Hyperventilation may come in many forms, with many of the diseases we face nowadays are related to our breathing. As humans, we now breathe faster and take bigger breaths than we used to. Chronic Hyperventilation lowers your carbon dioxide levels in the blood and causes inefficient oxygen delivery to your tissues. Lower CO2 levels results in smooth muscle contraction causing narrowing of blood vessels and of airways. This, in turn, causes poor circulation and breathing difficulties. This over-breathing results in the development of health conditions such as asthma and hay fever, chronic fatigue syndrome, anxiety and stress, snoring and sleep apnoea.
