Most Coverage, Most Benefits, Most Recovery
Your testes sit outside the body for one reason: sperm production runs a few degrees below core temperature, and it's sensitive to heat. That's basic physiology, and it's why regular sauna use raises a fair question for anyone who cares about their numbers.
This is the low-effort answer: a gel cold pack for your lap while the rest of you takes the heat. Freeze it, wrap it in a towel or your shorts, sit.
What Does the Research Say
Understand the Effects of Sauna Heat
A study by Garolla et al. (2013), published in Human Reproduction, found that regular sauna exposure was associated with temporary changes in sperm production and function in 10 healthy men. These changes reversed after sauna use stopped.
Keep Testicular Temperature in Mind
A study published in Fertility and Sterility (1990) measured scrotal temperature in 10 men and found that average temperature rose from approximately 32.7°C to 37.5°C during sauna exposure.
Explore the Science of Scrotal Cooling
Nikolopoulos et al. (2013) reviewed eight studies investigating scrotal cooling and male fertility. Although some studies suggested potential benefits, the authors concluded that the evidence was insufficient to establish a clear fertility benefit.
Targeted Cooling & Temperature Regulation
A 2021 study published in the Central European Journal of Urology found that specialised cooling underwear reduced median scrotal skin temperature by 0.7°C. However, the study did not establish that cooling during a sauna improves fertility or prevents heat-related damage.

Blue/Green Light Blocking Glasses
These lenses block short-wavelength light — blue and most of green, roughly up to 550nm. That is the part of the spectrum your circadian system is most sensitive to. Put them on about two hours before you want to be asleep and leave them on until the lights go off. Made to improve sleep quality.
625nm Red Light Bulb
A red bulb at 625nm that screws into a normal lamp. Stops putting out short wavelengths that keep you awake
Put it in the lamps you actually use after dark. It is dim and warm, made to prevent any interruptions to your sleep. Red light in the evening is one of the most repeated habits in the biohacking world.
Full Size Red Light Panel (660nm + 850nm)
A full-height panel that covers your torso, your back, or both legs in a single session. It runs 660nm red and 850nm near-infrared together — red works at the surface of the skin, near-infrared reaches deeper into muscle and joint tissue, which is why full-body panels are the ones used for recovery rather than skin alone. You stand or lie in front of it for a few minutes, and it mounts on a wall, hangs on a door, or sits on a floor stand.
Kiuas Dry Sauna
Proper Finnish dry heat, in a sauna that folds away.
Not infrared. Not steam. Radiant and convection heat off a 1500 W element — the format nearly all the long-term sauna research was built on. Almost every portable sauna sold here is one of the other two.
Up in about 20 minutes, then back in its bag when you're done.
