The Moment That Feels Familiar

You grab the pull-up bar, and after only two repetitions your hand slips. Again, that sticky, damp grip. Again, that brief moment of uncertainty. After the warm-up, your shirt is already soaked as if you had been doing interval training for an hour — even though the workout has only just begun.

Many people know this feeling. And many quietly wonder: is this still normal? Or could there be something more behind it?

Sweating During Exercise: What the Body Is Actually Doing

Sweating is not a weakness. When you exercise, your body temperature rises. Your sweat glands react immediately by producing fluid that evaporates on the skin and helps regulate body temperature. The fitter you are, the more efficiently this system works — trained athletes often sweat earlier and more heavily because their bodies are highly adapted to cooling.

This process is controlled by the sympathetic nervous system. It reacts not only to heat, but also to stress, excitement, and tension. That is why some people start sweating just thinking about a heavy set of squats — before the first repetition has even started.

When Is Sweating During Exercise Normal?

Sweating during exercise is generally desirable. Normal sweat production varies significantly from person to person and depends on factors such as training intensity and duration, outdoor temperature and humidity, body weight, fitness level, and genetic predisposition.

Soaking through a T-shirt during an intense workout is completely normal. However, sweating heavily during a light walk or minimal exertion may deserve a closer look.

When Sweating Becomes an Issue: Hyperhidrosis in Sports

In some people, the sweat glands work at full capacity regardless of exertion or temperature. This excessive sweating is known as hyperhidrosis and is estimated to affect around two to three percent of the population.

During exercise, hyperhidrosis often becomes especially noticeable because several triggers occur simultaneously: physical exertion, heat, and often a social component as well. Commonly affected areas include the armpits, palms, soles of the feet, and the back.

High training intensity, emotional stress during competition or group training, synthetic non-breathable clothing, as well as caffeine or spicy foods before exercise can further increase sweating.

Sweaty Hands During Sports: The Underestimated Problem

Slippery hands during exercise are more than just uncomfortable — they can become a safety issue. In weightlifting, climbing, cycling, or martial arts, a secure grip is essential. Sweaty hands, also known as palmar hyperhidrosis, are among the most common complaints in active athletes.

In the short term, chalk (magnesium carbonate) or training gloves may help. For a more long-lasting solution, it often helps to take preventive measures before training begins. Applying an antiperspirant spray or a suitable product such as Antihydral® directly to the palms may noticeably reduce sweat production.

Choosing the Right Clothing for Heavy Sweating

People who sweat heavily should pay particular attention to their sportswear. Breathable synthetic fibers such as polyester or nylon help wick moisture away from the body and dry quickly. Merino wool naturally regulates both temperature and odor. Loose-fitting clothing improves airflow, while lighter colors or dark gray often conceal sweat marks better than medium gray tones.

Specially designed sports underwear with moisture-management properties can often make a noticeable difference in overall comfort during exercise.

What Actually Helps: Practical Solutions at a Glance

Antiperspirants – The First Step

Standard deodorants are often not sufficient for excessive sweating. Specially formulated antiperspirants are generally more effective. They work best when applied to dry skin in the evening rather than immediately before training.

Antihydral® Spray is suitable for active everyday use. It is easy to apply, dries quickly, and can be used regularly on affected areas before exercise. The formulation is designed for the needs of physically active people.

When More Support Is Needed: Antihydral® Ointment

For more pronounced cases — especially heavily sweating hands and feet — Antihydral® Ointment is used as a medicinal product. It is applied topically to the affected areas and can be integrated easily into a regular routine.

Please follow the instructions for use carefully.

When Should You See a Doctor?

If sweating during exercise significantly affects your quality of life — whether through social discomfort, safety concerns during training, or skin irritation caused by constantly damp skin — speaking with a doctor may be helpful.

Dermatologists today are familiar with a wide range of effective treatment options for hyperhidrosis.
