Our infrared light therapy delivers a precise combination of Near, Mid, and Far Infrared wavelengths for optimal dosage of heat and light - helping our clients to improve health and feel amazing!
Infrared Waves penetrate at the cellular level to...
One session will leave you feeling refreshed and rejuvenated but like with exercise, benefits increase with regular use over time.
*For optimal results, consistent use is recommended, 2-4x a week, however, once or twice a week for 4-6 weeks will provide a great jumpstart to better health.
- No awkwardness
- No sharing your space
- Just relaxation time, No Strangers!
Sessions range from 30-45 minutes...
Choose from either
*You may choose add a person for a small upcharge (see below).

Not all saunas are created equal. There are two key decisions to understand when comparing options: heat-based vs. light-based technology, and within infrared, single-spectrum vs. full-spectrum delivery.
Traditional and infrared saunas operate on different principles, and far infrared differs from full spectrum in depth and breadth of impact. If you’re evaluating them purely on temperature, you’re missing the real differentiator — the range and quality of physiological response each one is designed to produce.
Our sauna is Full spectrum sauna - meaning that it delivers near, mid, and far infrared wavelengths, while far infrared (FIR) saunas use only one portion of the spectrum.
Because full spectrum combines all three, it targets surface tissues, mid-level soft tissue, and deeper structures in one session. FIR alone primarily supports deep heating and sweating but lacks the shorter wavelengths linked to skin repair and cellular performance.
Bottom line:
A far infrared sauna is specialized.
A full spectrum sauna is comprehensive.
If your looking for longevity, recovery, inflammation reduction, skin health, and metabolic support, full spectrum is the stronger all-in-one platform.
One of the many differences between OUR infrared therapy and other infrared sauna devices is the clinical testing and studies that show the unique effectiveness, safety, and quality of Sunlighten.
AGING MARKER: Mitochondrial Dysfunction
Mitochondria are like cell engines, providing energy (adenosine triphosphate or ATP) for every part of our body. With age, these engines can wear out, causing decreased ATP, increased oxidative stress and impaired cellular energy metabolism - this is a major contributor to accelerated aging of our bodies.
Infrared light helps by boosting mitochondria with energy, improving function, and making more “engines” when necessary. This could counteract mitochondrial dysfunction, keeping cells healthy and helping to slow aging.

AGING MARKER: Cellular Senescence (Zombie Cells)
As we age, some cells become dysfunctional and stop dividing but don’t die. These “senescent” cells accumulate over time, driving inflammation and contributing to tissue damage and accelerated aging.
Infrared therapy supports cellular health by promoting circulation, aiding natural detox pathways, and encouraging healthy cellular turnover—helping the body maintain stronger, more resilient tissue function as it ages.

AGING MARKER: Chronic Inflammation
Chronic, age-related inflammation (“inflammaging”) accelerates aging and raises the risk of conditions like diabetes, dementia, and heart disease. Over time, persistent inflammation damages tissues and organs, impacting everything from cardiovascular health to brain function.
Infrared sauna therapy helps reduce inflammation by stimulating anti-inflammatory responses, activating immune cells, and easing pain. When combined with exercise and a healthy diet, the benefits are even greater.

AGING MARKER: Stem Cell Exhaustion
Stem cells are essential for tissue repair and regeneration. As we age, their activity and availability decline, slowing healing and contributing to age-related degeneration.
Infrared therapy has been shown to help mobilize stem cells from bone marrow and support circulation, assisting the body’s natural repair processes and promoting healthier aging.

AGING MARKER: Gut Dysbiosis (Imbalance)
A healthy gut depends on a balanced, diverse microbiome that supports digestion, nutrient absorption, and immune function. Dysbiosis occurs when harmful bacteria outweigh beneficial strains, leading to bloating, inflammation, and digestive discomfort.
Infrared sauna therapy supports gut health by lowering systemic inflammation and encouraging detoxification, helping restore balance and promote overall wellness.
