These happy light therapy lamps deliver the safe and natural LED light our bodies need. They are perfect for improving insomnia, jet lag, seasonal blues, and more. It is simple to use, with three levels allowing you to customize the brightness for the best efficacy and comfort. The light therapy lamp mimics daylight colors to help the winter blues, regulate sleep, improve focus, boost energy, and make us feel less sad. The light keeps your internal clock on a healthy 24-hour cycle, which makes you feel more awake during the day and more likely to sleep at night. In addition, daytime exposure to bright light can suppress melatonin levels, decrease sleepiness, increase alertness, and improve performance.
