Few things are as important to our overall health and well-being as getting a good night’s sleep. But did you know that our body clock and sleep cycles have a significant impact on the quality and quantity of our sleep? Understanding our internal rhythms can help us improve our sleep, mood, and energy levels, as well as our cognitive function.
A survey by Vitabiotics found 25% of adults in the UK are lacking in energy at the moment with many turning to coffee, exercise and power naps for an energy boost.
Our internal biological clock, also known as the circadian rhythm, regulates our sleep-wake cycle. This rhythm is influenced by environmental cues such as the amount of light we are exposed to and is regulated by the release of certain hormones. When our body clocks are in sync with our daily schedule, we can naturally fall asleep and wake up without the use of an alarm clock. Insomnia, fatigue, and other sleep-related issues can occur when our body clocks are out of sync.
We’ll take a deep dive into the world of body clocks and sleep cycles, and explore how we can use this knowledge to improve the quality of our sleep. We’ll cover everything you need to know to get your best night’s sleep yet, from understanding the factors that affect our body clocks to learning how to align them for optimal sleep.
What is our body clock?
Our body clock, or circadian rhythm, is our internal biological process that regulates the sleep-wake cycle, hormone production, and other physiological processes. It is influenced by factors like natural light, diet, and temperature, and can also be linked to our genetics.
How does my body clock affect sleep?
Our body clock is essential in regulating the sleep-wake cycle. It helps in determining when we are sleepy and when we are alert. We are more likely to fall asleep easily and wake up feeling refreshed when our body clocks are in sync. When our body clock is thrown off, we can experience insomnia, daytime drowsiness, and other sleep-related problems.
What can affect my body clock and sleep pattern?
Our body clocks are influenced by a number of internal and external factors, some of which we can control and others that we cannot. Genetics is one of the most important internal factors. Certain genetic variations have been shown in studies to affect our circadian rhythm, making us more or less susceptible to certain sleep disorders.
The Period (PER) gene is a key gene that has been linked to our body clocks. Variations in this gene can affect the timing of our internal rhythms and help to regulate the timing of our sleep-wake cycle. People with one variant of the PER gene, for example, are more likely to be “night owls” and have difficulty falling asleep at night, whereas people with another variant are more likely to be “morning people” and wake up earlier.
The Clock (CLOCK) gene is another important gene that affects our body clocks. This gene is involved in the regulation of our internal rhythms, including the production of melatonin. Variations in this gene can affect the timing of our sleep-wake cycle as well as our light sensitivity.
Can I change my body clock type to be more of a morning person or night owl?
There has been some research into this, and while some people may be naturally inclined to be morning people or night owls, our body clock is also influenced by environmental and lifestyle factors. By making changes to our sleep and wake schedule, exposure to light, and other lifestyle habits, it may be possible to shift our body clock to some extent. But remember, that it can sometimes be down to genetics and it’s all about finding a schedule that really works for you.
The amount of light we are exposed to, temperature, and noise level are all external factors that can influence our body clocks. Light is one of the most powerful cues that our bodies use to determine whether it is time to wake up or sleep. Natural light helps to set our body clocks during the day, whereas artificial light at night can disrupt them. Similarly, a room that is too hot or cold, or that has too much noise, can make it difficult to sleep.

Our lifestyle habits also have a significant impact on the regulation of our body clocks and sleep cycles. A diet high in sugar and caffeine, for example, can make it difficult to fall asleep, as can a sedentary lifestyle. Regular exercise and a healthy diet, on the other hand, can help to improve the quality of our sleep. Our work schedule is also important; people who work rotating shifts or have irregular schedules are more likely to have their body clocks and sleep cycles disrupted.
How can I reset my body clock?
There are several strategies that can help to reset the body clock, including:
- Establishing a consistent sleep schedule
- Exposing yourself to natural light during the day
- Avoiding screens before bed
- Winding down before bed
- Eating habits
- Avoiding jet lag
Can certain foods or supplements help to regulate the body clock?
There is some evidence to suggest that certain foods and supplements may help to regulate the body clock, including Melatonin supplements, omega-3 fatty acids, vitamin D and B12, and certain herbs such as valerian root and chamomile.
