Sleep is our body’s way of recharging and recovering after a day’s work and activity. Sleep is important for brain function, hormone balance, recovery, mental health and performance.

A lack of sleep, or sleep at the wrong times can interfere with our lives. Sleep deficiency is linked to poor motor function, brain function and social interactions as well as a range of health issues including heart disease, kidney disease, high blood pressure, diabetes, stroke, obesity, ADHD and depression.

This is partly because sleep helps maintain a healthy balance of hormones:

  • hormones that control the feeling of being full,
  • hormones that control blood sugar levels,
  • hormones that control growth and muscle repair,
  • hormones that support sexual function and fertility stress control hormones.

OK, so sleep is critically important.

But the modern world creates a whole range of barriers to good sleep. These barriers include:

  • busy lifestyles that leave less time for sleep,
  • mobile devices and televisions in bedrooms that distract us from sleep,
  • stress and anxiety from fast and demanding lifestyles,
  • long work hours,
  • care-giving responsibilities,
  • shift work,
  • medicines that interfere with sleep and
  • training just before sleep.

There are chemical treatments that can increase the length of sleep but not necessarily the quality of sleep. These drugs can make us feel groggy or tired the following day.

The good news is that there is strong evidence that cryotherapy and infra-red sauna improve both the quality and length of sleep.

In an Australian study (Hussain et al., 2019), 83% of those surveyed reported improved sleep after using sauna.

In a European study (Douzi et al., 2019), cryotherapy reduced the number of body movements during the night, improved subjective sleep quality, objective measures of sleep quality and reduced pain.

We have anecdotal evidence from many of our Junglers that cryotherapy, or cryotherapy plus sauna improves their sleep length and quality.

Infra-red sauna relaxes your muscles and helps sweat out toxins. It reduces inflammation and pain, which can interfere with sleep. The heat cycle relaxes your muscles. The cooling down process after sauna triggers hormones that indicate that it is time to start getting ready for sleep.

Cryotherapy also reduces or eliminates pain, and stimulates the release of hormones that help you relax and indicate that it is time to get ready to sleep and will keep you asleep longer during the night.

If you want to try either or both of these activities to improve your sleep, we recommend having your treatments in the evening.
