What is an altered state of consciousness?
Short Answer
An altered state of consciousness is a temporary condition where normal waking awareness becomes significantly modified in perception, cognition, memory, or sense of self.
Why This Matters
These states occur because various factors—including substances, meditation, sleep deprivation, or extreme environments—disrupt the brain's typical neural firing patterns and neurotransmitter balance. Different brain regions become more or less active than usual, which leads to changes in how information is processed and integrated. This demonstrates that consciousness exists on a spectrum rather than as a fixed state, revealing the malleable nature of human awareness.
Where This Changes
The intensity and characteristics of altered states vary widely depending on the trigger, individual brain chemistry, and environmental context. Some changes are subtle and temporary, while others can be profound and lasting.
