Abstract: A basic idea of the invention is to use different properties of light (101), such as e.g. intensity and color temperature, to influence physiological thermoregulating parameters of a vertebrate (102), for example a human being, being exposed to the light. At least one particular physiological thermoregulating parameter (e.g. skin temperature) of an individual is being measured and supplied to a controller (103) for comparison with a desired target value of the measured parameter. The property of light can then be adjusted to regulate the actual value of the thermoregulating parameter of the individual being exposed to the light. Thus, a dynamic device (100) for influencing the thermoregulation of an individual by using different properties of light is provided.
