Sweaty hands on court? Why your racket slips and how to fix it
Long rallies, humid courts and a grip that slowly turns slick. Here is what actually happens in your palm, and seven fixes that work.

If you play tennis, padel or badminton in Indonesia, you know the feeling: the first set goes fine, then the air gets heavier, your palm gets wet and the racket starts to twist on impact. You squeeze harder to compensate, your forearm tires, and shots start flying long.
Why your hands sweat so much when you play
The palms have one of the highest densities of sweat glands on the body. When you exercise, your body cools itself by sweating, and in hot, humid conditions that sweat cannot evaporate quickly. It stays on the skin as a thin wet film.
Nerves play a part too. Many players notice their hands sweat more on big points, during tie-breaks or in tournaments, even when the weather is cool.
Why a wet palm makes the racket slip
- Less friction: sweat acts like a lubricant between skin and grip.
- A saturated grip: an overgrip that has absorbed sweat stops absorbing more and becomes smooth.
- Over-squeezing: to stop the slip you grip harder, which costs feel, speed and, over time, puts extra load on your forearm.
7 ways to keep a steady grip
- Start with clean, dry hands. Wash off sunscreen and lotion before you play. Oily skin slips faster.
- Keep your overgrip fresh. A shiny, smooth or torn overgrip cannot grip. See our guide on choosing and changing overgrips.
- Dry your hands between points. Use a towel and wristbands, and keep a second dry towel for later in the match.
- Pick the right grip type. Tacky overgrips feel great when dry but can turn slick when soaked. Very sweaty players often prefer drier, more absorbent overgrips.
- Use a grip enhancer. A grip spray with natural rosin, such as ONGrip, leaves a thin layer that adds tack without chalk dust. Two or three sprays per hand from 10–15 cm, rub in and let it dry for a moment.
- Stay hydrated and cool. Drink regularly and take shade at changeovers. An overheated body sweats more.
- Relax your hand between shots. A loose grip that tightens just before contact sweats less and gives you better feel.
When to reapply a grip spray
Reapply when your palm starts to feel slippery again, usually between games or sets on hot days. Avoid spraying right before you shake hands, and wash your hands after playing.
When to see a doctor
Some people sweat heavily even at rest or in cool rooms. If sweating affects daily life, it may be hyperhidrosis, and a doctor or dermatologist can advise on treatment. Grip products help with grip, not with the medical cause.
Quick answers
Is a towel enough? For light sweating, often yes. In long rallies the palm gets wet again within a few shots, which is where an overgrip in good shape and a grip enhancer help.
Does a grip spray leave my hand sticky? A good formula dries quickly. ONGrip uses alcohol to dry fast and glycerin to keep the skin comfortable, so it adds tack without a gummy feel.
