Hot season last long

The long hot season makes me tired these days. I can stand hot season rather than cold season, but it's too long. I took nap this afternoon and I felt better. After submitting a trial, I read a book. I think it's better to read where something cooler, such as a cafe or a library. I might be able to concentrate than reading in my room. But I should go out very early hour or I will be tired on the way to cafe because of strong sunshine.
