Are Allergies Causing your Anxiety and Depression?

It is generally easy to see how stress can cause our hormonal systems to become imbalanced and cause all sorts of problems. Weight gain, sleeplessness, fatigue, and lowered immunity are common among people who are “stressed out”. But did you know that people with higher stress levels almost always have allergies as well? Allergies are our immune system’s overreaction to an allergen, commonly causing itching, hives, runny or dry nose, watery or red eyes, fatigue and headache. This immune system malfunction is sometimes brought on by stress.

Current studies have shown that there are direct links between histamines, the irritants produced in an allergic reaction, and the nervous system. Histamines are chemicals that are used by the brain to transmit signals between neurons. It is only when our immune systems overreact that histamines are released in copious amounts, causing problems.

People with too much histamine in their brains experience anxiety and depression. Increased levels of histamines in the brain are also responsible for stimulating the “fight or flight” response in the hypothalamic-pituitary-adrenal axis. When it is overstimulated, it causes anxiety, which results in depression. High histamine levels are directly connected to neurological disorders, like attention deficit disorder, anxiety disorder, obsessive compulsive disorder, and possibly Autism Spectrum Disorder and sensory processing disorder. Children with asthma have been found to have much higher rates of anxiety, depression, insomnia, and fearfulness than other children. This is thought to be a result of heightened histamine levels in the brain.

Antihistamine drugs are effective in blocking histamine receptors and some reduce the amount of histamine produced. However, the side effects of these drugs can be fatigue, sleepiness, or in some people, excitability, so a lot of the symptoms that should get better when histamines are reduced or blocked, don’t seem to go away. This is because, if you remember, our brains do need some histamines to transmit signals. So, by taking an antihistamine, you are risking so many signals being blocked that you experience brain fog and fatigue.

Vitamin C supplementation may be the answer for you if you are suffering from depression, anxiety, allergies, asthma, imbalanced immune system, or other neurological disorders. Vitamin C side effects are almost nonexistent. Vitamin C breaks down the actual histamine molecule, so it does not cause the side effects that medications do. This essentially balances histamine production and response so that the fight or flight response is not stimulated. This classifies vitamin C as a neuromodulator, meaning that it plays an important role in mental health. It can greatly reduce anxiety and has an antidepressant effect as well. It increases secretion of the hormone oxytocin, which is the “feel good” hormone of the brain. When there is not a sufficient amount of vitamin C in the body, behavioral abnormalities and fatigue are consistently seen.

Speak with your doctor about supplementing with vitamin C, like sodium ascorbate, a highly absorbable form of vitamin C.
