“Wake up!” Do you hear these words

“Wake up!” Do you hear these words often? If so, maybe you are not getting enough sleep. What is
sleep? Why do people sleep? How much sleep do you need?
All people sleep. All mammals and birds also sleep. Some reptiles, amphibians, and fish sleep too.
Scientists understand some of the reasons for sleep. But they do not understand everything about it.
There are two kinds of sleep in mammals and birds. One kind of sleep is Rapid Eye Movement sleep,
which we call REM sleep. The other kind of sleep is Non–Rapid Eye Movement sleep, which we call NREM or non–REM sleep. The American Academy of Sleep Medicine divides NREM sleep into three stages: N1, N2, and N3 sleep.
When people first go to sleep, they are in NREM sleep. The first stage of NREM sleep is N1 sleep. During N1 sleep, people get very drowsy. Some people have muscle twitches during this part of sleep. People are not very conscious of, or aware of, their surroundings during this stage of sleep. Brain monitors identify small, slow, and irregular brain waves during N1 sleep. The second stage of sleep is N2 sleep. People are not at all conscious of their surroundings during N2 sleep. About 45%-55% of total adult sleep is N2 sleep. Brain monitors identify large brain waves with quick bursts of activity during N2 sleep. The third stage of sleep is N3 sleep. It is very deep sleep. Brain monitors identify very slow brain waves during N3 sleep. Therefore, N3 sleep is called slow–wave sleep (SWS.)
After N3 sleep, people cycle back to lighter N2 sleep before going into REM sleep. People cycle through the stages of NREM sleep 4 or 5 times each night and enter REM sleep several times during one night. Dreams occur during REM sleep and the eyes move quickly beneath closed eyelids. During REM sleep, people and animals are paralyzed. Scientists think people enter a state in which they cannot move so they will not hurt themselves while they are dreaming.
The National Sleep Foundation in the United States says that 7–9 hours of sleep daily is best for an adult. Seven to nine hours of sleep is good for memory, alertness, problem–solving, and health. Less than six hours of sleep affects the ability to think. Getting too much sleep may not be good for people either. Too much sleep is linked to sickness and depression.
Babies need a lot more sleep than adults. A newborn infant needs up to 18 hours of sleep each day. A baby spends about nine hours in REM sleep. Five–year–olds need 11–13 hours of sleep each day. A five–year– old spends about 2 hours in REM sleep. Teenagers need 9–10 hours of sleep each day. Pregnant women need more sleep than other adults. Many people think that elderly people need less sleep than younger adults, but that is not true. Most adults do well with 7–9 hours of sleep.
Scientists are not sure of all the reasons for sleep. They know that sleep helps the body heal and grow. Sleep helps the immune system – which helps people fight disease. Sleep helps the infant brain grow. It seems that REM sleep is especially important for babies’ brain growth. It also seems that sleep is a time for processing memories. Why do we dream? Some scientists believe that dreams have a psychological purpose. Some think that dreams help organize our brains. Some think that dreams are the result of random brain activity during REM sleep.
Sleep patterns differ substantially from culture to culture. Cultures with artificial light have different sleep patterns from cultures without artificial light (like electric lamps.) In cultures that use artificial light, people usually go to sleep later at night, and they sleep through the night. In other cultures, people often sleep for two periods. They go to sleep shortly after the sun goes down. They sleep deeply for several hours. Then, they tend to wake up for several hours. Afterward, they go to sleep again for several more hours. In hunter– gatherer groups, people sleep off and on throughout the day and night.
People sleep in a variety of places, too. Some people sleep on the ground. Some sleep on mats or in beds. Some use pillows, blankets, and other bedding. But they all sleep!
Good night! Sweet dreams!

"Mifohaza!" Ve ianao hihaino izany teny izany matetika? Raha izany no izy, angamba ianao tsy ampy torimaso. Inona no
matory? Nahoana ny olona no matory? Ohatrinona ny torimaso no ilainao?
matory ny olona rehetra. Biby mampinono sy vorona rehetra koa ny matory. Misy biby mandady ary biby miain-droa, ary ny trondro koa ny torimaso.
hahatakatra ny mpahay siansa sasany ny antony torimaso. Fa tsy mahatakatra ny zava-drehetra momba azy io.
Misy karazany roa ny biby mampinono sy ny matory ao vorona. Iray karazana torimaso dia Rapid Eye Movement torimaso,
izay antsointsika hoe REM matory. Ny hafa karazana torimaso dia Non-Rapid Eye Movement torimaso, izay antsointsika hoe NREM na tsy REM torimaso. Ny American natory Academy Medicine mizara NREM matory ho dingana telo: N1, N2, ary N3 torimaso.
