If you're someone who can fall asleep within five minutes every night, congratulations, you don't need this tip, and everyone hates you.

  1. Place the tip of your tongue against the tissue ridge right above your upper front teeth. Keep it there for the remainder of the exercise.
  2. Exhale completely through your mouth, making a whoosh sound as you do so.
  3. Close your mouth and inhale slowly through your nose while mentally counting to four.
  4. Hold your breath for a mental count of seven.
  5. Exhale completely through your mouth for a mental count of eight. Make the same whoosh sound from Step Two.
  6. This concludes the first cycle. Repeat the same process three more times for a total of four renditions.

Breathing in for four seconds helps you take in more oxygen, holding your breath gives it a little more time to absorb into your bloodstream, and breathing out slowly for eight seconds slows your heart rate down.
