Weight Loss If you’re looking to lose weight, Sunlighten can help. Our saunas were shown in a recent study to help reduce waistlines by burning calories while you relax in comfort. If you can maintain a healthy weight, you increase your likelihood of a longer, healthier life. When it comes to infrared heat’s ability to help burn calories, only Sunlighten saunas have been clinically shown to aid in weight loss. Results from a 2009 study indicated that Sunlighten saunas are beneficial for lowering weight and waist circumference in just a 3 month period. (1) Another study showed that 30 minute infrared sauna sessions can burn upwards of 600 calories. As the body works to cool itself in our infrared saunas, there is a substantial increase in heart rate, cardiac output and metabolic rate, causing the body to burn more calories. (2)
