Eivind Schjelderup Skarpsno

Om

Eivind Skarpsno (1990) er Toppforsker (1183/Professornivå) ved Institutt for Samfunnsmedisin og Sykepleie og leder av forskningsgruppen ASaP: Aktivitet, søvn og smerte. Forskningen hans er særlig rettet mot å forstå hvordan lite søvn og søvnproblemer påvirker funksjon og helse, samt hvordan man kan man kan øke forståelsen for og bedre støtte personer som sliter med søvnplager. Han er en hyppig brukt formidler i media, og har bidratt i en rekke oppslag, inkludert flere førstesider i VG samt innslag på TV og radio. I tillegg står Skarpsno bak forskningspodkasten Årsak-Virkning.

Skarpsno leder arbeidspakken Arbeidstid, søvn, og helse i STUNTH prosjektet som undersøker sammenhenger mellom arbeid og helse blant ulike ansattegrupper i sykehus. Han er også nestleder for programområdet Helse- og Velferdsteknologi, et samarbeid mellom NAV, Helse Midt-Norge og NTNU som skal styrke forskning og kompetanse på områder med særlig kunnskapsbehov i NAV- og helsetjenestene.

Forskningsinteresser

Forskningen fokuserer på samspillet mellom søvn, helse og funksjon gjennom livsløpet, med særlig vekt på følgende områder:

Søvn og smerte – hvordan søvnmangel og søvnforstyrrelser påvirker smerteopplevelse
Søvn, utmattelse og mental helse hos ungdom – betydningen av søvnvaner for psykisk- og somatisk helse og daglig fungering
Individuelt tilpasset søvnbehandling ved kroniske smerter – utvikling og evaluering av målrettede tiltak for bedre søvn og livskvalitet
Helse- og velferdsteknologi – bruk av digitale løsninger og sensorteknologi for å måle og forbedre søvn og helse
Arbeidstid, skiftarbeid og helse – hvordan arbeidstidsordninger og ulike arbeidsbelastninger påvirker søvn, helse og risiko for sykdom
