Oxygen is essential for your body. Every cell needs oxygen to produce energy. When you live under stress, age, or rest too little, your mitochondria work less efficiently. You notice this as fatigue, shorter focus, and stronger stress responses. IHHT trains your cells to function better.
During an IHHT session, the oxygen level of the air you breathe alternates between low and high levels. This may sound unusual, but it follows the same principle elite athletes use during altitude training. Your cells respond to these changes by building new mitochondria. More mitochondria mean more energy throughout the day.
The effects are clear. Studies show that six weeks of IHHT can lower blood pressure by 10 to 14 mmHg, improve how cells use oxygen, and enhance cognitive performance, especially attention and mental clarity.
IHHT also reduces oxidative stress and inflammatory markers. This makes cells more stable. Many people notice fewer energy peaks and crashes. Their energy stays steady during the day. Their mind stays clear. Their sleep becomes deeper.
When IHHT is combined with heat and cold within the Weekly Reset Protocol, your body receives a full reset. Infrared heat stimulates circulation. Cold trains the nervous system. IHHT improves the energy level of every cell. Together, they create fast and noticeable improvements in energy, recovery, and mental focus.

The science behind IHHT
IHHT affects your body at the cellular level. When you alternately breathe air with low and high oxygen levels, your body responds in the same way as during altitude training. The low oxygen phases create a mild stress stimulus. This stimulus is safe and controlled. You barely feel it, but your cells do.
During this phase, your body activates protective mechanisms. Cells start producing new mitochondria. This process is called mitochondrial biogenesis. It allows your body to produce more energy without extra effort. The high oxygen phase supports these cellular processes and helps the mitochondria function more efficiently.
Research shows that six weeks of IHHT significantly lowers blood pressure. A reduction of 10 to 14 mmHg is clinically relevant and reduces the risk of cardiovascular disease. Studies also show improvements in cognitive function, especially memory and attention. This happens because the brain is highly sensitive to improved oxygen distribution. Endurance increases as well, and the body uses oxygen more efficiently.
IHHT reduces oxidative stress and stabilizes the autonomic nervous system. Many people feel less tension in their body. Their breathing becomes calmer. Their sleep becomes deeper. This contrasts with chronic stress, where oxidative damage and cellular inefficiency increase.
Within the Weekly Reset Protocol, IHHT forms a crucial third phase. Heat from the infrared sauna opens the blood vessels, allowing oxygen to circulate more effectively. Cold stabilizes the nervous system, helping the body relax. IHHT delivers the cellular energy boost that completes the entire cycle. This creates a synergistic effect that is stronger than each element on its own.
