These few weeks, I really didn't sleep well. Felt so hot during the night, hence I had to turn on the fan. Yeah, you heard me. You can call me crazy for doing such thing during autumn right now but I felt extremely uncomfortable when I was sleeping. I get this kind of notion when I play football in the evening. Nevertheless, I'm not sure why I couldn't get a good night rest even when I didn't do any physical trainings during the day...hurm... Advice please? Anyone?
