Screen Time Before Bed Affects Blood Sugar and Sleep Quality
Using phones and watching TV before bed can mess with your body.
The bright light from screens tells your brain it's still daytime and stops a special sleep helper called melatonin from being made.
When you don't sleep well, your body has a harder time managing sugar, which can make your blood sugar go up.
Even if you sleep for a while, being in light at night can make you more likely to get diabetes because it keeps your body alert and stressed.
Not getting enough sleep also makes your body less able to use insulin properly, which can cause problems like obesity and diabetes.
Sitting for too long is also bad for your body and can make it harder to control sugar.
To help your body, it’s good to move around and take breaks from sitting.
Using electronic devices before bed disrupts sleep by reducing melatonin production.
Poor sleep quality linked to screen time can lead to increased blood sugar levels.
Exposure to light at night increases the risk of type 2 diabetes.
Chronic lack of sleep can cause insulin resistance, contributing to obesity and diabetes.
Sedentary lifestyles, including prolonged sitting, also contribute to insulin resistance and poor blood sugar control.
