Those annotations also suggest that this reduced exposure to sunlight has a negative impact on various other hormones like melatonin that regulate normal sleep cycles. This mishap has been widely publicized due to the epidemic rise of body mass index (BMI) numbers and obesity here in the United States. Inadequate levels of sleep have been linked as a major causative factor in this epidemic, which disrupts normal fat-burning and hormonal-based metabolic mechanisms. Additionally, the remarks above also hint that reduced exposure to sunlight results in a marked decline in the production of the natural steroidal nutrient vitamin D, paralleled by slower rates of growth, despite consistent workouts.
