As you know, your body temperature is really an internal clock that keeps you awake and sleeping at certain times.
It's also really important to be aware that the rise and drop of body temperature is a hint for our body to produce the feelings of being awake or being tired.
Whenever your body temperature begins to fall, you will feel tired, lethargic, and drowsier. Whenever your body temperature rises, you will feel more energetic, alert, and be able to focus better.
Don't mistake the fall of body temperature at certain times during the day as the need to sleep. Your body temperature may rise and drop several times in the day as a response to the activities you're doing at the time.
Whenever you place big physical demands on your body, your body temperature will rise above the norm. Your body temperature will drop for a while as soon as you stop the activity.
For example, if you work an 8 hour shift at a job that requires intense activity, one might feel totally drained and ready to fall asleep when you come home at around 4 PM. What you'll actually find is that this feeling of tiredness is not a genuine desire to sleep, but rather a response from your body due to the drop of body temperature.
If you resist sleeping at this moment and provide a “wind-down” period for your body after this period, body temperature will return to normal and you will feel alert again.
In the Powerful Sleep plan, it is suggested that you nap for 10-45 minutes during your day to physically recharge yourself, it's ideal to take this nap when you experience body temperature drop as it helps you sleep. Always limit your naps up to maximum 45 minutes to avoid entering the stage of deep sleep.
After you wake up from your power nap, it's absolutely normal to feel lethargic or drowsy as your melatonin levels are higher. Get as much high intensity light as possible the moment you wake up, and make sure to MOVE your body to get your body temperature up and running again.
If you currently live a very sedentary lifestyle, your body temperature will drop very often when you're sitting around on your butt or watching TV, so if you feel tired during the day understand it’s not because you need more sleep. It's because you need LESS SLEEP and MORE MOVEMENT!
