When answering the question, “when are the best times to study?” it all comes down to an opinion. I read through an article from scholarly (Why Studying at Night is Best - Scholarly Blog) and while it did contain information on how studying at night has its benefits, it continuously uses wording that shows it depends on the person.
For example, in the introduction paragraph for the scholarly article, it states that they, “will explore why studying at night can be the best option for many individuals.” I’d like to highlight the use of the word can and the phrase for many individuals. This wording suggests that while studying at night can be more productive for some, it isn’t for everyone. Similarly to how there are plenty of articles that highlight the benefits of nighttime studying, there are also plenty that talk about the benefits of study during the day. It’s really just up to personal preference and listening to your own body.
