Study population: Nurses and doctors oncall working on acute medical and surgical admissions wards at the Queens Medical Centre Nottingham

Brief summary: The main purpose of this study is to assess and compare the hydration status of medical and nursing staff and to investigate the relationship between the hydration status, cognitive function and serum cortisol (marker of stress).

We hypothesise that a significant proportion of doctors and nurses will be dehydrated at the end of their working day. Some, as in other occupations, may be dehydrated at the start of their working day. This is likely to be associated with impairment in cognitive performance at the end of the working day compared to the beginning and expected to be more pronounced after a night shift. There may be less noticeable difference amongst nursing staff given the protected break time. Dehydration and associated impairment in cognition is of important clinical value as it can impact patient care. participants will be involved in the study for two shifts (one day and one night), aiming at 15 medical and 15 surgical nurses as well as 15 medical (total 15 day and 15 night shifts from each group) and surgical doctors (total 15 day and 15 night shifts from each group). Those that do not work both day and night shifts will participate for only one shift and a new participant will be recruited until target number of shifts is achieved.

Detailed description: End points

1. To assess the hydration status of hospital staff nurses and doctors oncall at work by measuring the following:

   1. Urine and serum osmolality
   2. Urine mass produced during the shift
   3. Kidney function (U \&Es)
   4. Bioimpedance measures

      2- To assess the effect of hydration on status of cognitive function and subjective feelings.

      3- To assess the association between hydration status on stress hormone (cortisol) levels.
