@drtanyaaltmann: A new study published in the Journal of the American Heart Association directly linked extra screen time to higher blood pressure, unhealthy cholesterol and blood sugar - key warning signs for heart diseases. They also found a “screen time” metabolic signature in blood work, which are real biological changes. Kids who got less sleep had an even higher risk! This is why it’s so important to protect your child’s sleep and limit screen time. #longevityforlittles
