I’d rather look back at my past and say, ”I can‘t believe I did that!“ instead of saying ”I wish I did that.

How do you actually build the habit of waking up early?
I’ve always wanted to wake up early in the morning and go for a walk, but somehow I keep failing to make it a habit
Some days I feel motivated, set an alarm, and plan everything. But when morning comes, getting out of bed feels like the hardest part 😅
For those of you who successfully built this habit, what actually worked for you?
I’m looking for real advice, not just “be disciplined.”

What is a simple evening boundary you set that made your mornings ten times easier?
Morning routines get all the credit on productivity forums, but 90% of how you feel when waking up is determined by the three hours before you sleep. Creating a clean buffer between dinner and bed, putting the phone in another room by 9:30 PM, or just taking ten minutes to wipe down the kitchen counter changes your entire morning headspace. What is the low-effort evening rule you stick to that prevents morning grogginess and chaotic starts?

Here's a guide to better understand what actually influence staying asleep based on research. This is a completely different area than what influences sleep latency (falling asleep faster) and focuses mostly on Wake After Sleep Onset. I broke this into 5 main areas: nutrition, supplements, exercise, environment, and demographics. Hope you find it useful overall!
I added a plain english explanation column for each row and short definitions to start which I hope helps make it easier to understand each factor. All sources are linked at the bottom.
I know the tables are difficult on mobile so I take all the data to make it into a free tool that lets you explore the data in a more visually appealing way. Here's the page if interested: kygo.app/tools/staying-asleep-factors
Acronyms:
WASO - Wake After Sleep Onset
PSG - Polysomnography
SMD - Standardized Mean Difference
RCT - Randomized Controlled Trial
SWS - Slow Wave Sleep
AHI - Apnea-Hypopnea Index
SWSD - Shift Work Sleep Disorder
HPA - Hypothalamic-Pituitary-Adrenal (axis)
