VivaRays Circadian Light Harmonizing Glasses help with weight gain and food cravings by promoting healthy light and darkness cycles. Artificial light at night increases cortisol, leading to cravings for carbohydrates and sugar before bed. It also disrupts the balance between ghrelin, the hunger hormone, and leptin, the satiety hormone, which can cause weight gain. Artificial blue light at night suppresses melatonin production and delays leptin's journey to the brain, resulting in increased hunger and reduced fat-burning ability. This makes it harder to maintain healthy body weight and can disrupt sleep, leaving you feeling less rested and energized. VivaRays Evening and Nighttime glasses create an optimal light environment for relaxation and sleep by blocking harmful blue and green light frequencies. This allows your body to produce melatonin naturally, helping leptin levels function normally and reducing the likelihood of overeating. The glasses also help reduce ghrelin levels, resulting in fewer cravings for unhealthy snacks. By promoting healthy light and darkness cycles, VivaRays Evening and Nighttime glasses support a healthy weight and overall well-being, while ensuring a restful and rejuvenating night's sleep.
