THE RESEARCH

WHAT THE RESEARCH SAYS

We don't promise miracles. Here is the research behind cold and red light — with context.

Ice bath / cold water immersion

Hormones

+250%

more dopamine (and up to +530% noradrenaline) – linked to a clearer head and more energy

How: ice bath – 1 hr whole-body immersion at 14 °C / 57 °F (lab setting)

Brown fat

23 of 24

participants showed activated brown adipose tissue under cold exposure

How: cold – 2 hrs of mild cold exposure at approx. 16 °C / 61 °F

Sick days

−29%

self-reported sick days from work compared to the control group

How: cold shower – 30 days of ending the daily warm shower with 30–90 sec of cold water

Immune response

↓ inflammation

markedly lower inflammatory response in an experimental challenge test

How: cold + breath – 10-day training combining breathwork, meditation and cold exposure

Muscle soreness

↓ soreness

less muscle soreness 24–96 hrs after training vs. no treatment

How: ice bath – cold-water immersion (approx. 10–15 °C, 5–15 min) directly after exercise

Mood

↑ mood

more positive mood and changed brain network activity right after the bath

How: ice bath – 5 min whole-body immersion at approx. 20 °C

Red light therapy / photobiomodulation

Muscle recovery

↓ soreness

less muscle soreness and signs of better strength recovery in athletes

How: red light – irradiation at 630–850 nm before or after exercise

Skin aging / collagen

90%+

of participants with measurably reduced wrinkle depth, plus higher collagen density

How: red light – 12 treatments (split-face) or 30 sessions over 12 weeks at 633 nm

Joint pain / osteoarthritis

↓ pain

short-term less joint pain and better function compared to placebo

How: red light – low-level laser therapy at appropriate doses, especially for knee osteoarthritis

Sauna / heat therapy

Cardiovascular

−50%

lower risk of fatal cardiovascular events in a long-term cohort

How: sauna – 4–7 sessions per week compared to 1 session per week

Blood pressure

↓ blood pressure

lower resting blood pressure and improved vascular function with regular use

How: sauna – regular sessions (approx. 15–20 min, 70–100 °C)

Relaxation & sleep
