Medication such as antihistamines and Montelukast are generally considered safe so you should continue to use these. To the best of our knowledge, there is no reason to think that antihistamines would lower the immune response.
Does exercise lower histamine levels?
Both tryptase and histamine concentrations increased during exercise, supporting the idea that mast cells are an important source of histamine responses to exercise in humans. The stimulus for the release or synthesis of histamine by specific cells in skeletal muscle in response to dynamic exercise is still unknown.
Can stress increase histamine levels?
When you’re all stressed out, your body releases hormones and other chemicals, including histamine, the powerful chemical that leads to allergy symptoms. While stress doesn’t actually cause allergies, it can make an allergic reaction worse by increasing the histamine in your bloodstream.
