10 lucruri interesante pe
care nu le stiai despre
somn
1. Expunerea in timpul noptii la zgomot
suprima buna functionare a sistemului imunitar
chiar daca o persoana nu se trezeste din somn.
In plus, ciclul de somn are de suferit ca efect al
prezentei zgomotelor in prima ora dupa ce
adormim si in timpul ultimelor doua inainte sa
ne trezim.
2. Privarea de somn apare pe lista modalitatilor
de tortura facuta publica de Amnesty
International. De ce? Deoarece somnul este mai
important decat mancarea. Daca in lipsa
alimentatiei, decesul survine dupa aproximativ 2
saptamani, fara somn, o persoana nu poate trai
mai mult de 10 zile.
3. Conform unor studii femeile ar trebui sa doarma mai mult cu o ora in
fiecare noapte comparativ cu barbatii.
4. In medie oamenii dorm cu aproape trei ore mai putin decat alte primate,
inclusiv maimutele rhesus, cimpanzeii, maimutele veverita si babuinii,
acestia dormit aproape 10 ore pe durata fiecarui ciclu de somn.
5. Recordul pentru perioada cea mai lunga petrecuta de cineva fara a adormi
este detinuta de Randy Gardner. Performanta a fost realizata in 1965,
barbatul de doar 18 stand treaza timp de 264 de ore. Cazul lui a fost
documentat in detaliu devenind in timp faimos printre cercetatori.
Observatiile indica faptul ca Randy a trecut succesiv pana la terminarea
experimentului prin stari de proasta dispozitie, probleme cu concentrarea si
memoria de scurta durata, stari de paranoia si halucinatii.
6. 33% dintre persoanele care beau zilnic trei sau mai multe bauturi ce contin
cofeina au un risc mult mare de a dezvolta apneea – o conditie care se
manifesta prin intreruperea repetata a respiratiei pentru perioade scurte de
timp, iar sforaitul cronic indica prezenta acesteia.
7. Visele nu servesc un scop deosebit, ci sunt
doar produsul adaptat intersectarii intre nevoia
specific umana de a dormi si aparitia constientei.
8. Statisticile arata ca in secolul al XXI-lea 12%
dintre persoane viseaza doar in alb si negru in
fiecare noapte. Se speculeaza ca inainte de
aparitia televizorului color aproximativ 75%
visau doar in alb si negru noapte de noapte.
9. Inregistrarea atenta si continua a activitatii creierului uman in timpul
somnului a dus la descoperirea somnului REM (rapid-eye-movement) nu s-a
realizat pana in anul 1953 pentru ca cercetatorii nu vroiau sa faca risipa de
hartie.
10. Visele REM sunt caracterizate de un fir narativ bizar, in timp ce cele non-
REM sunt lucide si repetitive, avand foarte putine imagini distincte pe
parcursul lor. Acestea din urma sunt rezultatul unui gand obsesiv pe care o
persoana l-ar putea avea legat de un detaliu mundan, precum faptul ca uitat
telefonul mobil undeva sau ca am uitat sa scoata fierul de calcat din priza.
