Today I just learnt an interesting information that's also unbelievable fact to me. While sleeping you may lose your weight. Amazing info, isn't it ? But, it's true. Now, let to know the reasons behind it --
During sleep you may lose your weight through breathing (respiration) and sweating (perspiration). An estimation of loosing weight is 1.9 grams of weight per minute. So, if you sleep 8 hours per day then you may lose about 1 Kg of weight. Most of the weight you lose during your sleep is water weight which escapes your body system.
Actually, each time we evaporate we lose a little bit of water. It’s easy to examine it – breath on a cool piece of glass and you will see some moisture.
