From the sounds of it, you have an inverted cortisol/melatonin pattern. You can take an ASI test for this to confirm it. If that's the case, you can do a few things such as very bright light exposure in the morning, preferably from sunlight, and... (more)

They're going to be correlated to circadian rhythms. They can spike depending on stress levels, or fasting. If you have prolonged stress issues, they can get flipped around and you'll wake in the middle of the night instead of morning. They're... (more)

Cortisol regularly fluctuates in healthy individuals. It rises and spikes at sunrise, spiking slightly less again at noon and then decreases for most of the evening as shown below: My question to you guys is if any of you guys have tried eating... (more)

It's simply an internal clock thing for me, I believe. We don't ever set an alarm, but we're usually awake by 4AM. Granted we go to bed earlier than many. The darkness is not an issue for us, neither lack of it when retiring early in the summer,... (more)

I use f.lux on my macs to change the blueish screen glow to something warmer, which supposedly screws less with your circadian rhythms. I'd love it if there were something similar one could do for occasional television watching. Does anyone know... (more)

For some reason, I tend towards being awake at night. I've tried being awake in the day, and I don't like it as much. Also, for some reason, I sleep better during the day, although at least it's possible for me to sleep at night, now. If I'm... (more)

Since early childhood, I've never been very successful at living a day-adapted schedule. Going to bed at dawn and waking up at noon is the natural rhythm I've always fallen into, given the chance. I sleep just fine during the day, and have never... (more)

I entirely take the point about the idea that DSPS-symptoms might somewhat result from individuals merely having differential responses to factors that are (largely) unavoidably in the modern environment, but (largely) absent in the paleo context.... (more)

Nightlife? Everything in moderation, correct? You'll be fine. You've got a few buckets to consider: Eating right, exercising right, some sun, getting your sleep, and a couple other minor ones. If you're hitting it hard night after night, you might... (more)
