Figure 1: An illustration of the sleep pattern changes, working hours, and light exposure during standard time, daylight saving time, and Ramadan month in countries that delay the starting time of schools and work during Ramadan. Assuming a sleep period from 11 PM to 6 AM, and a work/school period that starts at 7/8 AM during the standard time. There is a shift delay in bedtime and wake time during Ramadan, which decreases light exposure in the morning and increases light exposure duration in the evening
