A recent study conducted by Queensland University of Technology has found that toddlers exposed to more light, particularly of the artificial kind, earlier in the day are heavier. It seems that morning light exposure may increase the risk of weight gain and obesity in children. This was the first study of its kind, so the results are subject to debate. However, researchers claim that sleep patterns, physical activity, and calorie intake need to be considered too.
Childhood Obesity Facts
The prevalence of obesity in children has doubled in the past 30 years, while teenage obesity rates have quadrupled. Currently, more than 42 million children worldwide under the age of five are overweight or obese. The main causes of weight gain in kids are similar to those in adults, and include lack of exercise, poor nutrition, and genetics.
Obese children have an increased risk of high cholesterol, heart disease, and hypertension compared to those with normal weight. They are also more likely to develop pre-diabetes, bone and joint problems, and several types of cancer. Children who carry extra pounds face a higher risk of cancer and cardiovascular problems later in life. Experts claim that obesity in children is one of the most serious public health challenges of our time.
Morning Light Exposure and Weight Gain
Besides inactivity, poor sleep, and bad eating habits, light exposure may lead to weight gain in children. What’s interesting is that adults exposed to morning light tend to be slimmer. The study was conducted on 48 pre-schoolars over a two week period. Experts have used both natural light and artificial light given off by smartphones, television, tablets, and other electronic devices.
It’s no doubt that intensity and timing of light exposure influences metabolism. The next step is to figure how these findings can be used in the fight against childhood obesity. Researchers plan to conduct new studies on infants, toddlers, and teenagers.
