States of Consciousness

Altered States of Consciousness

• Seizures: Can induce an altered state, affecting consciousness significantly.

• Mental Conditions: Conditions like bipolar disorder lead to altered states, although not typically categorized as traditional altered states.

• Metabolism Variations: Body functions, metabolism, and alertness fluctuate throughout the day—alertness and body temperature are typically lower at night.