Get in sync with your body clock
Once we understand the factors that influence our body clocks and sleep cycles, we can learn how to align them for better sleep. Establishing a consistent sleep schedule is one of the most important things you can do. This includes going to bed and getting up at the same time every day, including weekends. This helps to regulate our body clocks and makes falling asleep and waking up naturally easier.
Exposure to natural light is another important factor in resetting our internal clocks. We should try to spend time outside in natural light during the day, whether it’s going for a walk or simply sitting near a window. This aids in the regulation of our body clocks and can improve the quality of our sleep. We should avoid artificial light at night, especially blue light emitted by screens, because it can suppress the production of melatonin, a hormone that helps us fall asleep.
How does artificial light affect the body clock?
Artificial light, especially blue light that’s emitted by our phones, laptops and other devices, can disrupt the body clock by suppressing our production of melatonin, a hormone that helps us to regulate our sleep-wake cycle. This can make it more difficult to fall asleep and can contribute to insomnia and fatigue.
In addition to these steps, it’s important to wind down before bed. This means creating a relaxing bedtime routine that helps to signal to our bodies that it’s time to sleep. Some techniques that can help include reading, listening to calming music, or practising meditation.
What are the best ways to synchronise my body clock?
Some of the best ways to synchronise your body clock include:
- Establishing a consistent sleep schedule
- Exposing yourself to natural light during the day
- Avoiding screens before bed
- Winding down before bed
- Eating habits
- Avoiding jet lag
By establishing a consistent sleep schedule, exposing ourselves to natural light during the day and avoiding screens before bed, and winding down before bed, we can train our body clocks to fall asleep and wake up at the right time and improve the quality of our sleep.
How poor sleep can affect your health
While synchronising our body clocks for optimal sleep can improve our overall health and well-being, disrupting our sleep cycles can have the opposite effect. Insomnia, fatigue, and other sleep-related issues can occur when our body clocks are out of sync. These disruptions can be caused by a variety of factors, including jet lag, shift work, or even a change in our daily routine.
Disrupted body clocks and sleep cycles can have significant consequences for our mental and physical health. Sleep deprivation can lead to irritability, mood swings, and difficulty concentrating. It can also increase the risk of chronic diseases like diabetes and heart disease.
How does my body clock affect my mental health?
Sleep interruptions and insomnia can have a significant impact on our mental health. Sleep is necessary for restoration, and lack of sleep can contribute to depression, anxiety, and other mental health issues. People who work night shifts may be more vulnerable to mental health issues, which is why employers must provide specific support that takes into account how their natural body clock is impacted by their shift pattern.
Jet lag is a common cause of disrupted body clocks and sleep cycles when we travel across multiple time zones. It can take several days for the body to adjust to the new time zone, resulting in fatigue, insomnia, and other symptoms. Similarly, shift work, which requires us to work outside of the typical 9-5 schedule, can disrupt our body clocks and sleep cycles.
How does jet lag affect my body clock?
Jet lag can cause symptoms such as insomnia, daytime drowsiness, and difficulty adjusting to the local time. To avoid jet lag, it’s best to gradually adjust your sleep schedule in the days leading up to a trip, and to avoid exposure to artificial light at night when travelling.
The good news is that we can take steps to manage and recover from these disruptions. For example, in the days leading up to a trip, it can be beneficial to gradually adjust our sleep schedule and to avoid exposure to artificial light at night when travelling. It can be beneficial for shift workers to take steps to align the body clock, such as establishing a consistent sleep schedule, exposing themselves to natural light during the day, and winding down before bed.
Wrapping up for a good night’s sleep
We’ve explored the world of body clocks and sleep cycles, and how understanding these internal rhythms can help us optimise our sleep, improve our mood and energy levels, and even boost our cognitive abilities.
By taking the time to understand and take care of our body clocks and sleep cycles, we can improve the quality of our sleep and overall health and well-being. Remember that this is an ongoing process and requires consistent effort, but the benefits are well worth it! We encourage you to make sleep a priority and take steps to align your body clock for better overall health and wellness.
