It enhances quality of sleep
Exposure to extremely cold temperatures can also support sound sleep. This is especially true for those who engage in physical activity in the evening, followed by a form of cold therapy. The better quality of sleep might even result from the pain-relief and anti-inflammatory affects from the cold therapy. Research also suggests that lowering your core body temperature close to bedtime can help you fall asleep faster.
