Frequently Asked Questions
How much sleep do adults need?
Adults need 7-9 hours per night (National Sleep Foundation). Older adults (65+): 7-8 hours. Consistently sleeping less than 6 hours is associated with increased risk of obesity, diabetes, heart disease, and cognitive decline.
What is sleep efficiency?
Sleep efficiency = time actually sleeping ÷ time in bed × 100. Above 85% is good, above 90% is excellent. If you're in bed 8 hours but only sleeping 6, your efficiency is 75% — and you should address the underlying issues.
How can I fall asleep faster?
Key strategies: consistent bed/wake times, no screens 60 min before bed, cool room (65-68°F), no caffeine after 2pm, relaxation routine (reading, meditation), avoid alcohol close to bedtime (it disrupts sleep quality).
