How makers stay productive

Happy to announce that after more than 2 years of sleeping at 8-9pm and waking up 4-5am, my body clock had finally settled into that routine. Maybe my circadian rhythm had switched over for some time already but I didn't realise it until I had to change my routine.

Because recently when I had to work and sleep later than usual (past 10pm), when I sleep out of routine like this, I wake up feeling like I have a hangover. 😵

Like literally:

- Head feels heavy, groggy
- Tension in the forehead
- Feeling sleepy by late morning
- Fatigue even though I sleep more for 7.5h
- Not alert unlike my usual alertness at 7.5h sleep
- Thirsty

I used to just wake up at the same time anyway on weekends even if I sleep late, at the expense of sleep quantity. Not sleeping in might be better for your heart, at least. A University of Arizona [study](https://twitter.com/steveonspeed/status/1497798849129107457) showed how for every hour your sleep shifts on the weekend, you're 11% more likely to develop heart disease. So consistent sleep keeps you alive.

But that's at the expense of sleep debt/deprivation. So to be honest, I'm not sure what's worse:

**Sleep debt or sleep hangovers**

Something to learn more about on this sleep biohacking journey!

Now that my body had settled into that 5am routine, next goal is to be able to wake up naturally on my own at 4:40am without an alarm.

Onwards!
