The day you have to present

Short answer: Sweating on a presentation day has as much to do with nerves as with heat in the room. An undershirt beneath the shirt is the one thing that helps with both, whichever of the two is causing it.

The undershirt takes the visible part

Sweat under the arms shows clearly on a shirt, especially in a room with bright lighting. An undershirt absorbs it before it reaches the fabric and becomes visible to others in the room. See bamboo undershirt for men , and choose a skin toned style that does not show through.

The colour of the shirt

Mid blue shows the most, because the colour highlights even small marks clearly on the fabric. White and dark blue hide more and are therefore safer choices for a day with several meetings. See bamboo shirt for men , and save the lightest shirt for a calmer day.

One layer less than usual

Meeting rooms often grow warmer than expected once many people sit together in a small space. Wear one layer less than usual and keep the extra layer with you in your bag. See bamboo t shirts for men , in case you get cold along the way.

Change before you go in

If you cycled or walked to the meeting, change undershirt before stepping into the room. It takes two minutes but changes how the rest of the hour feels on your body. See bamboo underwear for men , and pack a clean set for the day.

Nerves warm you from within

Nerves before a presentation can raise body temperature just as much as a warm room can. That makes it hard to plan the sweat away entirely, however well the room is ventilated. A good inner layer at least reduces how much of it shows on the outside.

Preparing the day before

Lay out clothes the day before so the morning does not become an extra stress on top of the nerves. Check that the shirt is ironed and the undershirt is clean and ready to wear. That kind of preparation saves the minutes otherwise spent searching for clothes.

Handshakes and visible hands

Damp palms are just as bothersome as sweat marks, and they are noticed directly during a handshake. Dry hands discreetly before greeting anyone at the start of the meeting. A soft handkerchief in your bag can make a real difference here.

Water and breaks during long meetings

Long presentations with several speakers often allow short breaks between points on the agenda. Use them to drink water and breathe calmly before it is your turn again. That helps both the nerves and how warm you feel.

After the presentation

Once the presentation ends, nerves usually settle quickly, and the body starts cooling down again. If you have a change with you, this is a good moment to use it before the rest of the day's meetings begin. It gives a fresh start to the afternoon.
