Getting sunlight directly in your eyes can affect your overall health in powerful ways, both physically and emotionally, including your mood.

The hypothalamus is a very complex organ in the brain. It sits on top of the pituitary gland, the master gland in charge of the endocrine system. The hypothalamus connects the nervous system to the endocrine system.

It also regulates blood pressure, body temperature, circadian rhythms, hunger, thirst, fatigue, sleep and the list goes on.

By getting sunlight in naked eyes (no glasses, contacts, sunglasses or looking through windows), it travels to the hypothalamus, balancing it and making sure it performs all of its complex duties optimally for the body.

Because the hypothalamus is also in charge of emotional health, sunlight in the eyes can have a direct and immediate effect on mood. Need a lift during the day? Walk outside and get the full spectrum light of the sun in your eyes and see how your mood improves immediately, and, doing this regularly, feel how your overall health improves over time.
