Circadian Sleep Disorder
A circadian sleep disorder occurs when your internal body clock is out of sync with the sleep schedule required by work, school, family life, or other daily activities. The result is often not an inability to sleep in general, but difficulty sleeping at the expected time. Someone may feel alert late at night, become sleepy […]
How Much Sleep Does A 5 Month Old Need
At five months, many babies are beginning to develop a more predictable difference between day and night. Nighttime sleep may become more consolidated, while naps gradually settle into a clearer pattern. Even so, sleep needs vary considerably from one baby to another. Understanding developing circadian rhythms can clarify why a five-month-old’s sleep patterns and daytime […]
5 Month Old Wakes Up Every 2 Hours
Frequent waking is common around five months, but that does not make it easy for tired parents. Some babies wake every two hours overnight, while others wake more often during naps or need help returning to sleep after each brief awakening. Understanding circadian sleep patterns can explain why a five-month-old wakes frequently and how sleep […]
Explain Circadian Rhythms
Circadian rhythms are repeating changes in the body that follow an approximately 24-hour cycle. They help coordinate when you feel alert or sleepy and influence many other functions, including mood, appetite, hormone activity, digestion, and daily energy levels. For a deeper look at sleep cycle timing, explore how biological clocks shape nightly rest. Your circadian […]
Internal Clock
Your internal clock helps organise the body’s daily pattern of sleep, alertness, hormone activity, temperature, and metabolism. This timing system is commonly called the circadian rhythm. The word refers to a cycle that lasts “about a day”: close to 24 hours, although the precise timing can vary from person to person. Understanding your internal clock […]
Circadian Rhythm & Sleep Cycles
Sleep is influenced by two connected systems: the body’s internal clock, which helps determine when you feel awake or sleepy, and the repeating stages of sleep, which shape what happens after you fall asleep. Understanding both can make it easier to identify why sleep feels restorative on some nights and disrupted on others. What is […]
