Frequently Asked Questions about Dolphins
Why do Dolphins experience severe insomnia?▼
Dolphins are characterized by nocturnal hyper-arousal. Their blood pressure and cortisol do not decline in the evening as they do for other chronotypes, keeping their brain alert.
Should Dolphins take melatonin supplements?▼
Dolphins should avoid high-dose synthetic melatonin as it can cause daytime grogginess. Calm biological agents like L-Theanine, Magnesium Threonate, and dimming lights 2 hours before bed are much more effective.
