Dolphin Sleep Type

Your sleep style is the 'Dolphin' sleeping with half-brain. Dolphins sleep with only one hemisphere of brain while still swimming, and you, too, recover efficiently in short time even with light sleep. 6 hours is fine, surprisingly maintaining condition even on short sleep.

You use sleep efficiently. Lighter rather than deeper, but that light sleep is enough recovery. Often wake naturally before alarms, and can switch immediately to active mode in the morning. That efficiency lets you have long days on short sleep.

The core of Dolphin Sleep is 'guard awareness.' Not falling deep, you respond quickly to surrounding changes. Instinct to wake immediately upon sensing danger — that's the dolphin sleep feature. So you wake to small movements of someone sleeping next, or sounds from next room. That sensitivity is both weakness and strength.

The downside — only light sleep means deep recovery is lacking. Insufficient fully-unconscious time accumulates fatigue. Sometimes consciously create environments to fall deep. White noise, eye mask, earplugs — tools that block external stimuli help. Light and deep sleep in balance — the Dolphin Sleep's wisdom.
