But due to todays weather outside, excessive himidity is there inside the house, she feels sweating and a have sometime dizzy feeling, then she comes under the fan or the cool area she feels fine. But this episode of sweating and dizzy is there. After having some liquid/energy drink she feels ok. But again occurs. This thing never happened to her. This is the first time. No any other symptoms are seen eccept these issues. This all started from today morning. From morning 6.00 a.m here thr temeprature was around 30° and humidity was on higher side. Is this signs are cause for concern or due to some normal happening issue. Please guide me.
