Can Pre-Workout Make You Sweat More Than Normal?
Pre-workout supplements are specifically designed to boost your performance. They stimulate your nervous system and give you energy, so you get a better workout, and taking pre-workout supplements has been linked to increased muscle growth.
Pre-workout supplements all contain slightly different variations of ingredients, but most pre-workout contains caffeine to stimulate your mind, amino acids to fight against muscle fatigue, beta-alanine, and sodium bicarbonate to reduce the amount of acidity in your muscles, nitric oxide to encourage greater blood flow, and creatine to help you lift more.
Many pre-workout supplements will also contain a thermogenic supplement. These help to boost your metabolism and promote fat burning across your body. All of this means you can work harder and perform more reps in the gym.
Sweat is a natural response to heat, and your body is designed to sweat when it gets too hot. Sweat is made up of 99% water and 1% salt and fat, and when your body is hot, the evaporation of the sweat from your skin causes your body to cool down.
The combination of the ingredients within pre-workout supplements and the impact of the pre-workout on your body can cause you to sweat significantly more than usual.
Your body temperature is raised because you're training harder, and the ingredients can also trigger your sweat glands.
Just remember that sweat production is a natural reaction to the situation, and more sweat doesn't necessarily mean there's anything wrong.

Why Does Pre-Workout Make You Sweat So Much?
1. Increased Workout Intensity
Pre-workout induced sweat is to be expected, really, because the supplement is designed to make your body work harder.
Creatine has been shown to improve your strength, and certain amino acids have been known to give you a better muscle pump. The other ingredients are also designed to benefit performance, so your exercise can go to the next level.
Your pre-workout makes your workout more intense, causing your body to burn more energy and to burn fat. This fat-burning process raises your body temperature, and your body compensates through increased sweat production.
It's natural that when you train harder, there's more sweat, but once you stop and cool down, you should reduce sweating quite quickly.

2. High Caffeine Levels Of Pre-Workout
Almost all pre-workout supplements contain a stimulant to focus your mind and give you energy, and this is one of the key ways your pre-workout supplement helps you push your body further.
Your average pre-workout will contain 150-350mg of caffeine in a single dose, which is about the same as 3 cups of coffee, so it's no real surprise that it has an impact on your body.
The levels of caffeine in pre-workout will trigger your nervous system to release cortisol and adrenaline (fight or flight hormones) because it assumes you need an extra energy boost.
These hormones can raise your core body temperature because of increased heart rate and blood flow. As a natural response to the higher body temperatures, your body starts to sweat more.
Studies have shown that the more caffeine you have, the higher your body's temperature will get. Pre-workout has a lot of caffeine, so you should expect increased sweating after taking it.

