What is Chronobiology?
Chronobiology is a multidisciplinary branch of science dealing with study of biological rhythms.The free-running biological rhythms reflect the endogenous mechanisms of cyclic temporization whose expression is morphologically seen as an internal clock called body clock.

Biological rhythms
Three types of biological rhythms found in human being namely ultradian, circadian and infradian.
Circadian rhythms relates to any biological cyclic variations with a frequency of 1 cycle in 24±4 hrs such as sleeping, feeding patterns in human being and other animals.
Infradian rhythms relates to certain biological rhythms with frequency lower than circadian rhythms such as annual migration or reproductive cycles. 
Ultradian rhythms exhibit frequency higher than that of circadian rhythms. Examples of such rhythms include hormone release, heart rate, thermoregulation, urination, bowel activity, appetiteand nasal cycle.

Genetics of biological rhythms
Biological periodicities are driven by genetic factors which causes a recursivity in a spectrum of frequencies ranging from milliseconds to years. There are at least nine clock genes that play key role in the mammalian body clock.  The temporal effect of genetic programming on genome is known as chronome. A branch of chronobiology dealing with chronome analysis is called chronomics.

Chronobiometry
Chronobiology can either be studied by use of model systems (e.g. Drosophila, Mouse, and Bat) or by means of Autorhythmometry (AR). AR is nothing but self-measurement of the biological rhythms by the subject himself. Adoption of AR, would permit the assessment of the normal situation or condition of its health for each individual. Chronobiological data can be analyzed either by inferential chronobiometry or by non-inferential chronobiometry.
Chronobiological analysis may provide us to approach risk, diagnosis and treatment dependent on dynamics of time, gender, age, ethnicity and geographical location of the patient.

Chronoptherapy
Chronobiological approach of disease diagnosis and management has a lot of untapped potential.

We need sufficient clinical data to validate this hypothesis.  Ultradian rhythms are not studied so far in details even though many vital processes are known to be ultradian in rhythmicity. We will measure and analyse nasal cycle pattern using rhinomanometry and spirometry.  Modern science is aware about nasal cycle since over a century (Kayser 1895) but without any physiological relevance associated to this unique phenomenon.

Reduction of Oxygen for a Short Duration May Reset Circadian Rhythm

Reducing oxygen is generally considered bad for the health. However, new research suggests that doing so for a short period of time may reset one’s circadian rhythm.
Most people have suffered from jet lag at some point in their lives. The cause of jet lag is simple: A disruption of the circadian rhythm. Curing jet lag is much more complex, often requiring days of slowly adjusting to a new sleep/wake cycle. However, new research in the field of chronobiology suggests that reducing oxygen for just a short period of time may reset the circadian rhythm and quickly cure jet lag as well as other circadian sleep disorders.

When Mice Get Jet Lag

While mice do not generally fly across time zones, they indeed can suffer from jet lag. Just as in humans, they can have changes in their environment like daylight savings time and the changing schedules of human caregivers. Like humans, the metabolism of mice, including how much oxygen they use, varies predictably over a 24-hour day.
The symptoms that jet-lagged mice get will sound familiar to any human who has had the disorder: fatigue, lower cognitive function and difficulty sleeping. However, when mice are given lower levels of oxygen in their air for a short period of time just before a large disruption to their circadian rhythm, they appear to adapt almost immediately with none of the side effects common to jet lag.

HIF1α and a Cell’s Oxygen Needs

Researchers quickly determined that HIF1α is the protein responsible for this response to low-oxygen environments. HIF1α is a protein that tells cells how to use oxygen and even how much to use. It also appears to be involved in a variety of other cell processes, many of which are oxygen-dependent. Mice that had the gene for this protein disabled did not respond to changes in oxygen levels with a reset circadian rhythm as fully-functional mice did.

Could Low Oxygen Levels Reset 

Circadian Rhythm in Humans?

Human lives are generally more complex than those of mice. We have a variety of circadian rhythm complaints, from jet lag to the problems of shift work. A disrupted circadian rhythm has been linked to diseases ranging from type 2 diabetes to heart disease. In addition, jet lag can cause discomfort as people must spend days adjusting to changes similar to adjusting to changes in work schedule and even daylight savings time.
Because people also have this protein, this may have huge implications for human health. People may be able to strap on a face mask and breath low oxygen air for just a few minutes, not long enough to cause health problems, and thus reset their circadian rhythm

The worldwide experimental platform (WeP)

What is the WeP?

Biological research is - above all - for understanding how we (humans) live, stay healthy, or become ill and are healed. Usually, this involves highly controlled laboratory experiments, under artificial conditions, and using non-human subjects. We, therefore, know quite a bit about the functioning of our body but there are remarkably many ''black boxes'' remaining concerning the human species and its biology. 


