Allergic rhinitis impairs sleep, potentially increasing the risk of mood disorders and suicide. Addressing sleep disturbances may offer new therapeutic targets for these conditions.
Area of Science:
- Immunology
- Psychiatry
- Sleep Medicine
Background:
- Allergic inflammation is linked to mood disorders, depression, and suicidal behavior.
- Inflammatory mediators, particularly Th2 cytokines from allergic inflammation, disrupt sleep patterns.
- Sleep impairment is a significant risk factor for suicide and is associated with mood disorders.
Purpose of the Study:
- To review the literature and propose a hypothesis linking allergic rhinitis to mood and anxiety disorders and increased suicide risk through sleep impairment.
- To explore the pathophysiological role of sleep disturbance as a link between allergic rhinitis and mental health outcomes.
Main Methods:
- Literature review of studies on allergic inflammation, sleep, mood disorders, and suicide.
- Analysis of mechanisms by which allergic rhinitis affects sleep (mechanical and molecular).
Main Results:
- Allergic rhinitis can impair sleep via obstructive and molecular (cytokine) pathways.
- Impaired sleep is a modifiable suicide risk factor strongly associated with mood disorders.
Conclusions:
- Sleep impairment presents a plausible pathophysiological link between allergic rhinitis and mood/anxiety disorders, including increased suicide risk.
- Further research into sleep disturbance as a therapeutic target for mood disorders is warranted given the high prevalence of allergy and mental health conditions.

Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
