Allergies Affect Mood

Seasonal allergies have a definite impact on mood, often increasing the risk of depression, states research. 
Dr. Paul Marshall, neuropsychologist at Hennepin County Medical Center in Minneapolis, Minnesota comments that a visit to an allergist  could actually mean the likelihood of depression affecting a person.Although allergies do not cause clinical depression, they cause mood changes that result in the physiological symptoms of mild depression, leading to overall feelings of sadness, lethargy, and fatigue. And those who already suffer from depression, their symptoms worsen with the allergy. 
An allergic  reaction brings about the release of cytokines in the body that brings on the feeling of being ill and ‘mentally drained.’ Earlier studies, led by Marshall, had proved that allergies triggered off by pollen caused fatigue and mood changes and slowed down cognitive processing. 
Dr. Teodor Postolache at the University of Maryland, in his study, established the link between tree pollen  depression and suicide, and this occurred more in women than in men. 
Other research concludes that low moods could be circumstantial, caused by the sneezing or sleeplessness or even by the medication taken for the allergy. And although these factors could lead to depression, they are not its direct cause. Antihistamines and decongestant do affect sleep and put more stress on the heart. This brings about fatigue and irritability and affects the work performance and children’s behavior patterns. 
According to Dr. Michael Silverman, assistant professor of psychiatry at Mount Sinai School of Medicine in New York, people shouldn't blame their allergies for deeper emotional issues. Allergies only aggravate an already-existing situation.
