How Can Fluorescent Bulbs Affect Your Health?

1. Contribute to Eye Disease Risk

A research paper back in 2011 looked at the health risks to the eye from fluorescent lights.

They felt that fluorescent lights might increase the risk of UV related eye diseases by up to 12%, which could lead to contributing to more cases of cataracts per year.

2. Disrupt Your Circadian Rhythm

You ultimately want a healthy melatonin hormone cycle for good circadian rhythm health.

According to this research paper, the problem with fluorescent bulbs vs incandescent bulbs is that fluorescent lights produce more blue light wavelengths that disrupts your body clock.

Disruption to you circadian rhythm can have multiple negative effects on your health like:

  • Regular difficulty falling asleep, staying asleep, or both.
  • Excessive daytime sleepiness, or sleepiness during shift work.
  • Lethargy, fatigue and feeling exhausted.
  • Reduced alertness.
  • Difficulty concentrating.
  • Impaired judgment and decision making.
  • Trouble controlling mood and emotions.
  • Aches and pains, including headaches.
  • Stomach problems, in people who have jet lag disorder.

This is why we've also talked about wearing blue light filtering glasses when working or living under fluorescent lights.

3. Negative Effects from Light Flicker

We have talked about the negative effects of flickering lights before.

People might complain that they feel more eye strain or headaches when working under fluorescent lights at work. This might be due to the flicker effect in being emitted from the light bulbs.

Research back in 1989 found that workers who were exposed ot more natural light and fluorescent lights with less flicker reported fewer negative side-effects.

4. Potential Exposure to Mercury

Compact fluorescent lightbulbs can contain a small amount of mercury, which they need in order to emit light.

This means you have a potential risk of being exposed to mercury and developing mercury poisoning. Which explains why you have to be careful when disposing of fluorescent light bulbs otherwise you might end up like this homeowner who need their house decontaminated.
