Brief Summary

This study will observe the participants fasting during the month ramadan. Descriptive characteristics and assessments of sleep, food consumption, body composition, cognitive skills, anticipation time, and physical activity will be conducted before, during and after ramadan.

Detailed Description

The aim of this is investigating the changes in sleep patterns, dietary intake, cognitive skills, anticipation time and physical activity levels during Ramadan in healthy young women.

After giving information about the research, participants' descriptive characteristics such as age, height, body weight, body fat percentage, and chronotype (Morningness-Eveningness Questionnaire) will be determined and recorded. Participants' sleep patterns (Actigraphy and Pittsburgh Sleep Quality Index), food consumption (BEBIS), cognitive skills (Stroop test, Letter digit test), anticipation time (Bassin Anticipation Timer), and physical activity levels (International Physical Activity Questionnaire) will be assessed before Ramadan (Pre-R), in the first week of Ramadan (FW-R), in the last week of Ramadan (LW-R) and after Ramadan (Post-R). Additionally, body composition measurements will be taken in Pre-R, LW-R and Post-R. The completion of questionnaires and scales will be conducted individually in a quiet environment. Sleep records will be obtained using an actigraphy device in the participants' own sleep environments. Other measurements will be conducted at the University Performance and Exercise Physiology Laboratory under controlled temperature (22-24°C) and humidity (50-60%).
