All Time Sleeping Average: (Target) 7h30m / day (Actual) 7h25m / day (105 day average)
3 Day Sleeping Average: (Target) 7+h / day (Actual) 5h50m / day (7h, 6h69m, 3h28m)
I keep talking about sleep debt, but I never touched upon the topic of sleep reserves.
Using personal finances as an analogy, not only does one have to eliminate / minimize debt, one also has to have emergency funds on hand to deal with emergencies.
One “emergency” was going to the Muse concert yesterday at the Asia World Expo, which made me go to sleep at 2:46 am and wake up at 6:15 am, before having to take a nap until 7:00 am since I just didn’t have the energy to wake up. And all of this made me groggy and also feel sick.
Which is also another important reason why sleep reserves is important. Once short term sleep debt accumulates too much, I easily get sick. And once I get sick, it requires much more sleep for me to recover than just repaying the sleep debt until my average sleep per day is 7 hours 30 minutes (which is my target).
And that doesn’t make any economical sense whatsoever since every hour of sleep missed could rack in much more hours of sub-optimal mood and wellness.
So what’s the game plan?
On the long run, I’d like to boost my long term sleep average to 8 hours since that ensures all sleep debt in short term or long term is thoroughly cleared.
In the short run, I will measure my 3 day average sleep time and make sure the 3 day average never drops below 7 hours, since “Athletes build up sleep reserves or defecits over 1-3 days” and “Medical evidence suggests that for optimum health and function, the average adult should get seven to nine hours of sleep daily“.
