Cold and fever after doing extensive cardio sport?

Question

Every Sunday I do soccer in the morning for two hours where I run non stop and sweat extensively. After the sport I take a shower and take the bus home, but by the time I get home my dry and clean shirt becomes soaking wet as I keep on sweating.

As the day advances I am starting to get a headache, and occasionally a smallish fever by night. This happens most of the time,and I have yet to solve this issue. Should I wear more clothes? Or change shirt multiple time? I also try to drink a lot, but I have not yet found a 100% solution.

I believe this is dehydration and/or exhaustion. There are multiple message boards and online forums where people conclude this. Here is just one example I too have experienced this MULTIPLE times, usually after extremely hard workouts or prolonged endurance events. I've done multiple 24-hour ski races where I never stop during the 24-hours. I end up staying awake for close to 40 hours and by the end I am too exhausted to maintain body temperature. My two fastest marathons resulted in the same thing. I was as healthy as I could possibly be before, during and after the marathon (my results in the race prove that) but I was feverish for a few hours later in the day). I've since discovered I was never hydrating enough during my marathons and concluding I was overly dehydrated at the end of each one.

Couple of things to try:

• Are you taking a HOT shower after soccer? I've noticed if I workout/perform to exhaustion and then take a HOT shower I can have issues. My body is too tired to regulate its temperature as it normally can. If you are taking a very hot shower maybe turn the temperature down a bit.

• Hydrate a bit before, during and immediately after the workout.

• I'd also ensure you eat something within an hour after working out. The first 60 minutes after a workout of thta length are the most important for fueling. See this link for an explanation and especially note this:

"After exercise your muscles have a 'glycogen window'. This occurs 30-90 mins after you finish exercising.

Glucose (from carbs or sports drinks etc) is converted to glycogen to replenish your muscle store.

During this window, you will store glycogen at four times the normal rate.

If you want to fuel you next running session. Eat!"

If you try these three things I think your body will react better after the workout.

Answer 2

People that did a lot of exercise can have a lowered immune response, so they end up sick. Usually after many hours of working out like after marathons or ultra-marathons and so on some people get sick because their immune system doesn't have enough resources to fight off infections.

That depends on your condition - do you work out a lot, how do you eat (do you eat a normal western diet or a healthy one), do you have any medical conditions. They all can influence your immune system.

I think resting a little bit more after the training would be great. Wearing wormer clothes can't harm (unless it's too warm).

I'd also focus on food you eat which is the fuel for your body and immune system. If you usually eat processed foods, bread, pasta with just a little addition of fruits, veggies and meat I'd suggest switching the diet to more healthy one - limiting gluten intake, eating more lean meat and veggies should help in your condition.

But if you already do eat like that you should consider visiting a doctor.