One approach to correct this deficit is field research that describes and characterises human behaviour on a large scale. Despite the perception that human individuality resists characterisation, most behaviours will show a normal distribution amongst a population. Indeed, based on our decade-long experiment in studying human behaviour on the level of populations, we believe that humans - in real life - make excellent subjects for scientific studies. Perhaps the key is simply to ask the right questions in order to understand typical human behaviours. 

The WeP seeks to extend our insights concerning all aspects of human behaviour in the real world. WeP is an acronym for ''Worldwide experimental Platform'', a tool that takes research on human behaviour to the digital age, extending around the globe and into different cultures. The first stage projects on the WeP will use internet-based questionnaires to document typical, human behaviour. 

What does theWeP study? 

Field research is one of the most important tools for learning more about behaviour, physiology and genetics of plants and animals. theWeP draws on this principle to widen research into the biology of humans. The results from WeP-studies will deliver important insights for all aspects of our life, leading eventually to a better understanding of healthy lifestyles and optimal quality of life, and therefore ways to avoid illness. Surprisingly, we still know relatively little about the basic requirements that we need as biological beings, to healthy living. How much light do we need, how much movement and exercise, how much to eat? Do our needs change through the day, season or lifetime, and will this be different if one lives near the equator or towards the poles? How dependent is our behaviour, our physiology and the development of illness on where and how we live? What do humans need so that they can be as happy with their work as with their free time? These are just a small collection from many open questions for which theWeP is seeking answers. 

The WeP-Strategy

Our limited knowledge concerning the biology of humans is mostly due to the fact that most studies can research only small numbers of people. But even if hundreds or thousands of Germans, Japanese or Americans were studied, the results would still only reflect region-specific human behaviour. In addition, many studies from different parts of the world are not readily comparable due to differences in methods. The goal of theWeP planners is that each of the questions on the various WeP-projects will be answered by thousands of people across every land and culture. By standardising methods, comparisons between studies will be possible. 

All WeP projects depend purely on voluntary respondents. Each of these participants receives a personalized response, indicating how they compare with the general population world wide. Through this feedback system, people all around the world stand to learn more about the behaviour and physiology of man. 

The strategy of theWeP has several levels. The first level uses internet-supported questionnaires trying to reach as many people from as many regions as possible. At another level of theWeP, one has the opportunity to record daily behaviour in a secure, electronic diary. Finally, some subjects may have the possibility to directly measure behavioural parameters by wearing small non-invasive devices to record activity, for example, for a couple of weeks. 

The WeP promise 

With the WeP, we will create a understanding of human behaviour and physiology in general and NOT a ''transparent individual''. All results from individuals are held in the strictest of confidence. Only the results of the general population will be published/revealed, and only after applications of the strictest of scientific analysis. No details that you provide as a volunteer will be revealed to third parties, nor can they be associated in any way with you personally. At no point will theWeP database be shared with third parties, except for academic researchers who will have access to anonymous data following an application procedure whereby their scientific question is laid out. Scientists working with public academic institutions can initiate their own project using the theWeP's infrastructure. theWeP has no commercial motivation or interests, serving exclusively basic research. WeP-projects must be approved by ethics commissions and a dedicated unit of theWeP serves to guarantee security of the data. Without a strong investment into the trust of those who provide information for the project, theWeP would have no chance to live.

Melatonin and Chronobiology

Melatonin, also known as the “mother hormone of chronobiology,” is a hormone made in the pineal gland. This process is due to cues from the suprachiasmatic nucleus of the hypothalamus, which regulates the circadian rhythm. When the retinas stop sensing as much blue wavelength light, the suprachiasmatic nucleus is informed and induces the pineal gland to begin making melatonin. When the retinas sense early morning, melatonin production is ceased and hormones associated with wakefulness are made instead. This cycle helps to create a circadian rhythm, or 24-hour sleep-wake cycle.
Melatonin has a very short half-life of about 30 minutes. Because it breaks down so quickly, it must be made continuously throughout the night in order to sustain restful sleep. In people with a healthy circadian rhythm, melatonin levels rise rapidly after dark and plateau throughout the night until early morning. These high levels are essential not just for falling asleep, but for sleeping deeply and restfully. Melatonin levels then drop sharply in the early morning to allow people to wake up in response to increasing light levels.
Chronic sleep disturbance in an average of three out of seven nights raises the likelihood of heart attack, stroke, diabetes, vascular disease and medically problematic obesity considerably.
For the older, pineal gland sufficient nighttime production of melatonin is no longer possible, even when the body is exposed to complete darkness. The pineal gland is heavily supplied with blood and like other areas with vessels, it is predestined to suffer from calcification. This leads to pronounced insomnia.
Research in chronobiology has shown that maintaining melatonin cycles is important not just to restful sleep but also to overall health.
