Can a light bulb prevent cancer? [Updated for 2021]

CLEVELAND — A group of scientists at John Carroll University developed a light bulb that removes the harmful blue rays believed to play a role in cancer.

The specially coated light bulbs give off a yellow light which doesn’t disrupt the body’s production of melatonin which helps fight cancer.

It’s been speculated that exposure to normal light at night increases the risk of cancer.

“The fact that we can use light that doesn’t contain blue means that the pineal gland can keep on working even though we have enough light to see what we’re doing,” said Dr. Richard Hensler of Lighting Innovations LLC.

More research needs to be done to prove exposure to light at night may increase a risk of cancer.
