Palm Cooling FAQ – How it Works and When to Use it

What makes the palms special for cooling?
The palms have glabrous skin. This skin has no hair and lots of blood vessels called AVAs. These blood vessels help the body move heat quickly from the blood to the skin. That makes the palms one of the best spots to cool down fast.

What are AVAs?
AVAs are short for arteriovenous anastomoses. They open up during heat stress and send warm blood to the skin to lose heat. The palms, soles, and face have the most AVAs.

Why does heat limit performance?
When your body gets too hot, your brain stops your muscles from working as hard. It does this to protect you from heat injury. This happens even if your muscles still have energy. This is called central fatigue.

Can palm cooling reduce central fatigue?
Yes. By cooling the blood in the hands, the body sends cooler blood back to the core. This slows the rise in core temperature. Your brain doesn’t hit the brakes as fast, so you can keep working longer and harder.

What’s the difference between skin cooling and core cooling?
Skin cooling makes you feel cooler but does not always lower core temperature. Palm cooling targets blood flow to actually remove heat from the inside. That makes it more effective than ice towels or fans.

What types of exercise benefit most from palm cooling?

• Resistance training
• Interval training
• Endurance workouts
• Team sports
• Hot or humid environments

It works best when body temperature is rising due to hard work or heat.

Can you use palm cooling in cold weather?
Yes, if the workout creates a lot of heat. Palm cooling helps with intense training even in cooler air, especially indoors or during strength work.

Does palm cooling affect muscle strength directly?
No. It doesn’t boost strength like a drug. But it helps delay the drop in strength caused by heat and fatigue. That means you can do more sets or more reps before failure.

Can it help recovery between sets?
Yes. Cooling between sets lets your body recover faster. Your heart rate drops quicker. You feel ready for the next round sooner.

Is more cooling always better?
No. Too much cooling can lower muscle temperature too much. That can hurt power if you use it right before a lift. It’s best between sets, not before max effort.

How fast does it work?
Some effects happen within 30 seconds. Cooling for 1 to 3 minutes gives the best results in most research studies.

Should I cool both hands or just one?
Both hands are ideal. But cooling even one palm gives benefits. Studies show one-hand cooling improves endurance and lowers core temperature.

Is palm cooling good for mental focus too?
Yes. Heat stress hurts memory, reaction time, and decision making. Palm cooling helps protect brain function by keeping blood flow and temperature more stable.

Do you need a special tool to do it right?
Yes. The cooling surface must stay in contact with the palm. It should stay at the right temperature and remove heat fast. Just holding an ice pack often doesn’t work well enough.
