These ratings were matched with local measurements of atmospheric pressure, cloud cover, and temperature. Several alternative second order differential equation models were fit to the data in which mood oscillations in RCBD were allowed to be linearly coupled with daily weather patterns.
The modeling results were consistent with an account of mood regulation that included intrinsic homeostatic regulation as well as coupling between weather and mood. Models were tested first in a nomothetic method where models were fit over all Mood and weather and fit statistics of each model compared to one another.
The best-fitting within-individual model for the largest number of individuals was also the best-fitting nomothetic model: But this model was not the best-fitting model for all individuals, suggesting that there may be substantial individual differences in the dynamic association between weather and mood in RCBD patients.
Heterogeneity in the parameters of the differential equation model of homeostatic equilibrium as well as the coupling of mood to an inherently unpredictable Mood and weather. Patients with RCBD, who by definition, experience four or more major affective episodes per year [ 4 ], represent an important population for studying a potential relationship between mood and weather because significant mood changes occur over a relatively short interval of time.
From a theoretical standpoint, the evaluation of a possible relationship between weather and mood would contribute to our knowledge of mood regulation and dysregulation. Clinically, the severity of RCBD and its challenging management warrant the effort to define the environmental factors that might contribute to the frequent shifts observed in the mood of these patients.
This would allow the estimation of short term prognosis, the anticipation of situations of increased vulnerability, and the design of secondary and tertiary prophylactic measures [ 5 ].
The present study examines the relationship between daily self-reported mood ratings from a sample of RCBD patients and three weather variables: A relationship between affective states and temperature has been suggested in multiple studies, although the relationship has not been replicated consistently [ 65 ].
Sky cover was chosen because of the antidepressant effect of light and its potential for stabilizing or destabilizing RCBD patients depending on the timing of the exposure [ 7 ].
Evidence that atmospheric pressure is involved in mood regulation is less direct, but there are indications that atmospheric pressure affects neurotransmitters implicated in mood regulation.
Temperature Neurotransmitters involved in mood regulation are also involved in thermoregulation. It has been shown that injection of either dopamine or 5-HT in a small dose causes a fall in core in rats at about 17 degrees Celsius [ 8 ].
During cold exposure, the levels of NE increase many-fold [ 9 ]; NE is released from peripheral nerve endings and exerts thermoregulatory response through alpha adrenergic receptors on smooth muscles and beta adrenergic receptors on skeletal muscles.
According to them, there was an increase in NE or DA in response to the cold wind stress and these two affect the level of other amine levels. They noticed a difference in the response to the same dose of MDMA at different temperatures. It was seen that MDMA produced a greater increase in dopamine levels at higher temperatures than at lower temperatures.
Also, MDMA produced a greater thermogenic response at higher ambient temperatures as compared to lower ambient temperatures. Finally, there is some recent neuroimaging evidence of the effect of temperature on affect.
Sky Cover One reason to suspect sky cover as a potential predictor of mood regulation is the evidence from seasonality. Changes in photoperiod are followed by changes in temperature, sunlight, humidity, etc. Winter depression and photoperiodism [ 15 ] are phenomena of which many people are aware.
However, it is less widely known that the majority of incidents of depression are during spring, and successful suicides are more frequent in spring than in other seasons.
In fact, one of the most highly replicated findings in psychiatric epidemiologic research is the seasonal spring peak in suicide [ 16 ], an ultimate and tragic result of mental illness.
A peak in spring was reported for depression exacerbation, admissions for depression, and ECT use [ 171819202122 ]. Admissions for bipolar depression also peak in April [ 2324 ]. Photoperiod, changes in photoperiod, and light intensity have been proposed as possible driving forces for peaks of suicide and depression [ 25 ].
However, upon careful scrutiny, the peak times of suicide occurrence April and May, reviewed by Altamura et al. Atmospheric Pressure There are several indirect reasons why atmospheric pressure may play a role in mood regulation.Hot days certainly take a toll on our bodies, but they can also test our tempers, experts say.
Many people feel a little hotheaded when the mercury rises, said Nancy Molitor, an assistant. By Dr. Mercola. Weather can be sunny, stormy, dreary or unpredictable but then so, too, can your mood. The way you feel on any given day may actually be intricately tied to the weather forecast in ways science is only beginning to understand.
Weather and mood are linked in some research, but not in others.

Your Name. Weather is one particularly large indicator of how your mood is going to turn out for the day, and if you have ever thought that the weather seems to be an apt metaphor for your mood (a pathetic fallacy as it is known in literature) then most likely the link is there indeed but the correlation is actually working the other way around.
