Eh. Turner et al., EFFECT OF SEASON AND LIGHT TREATMENT UPON HOT FLASHES IN A PERIMENOPAUSAL SAD PATIENT, Chronobiology international, 12(4), 1995, pp. 290-297
A perimenopausal woman with seasonal affective disorder (SAD, winter d
epression) presented with a 2-year history of hot flashes occurring on
ly in the winter-time. Prospectively documented hot flashes appeared t
o follow a seasonal rhythm and a bimodal circadian rhythm. The hot fla
shes decreased with morning, but not evening, light therapy. These obs
ervations are discussed in the context of the literature regarding lig
ht's possible role in animal and human reproductive functioning.
