This research finding raises concern considering breast cancer is the most frequent form of cancer that affects and kills women.
Normally, when it is bedtime, our brain releases a hormone called "melatonin" that has an anti-cancer effect. Normally, we produce more of this hormone while we are sleeping.
When we are expose to light at night, it messes up with the melatonin secretion causing it's level to decrease.
Phones and computers are not the only culprit of exposure to light at night, even artificial lights such as LED light and television are offenders.
A sound sleep really helps cut down breast cancer risk, however it remains a challenge.
Working the night-shift is also a contributing factor for the development of invasive breast cancer because it messes up the body's internal biological clock.
Don't underestimate the role of sleep in our well-being. As we age, a sound good night's sleep really does play a crucial role in keeping us healthy and energized.
If you or a person you know is at increase risk of developing cancer (possibly due to family history), please share this health fact.
