The concept of 'sleep pressure' mentioned here corresponds scientifically to sleep homeostasis, driven by the accumulation of adenosine in the brain throughout wakefulness (reviewed in Nature Reviews Neuroscience). Evidence confirms that long or late naps decrease this pressure, delaying sleep onset (RCT study, Journal of Sleep Research). The idea of using morning light to recalibrate the circadian rhythm is also very solid, with research highlighting the crucial role of early light exposure in synchronizing the internal biological clock (meta-analysis, Sleep Medicine Reviews). While eliminating naps is a validated behavioral strategy, the exaggeration lies in the idea that it works instantly for everyone without distinction. Finally, the mention of sleep apnea as a potential cause rightly recalls that behavioral symptoms can sometimes mask deeper physiological issues. The community strongly converges toward the elimination of naps to regulate the cycle.
