I cannot outsmart biology

For years, I had been on 6-7 hours sleep schedule; usually at the low end. Work. Train. Eat. Had coffee every day in the morning. A consistent pattern showed up:
  • Feel sleepy kind of all day. If I sit alone for 5 minutes, I could sleep immediately.
  • Lunch crash. After lunch, I cannot do anything except for a nap, from 15 to 30 minutes. Not energized afternoon.
  • Night time is tired, just want to sleep.
I thought it was normal and that was my biology. That I felt asleep/crash after lunch, no matter the size.

For a week, I changed to 7-8 schedule. Mostly over 7h30minute per night. All the mentioned pattern has gone. Feel awake all day. No lunch crash. No nap.

Sleep is elixir of life - Dr. Matthew Walker. It is true. Respect biology.
