Screen Time and Health: Risks of Digital Pollution
Spending too much time on screens before bed can be bad for your health.
The light from phones and other devices can stop your body from making a hormone called melatonin, which helps you sleep and protects against cancer.
This can mess up your sleep and hormones.
To fix this, try turning off screens an hour or two before bed, using night mode on devices, and sticking to a regular sleep schedule.
Excessive screen time can lead to digital pollution.
Digital pollution suppresses melatonin production, disrupting sleep.
Disrupted sleep and hormone imbalance may elevate cancer risk.
Night-shift work and late-night screen use are risk factors.
Simple lifestyle changes can mitigate digital pollution's effects.
