Circadian rhythm weekend recovery -
It is possible to change your circadian rhythm through a few different mechanisms, like consistently changing your bedtime and wake time, exposure to sunlight, relaxation exercises, and temperature changes. When your bedtime and wake-up time is consistently later than average, then your circadian rhythm is shifted to later hours.
In other words, instead of becoming tired at 10pm, a person with late sleep patterns might not become tired until 1 in the morning. Perhaps you have a goal to wake later or fall asleep earlier, then you can take steps to shift your circadian rhythm to meet this goal, which we outline below.
It can be difficult to adjust sleep schedules because the circadian rhythm affects tiredness levels. If you are naturally tired in the early morning hours and fall asleep at 2am, it will be frustrating and likely futile to try to sleep at 10pm. Instead, try moving your bedtime back by minutes gradually.
As your circadian rhythm adjusts to your new bedtime and wake-time, you will find yourself becoming sleepy at the time you desire. Similarly, slowly adjusting your wake time can be more effective than a sudden shift.
When wake times and bedtimes are consistent, your circadian rhythm will help you fall asleep and wake up more easily, as you will feel tired before bed and alert as you wake up. Your body has two main processes that dictate your alertness, how long you have been awake, called your homeostatic sleep drive , which is largely impacted by deep sleep, and the hour circadian rhythm.
These two processes, combine to form the two process model of sleep and a typical energy level like what is articulated in the above graph.
Notice how there are peaks and valleys and the overall reduction in alertness until bedtime. If you are a morning lark, this rhythm will be shifted earlier in the day, whereas if you are a night owl it will be shifted later. Circadian components are affected by sleep schedules, but they are also affected by your environment, particularly, exposure to sunlight , but also when you eat, exercise, and even when you socialize.
When your body is exposed to sunshine, it causes a chemical reaction through photoreceptors in your eyes that send a signal to your suprachiasmatic nucleus that makes your body feel more alert.
By opening your blinds and turning on the lights as soon as you wake up, you will shake off morning grogginess more quickly than if you leave the blinds closed. Another hack if you want to counteract morning grogginess - try splashing some cold water on your face to start revving up your core body temperature.
The other side of light exposure is that it often takes longer to fall asleep if you have just been exposed to bright light close to bedtime especially blue light. By adjusting light exposure, you can help your body to feel alert or sleepy, depending on if you want to wake up or fall asleep.
Getting blackout blinds is one of the best solutions to start controlling your light exposure. Also limit sunglass usage during the day to ensure you get the light you need to set your rhythm.
However, getting direct sun exposure, not through a window, but directly outside is probably the best way to entrench a healthier circadian rhythm.
This will also help you fall asleep, stay asleep, and get a deeper night. Napping during the day can help to alleviate the mid-day sleepiness that comes with the circadian rhythm. Short naps of minutes during periods of tiredness can help keep you focused and alert throughout the day.
Alternatively, drinking caffeine can also help you counteract that afternoon dip. For the best effect with caffeine in terms of addressing that afternoon dip, try not to drink it right in the morning, but around minutes after you wake up.
Then try to stop drinking caffeine at around 2 pm - 3 pm based on a typical sleep schedule of waking up between am. Also, some people just don't like taking naps, and that can be perfectly healthy as well.
There are a few different styles of sleeping that can lead to a healthy circadian rhythm, many of which are impacted by societal pressures and responsibilities. By tracking your own periods of peak alertness and sleepiness, you can ascertain your own personal circadian rhythm.
There are even genetic tests you can take that tell you if you have genes that make you more likely to be a morning lark, night owl, or as we call it, a flexible octopus. Take our sleep quiz to discover your sleep animal.
Knowing your unique energy rhythm means that you can better schedule your daily activities. If you always feel tired at 4pm, then you can schedule a run or a nap before this period to help reduce your feelings of tiredness. If you are at your most alert at 10am, then scheduling important meetings at this time can ensure that you will be alert and at you best.
Generally, most people find that it is better to do analytical work in the morning and more creative work in the late afternoon or night. Your unique chronobiology is influenced by your genetic makeup and environmental cues called zeitgebers.
Everyone can shift their circadian rhythm to some degree with these zeitgebers. The evolutionary basis for this relates to always ensuring that a member of the tribe is awake to protect the camp.
Unfortunately our modern society was forged out of industrialism in a way that is unjustly preferential towards early rises, with strict morning work times. For an in-depth understanding of chronobiology and sleep inertia check out an interview Dr.
