The use of phototherapy lamps can effectively treat seasonal affective disorder (SAD). SAD is related to lack of sunlight in winter. Since people absorb less natural light in winter compared to sunny seasons, they experience a decline in serotonin, which is a “happiness chemical” naturally produced in our body. This can make some people feel more sleepy and depressed. When there is no phototherapy lamp in our environment, it can provide a feeling of good natural light.

Since the serotonin level of general depression patients is also usually low, this population can also benefit from the use of phototherapy lamps. These lights can even help people with sleep disorders—such as insomnia, jet lag, or simply insomnia caused by changes in work shifts—because light therapy can help regulate our natural circadian rhythm and help us fight fatigue and irritability.

This is the best phototherapy lamp to meet all your needs.
