  • Sleeping in colder environment has been shown to enhance the release of melatonin, which is critical for optimal sleep quality (1).
  • As body temperature drops, growth hormone is released and the stress hormone cortisol will also decrease. This allows for a rise in melatonin which is a powerful antioxidant and supports healthy sleep patterns (2).


  • Sleeping cold can increase the synthesis of brown adipose tissue (Brown fat), which is highly protective against metabolic disease. It also causes your body to burn more calories (3)
  • Sleeping cold increases insulin sensitivity, which lowers the risk of type 2 diabetes (4).

The chilliPAD in Australia is quite rare. I borrowed one from a friend of mine for a couple of weeks, and noticed HUGE benefits in my deep sleep scores according to my oura ring. I love using it in summer.
