What are body clocks?

Lark and owl, Early risers are called “larks,” and they are more active in the morning, whereas those who sleep longer and are busy until the wee hours of the morning are referred to as “owls.” Being a Lark or an Owl is a rewarding experience. You might be debating whether it is preferable to be a lark or an owl in this situation. Let us learn more about lark and owl:

What are body clocks?

What concerns us is that we are all prone to the effects of our internal clocks, regardless of whether we are nocturnal or nocturnal. Most believe that every cell in the body has a truly customized body clock, which regulates how alert or fatigued we feel over a 24-hour night. It is supported by research. Despite our most recent study, our body clock has a considerably more significant influence on us than previously believed.

Peak performance and the body clock:

Participants were asked to complete various cognitive and physical tasks to determine their capacity to react swiftly and plan. Exams were given three times a day. According to our data, the peak performance of larks and owls was significantly different.

Physical and mental exercise:

Larks outperformed night owls in neuropsychological activity by 7 per cent, and 8 per cent at 8 am and 2 pm, respectively. Both night owls were at their sharpest at 8 p.m. when their mental and physical faculties had peaked. At nightfall, owl grip strength was 3.7 per cent stronger than lark grip strength.

Wake-up mental exercises:

Also, the amount of time it takes you to achieve your optimal performance level after waking up has been connected. It was found that Larks were best at cognitive tests immediately after waking up and at physical tasks seven hours later. People who like to stay up late performed best on all functions within the first 12 hours of awakening.

Involvement of the brain’s suprachiasmatic nucleus:

Our circadian rhythms have a significant role in how well we can concentrate and work physically and mentally throughout the day. The suprachiasmatic core, which is responsible for detecting light, receives these signals from the cells in your eyes while it is dark outside. The hormone melatonin is released; as a result, making one tired.

Biological clock influences:

Another factor that impacts how your biological clocks influence your daily routines is your chronotype. – In the mornings, persons of early chronotypes have the most energy, but by lunch or early evening, they’re fatigued and need a break. Late chronotypes are tired in the morning but awake and attentive at night. Many other physiological, behavioural, and genetic rhythms may also demonstrate these individuals’ variances throughout a roughly 24-hour period.

Release of melatonin:

The release of melatonin, for example, is determined by chronotype. Melatonin levels peak at 6 p.m. for morning larks, making them sleepy by 9 or 10 p.m. Because melatonin levels might rise as late as 10 pm or 11 pm for night owls, many don’t fall asleep until 2 or 3 am. Genetics can play a role in determining your body clock type, but your schedule and lifestyle also play a significant role. It also evolves over your life.

How many years of life consider Lark?

The first ten years of life tend to be larks; later, adolescents and early twentysomethings become night owls.  By the time you’re 60, your sleeping patterns will be very similar to those you were ten. Despite these changes throughout your lifetime, the characteristics that form your chronotype are specific to you about lark and owl.

Peak athletic performance:

For professional athletes, winning margins can be razor-thin, so they always look for the tiniest advantages. For example, Usain Bolt was 0.25 seconds quicker than the final competitor in the men’s 100m fast at the 2016 Olympics. Being an early riser or an early sleeper is an essential factor in timing peak athletic performance for both individuals and teams.

Difference between lark and owl:

According to a recent study by our researchers, night owls are 8.4 per cent more sleepy in the morning than larks. They’re also 7.4% weaker than their dawn chorus counterparts using a maximum grip strength test. On the other hand, Larks show a minor variance in peak performance during the day than night owls. An early riser will be more impaired while competing against an early riser before 8 am.

Social jetlag:

Other factors, such as travel, may also impact one’s ability to perform well. Travelling across time zones throws our internal clocks for a loop and necessitates some recuperation time. A condition known as “social jetlag” might affect a person’s ability to perform at their best. The tiniest of margins could make a difference between getting a medal and starting to come for last place in such an athletic competition. Morning larks did better earlier in the day, whereas the shift workers performed much better later.

Larks are favoured above owls:

We could all benefit from knowing how much our circadian rhythms affect us in our day-to-day activities. Understanding ways to maximize business or academic success efficiency might help us learn more about ourselves. Larks are favoured above owls in our society’s regular structure. As night owls can’t follow their preferred sleep/wake cycles due to the traditional working day, perhaps we should consider being more flexible.


Even if you enjoy staying up till the small morning hours or thrive in the early morning sunshine, getting enough rest is critical for your physical and mental health. An expert in the field of sleep medicine may be able to assist you to figure out why you aren’t getting enough restorative sleep, as well as suggest strategies for improving your sleep habits of lark and owl.


What kind of birds are larks?

Morning larks, another common name for early birds, are a prime example. People who prefer waking up tend to lose their energy rapidly in the evening.

Are lark and owl, or are they something else entirely?

On the other hand, those who identify as night owls tend to wake up later and sleep later since they get their best work done later.

What kind of bird are you?

Sleep experts use the term “chronotype” to describe the average time people go to bed and wake up. Early risers are called “larks,” while late sleepers are called “owls.”
