Should You Keep The AC On While Working Out?

By Dixit Arora +2 more

What are the first few things you enquire about when you want to join a new gym? The exercise equipment, the timings, and the fees. One other thing that many people ask is whether the gym is air-conditioned or not. This is because working out means a lot of sweating, which is not very comfortable. And especially in our climate, exercising without air conditioning is unthinkable to most.

So, should you keep the AC on during workouts? Let’s find out.

Should You Keep The AC On While Working Out? - PharmEasy

Here is what happens if you keep the AC on:

 1. It’s not easy to warm up

You probably know that you have to warm up before you start your exercise routine. But warming up takes a lot of time when you do it in an air-conditioned room. What does that mean? It means that you will be using a lot of energy just to warm up and you will be left with very little stamina to go through your main routine afterwards.


 2. Your body keeps cooling down

The goal of exercising is to keep your body warm because that is the only way you can burn calories. But in an air-conditioned room, your body does not stay warm for long periods and tends to cool down often. What does this imply? Your body will burn fewer calories even though you exercise for long periods. 

When you take quick breaks in between sets, your body will lose heat due to the AC. And when you resume your workout, you will have to work extra hard to warm up your body again. At the end of the session, although you will be left exhausted, you will have burnt fewer calories than expected.

 3. You will not lose toxins

One of the chief benefits of working out is detoxification. Your body gets rid of harmful substances through sweating. The more you sweat, the cleaner your system becomes. But how much do you sweat when you work out in an AC gym? Not much! So that means, your body will not be able to expel many toxins.

 4. Not suitable for a cardio workout

What is the purpose of a cardio workout? It makes your heartbeat faster, which in turn generates heat to burn up the calories. And normal temperatures are ideal to gently escalate your heartbeat to the required level. But in a cold room, you won’t be able to generate an adequate amount of heat to burn a lot of calories.

Working out in an AC gym also causes a lot of muscle aches and muscle tears.

 5. You can catch a cold

After a long stretch of exercise, you take a small break, right? If you are in an air-conditioned room, your body will cool down more rapidly than it is supposed to and this will dry all your sweat almost immediately – this makes you prone to catching a cold. 

Moreover, cooling down during breaks in an AC room and warming up multiple times during a workout is bad for your heart because it has a negative impact on your blood pressure.

Potential Downsides Of Not Using An AC During Workout

The solution, however, is not as clear as we have been suggesting. Working out without air conditioning can have its own impacts. One important factor to consider is that not everyone everywhere is experiencing the same climate. If you live in a hot, humid climate overheating may be a real issue. Overheating during a workout may result in feeling breathless and even an inability to exert yourself fully. This can be both harmful to your health and make your workout redundant. 


It should be noted that sweating does not have a lot to do with getting a good workout, sweat is your body’s way of managing body heat. Some people sweat a lot while others sweat less. What most trainers say is important is to work out consistently, safely and with ample fresh air from your surroundings. Working out with or without air conditioning may affect different people in different ways. The end result (according to most trainers) is usually the same, neither one is going to make you increase muscle mass faster. To ensure the best results, you need to find somewhere that is convenient for you, this will help with keeping your routines consistent.  

Always use the advice and help of a trained professional if you plan on performing an intense workout routine. Whether you’re in a gym or room with AC or not, be watchful of your body temperature and your breathing. If you find yourself experiencing any issues, stop and assess the situation.
