“This leads to more biofilm and plaque buildup, so rinsing with a neutral or basic water can help lower the pH in the mouth.” In an acidic environment or an environment below 4.5 pH , the ...

Hematidrosis is a condition in which capillary blood vessels that feed the sweat glands rupture, causing them to exude blood, occurring under conditions of extreme physical or emotional stress. [4] Severe mental anxiety activates the sympathetic nervous system to invoke the fight-or-flight response to such a degree as to cause hemorrhage of the ...
