Just watched the end of a TV program where it said
the most natural time for giving birth is between 2am and 4am and the most common time to meet your maker is the same time, is there any correlation with the dreaded Wake you up at 1.30am, are there any night shift workers out there who have and suffer CH, do they suffer about that time whilst working

The most common time for nighttime hits is about 90 minutes after falling asleep - coincidentally at the onset of REM sleep.

The most heart attacks in a given day of each year will happen this Sunday.

Brew, I don't quite get what you're meaning.

Does "coincidentally" imply
     a) at the same time (with a possible cause and effect connection)
or
     b) by chance, at random (without cause and effect connection)

I've searched several dictionaries and some give a) others b) and some give both definitions.

BTW, I think the onset of REM sleep changes the mix of neurotransmitters in such a way that favors the onset of an attack.

ASG - I meant merely that they occur at roughly the same time. I think there is a definite connection between the two, and tying it back to the original post, it shouldn't matter what time one goes to sleep, only what time one enters REM sleep.

That might be true for clusterheads in general (not sure). For me, the most common time to get hit is around 5:30 am.  REM sleep tends to get longer and more intense as the sleep cycle continues. The first few days of the cycle, there is one right before dawn. Then they gradually spread, until I am getting them 90 minutes after going to sleep, and through out the morning.

I'm a 9 to 5'er, but pm to am.  When preventatives not well used, common times still 90 minutes after falling asleep, about every 90 minutes to 2 hrs thereafter, and just before waking, no matter the time of sleep, which are mornings to afternoons now.  

Take melatonin -- it gets ya thru the REM sleep ..  For me it stops those little buggers during the night...

I spent 35 years on a rotating work schedule. Different shift each week. Days, swing, days, graveyard, repeat.
When I was on day shift, 8am to 4pm, the attacks would come when I slept at night. When I worked swing shift, 4pm to midnight, I usually slept from about 3am to 10am. That's when the attacks happened. When I was on the graveyard shift, midnight to 8am, I usually slept 2pm to 9pm and got the attacks then.
During the hours I was working I can only remember getting an attack twice in all those years.
Relaxing after a stressful work day, no matter which shift, and REM sleep mode was always the attack time.

Why, daylight savings?


For what it's worth, my headaches tend to occur about 90 min. into sleep with the REM cycle.  Some are triggered by other means, but mostly by sleep.

I kinda wondered about that, too. If it were daylight savings, we'd get the most in the fall, when we set the clocks back, when we actually get 25 hours in one day. Right?

Quote:

The research, based on heart attacks in Sweden, concluded that the chance of a heart attack goes up during the first three weekdays after the springtime shift to daylight saving time, possibly because of sleep deprivation. But on the autumn Monday after clocks go back and people can get an extra hour of shuteye, the heart attack risk declines.

not for me either, in my current cycle it begins between 7:30 - 8:30pm every night for 2 hours.

Okay, I get it. I did say "most common." Not "unanimous."
