Anxiety
During hot flashes, a person may experience intense and sudden anxiety. This may be because hot flashes may happen unexpectedly and catch the victim off guard; a person may experience sudden fear, nausea, and other symptoms of anxiety. They may experience severe trembling, nervousness, breathing rapidly, and a lot of sweating. They may also experience a lot of trouble trying to concentrate on tasks. Although, experiencing frequent anxiety attacks or prolonged anxiety may be signs that a person may have an anxiety disorder. However, it is not uncommon to experience it during a hot flash too.
