Difference between Sleep and Slumber

Key Difference: Sleep and slumber are synonymous. Both refer to a state of partial or full unconsciousness. During this period, the body and mind are rejuvenated and are restored. Slumber is sometimes used to refer to specifically a light sleep or a doze.

  1. The first stage is generally defined as the one in which a person closes his eyes but still does not feel like he has slept.
  2. In the second state, irregular periods of muscle tone are mixed with the relaxation of the muscles. These are accompanied by a slow heart rate and then a decrease in the body temperature. This stage can be referred to light sleep.
  3. The third stage is also known as a delta sleep. This is a stage of deep sleep. Awakening from this stage get be frustrating or disorientating.
