An early stage of hyperthermia can be "heat exhaustion" (or "heat prostration" or "heat stress"), whose symptoms can include heavy sweating, rapid breathing and a fast, weak pulse. If the condition progresses to heat stroke, then hot, dry skin is typical [2] as blood vessels dilate in an attempt to increase
Several key mistakes could throw off the accuracy of blood pressure readings for people who take them at home. The average "normal" blood pressure is 120/80, according to the American Heart ...
Elevation and decrease of blood pressure reading usually occurs without intervention. However, if the normal resting pressure remains abnormally excessive, common signs and symptoms that are present include: Headache , Heart palpitations , Flushing , Tinnitus (ringing or buzzing noise in one or both ears), Weakness of body, Dizziness and ...
Heat syncope is fainting or dizziness as a result of overheating (syncope is the medical term for fainting). It is a type of heat illness. The basic symptom of heat syncope is fainting, with or without mental confusion. [1] Heat syncope is caused by peripheral vessel dilation, resulting in diminished blood flow to the brain and dehydration.
However, experts say it's possible to use electric space heaters safely. If your model is new, is in good working condition, has safety features like automatic shut-off in case of overheating or ...
Blood pressure is recorded as two readings: a higher systolic pressure, which occurs during the maximal contraction of the heart, and the lower diastolic or resting pressure. [11] In adults, a normal blood pressure is 120/80, with 120 being the systolic and 80 being the diastolic reading. [12] Usually, the blood pressure is read from the left ...
For example, if a person’s actual blood pressure is 134, and blood pressure is measured on a dangling arm, the reading could end up over 140, which is considered to be stage 2 hypertension.
When overheating, the temperature of the part rises above the operating temperature. Overheating can take place: if heat is produced in more than expected amount (such as in cases of short-circuits, or applying more voltage than rated), or; if heat dissipation is poor, so that normally produced waste heat does not drain away properly.
