Ihor Dubilei writes practical English-language guides for readers who want a clear way to work through a specific problem. He is based in Ukraine and publishes independently through Manual This.
His current books focus on sleep habits and recovery. The approach is simple: start with the question a reader is already asking, check the factual claims against reputable sources, then turn the useful part into steps that fit ordinary schedules.
How Manual This works
Book topics begin with real English-language search demand. Search data helps define the question, but it does not decide the answer. Each book and article is edited for accuracy, plain language, and practical use. Health material stays educational and points readers toward qualified care when symptoms fall outside everyday habit changes.
Why the companion library exists
A book can explain a complete method. A reader may still arrive with one narrow question about waking at night, a sleep score, caffeine, sound, or stress. The articles answer those questions directly and show where the longer guide can help.
