Therapeutic light stimulation is provided to a patient through a light source, and is configured to trigger or induce resonance or high amplitude oscillations in a cardiovascular system of the patient. Inducing such oscillations or resonance can aid in training autonomic reflexes and improve their functioning. ## Claims ### Claim 1 A method of providing light stimulation therapy to a patient, comprising: identifying a resonance frequency of a cardiovascular system associated with the patient; selecting signal parameters for a light stimulation signal based on the resonance frequency of the cardiovascular system associated with the patient, wherein the signal parameters include a first time period associated with a first type of light stimulation signal, a second time period associated with a second type of light stimulation signal, and a third period that is equivalent to a combination of the first time period and the second time period and that is also equivalent to the resonance frequency of the cardiovascular system of the patient; and delivering, using a device capable of configuring light to create the first type of light stimulation signal for the first time period and the second type of light stimulation signal for the second time period, the light stimulation signal to the patient, wherein the light stimulation signal includes the first type of the light stimulation signal being successively delivered to the patient over the first time period and a second type of the light stimulation signal being delivered to the patient over the second time period, the second time period being interposed between instances of the first time period. ### Claim 2 (depends on 1) The method of claim 1, wherein the first time period is adjacent to the second time period. ### Claim 3 (depends on 1) The method of claim 1, wherein the third period of time ranges between about 8 seconds and about 14 seconds. ### Claim 4 (depends on 1) The method of claim 1, wherein the third period of time ranges between about 26 seconds and about 34 seconds. ### Claim 5 (depends on 1) The method of claim 1, wherein the first period of time ranges between about 4 seconds and about 7 seconds. ### Claim 6 (depends on 1) The method of claim 1, wherein the second period of time ranges between about 4 seconds and about 7 seconds. ### Claim 7 (depends on 1) The method of claim 1, wherein the first period of time ranges between about 13 seconds and about 17 seconds. ### Claim 8 (depends on 1) The method of claim 1, wherein the second period of time ranges between about 13 seconds and about 17 seconds. ### Claim 9 (depends on 1) The method of claim 1, wherein an electromagnetic wavelength of the light stimulation signal is in a range between 100 nm to 1 mm. ### Claim 10 (depends on 1) The method of claim 1, wherein the light stimulation signal has wavelengths ranging between about 380 nm and about 710 nm. ### Claim 11 (depends on 1) The method of claim 1, wherein the light stimulation signal has a substantially uniform wavelength during active light stimulation. ### Claim 12 (depends on 1) The method of claim 1, wherein the light stimulation signal has a substantially uniform intensity during active light stimulation. ### Claim 13 (depends on 1) The method of claim 1, wherein an intensity of the light stimulation signal is modified during active light stimulation. ### Claim 14 (depends on 1) The method of claim 1, wherein the first type of light stimulation signal corresponds to an “on” mode in which the light stimulation signal is being delivered to the patient, and wherein the second type of light stimulation signal corresponds to an “off” mode in which the light stimulation signal is not being delivered to the patient. ### Claim 15 (depends on 1) The method of claim 1, further comprising sensing a physiological parameter of the patient and, in response to such sensing, adjusting the third period. ### Claim 16 (depends on 1) The method of claim 1, wherein the resonance frequency of the cardiovascular system associated with the patient is determined based on a height and a gender of the patient. ### Claim 17 (depends on 1) The method of claim 1, wherein the resonance frequency of the cardiovascular system associated with the patient is less than about 0.125 Hz. ### Claim 18 (depends on 1) The method of claim 1, wherein the first type of light stimulation signal and the second type of light stimulation signal are delivered using a light source. ### Claim 19 (depends on 18) The method of claim 18, wherein the light source is a light bulb. ### Claim 20 (depends on 18) The method of claim 18, wherein the light source is a display of a computing device and wherein the method further comprises configuring the display of the computing device to modify a brightness of the display during active light stimulation.
