What is, then, the ideal number of students in a language classroom? How small is too small, how large is too large? Based on their experience, our participating language teachers suggested that the ideal class size is between 10-12 students. Locastro in her article Large Size Classes: The Situation in Japan (1989) reported the responses of students and instructors on the topic.
Due to estrogen levels decreasing, hormonal and biochemical imbalances occur, according to the 34 Menopause Symptoms website. The falling estrogen levels are thought to be the cause of both hot and cold flashes. The hypothalamus, the area of the brain responsible for body temperature regulation, becomes overactive. This causes the hypothalamus to release chemicals that cause blood vessels in the skin to expand in order for heat to be emitted.
Both estrogen and testosterone seem to protect against frequent hot flashes. If either of those hormones are withdrawn after one's body is used to them, a rapid increase in skin temperature due to dilatation of the skin blood vessels can occur very frequently.
