The real and ugly truth is that we all use smartphones and we use the all the time! This is very bad, especially if we use them at night! The experts warn that you should be very careful and avoid using your smartphone at night, because the “blue light” that smartphones produce has been linked to some pretty serious health issues.
“Blue light is part of the full light spectrum, which means we’re exposed to it by the sun every day. However, nighttime exposure to that light, which is emitted at high levels by smartphones, tablets, laptops, and other LED screens, may be damaging your vision. It also suppresses production of the hormone melatonin, which throws off your body’s natural sleep cues.”
The night time smartphone use is linked to at least 3 serious health problems:
- Eye Damage
According to the experts, the “blue light” exposure at night has been shown to cause damage to the retina and macular degeneration (loss of central vision or the ability to see what is right in front of you). Cataract development may also be linked to blue light exposure.
- Sleep Loss
The experts warn that “blue light” disrupts melatonin production (hormone that regulates the body’s sleeping cycle). This means that without a properly regulated sleep cycle, you cannot get enough of the sleep you need. Lack of sleep or skewed sleeping cycles are associated with a whole bunch of health issues, such as:
- Heart Disease and Other Cardiovascular Problems
- Slower Response Time
- Lack of Memory Recall
- Aged Skin
- Weight Gain
- Higher Risk of Cancer
Increased light at night and resulting sleep problems have been linked to a higher rate of cancer. YES, and you’ll be shocked when we tell you that this is especially true for breast and prostate cancer. Melatonin, suppressed by “blue light,” is also an antioxidant and has been shown to be essential in the body’s natural fight against cancer. According to the experts, melatonin helps the body fight cancer and “blue light” decreases this production.
