Good Morning. I'm a 22 year old male who us currently doing his internship. I was all fine for two months but since the past two days I've suddenly started feeling dizzy. By dizzy i mean when I move my head around I feel unstable. What is the reason for this and what needs to be done. Is it due to screen time as I've been on the laptop since day 1 of my internship or is it the heat cause it is extremely hot and I directly enter a cold environment where the AC is on blast. Kindly let me know as this is hampering my performance and making me feel sluggish.
