This ray hunts at night
and spends days with friends.
It works out all right
that fish never sleep.
Although fish never sleep, peaceful and restful fish help people wind down to catch ZZZs, escape stress, avoid bedtime anxiety and ward off sleep-deprivation ills.
Do Fish Sleep? According to NOAA, fish behavior, habits and position show they remain half-awake. EEG equipment records electrical brain activity to calculate the percentages of time spent asleep and awake.
Blast Shield? “Eyes wide open” applies to fish. Sharks have eyelids. Two of them are fixed. They do not close. A clear nicitating membrane rises behind the lower lid of some sharks. It offers eye protection during attacks.
Fine Focus? Other fish have no eyelids. Like crustaceans, insects, snakes and spiders, their eyes stay open. Bullfrogs have three eyelids to moisten, clean and camouflage their eyes. They hibernate rather than regularly sleep.
Perfect Getaway? According to Pizard's GURPS Miscellanea, Basking Sharks may hibernate. Cave resting spots have less salt and more oxygen. Sharks may move into caves for the oxygen high of recreational oxygen bars.
Perpetual? Active fish breathe with water flowing over gills. Some resting sharks work to pump water by mouth to their gills while inactive. Other sharks and rays oxygenate with spiracles, external respiratory openings.
Quality Control? Were they to breathe through the mouths under their heads, bottom fish would suck sand and grit from the ocean floor. This would impede rest. Spiracles aid bottom dwellers, not deep-water mantas or sharks.
Flower Power? Sleep and rest benefit people and animals. Rest and relaxation improve productivity, memory and health. Fish do not need unnatural scents or flavorings for a relaxing wind-down experience.
Avoid Bedtime Anxiety
Dopamine High? Sleep-enhancing efforts can lead to unhealthy obsessions. Checking or bumping into monitoring apps or equipment in bed interrupts slumber. Sleep tech may heighten awareness of regular behavioral patterns.
Takeaway? Feedback and measurements of noise, movement, deep sleep spans or deficit percentages can be inaccurate. Disruptions from wearable or nearby tracking devices may worsen sleep hygiene and impair data.
Everything Clicks? The JCSM presents an abstract about Orthosomnia: Are Some Patients Taking the Quantified Self too Far? This preoccupation with wearable self-diagnosis tools for shut-eye perfection can disrupt the calm.
Super Natural? Sleep is regulated naturally by a circadian biological clock. Sleepiness, wakefulness, hunger and other day or night functions largely track light and darkness. Environmental and genetic factors also play roles.
Lunar Cycle? Physiology determines sleep-wake homeostasis, or the balancing of sleep needs and intensity with biochemistry. Rhythms are polyphasic (multiple), monophasic (singular) or biphasic (two periods).
Mapped Out? Animal resting cycles typically are polyphasic. Humans are split. Monophasic people sleep only once within a 24-hour period. Others follow biphasic schedules with two regular sleep periods over this time.
Contemplate Life Patterns? Diurnal round stingrays become active in daytime. Nocturnal Manta Rays power up at night. Crepuscular Great White Sharks tend to gain momentum during dawn or dusk hours.
Rebound Sleep. This increase in rest helps fish and people offset deficits. It is common after periods of deprivation or disruption. Storms, migrations, mating and parental activities often interfere with regular habits in the wild.
Safe Resting Spots? While removed from active swimming and hunting activities, some fish hide under rocks, behind plants or buried in sandy ocean banks or bottoms. Others use group safety; guards oversee those at rest.
Sticking Power? Spines are present on many fishes' dorsal, pectoral, anal and pelvic fins. These provide protection. Some fish use their fin spines to lock themselves into crevices, so predators cannot pull them out.
Rain Dates? While resting, reactions to stimulus may become sluggish. Protective schools, calm waters and repetitive movements may relax constant swimmers. Mama Ray describes trance-like tonic immobility, or “hypnosis”.
Don't Let Your Guard Down. During sluggish periods, fish watch their surroundings, remaining alert for opportunities or problems. Agile sharks and rays quickly respond to escape, exterminate or ward off perceived threats.
A Misnomer? The Japanese Sleeper Ray disappears under the sand. This little electric ray lies in ready wait. Should something or someone interrupt its peaceful moment, it is fully prepared to pack a strong electric punch.
Synaesthesia? Rare people sense unusual perceptions; i.e., seeing sounds, tasting colors or smelling textures. It is hard to know what fish experience at their acute sense levels. Senses humans do not share add stumbling blocks.
Stoned Fish? Fish do not feel weed's psychoactive effects, per Aquaculture Researchers in Lebanon Effect of cannabis oil on growth performance, haematology and metabolism of Nile Tilapia Oreochromis niloticus.
Substitutes? Associated with powerful maneuvers, stingrays and sharks are active. However, these cartilaginous beings connect with the water element. They share the restful sleep alternatives of their bony cousins.
Fish Help People
Island Time? Aquariums are conducive to sleep. They make good substitutes for beach getaways. Fish do not need the living space or care of most pets. A mix-and-match variety gives easy lessons about life in water.
Pastel Play? According to Aquarium Adviser, The Benefits of a fish tank at home are health, wealth and luck. Like Chinese Feng Shui, fish bring harmony to people with their coloration, decor, arrangement and location.
Therapeutic Fish? These quiet creatures listen and respond to outside attention 24/7. Hyperactive children and tense or insomniac adults may decompress with the hypnotic, sleep-inducing gracefulness of fish motion.
Drawing Inspiration? Fish are disciplined, tireless, serene and instinctive. Their movements may reduce anxiety, stress, blood pressure and heart rate. Productivity, concentration, motivation, positivity and focus may improve.
Beauty and the Elements? The calming sounds and rainbow of hues in the laid-back, aquatic world provide a soothing break for healthy living. Little Ray's video below is a tranquil peace offering for friends, days and nights.
Take Me to Your Leader! It is not necessary to wait until lights out or belly up to possible risks in oxygen bars. Little Ray's fish insights have no toxic side effects. There is no worry of allergic reactions or complications.
Naturally Sunny? Desire to learn about stingrays and sharks may become “addictive”. The quiet video is danger-free. The theme is not from a Little Ray book. Readers will recognize illustrations from his tales of the deep.
VA-VA-VOOM Service? The transcript for the video below reads as follows:
We will not count sheep. They might fall to sleep. We will count stingrays. They're up nights and days. (21 seconds)
