Did you know that exposing yourself to light in the evening or at night, especially to blue light created by cell phones, tablets and computers, can disturb your internal body clock? It has been proved that blue light produced by these devices can affect your sleep by inhibiting the production of melatonin, a hormone secreted by the pineal gland, which regulates your sleep. This hormone is released by the body when darkness sets in and tells your body to relax and prepare for sleep. When working at night in front of a computer, your body doesn’t get this signal and this may be the reason why it is difficult to fall asleep at night.
Here are some tricks to help you fall asleep more easily:
- Avoid using a computer after dark
- Use special glasses that block blue light
- Install software that reduces blue light
