5. Belch

We know they are too irritating but no one should avoid these, they are an essential body function. You belch when your body needs to give away a little gas out of the body. Otherwise it also happens when you might have swallowed too much air which eating, chewing gum and from the carbonated drinks. However, it can also be a stomach infection.

6. Jerk In Sleep

Known as a Hypnic jerk, this generally happens when your body relaxes, which slows down your breathe and this makes your brain believe that you might be falling and hence that jerk to make you realize that ‘Oh boy, you might fall on the floor, so be conscious for that half of the second  please.’


Oh, ewww is the impression that you would give I know! But farts are good and are healthy. Farts are the results of undigested food in the stomach and intestine. After having traveled from small intestine, when the this undigested food goes to the large intestine, bacteria starts feeding on it and that creates gases – it has to be released out of the body. Everyone Farts, everyone!

8. Salivate

Our mouth produces saliva for a number of reasons like to lubricate the mouth, for breaking down the food or to act as a protective shield before we throw out. It helps the enzymes in your mouth to start the first step of digesting the food and that’s why when you see a tempting food, your mouth releases saliva that it is ready for the next meal.
