​ An insomniac is someone who experiences insomnia—the inability to fall asleep or stay asleep for an adequate amount of time. Insomnia is often used casually to refer to occasional sleeplessness or a single instance of it.

Poisons are toxins that are produced as secondary metabolic products that accumulate in the host animal tissue or that accumulate in tissues of predators after ingestion of toxin-bearing prey (e.g., ciguatoxin accumulation in predatory fish such as barracuda or jack).

One of the most poisonous animals on the planet, Colombia’s golden poison frog (Phyllobates terribilis) concentrates batrachotoxin—probably from tiny beetles in its diet—and secretes it from glands on its skin. One animal produces enough poison to kill several people. (Read how poison frogs avoid poisoning themselves.)

Occasionally an animal can be both venomous and poisonous. The blue-ringed octopus, for example, is venomous when it bites with its beak but it is poisonous if it is swallowed. This is because it has a myriad of toxins in it, with the most potent (tetrodotoxin) able to be absorbed due to its very small size.

The root cause of sleep inertia is clear Sleep inertia is the result of sudden awakening during REM sleep. When you wake up during REM, you still have high levels of melatonin, causing sleepiness. The longer you sleep, the higher level of melatonin is observed during REM stage.

Sleep inertia is a physiological state of impaired cognitive and sensory-motor performance that is present immediately after awakening. It persists during the transition of sleep to wakefulness, where an individual will experience feelings of drowsiness, disorientation and a decline in motor dexterity.
