Patients (and students) can be good teachers, and one recently reminded me of an important premise, as she reported feeling much better since beginning to exercise in the morning upon waking, before breakfast, before doing anything else. For her, this made sense. For approximately the other half of the population it would not.
Sunrise in Chinese medicine is Shao Yang time, the time of day that corresponds, logically, with the body’s pivot, that is the system whose responsibility it is to use cortisol to bring vital substances, such as immunological or hormonal, upwards in the body. For those of us whose cortisol spikes too quickly or too early, exercise is one way to temper this surge. Interestingly, healthy food is another way. While physical movement can clear some of the inflammatory heat associated with morning cortisol, a proper breakfast of protein, unrefined sugars, and/or healthy fats can also act as an anchor to prevent it from spiking so much in the first place. For the types of people more prone to insomnia, hyperactivity, and fast metabolisms, it seems a moderate morning workout shortly followed by breakfast might be ideal.
For the opposite body type, prone to hypersomnia, chronic fatigue, and/or weight gain, a better time to exercise might be the time of day associated with the most “yang qi,” or warmth, closer to 12 noon, as these people tend to be more lacking in cortisol, as well as other excitatory chemicals, and therefore will benefit more by moving in accord with the environmental nature around them.
For those of us with small children at home, who cannot exercise upon waking, or those with jobs that preclude us from exercising just before lunch, I recommend doing what you can. Everyone is busy, but if you can find 15-30 minutes/day to get in your preferred form of movement, almost every scientific study on the subject since the beginning of scientific studies corroborate the benefit.
