How to wear a sauna hat and care for it afterwards
Updated: October 2026
You have changed, showered and reached the hot-room door, but the hat in your hand did not come with a clear answer: dry or damp? Knowing how to wear a sauna hat begins with the care line for that specific product, because UK makers give genuinely different instructions. Some say wear wool felt dry; a banya operator suggests a light cool-water dampening. Neither approach makes it safe to ignore how you feel in the heat. Our [sauna hat comparison](/hub/steam-baths/sauna-hat) records which listings mention care; this guide takes you from putting the hat on to drying it without distorting the felt.

Dry, or only lightly dampened
Several UK wool-hat makers advise starting dry. Dry felt holds air within its structure, while a soaked hat becomes heavier and may stop behaving as the maker intended. Amurr says not to soak the hat. Heartwood also says not to wet its hat before use. If your sewn-in label or product instructions use that rule, put the dry hat over dry or towel-dried hair before you enter the hot room.
Banya No.1 gives a different method: lightly dampen the hat with cool water, then rinse and air dry it after use. That advice belongs to its own banya context and should not be blended into an instruction to saturate every hat. “Lightly damp” is not “dripping wet”.
Follow the maker of the item you own. If the listing says dry, wear it dry; if it explicitly permits light dampening, use only enough water for that method. For help choosing a listing with clearer care wording, see the wool sauna hat buying guide.
During the session
Put the hat on before you settle on the bench, rather than waiting until your head already feels excessively hot. Cover the crown and, if the shape permits, your ears; place long hair inside without pulling the opening painfully tight. The hat should sit securely when you turn your head.
A steam room can load more water into felt than a dry sauna, so a hat that begins comfortable may become heavy. Take it off if it feels oppressive, catches on a ceiling or causes discomfort.
Leave the room and cool down if you become dizzy, nauseous, unusually weak, confused, very thirsty or develop a headache. NHS guidance says someone with heat exhaustion should be moved to a cool place, cooled and given fluids, and should begin to feel better within about 30 minutes. Seek NHS 111 advice if symptoms do not improve; call 999 for signs of heatstroke such as confusion, loss of consciousness or a very high temperature.
After the session
Remove the hat when you leave the hot room and let heat and moisture escape. If the maker says to rinse it, use the stated method; otherwise, do not invent a full wash after every session.
Reshape the hat while it is damp. Smooth the crown and brim with your hands without wringing, twisting or stretching the opening. A hook is convenient for a hat that is only slightly damp, but a saturated wool hat is heavier and can lengthen or distort when suspended from one point. Sauni reviewers specifically report that hanging the wet beanie changed its shape until it was washed again and laid flat.
For a thorough clean, first read the sewn-in label. Heartwood recommends a tepid hand wash and flat drying for its wool hat; Amurr says no tumble dryer or hot wash. Dry the hat completely before storing it, away from direct high heat.
If the listing never told you
An absent care line creates uncertainty, especially when the material is described only as felt. You cannot assume pure wool, and you cannot assume machine-safe synthetic fibre. The cautious choice is to contact the seller or inspect the physical fibre and care label before washing. If neither provides an answer, gentle tepid hand washing, no twisting and flat air drying present less risk than a hot machine cycle, but the uncertainty remains yours to accept.
Compare care wording alongside fibre and fit before buying, then keep those instructions with the hat. Product options for different routines are covered in our best sauna hat guide, while sauna hats for hair focuses on containing long hair.
Common questions
Do you wear a sauna hat wet or dry?
Follow the maker’s instructions. Several UK wool-hat makers say wear it dry, while a UK banya operator recommends lightly dampening its style with cool water. Do not turn either instruction into a rule for every hat, and do not soak one to remain in the heat longer.
When should you put the hat on?
Put it on before entering or as you enter the hot room, while you still feel comfortable. Arrange your hair inside and check that the hat does not obstruct your sight. Waiting until you already feel unwell is not useful; leave and cool down rather than relying on the hat.
Can a sauna hat go in the washing machine?
Only if its care label explicitly allows machine washing. Wool-felt makers commonly specify tepid hand washing and no tumble drying because heat and agitation can shrink or distort the material. When the listing is silent, ask the seller or use the physical label rather than assuming the cheapest cycle is safe.
How do you stop a sauna hat smelling?
Air it promptly after every session, never store it damp in plastic, and wash it according to its label when needed. Reshape it and let it dry completely before storage. A persistent strong smell in a new hat may be a product-quality issue, especially if correct airing does not remove it.
What if the hat has already shrunk?
Do not force it through repeated hot washes or aggressive stretching. These extracts do not support a dependable home reversal for felt shrinkage. If you followed the supplied care instructions, document the new size and contact the seller. Otherwise, replace it with a measured hat and retain the next product’s care label.
When should you leave the sauna, hat or not?
Leave if you feel dizzy, sick, weak, confused, excessively thirsty or develop a headache. Move somewhere cool and begin cooling down. NHS guidance says heat-exhaustion symptoms should improve within about 30 minutes; use NHS 111 if they do not, and call 999 for signs of heatstroke.
