Answers: Does getting 6.5 hours of sleep instead of 8 hours actually affect your energy levels?

• sleep tracking
• sleep duration vs energy levels
• blue light and sleep quality
• caffeine half-life and sleep
• room temperature and sleep

What it concludes

• Getting 6.5 hours of sleep significantly reduces daily energy, mental clarity, and productivity compared to 8 hours of sleep.
• Using a phone in bed delays sleep onset and exposes the brain to blue light, disrupting circadian rhythms and sleep quality.
• Consuming caffeine past lunchtime impairs sleep because half of the caffeine remains in the system after 5 to 7 hours.
• A colder room temperature prevents waking up sweaty and helps the brain transition into deep sleep more easily.
