered the question. You may not have understood.�

    I am familiar with this phenomenon and there is an assumption about:We DON'T actually wake up a second before the alarm goes off.

    I believe that the brain just fools us and when we wake up with the first sound of the alarm clock, we have a feeling, or maybe even a “memory” that we remember how we were awake during the call.

    I'm sticking with this explanation for now, as others seem less likely:

    • randomness or coincidence is possible, but in my entire life, I have more often woken up a second before the alarm clock than a minute or two, or even five. And this is directly very unlikely.

    • and, it seems to me, the body can not adjust the wake-up time to such perfect accuracy. It just seems incredible, but this is the first thought that comes to mind after the call (at least for me personally) – ” Wow, our brain is so developed that it can understand when to wake up to seconds!”.

    But then, I come back to the first explanation above – maybe our brain is not so developed, but rather the opposite is able to fool us? After all, not the first phenomenon.

  5. If a person has set an alarm clock for a certain time and wakes up for quite a long time when it rings, then his brain has already managed to adapt to this rhythm and adjust the body's biological clock for this time.�
    In more detail: in the part of the brain called the intermediate part, there is the hypothalamus and pituitary gland, which together form the hypothalamic-pituitary system, as well as the epiphysis, epithalamus, and so on. In these structures, some vital hormones are synthesized that regulate the activity of the vascular, respiratory, motor systems or other endocrine glands. In addition, the hypothalamic-pituitary system has the ability to perceive and interpret the length of daylight and provide a certain photoperiodism, that is, they adjust the biological hours of falling asleep-waking up (as well as the approximate time of eating, in many animals, and the time of reproduction, because the lengthening of daylight, for example, indicates the arrival of spring, so it's time to look for a partner). If your sleep guide is not the sun, but an alarm clock, then these structures will provide an increase in melatonin levels by the time you fall asleep (if you go to bed at a certain time every day), and by the time you wake up, the level of the hormone cortisol rises, which provides an easy rise.�

    And as for the minutes – the most complex, precisely adjusted system, which is the body, obeying its internal rhythms, cannot exactly correspond to some kind of stopwatch and provide you with an accurate awakening to the minute 🙂

    On the other hand, early arousal can also have a psychological cause. Maybe you need to wake up early in the morning because of some important business, maybe you have something exciting and important waiting for you and you are nervous about it. Maybe that's why you didn't manage to fall into a deep sleep that night and you, tormented by thoughts about this important day, try not to oversleep, say to yourself: you can't sleep any longer, we have an important day, don't oversleep! That is, your cortisol level is already elevated. We've probably all had this experience, when you wake up not a couple of minutes, but a couple of hours before the alarm goes off, fall asleep again, wake up another hour, then half an hour, go into an anxious doze for a while and then feel so broken and lost…

    In short, get some sleep 🙂

  6. My personal example. If I have an important case or event in the morning, then I don't need to set the alarm at all. The point is in the mood of the body. Setting yourself up on a subconscious level that you can not oversleep, the body itself will give you a “bell” that it's time to get up!
