When experiencing fragmented sleep during a pilgrimage, practice micro-naps (10-20 min) to recharge your batteries, or longer naps (1h-1h30) in cases of significant sleep debt to limit the risks associated with fatigue.

The idea that napping is an effective recovery tool is widely supported by research. Meta-analyses (e.g., Milner & Cote) confirm that short naps improve alertness and cognitive function after sleep restriction. The claim regarding the negative effects of sleep deprivation (stress, concentration, appetite) is firmly supported by observational studies and randomized controlled trials (RCTs) demonstrating the metabolic and cognitive impact of poor sleep hygiene. The recommendation to vary duration according to need is a consistent strategy in energy management. However, it should be noted that while long naps (90 min) allow for the completion of a sleep cycle, they can sometimes induce 'sleep inertia' (a feeling of grogginess upon waking), a point not addressed here but common. The advice remains a pragmatic and safe approach for managing atypical living conditions.
