Anyone who regularly suffers from sweats, hot flashes or night sweats wants to know the cause.
There are various reasons.
It begins in the chest area and spreads in waves over the neck and face to the scalp, often into the upper arms - the internal heat, accompanied by sometimes intense sweating, is something women in particular are familiar with.
Women experience these hot flashes particularly often as a result of hormonal changes, years before the last bleeding stops, starting around the age of 40.
Men can also struggle with this during their so-called andropause with the drop in testosterone levels.
Hot flashes can not only indicate menopause, but can also be related to illnesses, medications and eating habits.
What happens during a hot flash?
The disruption of thermoregulation in the body is often due to changes in hormone levels, as

This leads to a widening of the blood vessels, increased blood circulation, noticeable heart palpitations, dizziness, an increase in pressure, especially in the head, and associated sweating.

Hot flashes are one of the well-known side effects of menopause in women and men, but hot flashes with sweats, even at night, can also be an indication or a symptom of an illness.
Anyone taking certain medications can experience hot flashes as a side effect or interaction.
A sudden onset of internal heat with sweats, especially cold sweats, can also be due to reduced cardiac output - a heart attack is often heralded by sudden sweating.
But ultimately, certain eating habits can also influence the body's thermoregulation.
