    Overheating in BJJ: Need a different gi? Rashguard?

    Hey y'all!

    Despite drinking a lot of water throughout my training sessions, I find myself overheating after a while (especially when rolling).

    A typical training evening for me would be one hour of standup / striking and then one hour of BJJ. I feel okay during the first hour (wearing shorts and a t-shirt) but, during the second hour (BJJ), I feel like I'm in an oven when things start getting a bit more intense. It gets so hot that I wind up getting light-headed and, after the session, I feel a bit nauseous.

    I have a gold weave gi made by Gorilla Fight Gear. Some friends have recommended that I get a single weave or summer weave gi instead but, before I spend any money, I'd like to know if you guys think it would make a noticeable difference. Underneath my gi, I usually wear dry fit shirt. Would switching to a rashguard or cotton t-shirt instead make a big difference?

    Thanks for the help!

    Go to CVS and get some Monostat.

    KIDDING! I have a gameness air gi that does really well when it's blistering hot outside, but my go-to gi is always a really thick heavy Fuji. I just kinda got used to it after a while. Granted, I don't do a lot of cardio right before I roll usually....so I couldn't speak to that specific part of your problem. Did you just start training BJJ, or have you been at it for a while?

    A multi faceted approach will be most effective. A single weave gi and a good moisture wicking rashguard will go a long way toward helping you deal with feeling overheated.

    I wonder if you get enough potassium or electrolytes?

    Don't wear a rash guard, it holds in body heat.

    I used to do JJJ that was taught by senseis who were also active competitive blues and purples in BJJ (BTT Canada) on the side so their approach to JJJ training was very similar to the average BJJ class: Warm up, learn techniques, practice techniques, spar/roll/randori (usually including takedowns and judo-style throws). So I'm used to pretty intense training sessions with a lot of rolling/randori, and I used to use the same gi back then but, now that I'm in a straight-up BJJ program at another school, I inevitably wind up overheating by the end of the class.

    One of my friends mentioned potassium and suggested coconut water. What's the link between temperature control and potassium?

    It's not the first time I see disagreement about the rashguard issue. Is there any consensus on Bullshido? If it makes a difference, I'd rather be soaked but cool than dry but overheated.

    I'd go single weave, no rash guard or t shirt. Also, if you are overheating you may be exerting yourself too much. Try talking as you are rolling. Your partner may think you are crazy but it really regulates your breathing.

    First off, how far along are you in BJJ? Months, years?

    The reason I ask is this previous summer there were days in the high 30 degree Celsius range in gi and rash guard and coped without thinking much of it other than "**** it's hot".
    GET A RED BELT OR DIE TRYIN'.

    I have nothing other than anecdotal evidence, which is obviously not valid. I wear a rashguard because my wife gives me grief about gi burn on my body. I wore cotton t-shirts underneath my gi for years before discovering Underarmour type rashguards.

    Personally, I feel that rashguards do a better job at wicking the sweat away from my body versus cotton t-shirts. Keep in mind that we're discussing personal preferences here.
