Explanation:
Fainting is known as lipotimias, syncopes or presyncopes, when knowledge is not lost. They occur when not enough blood reaches the brain in a situation of transient hypotension, in which the regulatory mechanisms that redistribute blood to the brain to maintain oxygen fail. "It is the lack of cerebral percussion that causes the loss of consciousness producing hypotension that lasts a few seconds or minutes," as the expert points out.
Syncopes are generally benign, except for those with a cardiac cause, which are more violent syncopes of sudden death, in which the patient does not have time to react and loses consciousness completely.
The rest are the vasovagal or neuromediated syncopes, which represent a problem when the patient suffers them very frequently or if he falls and is hurting himself. The symptoms that are usually experienced when suffering from syncope can be: feeling of emptiness in the stomach and heat in the head, dizziness or instability and cold sweating.

A location's weather could be scattered or generally misinterpreted as weather can be random at times.
