Under conditions of moderate alcohol consumption where blood alcohol levels average 0.06–0.08 percent and decrease 0.01–0.02 percent per hour, an alcohol clearance rate of 4–5 hours would coincide with disruptions in sleep maintenance in the second half of an 8-hour sleep episode.
Low blood pressure and a fast heart rate after the event may indicate blood loss or dehydration, while low blood oxygen levels may be seen following the event in those with pulmonary embolism. [1] Routine broad panel laboratory testing detects abnormalities in <2–3% of results and is therefore not recommended. [20]
Micturition syncope or post-micturition syncope is the name given to the human phenomenon of fainting shortly after or during urination. The underlying cause is not fully understood, but it may be a result of vasovagal response , postural hypotension , or a combination thereof.
This condition occurs within five days of acclimatization to higher temperatures, before the blood volume expands. [3] The result is less blood to the brain, causing light-headedness and fainting when a person stands up quickly or stands for a long period of time.

In heat syncope, or exercise-associated collapse, there is an increased dilation of blood vessels near the skin's surface and a pooling of blood in the lower extremities due to a decrease in vasomotor tone, which is the extent of control over the constriction and dilation of blood vessels. This results in a drop in blood pressure when not lying ...
