Sleep and rest

Sleep and rest is about the hours that hold the rest of the day up, in cities that stay warm and awake late. In the UAE and Saudi Arabia, long working days, late dinners, early school runs and summer nights that barely cool can all push bedtime later while the alarm stays where it is. These articles explain how much sleep adults and children need according to health authorities, what happens across the stages of a night, why a hot bedroom makes sleep harder, and how light, screens, caffeine and meal times fit in. They also cover naps, shift work, travel across time zones and the change that Ramadan brings to the night. Each page defines its terms the first time they appear, cites its sources with the date they were checked, and keeps to what the research shows. Practical steps are offered as options to consider, not rules to follow. This is general information, not medical advice. Loud snoring with pauses in breathing, or tiredness that does not lift after rest, is worth raising with a doctor. Sisly reads sleep against your own normal, not against anyone else's night, and it does not coach. It is not a medical device.
