Newborn sleep can feel unpredictable, with frequent wakings and irregular patterns. That’s because babies are not born with a fully developed circadian rhythm—the internal clock that regulates sleep and wake cycles. Instead, their sleep-wake cycle gradually matures over the first few months of life. Understanding how circadian rhythms develop can help parents set realistic expectations and create an environment that supports better sleep.
Your circadian rhythm, often referred to as your body’s internal clock, plays a crucial role in regulating sleep, wakefulness, and various physiological processes. When this rhythm is disrupted, it can lead to sleep disorders, fatigue, and even long-term health issues. Whether you’re dealing with jet lag, shift work, or poor sleep habits, restoring your circadian rhythm is possible with intentional changes. Here’s how you can reset your body clock and reclaim better sleep and health.
Circadian rhythms, often referred to as our "biological clock," are the natural, internal processes that regulate our sleep-wake cycle and repeat roughly every 24 hours. These rhythms influence various bodily functions, from hormone production to body temperature and eating habits. When these rhythms are disrupted or dysregulated, it can lead to a host of physical, mental, and emotional issues. In this blog post, we'll explore what circadian rhythm dysregulation is, its causes, effects, and how to get your rhythm back on track.
In the hustle and bustle of modern life, waking up early can be a challenging feat. However, there's a natural and powerful ally that can make this task a bit easier—morning sunlight. In this blog post, we'll explore the science behind the importance of getting sunlight first thing in the morning and how it can positively impact your wakefulness and overall well-being.
In a world that often glorifies early risers and productivity in the early hours of the day, there exists a group of individuals who dance to the beat of a different circadian rhythm. Delayed Sleep Phase Syndrome (DSPS) is a sleep disorder that disrupts the conventional sleep-wake cycle, challenging the societal norms surrounding sleep. Let's delve into the intricacies of this fascinating condition and explore ways to navigate its challenges.
Our bodies operate on a natural internal clock, also known as the circadian rhythm, which regulates essential functions such as sleep-wake cycles, hormone production, and metabolism. Keeping this internal clock in sync is crucial for overall health and well-being. In this blog post, we'll explore a series of strategies to help you maintain a healthy body clock and optimize your daily rhythms.
Have you ever noticed that there are certain parts of the day where you are feeling extremely alert, and then there are other parts of the day where you can barely keep your eyes open? This is because of two body systems: sleep/wake homeostasis and your circadian rhythm. The circadian rhythm serves as your internal body clock and tells your body when it is night and day. These two systems can control your sleep drive, or your body's need to sleep at any given time. Continue reading to learn more about your sleep drive and how it interacts with your body clock so that way you know how to better manage your sleepiness.
Modern sleep culture encourages going to sleep, and sleeping throughout the night. This is known as monophasic sleep because there is one time to sleep.
Some cultures practice biphasic sleep. This consists of sleeping throughout the night with a daily nap in the afternoon. In those countries, there are two times to sleep.
Polyphasic sleep schedules involve more than two sleeping periods each day. Quick nap breaks could count, with reduced sleeping throughout the night. Babies are examples of populations who follow a polyphasic sleep schedule. They follow this pattern until they are about three months old, and then they learn to sleep throughout the night with about two naps throughout the day. Others who work unusual hours or jobs that require attention at all times but also follow this sleep pattern.
There are some benefits and harms of polyphasic sleeping. Some prefer it, while others do not. Is it right for you? Continue reading to find out.
As we age, our circadian rhythm changes which can impact what time we need to go to sleep. The older we get, the earlier we are supposed to go to bed for an earlier wake time. This is due to many factors including changing eyesight (which can make us less sensitive to changes in light during the day), changing levels of melatonin, and other brain functions or hormone changes.
Research has supported the link between sleeping and health issues, including cardiovascular health disease. A recent study looked at bedtime and risk for myocardial infarction, or heart attack. Continue reading to find out more about this relationship and the relationship between sleep and heart health in general.
Your circadian rhythm is your innate biological clock that helps your body function in patterns and rhythms. It regulates your natural sleep schedule, and is closely tied to both melatonin, the sleep hormone, and changes in light.
Your biological sleep clock exists in a part of your brain called the suprachiasmatic nucleus of the hypothalamus, which sits right behind the nerves of your eyes – hence why your clock is sensitive to light.
It is crucial for you to understand your circadian rhythm in order to build healthy sleeping habits.
