It's possible to be productive with 6 hours of sleep, but it's not ideal. When you're sleep-deprived, your mental health and physical performance are both impaired. In addition, when you have less sleep than what is recommended by the National Sleep Foundation (7-8 hours), you may experience mood swings, poor concentration, and decreased productivity. So if you're struggling to get 7 hours of sleep each night, consider trying a few strategies to improve your sleep quality, such as adjusting bedtime habits or taking naps during the day.
