Why do I wake up at 3am?

it can be due the drinking fact or it s related to spirit things if you heard about witching hour ...

The brain is highly active at night, transforming short-term memory into long-term memory and carrying out repair and regeneration, and it depends on a steady supply of energy to do these tasks. When you sleep at night your body goes into a fasting state. In order not to deprive the brain of the food it needs for energy, the body compensates by gradually raising cortisol, an adrenal hormone. Cortisol stimulates the body to release or create glucose to supply the brain with energy during the night-long fast. Chronic low blood sugar, however, throws a kink in this process. People with hypoglycemia tend to have difficulty making the right amount of cortisol at the right times of the day or night. They also have blood sugar levels that spike and then crash throughout the day. If they go too long without eating they experience lightheadedness, irritability, shakiness, a spacey feeling, and other symptoms that signify the brain is not getting enough glucose. In these cases, not only does blood sugar drop too low during the night, but the adrenal glands don’t produce enough cortisol to keep the brain fueled. In response, the body sounds the emergency alarm by releasing “fight-or-flight” hormones. These stress hormones raise blood sugar back to a safer level. Unfortunately, they also raise stress, which can cause anxiety or panic in the middle of the night. Hence the waking up at 3 a.m. and not being able to fall back asleep.

Because your body doesn't produce enough melatonin to keep you asleep throughout the night. When you wake up at three am many days in a row, it turns into a sort of habit for your body.

I wake up at 3 am from anxiety usually. I practice mindful meditation and calm breathing. After a nice cup of tea I am usually able to sleep again!

It is possible that you might have anxiety for the next day, or are feeling uncomfortable in your sleep. Many reasons can be a cause of waking up at odd times during a normal sleep patter. It would always be better to get a suggestion from a certified personal instead of assuming things.

Because anxiety makes me exceptional self-aware, and I tend to react to every little change in my body. I think this also involves my subconsciousness, which is reacting and waking me up during sleep.

I used to wake up often between 3-4am. I think the main reason is based on pure biology. There are two hormones that help us with the sleep/awake cycle. One is melatonin (promotes sleep) and the other is cortisol (promotes being awake). Both of these are tied to a complex system of 'clocks' inside your body and when you are stressed, or anxious or have other health issues - these clocks get out of sync. So your body is producing Cortisol at an inappropriate hour. The best way to fix, from my research, is to help regain your health and manage your stress/anxiety and emotions. This also involves building up your circadian rhythms - eating/sleeping in a consistent way each day and not staying up too late at night nor sleeping too much during daylight.

Its two fold, your cyclical cycle for sleep is programmed to that time, which is why you wake up at a certain time consistently. Also, back in "Olden Times" we as a species used sleep in 2x Four Hour segments. After the first four, wed wake up and be up for a bit (1-3 hrs) and hang out or have a chat with a neighbour. Then go back to sleep for another few until sunrise. History does tend to repeat itself more than you realize :)

I wake up at 3am often because I cannot sleep. I open up 7 cups of tea, and try to take as many general requests as I am able to handle.

Waking up at three am is the worst. I often find myself awake at three am because I can't shut my brain off. I would have fallen asleep earlier that night, but then without me consciously realizing it I wake up. My mind just starts running in list of things I have to do, things I've done wrong, and whatever else is pressing on my mind. My mind will not be quieted, it runs without me consciously steering my thoughts. I can lay for hours thinking without realizing I should be asleep. That's why I wake up or find myself awake at three in the morning.
