- Sleepiness – Under normal conditions, your sleepiness should gradually increase throughout the day, peaking just before you go to bed at night. This is ideal, as you want your sleepiness to be high at the beginning of the night.
- “Noise” – refers to any kind of stimulation that inhibits or disrupts sleep. If noise is conceptually greater than your level of sleepiness, you will not fall asleep.”Noise” occurs in three zones: the mind level, body level, and the environmental level.Dr. Naiman gives this example: “If you’re energized during the day, you’re feeling passionate, you want to move, be productive and so on, that’s great. But if that experience occurs in the middle of the night, that becomes a kind of noise.”The most common type of mind noise, however, is the “cognitive popcorn;” unstoppable thoughts running through your mind at night. Examples of body noise include pain, discomfort, indigestion, side effects from prescription drugs, or residual caffeine from drinking coffee too late in the day. Environmental noise is usually obvious, such as noises in your room or house, a snoring partner (Learn about a natural snoring device) , music, lights, or a bedroom that’s too warm.
In order to get a good night’s sleep, you want your sleepiness level to be high, and the noise level to be low.
