The first and easiest thing that you can do is invest in some very powerful antiperspirant. While deodorant minimizes the odor that your bodily emissions will cause, you will continue to sweat if you merely apply deodorant. However, if you use antiperspirant, you might be able to stop the sweating from happening altogether. This depends on just how much you sweat, since such products are not equipped to combat extremely high levels of perspiration. Still, if you are on the borderline, it may be enough, and even if it isn't, it might at least cut down on the moisture.
If you don't sweat primarily through your underarms, antiperspirant is not going to be much help. You might be a good candidate to consider taking a pill to curb your sweating. These medications, which are known as anticholinergics, can be very helpful to people with pervasive perspiration problems. However, they also come with side effects, and these can be so harmful that many doctors are hesitant to prescribe them, especially in mild cases.
Some patients have success with a procedure known as iontophoresis, which involves electric currents and lasts about 20 minutes. It is not a dangerous procedure, but it requires multiple sessions, and usually, these sessions only alleviate the symptoms rather than providing a permanent solution. Another possibility it getting Botox injections in the armpits. This can be useful, but it doesn't always provide substantial benefits, and it has more drawbacks than other methods. The process of getting the injections is painful, and it needs to be repeated several times in order to take effect. Additionally, there is a risk of infection.
Some people have discovered natural remedies for dealing with excessive sweating. For instance, baking soda is naturally absorbent and can alleviate the problems if applied to the underarms, particularly in combination with cornstarch. Other folk remedies can be found online if you do a little investigating, and while most are not permanent, they can provide temporary relief.
Another thing that you can do is wear protective layers such as underarm pads. This will not stop the sweating from occurring, but it may be able to stop its effects from being visible to casual observers. Additionally, you might try to preventative measure of avoiding situations that you know trigger the sweating. For instance, if it is stress-induced, try to avoid stressful situations as much as you can.
Excessive sweating is an unfortunate problem to have, but it does not need to be a constant source of embarrassment. By using a combination of the above methods, you can go about your workday with a greater sense of confidence.
