Some cities are never sleeps. Live rhythm has already run in 24 hours in some cities. For some of us, those kinds of live are not healthy.

 Crowded environment is not really healthy for us. It’s not for the body, but it’s for the mind and however, it may have some chances to impact the body. Imagine, if we live in such crowd neighborhood that full of noise.

 How do we suppose to get some rests inside that kind of neighborhood? That will be something that may impacts our body’s health as soon as it has done with our mind. Moving to the more quite place will be a wise option.

 Some of us may have to deal with some noise every day. Living and working in some kinds of noisy environments will have some kinds of impacts. If the noise happens all the time, the first organs that will feel the impact are ears.

That is why, some soldiers need to use ear cover (that is not headphones!) to cover their ear from the gun fire sounds. That will reduce the impacts of the gun fire sound.

 Some workers are some kinds of manufacturing companies will also need to use the ear cover. The constant sounds of the manufacturing machines might have some negative impacts for their ears.