Rehefa matory aloha, izy ireo amin'ny NREM matory. Ny dingana voalohany amin'ny torimaso no N1 NREM torimaso. Nandritra N1 torimaso, be ny olona mahazo rendremana. Ny olona sasany dia manana hozatra twitches Nandritra ity tapany torimaso. Ny olona tsy tena mahalala, na nahalala, ny manodidina nandritra ity dingana ity ny torimaso. Atidoha Monitors iza kely, tsy mora, ary ny ara-dalàna mandritra ny N1 onja atidoha torimaso. Ny dingana faharoa, ny torimaso dia N2 torimaso. Tsy ny olona rehetra mahatsapa fa manodidina nandritra N2 torimaso. Tokony ho 45% -55% ny olon-dehibe tanteraka ny torimaso dia N2 torimaso. Atidoha Monitors atidoha lehibe hamantatra haingana onja amin'ny bursts ny asa nandritra N2 torimaso. Ny dingana fahatelo ny torimaso dia N3 torimaso. Tena tory. Monitors hamantatra atidoha tena miadana onja atidoha mandritra ny torimaso N3. Noho izany, dia antsoina hoe N3 torimaso miadana-onja torimaso (SWS.)
Rehefa avy N3 torimaso, ny olona hiverina ho maivana kokoa tsingerin'ny N2 matory alohan'ny ho REM tory. Ny olona amin 'ny alalan' ny dingana tsingerin'ny ny NREM matory 4 na in-5 isan-alina sy hiditra REM torimaso imbetsaka nandritra ny indray alina. Nofy mitranga mandritra ny torimaso REM sy ny mason'i mihidy hanao faingana ambany hodi-maso. Nandritra REM matory, olona sy ny biby dia nalemy. Mihevitra ny mpahay siansa ny olona miditra ny toetra izay tsy afaka mihetsika mba tsy hanimba ny tenany raha mbola manonofy.
The National Sleep Foundation ao amin'ny United States milaza fa ny torimaso 7-9 ora isan'andro tsara indrindra ho an'ny olon-dehibe. Fito amin'ny sivy ora ny torimaso tsara ho fahatsiarovana, Tsy Manavakavaka, ny fanalàna olana, ary ny fahasalamana. Latsaky ny enina ora ny torimaso Misy vokany eo ny fahafahana sady mieritreritra. Nahazo torimaso be loatra dia mety tsy ho tsara ho an'ny olona na. Be loatra ny torimaso dia mifandray amin'ny aretina sy ny fahakiviana.
Zaza mila be kokoa noho ny olon-dehibe ny torimaso. Ny zaza vao teraka dia mila hatramin'ny 18 ora isan'andro ny torimaso. Ny zaza mandany ora sivy REM matory. Dimy taona 11-13 ankizy mila ora ny torimaso isan'andro. A-year- dimy taona mandany ny 2 ora ao amin'ny REM matory. Ny tanora dia mila torimaso 9-10 ora isan'andro. Vehivavy bevohoka mila matory bebe kokoa noho ny olon-dehibe hafa. Maro ny olona mihevitra fa tsy zokiolona mila matory noho ny olon-dehibe mbola tanora, fa tsy izany no marina. Ny ankamaroan'ny olon-dehibe tsara amin'ny 7-9 ora ny torimaso.
mpahay siansa, dia tsy azo antoka ny rehetra ny antony torimaso. Fantatr'izy ireo fa manampy ny vatana torimaso manasitrana sy mitombo. Torimaso dia manampy ny hery fiarovana - izay manampy ny olona misy areti-mifindra. Torimaso dia manampy ny zaza hitombo atidoha. Toa matory REM Tena zava-dehibe ho an'ny zazakely 'fitomboan'ny atidoha. Toa izany ihany koa ny torimaso dia fotoana fanaovana fahatsiarovana. Nahoana isika no manonofy? Misy mpahay siansa mino fa nofy ara-tsaina manana tanjona. Misy mihevitra fa nofy manampy handamina ny atidoha. Misy mihevitra fa ny nofy dia vokatry ny kisendrasendra asa atidoha mandritra ny torimaso REM.
Matoria fakantahaka avy amin'ny kolontsaina samy hafa betsaka ny kolontsaina. Kolontsaina amin'ny mazava sy ny solon-torimaso mitovy fomba amin'ny kolontsaina tsy misy solon-fahazavana (toy ny herinaratra jiro.) Izay mampiasa amin'ny kolontsaina solon-fahazavana, matetika ny olona handeha hatory amin'ny alina tatỳ aoriana, ka natory nandritra ny alina. Amin'ny kolontsaina, ny olona matory matetika ny fe-potoana roa. Handeha hatory izy fotoana fohy taorian'ny filentehan'ny masoandro. Matory izy ireo lalina nandritra ny ora maro. Avy eo, dia mirona amin'ny hifoha nandritra ny ora maro. Ary rehefa afaka izany, dia handeha hatory indray nandritra ny ora maromaro. Ao amin'ny vondrona Mpioty hunter-, ny olona matory eny, ary amin'ny nandritra ny andro sy ny alina.
olona matory ao amin'ny toerana isan-karazany ihany koa. Ny olona sasany matory amin'ny tany. Ny sasany matory amin'ny fandriana na amin'ny fandriana. Ny sasany mampiasa ondana, bodofotsy, ary hafa ny lamba firakotra. Fa izy ireo dia matory!
Tafandria mandry! Manofisa mamy!
