Forskningsinteresser

Jeg er opptatt av om og hvordan organismen reagerer på mørketid, midnattssol og nordlys. Dessuten kan mørketid, midnattssol og nordlys ha betydning for effekten av aktivitet/trening  og prestasjoner? Kan det være lurt å legge trening til ulike tider av døgnet for å få best effekt? Kan det spille noen rolle om personen/utøveren er et såkalt A-menneske eller B-menneske (ulike chronotyper) for effekten trening og aktivitet har på helse og prestasjon?
