I am actually facing some weakness issues since 2 or 3 days. I am a self-employed guy, my work timings are quite odd like 10 pm to 5 am. I wake up by 12 pm and then work from 2 pm - 8 pm (this includes working, meetings, get together with friends and coffee). I do not prefer eating outside, to be safe. My eating schedule for breakfast has bread with vegetables or 2 rotis or parathas cooked with olive oil. Then I go out and have black coffee in a coffee shop close to my office. Then I return by 8 pm and have dinner directly. At night, while working, I have cherries, berries or milk depending on my mood.
I think I am feeling a bit weak or sick due to hot weather in my place. Yesterday at 2 pm, I decided to go to work, but I returned back as it was really hot here around 45-degreeCelsius. At that time, I felt like my legs were shaking while driving, and I felt like not going to the workplace. So I came back and slept. After an hour, I felt like super active, but again, when I went out after just an hour, I became exhausted and again felt like not doing any work or talking to anyone. I checked for fever and had nothing. My question is, what is causing this? How to get away from this feeling? How to stay active so that I can work productively? Please note: I do not get time to exercise because of my work schedule.
