If you are sweating every night, there is a good chance that it is related to your body temperature. During the night or at work, you do not have enough time for your body to cool itself down with sweat release. So if you are sleeping in an area where no air con unit can operate, then this will make you feel very uncomfortable. Fortunately, most of us don’t sleep like this anymore and instead choose to use cooling sheets during the night which help our bodies maintain normal temperature. However if it continues beyond 2-3 months of constant occurrence then see a doctor as soon as possible!
