Both of them will receive routine care. In intervention group, inhalation of rose water will be used by patients , Randomization description: Simple random method by flipping a coin will be used to determine the test and control groups. Then, convenience sampling method will be used for sampling within groups. N/A Anxiety. Control group: For two nights, 40 ml of ordinary water will be placed in a disposable bowl on the bedside table and will remain beside the patient from 22:00 to 6 am. Intervention group: For two nights, 40 ml of rose water will be placed in a disposable bowl on the bedside table and will remain beside patient from 22:00 to 6 am. As the scent of the rose water will spread in the area and could have an effect on the outcome of the study in the control group, two groups cannot be selected at the same time. Therefore, flipping a coin will be used to determine which group will be started first. Based on the coin, whichever group wins will be the first to start. After the research is conducted on the initial group which won the coin, sampling will be done for the next group. But, if the first group was the intervention group, sampling of control group will be started after three days. This three day period would ensure complete removal of any traces of the rose water scent in the study environment..