Thankfully, we can impact the expression of our genes through our environment in order to create a healthier circadian rhythm. Zeitgebers are environmental cues like sunlight, exercise, and eating that impact your circadian rhythm and energy levels throughout the day.
Temperature and even social interactions can also create environmental cues that tell your body when to be alert. These external cues reset the internal body clock, also known as your circadian rhythm. Naturally occurring sunlight is the strongest zeitgeber because of its impact on hormones like melatonin.
Even when our eyes are closed, photoreceptors in the eye can detect sunlight. These photoreceptors respond to sunlight by inhibiting melatonin. Due to the fact that we have become indoor creatures, people are often out of touch with their circadian rhythm.
This happens when you do not entrench your zeitgebers within your daily schedule. A major cause of irregular sleep schedules is when people go out on the weekend, but wake up early for work on weekdays. If going out late at night is very important to you, here is a simple hack.
Make Friday night your late night so your body has more time to adjust to an earlier wakeup later in the weekend. Everyone should have an ideal bedtime and wake-time goal that you strive to be consistent with. This goal should take into account your sleep need, which is another essential factor for healthy sleep.
Typically, sleep need should be prioritized above consistency. You can simply use your iPhone or Android clock alarm to set a morning wake up time goal, or take it to the next level by downloading an app like SleepSpace. SleepSpace will continuously notify you to awaken until you open the app and uses sound and light to reduce morning brain fog.
In sleep science, this refers to external cues that can entrench your circadian rhythm. In other words, you can shift or strengthen your circadian rhythm when you align certain external cues with your goals.
The Zeitgeber that has the largest influence on your circadian rhythm is natural sunlight, but other factors include the timing of meals, exercise, and even when you socialize.
For example, if you want to shift to being more of a morning person, getting sunlight as early as possible can help with this process. Many people also engage in intermittent fasting nowadays. However, if you are trying to be a morning person and fast during the morning, this sends the wrong cue for healthy circadian alignment.
Morning people will often be better off expending and consuming energy in the morning. Whereas, evening people will be better off doing so in the evening. If you sleep from 1 a. on weekends, the midpoint shifts two hours later to 5 a. Higher levels of social jetlag are associated with higher rates of obesity, inflammation, smoking, and alcohol use.
The worse your social jetlag, the higher your likelihood of depression. For example, social jetlag of two hours, as opposed to one hour or less, is associated with higher levels of cortisol a stress hormone , shorter weekday sleep, less physical activity, and a higher heart rate.
These conditions increase your risk of developing diabetes and depression. However, even just one hour of social jetlag can have serious effects. When your sleep schedule varies from weekdays to weekends, it disrupts your circadian rhythm. Your circadian rhythm is best known for managing your sleep-wake cycle, but it also helps regulate a whole host of biological functions, from your energy and body temperature to your appetite and metabolism.
Accordingly, people who get insufficient sleep on a regular basis are more likely to experience weight gain, metabolic dysfunction, and obesity-related diseases like diabetes and inflammation.
Short sleepers may gain weight because they can be more likely to engage in late-night snacking after dinner. When they get extra sleep on weekends, studies show that it reduces their late-night cravings on those nights. However, once these sleepers return to the sleep deprivation of a typical work week, their snacking resumes.
Their insulin sensitivity also decreases, which is a warning sign for diabetes. Effectively, the benefits of the weekend sleep are canceled out by the following workweek. You may need several nights of good sleep to fully recover.
Going to bed a little earlier on weekends can help you recoup sleep debt without sleeping in too late and throwing off your circadian rhythm. The best test is to pay attention to how you feel when you sleep in on weekends. Do you feel awake and alert, or do you feel groggy and grumpy?
A better approach to catch up on sleep debt may be with a nice, refreshing nap. Let yourself relax with a short to minute nap on Saturday or Sunday afternoons, ideally between 2 p.
and 3 p. Keeping your naps short and sweet prevents you from feeling even groggier upon waking up. Are you exhausted from the week, or are you staying up later on weekend nights? What else changes about your schedule on the weekends?
For example, you may be drinking or eating more heavily, especially later at night. Heavy foods and alcohol can both interfere with the quality of your sleep, so you may want to sleep in later to make up for it. There is some evidence that sleeping in on weekends may recoup some sleep debt, but experts still recommend consistency as the best approach for healthy sleep.
Try these tips to get more sleep during the week. Sleeping in on the weekends can feel great, but it makes returning to early Monday mornings even tougher. See if the tips above help you get more sleep during the week, and you may not need to sleep in so late on the weekend.
