A positive relationship between ambient temperature and bipolar disorder identified using a national cohort of psychiatric inpatients

Increased relative risks of bipolar disorder admissions were associated with the increasing trends of temperature over 24.0 °C (50th ‰), especially for adults and females, and the highest daily diurnal temperatures above 30.7 °Cs had the greatest risks ofipolar hospitalizations.


The main objective of this study was to document the relationship between the seasons and the occurrence of Major Depressive Disorder. With the changes of the climate, a study was conducted to

The influence of sunlight exposure on hospitalization in emergency psychiatry

Excessive sunlight exposure may exert a fundamental role on psychopathological conditions presumably affecting biological vulnerability and a better understanding of its effect on the course of bipolar and other psychiatric disorders may assist in tailoring the adequate treatment for patients resulting in a shorter stay within hospitalized settings and abetter treatment response.

Bimodal effects of sunlight on major depressive disorder.



Admission rates of bipolar depressed patients increase during spring/summer and correlate with maximal environmental temperature.

Increased environmental temperature may be a risk factor for evolvement of major depressive episode in patients with bipolar disorder with psychiatric co-morbidity, at least in cases that necessitate hospitalization and at the examined geographic/climatic region of Israel.

Changes of clinical pattern in seasonal affective disorder (SAD) over time in a German-speaking sample

An increase in awareness of fall-winter depression in the last decade by both doctors, who referred patients, as well as patients or the entire population must have caused patients to sign up for light therapy at the Viennese SAD clinic because of having heard about the atypical symptom profile.

The actuality of seasonal variation in mood has been documented thoroughly by both retrospective and prospective studies, and the most extreme form of this disposition, SAD appears to be a relatively common disorder.

Seasonal variations in hospital admissions for affective disorders by gender and ethnicity

The reverse seasonal pattern for depression and mania suggests a maladaptive response of vulnerable individuals to specific functions of seasons, and specific seasonal effect for affective illness was evidenced by the non-existence of seasonality in other psychiatric disorders.

Psychiatric disorder, hospital admission, and season.

No other diagnoses, overall, showed seasonality, although personality disorders, drug addictions, and transient situational disturbances exhibited trends similar to neurotic depression for certain age and sex groups.
