A hot flash is a brief feeling of intense warmth and sweating. Hot flashes commonly occur in women around the time of menopause. Researchers do not know exactly what causes hot flashes.

This drop affects the hypothalamus, an area of the brain that regulates body temperature.
Consider this: A newspaper ad is only good for a day and a television commercial only lasts about thirty seconds. But a billboard ad is working for you twenty-four hours a day, seven days a week. The cost of billboard advertising ranges from about $700 to $2,500 a month. At that rate, ten billboards could run as much as $25,000 per month. That sounds like a lot of money, until you realize that a full-page ad running for one day in a major newspaper costs about the same. Advances in technology have also contributed to billboard advertising's cost efficiency.
