Sleep Expert Says Most Adults Need 7 Hours After Japan PM's 0-3 Hour Claim

Summary
Seven hours of sleep is the benchmark for optimal functioning for most adults, Johns Hopkins sleep specialist Dr. Sara Benjamin said after Japan Prime Minister Sanae Takaichi's post about getting zero to three hours a night.
Benjamin said even genetically short sleepers usually get four to six hours, and chronic sleep loss can impair performance and judgment even if people can occasionally get by on less.
Sleep trackers and apps can help if used to monitor personal patterns rather than compare with others, she said, but how a person feels remains the more important guide.
Her top advice was to keep wake-up times consistent, allow time to wind down before bed, and use short 15-20 minute naps when regular schedules leave people sleep-deprived.
Takaichi's post has drawn more than 36 million views, turning her sleep habits into a broader debate over work-life balance and how much rest adults actually need.
