The Truth: Weekend catch-up sleep doesn’t truly pay off your “sleep debt” from the week. In fact, it can disrupt your circadian rhythm and increase health risks. The real solution? Consistent routines + science-backed sleep management — not emergency catch-up naps. A study from the University of Pennsylvania found: “Even with 10 extra hours of sleep on weekends, cognitive performance doesn't fully... Lire plus...

The LUUNE Sleep Lab | Can’t Sleep? Blue Light Sabotages Your Melatonin
Blue Light: The Overlooked "Sleep Assassin" ⚠️ The Stealth Attack of Electronic Devices When you scroll through your phone late at night, blue light at 450-500nm wavelengths aggressively suppresses melatonin production: 50%+ Melatonin Reduction: A University of Haifa study confirmed that 2 hours of screen exposure before bed halves melatonin secretion, delaying sleep onset by 40 minutes. Sleep Fragmentation: Blue light exposure causes 7.6 unconscious awakenings per night (vs. 4.5 in red light groups), fracturing deep sleep into "chopped filling." Metabolic Disruption: Russian research linked blue light exposure between 21:30-1:00... Lire plus...
