Luminotherapy and chronotherapy

Did you know ?

The Luminotherapy

Luminotherapy involves exposure to white light of a given intensity, for a given time and at specific times, depending on the disorder to be corrected.

By simulating daylight, it is the effective treatment used to correct certain sleep disorders linked to phase shift “circadian rhythm disorders“, as well as certain mood disorders such as seasonal depression.

The internal biological clock relies heavily on light to regulate itself and the rhythm between sleep and wakefulness. As a result, when we are subject to jet lag, the mechanism is completely disrupted.

The effectiveness of luminotherapy depends on a number of factors, including the time, duration and intensity of exposure. It acts directly on the endocrine system, regulating the secretion of certain hormones, including melatonin.


Chronotherapy is a complementary therapy to luminotherapy. It involves gradually shifting sleep schedules until the desired time is reached.


Luminotherapy regulates sleep patterns and improves sleep quality. In some cases, it can prevent drowsiness during the day, and create a feeling of well-being throughout the day. It helps to compensate for lack of light and restore vitality.


Luminotherapy lamps are covered by your basic health insurance if you have been diagnosed with seasonal depression (SAD) by a doctor. In this case, your health insurance company will refund up to Frs. 350 on the purchase of a lamp, or Frs. 1.80 per day of rental, for a maximum of 3 months per year. These amounts are subject to the annual deductible and/or the 10% co-payment.
