Sun emits all types of lights, including blue light. Natural Blue light from the sun is responsible for our alertness and steadiness during the day. When blue light hits our eyes in the morning, melatonin hormone production is suppressed, which is our sleep hormone, and we rise.
When night falls, and the sun starts to drop, then natural blue light decreases, and it gives a signal to the pineal gland to secrete a hormone named melatonin responsible for our proper sleep.
Melatonin is also responsible for maintaining our circadian rhythm, which is our 24-hour cycle. Blue light is also emitted from computers, LEDs, and Smartphones. When we use these digital devices late in the night, we are overexposing ourselves to blue light.
When we are overexposed to blue light, melatonin hormone production is suppressed, resulting in poor quality sleep or sometimes even leads to insomnia.
If we can’t get proper sleep, we face serious mental problems. There are various types of mental health problems like anxiety, depression, and attention deficit hyperactivity disorder (ADHD).