3. Pre-Workouts Can Contain Thermogenics
A thermogenic ingredient is often included within pre-workouts to speed up your metabolic rate. This raises your internal body temperature and forces your body to burn more energy, which can help people lose weight.
These are the most common thermogenic ingredients found in pre-workouts:
Capsicum is naturally found in chilies, and it gives them their intense heat, so it's no wonder your body temperature goes up and there's increased sweat production.
Studies have shown that your body reacts to the capsicum, and your metabolic rate increases even after your workout is finished. This can make you sweat for longer but can help you achieve your weight loss goals. 
CLA is a fatty acid that has been linked to weight loss. It targets fat deposits in your body and raises your temperature so that you sweat more and continue to burn calories even after you've finished exercising.
Green Tea Extract
Green tea is found in most pre-workout supplements and is associated with weight loss and fat burning. It can raise your internal temperature, and the caffeine will also help to boost your metabolism.
The mixture of caffeine and the thermogenics can lead to excessive sweating if you take a pre-workout that contains green tea.
L-Carnitine is an amino acid found in pre-workouts that impacts your blood vessels. It helps to convert fatty acids into energy, and in doing so, it generates more heat within your body. This can make you sweat more than usual, but thermogenesis can help you reach your fitness goals.
Some pre-workout brands include Yohimbe in their formula. This is a natural ingredient taken from an African tree and used as a thermogenic. It can increase adrenaline and dopamine levels, and boost your metabolism. 
All of this raises your temperature and makes you sweat more, leading to excessive sweating when combined with other ingredients in your pre-workout.
Does Sweating More Mean A Better Overall Workout?
We all know the phrase "working up a sweat." However, sweat is not an indicator of how effective your workout is.
When you're training, it's generally to grow muscle and develop your fitness. Working out in very cold conditions may not make you sweat, but you will still get all the benefits from the workout.
Does pre-workout make you sweat more? Yes, almost definitely, but it isn't the main benefit of the supplement. It's likely caused by the caffeine or other ingredients, not your performance, so don't base your workouts around sweating.
Instead, focus on your fitness goals, and the results will come.
Is Excessive Sweating During a Workout Dangerous?
Sweating is a natural reaction to heat, and it isn't likely to be harmful to your body. The only common side effect of excessive sweating is dehydration.
If you feel hot and notice a lot of sweating when you exercise, you should make sure you're drinking enough water to replace the fluids lost. This should keep your body functional and help you get the most from the gym.
It's worth remembering that some ingredients found in supplements, like caffeine, can dehydrate your body even further, so even if you're not sweating, you should make sure you have plenty of water.
Does It Detox Your Body Better?
There’s a popular belief that sweating during exercise actually flushes toxins out of your body and that it’s actually beneficial.
While exercise and working up a sweat can make you feel great, it isn’t linked to detoxification, and toxins are actually filtered out in your liver and kidneys.
However, pre-workout can help you detox your body because it contains vasodilator compounds and ingredients which boost nitric oxide production.
These open up your blood vessels and increase blood flow, allowing toxins to be filtered out from your bloodstream more quickly.

How To Reduce Excessive Sweating From Pre-Workout Intake
If your pre-workout is causing you to sweat too much, then you need to manage it proactively because it can be uncomfortable, unattractive, and lead to body odor issues. To reduce sweating, there are a few things you can do:
Choose Stim-Free Pre Workouts
Caffeine in pre-workout is one of the leading causes of increased sweating, and in high doses, it can raise your body's temperature.
It does provide mental focus, which is useful, but if you decide the sweating is too much, then you can look for some stimulant-free pre-workout which can be just as effective.

Creatine in pre-workouts can lead to a higher body temperature, but studies have actually shown that long-term use of creatine can help to balance out the other ingredients and reduce the sweating caused by caffeine.

It's important to recognize how pre-workouts will affect your body and dress accordingly. Wear loose-fitting clothes, use antiperspirant and drink plenty of water. This won't counteract your pre-workouts but will make your training more comfortable.
Frequently Asked Pre-Workout Sweating Questions
Does pre-workout cause night sweats?
The caffeine in pre-workout should leave your system after 4-6 hours, so it shouldn't really cause night sweats. However, if you're taking pre during an evening workout, or you frequently have a late night workout, then it could be causing night sweats to occur.
Try to avoid taking pre-workouts 3-4 hours before bed because it can really disrupt your sleeping pattern.

What are some other common reasons you might be sweating more?
Anxiety, pregnancy, and thyroid conditions can all cause increased sweating because of the hormones being released. They all force your body to work harder, which can lead to a rise in body temperature and increased sweating.
It's also important to consider your daily caffeine intake. An average cup of coffee contains around 100mg of caffeine, so if you're sensitive to caffeine, then it may be causing you to sweat more.

When should I be worried about excessive sweating?
Heavy sweating itself isn't anything to worry about as long as it reduces after a few hours and you stay hydrated.
However, if you experience excessive sweating accompanied by chest pain, lightheadedness, or nausea, you need to contact your doctor immediately.
Does pre-workout make you sweat more? Yes. But does it also help you get a better workout? Absolutely. The ingredients within pre-workout and the fact you can train harder means your body temperature will rise, so it's natural that you'll sweat more.
This increased sweating isn't anything to worry about, but you need to ensure you are drinking plenty of water to replace the fluids.
If the sweating gets too much to handle, then you should look to switch pre-workouts or consider lowering your dosage to see if that helps.
