Who wakes up at 7:00 AM

A 7 AM wake-up fits most IT and corporate jobs with flexible starts, and work-from-home days.

Your ideal bedtime is 11:15 PM. That's in step with how late most urban Indians already sleep, so the challenge is less the clock and more keeping it the same every night.

Three things that make a 7 AM alarm easier

  • Last chai or coffee by 5:15 PM, six hours before the recommended bedtime.
  • Dinner by 9:15 PM, so you're not lying down on a full stomach.
  • Phone down and lights dimmed from 10:45 PM.

Waking up at 7:00 AM: common questions

What time should I sleep if I wake up at 7:00 AM?

Go to bed at 11:15 PM to fall asleep by 11:30 PM and get five full sleep cycles (7.5 hours). For nine hours, go to bed at 9:45 PM. If you can't manage either, 12:45 AM gives you six hours, ending on a full cycle.

Is 6 hours of sleep enough if I wake up at 7:00 AM?

Six hours (four cycles) is a short night. You'll wake up between cycles, so it may feel fine at first, but most adults need 7 to 9 hours. Use the 12:45 AM bedtime occasionally, not every night.

How do I start waking up at 7:00 AM?

Move your bedtime and alarm 15 minutes earlier every three or four days until you reach 7:00 AM, keep it the same on weekends, and get daylight within 15 minutes of getting up.
