PEMF, red light therapy and infrared saunas often sit side by side in wellness studios, and they are easy to confuse. They use very different kinds of energy and feel very different on the day. Here is a plain English comparison to help you choose.

PEMF uses pulsed magnetic fields that pass through clothing and the body, with no heat or light. Red light therapy (photobiomodulation) shines red and near infrared light onto bare skin. An infrared sauna warms the body with infrared heaters to make you sweat. PEMF is the only one of the three that is felt as neither heat nor light, and you stay fully clothed.
- PEMF = magnetic pulses. Red light = visible and near infrared light. Sauna = heat.
- PEMF works through clothing; red light needs bare skin; saunas need heat tolerance.
- Each has its own safety list. Check before you book.
- Many people combine them, on different days or in sequence.
At a glance: how they compare
| PEMF | Red light therapy | Infrared sauna | |
|---|---|---|---|
| Energy used | Pulsed electromagnetic fields | Red and near infrared light | Infrared heat |
| What you feel | Very little, sometimes gentle tapping or warmth | Bright light, mild warmth | Heat and sweating |
| Clothing | Fully clothed | Skin exposed to the light | Swimwear or towel |
| Typical session | 30 to 60 minutes lying on a mat | 10 to 20 minutes facing a panel | 20 to 45 minutes seated |
| Key cautions | Pacemakers and implanted electronic devices, pregnancy | Eye protection, light sensitive conditions and medications | Heart conditions, low blood pressure, pregnancy, dehydration |
How PEMF works
PEMF stands for pulsed electromagnetic field. A PEMF system sends gentle magnetic pulses at low frequencies through a mat or applicator. Magnetic fields pass easily through clothing and the body, so you simply lie down fully dressed and relax.
At Energize Your Life we describe PEMF as cellular exercise: a gentle rhythmic stimulus at the level of the cell. There is no heat and no light. Most people feel very little, and many find sessions deeply relaxing. You can read exactly what happens on the day in your first PEMF session.
How red light therapy works
Red light therapy, also called photobiomodulation or low level light therapy, uses LEDs or lasers that emit visible red light (around 630 to 670 nanometres) and near infrared light (around 800 to 850 nanometres). The light needs to reach bare skin, and its effects are concentrated near the surface because light is absorbed as it travels into tissue.
Sessions are short, usually 10 to 20 minutes in front of a panel. You will need eye protection, and people taking medications that increase light sensitivity should check with their doctor first.
How an infrared sauna works
An infrared sauna uses infrared heaters to warm your body directly rather than heating the air as much as a traditional sauna. Cabins usually run at around 45 to 65 degrees Celsius, compared with 70 to 100 degrees in a traditional sauna. You sit for 20 to 45 minutes and sweat.
Heat places real demands on the body. People with heart conditions, low blood pressure, those who are pregnant, and anyone who has been drinking alcohol should get medical advice first, and everyone needs to hydrate well.
What each one feels like
- PEMF: quiet and still. You lie on a padded mat, often with a blanket, and may notice gentle tapping, tingling or warmth, or nothing at all.
- Red light: bright and warm on the skin, a little like sitting near a sunny window.
- Infrared sauna: hot and sweaty, with a strong sense of having worked hard afterwards.
How to choose
Start with what you want from the session and what your body tolerates:
- Want to rest and switch off, fully clothed, with no heat? PEMF is a natural fit.
- Interested in a short, skin focused session? Red light therapy may appeal.
- Love heat and a good sweat? An infrared sauna may suit, if your health allows.
Many people use more than one. If you do, keep sessions sensible, stay hydrated and tell each practitioner about the others. Always follow your doctor’s advice, and read who should and should not use PEMF before booking.

Frequently asked questions
Is PEMF the same as red light therapy?
No. PEMF uses pulsed magnetic fields that pass through clothing and the body. Red light therapy uses visible red and near infrared light that must reach bare skin.
Does PEMF feel hot like a sauna?
No. PEMF does not heat the body. Most people feel very little during a session, sometimes gentle tapping or mild warmth from lying under a blanket.
Can I do PEMF and an infrared sauna on the same day?
Many people do, but check with your doctor if you have any health conditions, stay well hydrated and tell your practitioner. If you feel unwell, stop.
Which is best for relaxation?
It depends on the person. PEMF is quiet, still and fully clothed, which many people find very relaxing. Others prefer the heat of a sauna.
