This shift not only affects when you feel ready to sleep but also impacts your morning wake-up time, resulting in a cascade of negative effects on alertness and overall functioning. The delicate balance between melatonin and cortisol is thrown off, illustrating the profound connection between light, sleep, and hormonal regulation.
