Wondering why some days you're on fire, full of energy, while other times you can barely keep your eyes open at your desk? Well, that's the magic of your body's internal clocks. Unlocking your peak productivity isn't just about working harder; it's about working smarter, understanding the intricacies of your body's natural rhythms.
In a busy, fast-paced lifestyle, it's easy to ignore the subtle cues our bodies provide. Imagine being able to identify your most productive hours effortlessly, tapping into a reservoir of focus and energy that aligns perfectly with your body's internal clock. This blog will take you through Circadian and Ultradian Rhythms, unveiling the secrets of your body's internal timekeepers.
It's not just about knowing when you're awake or sleepy, it's about knowing the exact moments when your brain is raring to go, ready to tackle tasks with gusto. We'll dive into the science and uncover the secrets behind your body's natural peaks of productivity. Ever had that 'aha' moment when everything just clicks? That's what happens when your tasks align perfectly with your body's natural flow. We're going to show you how to catch those moments more often, making your workdays more than just bearable!
A traditional method for measuring efficiency at work is to monitor productivity. For generations, both organisations and individuals have benefited greatly from effective management of productivity. Managing productivity can be a critical part of success in all aspects of your work and personal life. From an organisational perspective, the productive employee is more engaged, produces work faster and delivers higher quality results, from a personal perspective, effective productivity management allows you to accomplish more in less time, reaching your goals faster. However, did you know that everyone has hours each day where they’re more productive? One key aspect of maximising your productivity is identifying your most productive hours, as everyone is different it’s important to identify your most productive hours of the day and capitalise on them. So, let’s explore how you can pinpoint your peak productivity times and make the most of them.
While your employer might expect you to be at your best during all hours of the day, this is often an unrealistic expectation, even when the employees themselves want to be at their best at all hours of the day, this desire might not align with your natural rhythms.
There is a deep body of research showing that managing sleep and understanding your Circadian Rhythm is a key factor in reaching your highest levels of focus, this is called the ‘two process model of sleep regulation’. In simple terms, the two processes are the homeostatic process and circadian rhythm. The homeostatic process reflects your body's need for sleep, building up gradually as you stay awake and dissipates as you sleep. Essentially, the longer you stay awake, the stronger the drive to sleep becomes, making it essential to get sufficient rest to reset this process and maintain focus.
The Circadian Rhythm influences our energy levels and cognitive abilities throughout the day. These rhythms can vary from person to person but understanding them is crucial for optimising productivity. This is an internal timer which tells you when you should be awake and when you should be sleeping, it affects the duration of your sleep and what your brain does at night.
This rhythm affects your waking behaviour, you have peaks and troughs in energy throughout the day, affecting your ability to focus and affecting fundamental cognitive functions such as attention, ability to learn, and working memory, which are pillars of productivity. This rhythm works like a daily energy cycle, bringing waves of peaks and dips. Typically, we have waves of energy in the late mornings and afternoons, with a dip in energy generally occurring in the early afternoon, where you may feel relaxed or tired.
A generalised timeline of the Circadian Rhythm would go something like this, however, keep in mind that everyone is different, and this timeline might not fit your exact schedule, and could be influenced by multiple different factors:
- Morning (Approximately 6:00 AM - 9:00 AM): This is when most people naturally wake up. Cortisol levels in the body tend to be at their highest during this time, helping you feel alert and awake.
- Late Morning to Early Afternoon (Approximately 9:00 AM - 2:00 PM):This is the period of increased alertness and cognitive functioning. It's often considered the best time for activities that require focus and productivity.
- Afternoon (Approximately 2:00 PM - 5:00 PM): Alertness and cognitive function may start to decline in the afternoon. Often referred to as the "afternoon slump" it's a good time for a short break or a light snack to boost energy.
- Early Evening (Approximately 5:00 PM - 7:00 PM): Body temperature begins to decrease, and melatonin production (a hormone that promotes sleep)remains low. This period can be a good time for physical activity.
- Evening (Approximately 7:00 PM - 10:00 PM): Melatonin levels start to rise, signaling to the body that it's time to wind down and prepare for sleep. It's generally a good practice to avoid heavy meals, caffeine, and bright screens during this time to improve sleep quality.
- Late Evening (Approximately 10:00 PM - 12:00 AM):This is the ideal time to go to bed for most adults. The body continues to produce melatonin, and sleep onset becomes easier.
- Night (Approximately 12:00 AM - 6:00AM): Deep sleep typically occurs during the earlier part of the night, where REM sleep occurs more frequently in the latter part of the night.
By managing your sleep and harmonising it with your circadian rhythm, you can leverage this two-process model to attain your highest levels of focus and productivity. This means ensuring you get the recommended amount of sleep, improving sleep quality, and scheduling important tasks during your periods of heightened alertness.
Personally, I find my rhythm falling into a more generalised timeline. Waking up at 7, I feel most alert and productive from 8am to 11am, then again from 1:30 to 5after getting that lunchtime boost! However, in the past I have had completely different rhythms, waking up at 9 or 10 and feeing heightened alertness from 12pmto 5pm, which goes to show that over time with the right strategies and consistency, you can gradually shift your sleep/wake cycle to better align with your desired schedule.
The Ultradian Rhythm is another internal clocklike the circadian rhythm, but unlike the Circadian Rhythm which runs once over a 24-hour period, the Ultradian Rhythm is defined as being longer than an hour, but shorter than a day. Understanding this rhythm can help you schedule tasks and activities to make the most of your productive periods.
Ultradian Rhythms generally run on 90-minute cycles, though they are not strictly bound to 90-minute cycles for everyone, on average, over 90 minutes you will experience peaks and dips in energy, so finding out what schedule your Ultradian Rhythm runs on is a great way to maximise productivity. While some individuals may find success working in shorter intervals, others might prefer longer work periods, in any case high-energy work followed by periods of lower energy or fatigue is a good rule when trying to optimise your ultradian rhythm. During each work cycle, you can engage in intense, focused work, and then take a short break, approximately 20 minutes to recharge.
Over the duration of this cycle, research suggests that attention span and cognitive performance tend to peak during the first part of an ultradian cycle. This is when you're most alert, creative, and able to concentrate deeply. As the cycle progresses, your attention and productivity may start to decline.
Ultradian rhythms and circadian rhythms are separate clocks that run independently throughout the day running on different timelines, which means that for many people, there are specific times of day when ultradian peaks align with circadian peaks, resulting in super-productive periods. These are excellent times for tasks that require intense focus, problem-solving, or creative thinking.
Productivity is vital, and managing productivity effectively leads to a higher quality of work and better results. Identifying your most productive hours is a key part of maximising productivity, and the best way to go about this is aligning your daily goals with your natural rhythms. Circadian Rhythms, governing energy levels and cognitive abilities throughout the day, play a crucial role.
Recognising your personal Circadian Rhythm helps you schedule tasks during your most productive times. Understanding Ultradian Rhythms, which operate on average in90-minute cycles, allows you to harness peaks in productivity and recharge during breaks. The 90-minute work cycle is an effective method for utilising this rhythm, and if your lucky enough, and in tune enough with your body, aligning the peaks.
