Den naturlige d\u00f8gnrytme<\/strong><\/h2>\n\n\n\n

For flere tusinder \u00e5r siden, boede mennesket i huler. Det var sollyset, der bestemte m\u00e6ngden af aktivitet. N\u00e5r m\u00f8rket faldt p\u00e5, blev huler og grotter indtaget, og der befandt mennesket sig, indtil morgensolens str\u00e5ler atter kastede lys i grotten.<\/p>\n\n\n\n

Udgangspunktet for en god s\u00f8vn, var til stede. Solnedgangen gjorde kroppen klar til hvile, og de k\u00f8lige grotter muliggjorde et naturligt fald i kropstemperaturen. Ingen kunstige, forstyrrende elementer bragte rod i det biologiske ur. Det bet\u00f8d, at d\u00f8gnrytmen i store tr\u00e6k var den samme hver dag.
<\/p>\n\n\n\n

Kunstigt lys: Genial opfindelse eller fjende?<\/strong><\/h2>\n\n\n\n

Efter opfindelsen af elektrisk lys begyndte menneskets d\u00f8gnrytme at blive forstyrret. I l\u00f8bet af 1800-tallet overtog gl\u00f8dep\u00e6ren de tidligere primitive lyskilder som t\u00e6llelys, petroleumslamper, stearinlys og \u00e5bne ildsteder. Det bet\u00f8d, at mennesket fik adgang til kunstigt lys d\u00f8gnet rundt. Nattens timer, der ellers var reserveret til hvile og s\u00f8vn, kunne nu bruges produktivt. <\/p>\n\n\n\n

P\u00e5 denne m\u00e5de blev d\u00f8gnets rytme fleksibel, og aften- og natarbejde blev gjort muligt.<\/p>\n\n\n\n

Flere \u00e5rsager gjorde at gl\u00f8dep\u00e6ren snart blev den foretrukne lyskilde, bl.a. lugt og sodgener. Men ulempen ved gl\u00f8dep\u00e6ren var det store energiforbrug. Det har f\u00f8rt til udviklingen af nutidens LED-lys og elsparep\u00e6rer.<\/p>\n\n\n\n

L\u00e6s ogs\u00e5:<\/strong> Lejring og respiration<\/a><\/p>\n\n\n\n

Hjernen bliver snydt<\/strong><\/h2>\n\n\n\n

De moderne lyskilder har endnu st\u00f8rre konsekvenser for menneskets s\u00f8vn. LED-lys og lyset fra elsparep\u00e6rerne er modsat traditionelle gl\u00f8detr\u00e5dsp\u00e6re ikke lyskilder, der lyser j\u00e6vnt i hele farvespektret.<\/p>\n\n\n\n

Sparep\u00e6rernes lys og LED-lyset er meget intenst i de gr\u00f8nlige og bl\u00e5 farver og forskere p\u00e5peger, at specielt disse lysformer udfordrer den gode nattes\u00f8vn. Mennesket er nemlig skabt til at reagere p\u00e5 det bl\u00e5lige morgenlys, der nulstiller vores biologiske d\u00f8gnrytme, og det svindende r\u00f8dlige aftenlys, der signalerer, at det er tid til at sove.<\/p>\n\n\n\n

De gr\u00f8nlige og bl\u00e5 nuancer, er de farver som \u00f8jets ganglieceller er s\u00e6rligt modtagelige overfor.  D\u00f8gnrytmen styres af gangliecellerne i \u00f8jets nethinde. De registrerer lys og sender signaler videre til hjernen, der b\u00e5de h\u00e6mmer s\u00f8vn-fremmende nerveceller og aktiverer nerveceller, der hj\u00e6lper os med at holde os v\u00e5gne.<\/p>\n\n\n\n

I det store hele betyder det, at n\u00e5r mennesket sidder foran LED-tv’et, smartphonen eller computersk\u00e6rmen om aftenen, bliver kroppen badet i lys, der fort\u00e6ller hjernen, at det er tid til at st\u00e5 op. <\/p>\n\n\n\n

Derfor h\u00f8rer vi mere og mere om, hvor skadeligt det kan v\u00e6re at bruge smartphonen lige inden sengetid eller m\u00e5ske i sengen.
<\/p>\n\n\n\n

Skab pr\u00e6missen for god s\u00f8vnkvalitet<\/strong><\/h2>\n\n\n\n

At lys p\u00e5virker kroppen, har v\u00e6ret kendt l\u00e6nge. Men at LED-lys og lys fra sparep\u00e6rer i den grad har en direkte negativ p\u00e5virkning p\u00e5 s\u00f8vnen, er knapt s\u00e5 kendt. Det b\u00f8r dog v\u00e6re en faktor, der prioriteres i arbejdet med sengeliggende mennesker.<\/p>\n\n\n\n

Mennesker der ikke selv kan v\u00e6lge om der er lyst eller m\u00f8rkt der, hvor de sover, har krav p\u00e5, at de der yder pleje og omsorg for dem, er kl\u00e6dt p\u00e5 til at skabe pr\u00e6missen for en god s\u00f8vnkvalitet.<\/p>\n\n\n\n

Dette g\u00f8res blandt andet ved at minimere det bl\u00e5 lys inden sengetid, og s\u00f8rge for m\u00f8rke om natten. Er der brug for lys om natten pga. m\u00f8rker\u00e6d skal lyset v\u00e6re gulligt.<\/p>\n\n\n\n
