Histamines & the immune system

Histamines are natural compounds produced by the immune system that play a vital role in allergic reactions, digestion, and the regulation of the nervous system. When released, histamines trigger inflammation, increase blood flow, and cause symptoms such as itching, sneezing, congestion, headaches, or hives. While histamine is essential for protecting the body from allergens and infections, excessive levels can lead to histamine intolerance, chronic inflammation, digestive issues, and skin problems. Understanding histamines, their functions, common triggers (such as certain foods, alcohol, or stress), and ways to balance them through diet, lifestyle, or antihistamines is key to maintaining overall health and reducing unwanted symptoms.
