Short German-language excerpt from a Niraj Naik YouTube video about sleep quality. The speaker advises checking which nostril is more active immediately upon waking: sustained morning left-nostril dominance is presented as an indicator of insufficient sleep. The speaker suggests a corrective action involving shifting 'sleeping with the left hemisphere' and then engaging the right hemisphere when getting out of bed (a technique to rebalance brain activity for better rest).
