Sleeping 6 Hours and having a 90 minute nap during the day is called Seista sleep scheduel Bi-phasic is having 2 3. Is it normal to have a 4 hour light sleep followed by a 4 hour deep delta sleep?

I had her try it and it only shows one 4 hour block of light sleep followed by a 4 hour block of delta sleep.
Is this something that has ever been researched? I'm trying to determine if there is a correlation between the sleep patterns and her migraine severity. As our mind gets to rest, the subconscious starts to get more and more active, so even during the 3rd or 4th phase of the NREM cycle, isn't it possible that we dream?
How do shorter days influence these variables? Assuming that the body reacts on light at the end of the day to get to these times. And since the difference between when the sun goes down is about 5 hours between winter and summer would the variables also shift 5 hours? Lovely article. Thank you for the wealth of information.
I have difficulty waking up early, although every night I set out to do just that Thank you!

Understanding Sleep Cycles: What Happens While You Sleep
Thank you. Great information Submitted by Nicki on January 24, - pm. Sleeping in the morning? The first stage is a very light sleep from which it is easy to wake up. The second stage moves into a slightly deeper sleep, and stages three and four represent our deepest sleep. Our brain activity throughout these stages is gradually slowing down so that by deep sleep, we experience nothing but delta brain waves -- the slowest brain waves see "Brain Waves" sidebar. About 90 minutes after we go to sleep and after the fourth sleep stage, we begin REM sleep.
REM sleep is primarily characterized by movements of the eyes and is the fifth stage of sleep. The heart rate and breathing quickens, the blood pressure rises, we can't regulate our body temperature as well and our brain activity increases to the same level alpha as when we are awake, or even higher. The rest of the body, however, is essentially paralyzed until we leave REM sleep.

This paralysis is caused by the release of glycine, an amino acid, from the brain stem onto the motoneurons neurons that conduct impulses outward from the brain or spinal cord. Because REM sleep is the sleep stage at which most dreaming takes place, this paralysis could be nature's way of making sure we don't act out our dreams. Otherwise, if you're sleeping next to someone who is dreaming about playing kickball, you might get kicked repeatedly while you sleep. Although most dreams do take place during REM sleep, more recent research has shown that dreams can occur during any of the sleep stages.
