I have no idea what’s going on here, but after reading what Nice2knowU wrote, I think it could be because the cortisol kicks in early for you. Which comes with amygdala activation, but after you get on with your day, this activity gets balanced, so the cortisol becomes fuel energy instead of stress.
Are you also getting sunlight earlier when you wake up earlier? It brings that balanced effect to cortisol.
On the other hand, I think your body would accustom to any schedule you prefer, specially if you have a good morning routine. But yeah, many people are early risers, and wether you are or not, sleepyness always comes at noon so it’s better to wake up early. But 8am is a good time.
You just listened more time to the field so it affected you more. The effects of the field don’t disappear just cause you stop the track midway or re-start it. So think of it as if you listened to it 1.5x, not just once. Or were under the effect of the field for 18 mins, not 12.
Nope, those 6 mins affected you. By the way some people are very energy sensitive and don’t even play fields once. They play like a min and then have to stop. It pays off to be cautious rather than greedy with fields.
