Please ensure that you consider the following guidelines when preparing your manuscript:
Author writing guide
Please ensure that all of the following information is fully and correctly entered into the submission system database when making the original submission. This text should be correct for publication:
title; full author name(s); affiliation(s)*; contact email address
*(for affiliation, please include department, institution, city, country)
The text of the article should be prefaced by an indented and italicised abstract of no more than 200 words summarising the main arguments and conclusions of the article.
Please include a list of 5-6 key words after the abstract.
The Abstract and Keywords should also be added to the metadata when making the initial online submission.
The body of the submission should be structured in a logical and easy to follow manner. A clear introduction section should be given that allows non-specialists in the subject an understanding of the publication and a background of the issue(s) involved. Methods, results, discussion and conclusion sections may then follow to clearly detail the information and research being presented.
If you wish to provide a short biographical statement regarding the author(s), please provide this after the main text, but before the Acknowledgements section (if present)
Any acknowledgements should be in a separate paragraph, placed after the main text but before the reference list/bibliography.
If any of the authors have any competing interests then these must be declared. A short paragraph should be placed before the references. Guidelines for competing interests can be found here.
Ethics and consent (if applicable)
Research involving human subjects, human material, or human data, must have been performed in accordance with the Declaration of Helsinki. Where applicable, the studies must have been approved by an appropriate ethics committee and the authors should include a statement within the article text detailing this approval, including the name of the ethics committee and reference number of the approval. The identity of the research subject should be anonymised whenever possible. For research involving human subjects, informed consent to participate in the study must be obtained from participants (or their legal guardians).
Experiments using animals must follow national standards of care. For further information, click here.
All references cited within the submission should be listed at the end of the article. Full formatting details are given below.
Please ensure that your work is formatted to the journal style prior to publication. Authors are responsible for ensuring that their manuscripts conform to the journal style. Failure to apply this formatting may result in delayed publication and additional rounds of revision.
Capitalisation of titles
Please use single quotation marks except for quotes within another speech, in which case double quotation marks are used.
Acronyms & Abbreviations
With abbreviations, the crucial goal is to ensure that the reader – particularly one who may not be fully familiar with the topic or context being addressed – is able to follow along. Spell out almost all acronyms on first use, indicating the acronym in parentheses immediately thereafter. Use the acronym for all subsequent references. You do not need to spell out abbreviations for US, UK, EU, UN and DC, as in Washington, DC.
Images & Figures
Please only include images/figures if they provide key information related to your submission. Figures, including graphs and diagrams, must be professionally and clearly presented. If a figure is not easy to understand or does not appear to be of a suitable quality, you will be asked to re-render or omit it. Images that are deemed unsuitable may ultimately be removed from your piece at the editors’ discretion.
NOTE: Please supply all figures separately during the submission process, if possible in colour and at a resolution of at least 300dpi. Each file should not be more than 20MB. Standard formats accepted are: JPG, TIFF, GIF, PNG, EPS.
The same principles which apply to figures apply to tables. They should be necessary and should not repeat significant pieces of information already included in the text.
Use of footnotes/endnotes
Please use endnotes rather than footnotes (which we will refer to as ‘Notes’ at the end of the article, before ‘References’). All notes should be kept to the bare minimum and only where crucial clarifying information needs to be conveyed. Avoid using endnotes for purposes of referencing; use in-text citations instead.
Authors are asked to use bracketed citations according to the numbered citation style . Please number your citations in order of appearance, taking care to refer to previous citations by their previously given number, in order to avoid duplication. All citations must have their full details listed within the references section, in the Vancouver style. more details about the Vancouver reference style follow.
References containing works cited within an article will be listed at the end of the article, in the order of citation alongside their corresponding number. All reading materials should be included in ‘References’ – works which have not been cited within the main text of the article, but which the author wishes to share with the reader, must be cited as additional information in endnotes explaining the relevance of the work. This will ensure that all works within the reference list are correctly cited within the text.
NOTE: Please include DOIs for reference entries, where possible.

However, if following this particular system presents real difficulties then please contact the editor-in-chief at firstname.lastname@example.org so that we can consider your particular circumstances.
As part of the submission process, authors are required to check off their submission's compliance with all of the following items, and submissions may be returned to authors that do not adhere to these guidelines.
If your paper is accepted for publication, you will be asked to pay an Article Publication Charge (APC) to cover publications costs, which can normally be sourced from your funder or institution. This fee covers all publication costs (editorial processes; web hosting; indexing; marketing; archiving; DOI registration etc) and ensures that all of the content is fully open access. This approach maximises the potential readership of publications and allows the journal to be run in a sustainable way. For a breakdown of costs, please click here. Please note that Journal Circadian Rhythms includes extra pre-production checks resulting in the additional £50 charge. This is included within the APC.
Many institutions are now making funds available to support open access publications by their staff.
If you do not know about your institution’s policy on open access funding, please contact your departmental/faculty administrators and institution library, as funds may be available to you.
If published, you will receive an APC request email along with information on how payment can be arranged from Open Access Key (OAK). If you need to waive the APC, you will also have an opportunity to do it there.
If you do not have funds available to pay the APC (e.g. because your institution/funder will not cover the fee) then we may be able to offer a discount or full waiver. Please ensure that you contact the editor as early as possible should you need to discuss waiver options or the APC in general. Editorial decisions are made independently from the ability to pay the APC.
