Losing just an hour nightly can lead to significant deficits over a week.

2.Recovery Sleep Helps

Sleeping in on weekends can partially repay the debt but won't fully fix it.

3.Caffeine Masks Symptoms

You may feel alert, but reaction times and judgement are still impaired.

4.Weight Gain Correlation

5.Small Changes Matter

Going to bed just 15 minutes earlier can gradually reduce your deficit.
