<span>Empirical studies are results of analysis of data based on actual observation or experiences in the field. When conducting an empirical study, quantitative and qualitative approaches are employed, including:</span>
<span>1. </span><span>Providing data</span>
<span>2. </span>Emphasizes features of a new condition
<span>3. </span>Describes the current status of existing condition
<span>4. </span>Highlight associations between variables, but cannot establish causality, and
<span>5. </span>Suggest hypotheses which can be tested in analytical studies
<span>Qualitative empirical studies provide deep contextual data to help us understand a situation, but it cannot be used to establish its prevalence or incidence. It cannot be generalized also to highlight the statistical relationship between variables. If the aim is to measure the relationship, the quantitative methods should be used. A cross-sectional survey with large sample size is needed to describe the who, what, and where of a situation. Still, it cannot answer the why question. In order to answer the question of "why", an analytical or experimental study is needed. Experimental error is an important consideration here considering lapses or inaccuracies in the qualitative and quantitative data. </span>

Maintenance of the circadian rhythm is important because it helps keep the body's functions running normally.
Alteration of the circadian rhythm to a significant degree may lead to mood disorders including mild depression and seasonal affective disorder.
Abrupt shifts in routine such as shift change or travel resulting in jet lag can alter the sleep cycle and also environmental factors such as decrease in number of daylight hours. This can negatively impact the secretion of melatonin which induces us to sleep which will lead to less sleep and thus irritability and mood swings.
