The Science Behind Morning Wood
The occurrence of morning wood is closely linked to your sleep cycles, particularly rapid eye movement (REM) sleep. During this stage, your brain is highly active, and your body experiences several physiological changes. Hormonal shifts, specifically testosterone levels, play a crucial role in this process.
Testosterone levels naturally peak in the early morning hours, which contributes to the likelihood of experiencing morning wood. Boost testosterone?: creatine actually discusses how certain factors can influence hormone levels, but morning wood is primarily a natural biological response.
Frequency and Duration
