Body Clock Dominance
- Our 24-hour biological clock, the circadian rhythm, significantly impacts our health and success.
- Disruptions to this clock, like artificial light and irregular schedules, can negatively affect mental and physical well-being.
Sleep's Purpose
- Sleep is a period of inactivity where essential biological processes occur, like clearing toxins and consolidating memories.
- Humans, like other mammals, naturally experience biphasic or polyphasic sleep, not just one long block.
Night Wakings
- Waking up during the night is normal, often part of a natural biphasic sleep pattern.
- Stay relaxed, keep lights low, and try to return to sleep instead of getting anxious.
