Personally, I can't sleep sleep with my cloth on because I won't feel very comfortable especially during the hot weather. Utterly, sleeping with cloth on usually makes me feel irritated to the extend that my bod starts hitching me a lot. Though, during harmattan, I usually sleep with cloth because, just as my system detest heat same way it detest cold. My system react muchly to cold to the extend that I won't breath well, if I get exposed to much cold.
Heat is not favourable to human health, once I allow it for long I do notice my stomach gets swollen. So, apart from not wearing cloths while sleeping, I usually wash my self well before going to bed to enhance or allow free air. Furthermore, there are other conditions that I can comfortably put on cloth while sleeping which involves the use of AC. AC could make the room unbearable for me so I wear cloth and also use blanket.
