It&#x27;s really a question of WHY for the researchers. But for those in the field, the solution is simple and you don&#x27;t need to know the why, you just work around it (by nasal breathing!)<p>Here&#x27;s some more that are more about the sleep apnea side of things:<p><a href="https:&#x2F;&#x2F;www.ncbi.nlm.nih.gov&#x2F;pubmed&#x2F;12615622&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.ncbi.nlm.nih.gov&#x2F;pubmed&#x2F;12615622&#x2F;</a><p><a href="https:&#x2F;&#x2F;www.ncbi.nlm.nih.gov&#x2F;pubmed&#x2F;14523179&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.ncbi.nlm.nih.gov&#x2F;pubmed&#x2F;14523179&#x2F;</a><p><a href="https:&#x2F;&#x2F;www.ncbi.nlm.nih.gov&#x2F;pubmed&#x2F;15342852&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.ncbi.nlm.nih.gov&#x2F;pubmed&#x2F;15342852&#x2F;</a><p>Point being: before you think you (or your kid) is &quot;ADHD&quot;, see to it that they are breathing and sleeping properly. They&#x27;re just so tired they become irritably unstable and unfocused. Lack of sleep = kids are a mess
