Goose bumps and chills in the heat..?(13 posts)

Goose bumps and chills in the heat..?shakyfish
Aug 7, 2003 10:28 AM
When riding and putting forth some heavy effort >80% for over an hour in high humidity and mid 80 heat recently I constantly get goose bumps and chills. Of course I am sweating like mad when it is that hot. I am drinking plenty of H2O and all else seems normal. Any clues what this is or where it comes from? Am I just getting delusional?

Thanks for the help..
Not drinking enough or drinking the right stuff..Dave Hickey

Try a sports drink like Gatoraid or PowerAid. It sounds like dehydration to me. It was 109 yesterday and I road for 30 miles. I stopped twice to drink a liter of Poweraid and refill my water bottle.
same thing happened to me...txcross

The heat here in Houston is a bit higher than mid 80's, high today is supposed to peak at 100+.

Anyway, same thing was happening to me about a month and half ago. I found that I was drinking too much caffeine (4-5 cups of coffee) and not enough water. I now drink one cup of coffee and at least 1.5 liters of water before my 12:00 ride.

This is my first summer riding so I am still learning, hope this helps.

I was riding around White Rock Lake in Dallas. Temps in the mid-90's with 50-70% humidity. After 25 miles or so, I got the exact same dizziness and goosebumps and my power dropped significantly. My riding buddy convinced me to pull over and try and cool off. After drinking a full bottle of water (I had already had three) I felt improved enough to make it home, but felt tired the rest of the day.

Everyone I've talked to since then has suggested that I need to drink at least two bottles per hour. Suggested mix is 1/2 sports drink to 1/2 water. I've done this on my rides this week and it's helped, but I have not done anything longer than 25 miles. The real test comes when I try and mix in a 50-60 miler in this heat.
Probably dehydration, but watch out....cory

It probably is dehydration, plus maybe mineral depletion on long rides. I remember from some long-ago First Aid training, though, that the loss of ability to regulate temperature can be the first, very early warning of a serious heat injury, including heat stroke. Nothing to worry about in itself, but it would be foolish to try to ride through it.

I get this from time to time during hard rides in hot humid conditions. I actually had goose bumps and chills on Sunday (upper 80's, near 100% humidity). It usually means the fun is about to end and I should just go home.

Heat exhaustion symptoms:
Excessive thirst
Muscle aches and cramps
Confusion or anxiety
Drenching sweats, often accompanied by
, clammy

Slowed or weakened heartbeat
NOT dehydration...KEN2

Your symptoms may be related to dehydration, but they are early warning signs of heat exhaustion. My wife has this problem (and your symptoms) because her body doesn't seem to sweat enough to keep it cool. You should get off the bike and seek shade or better yet, air conditioning, until symptoms subside.

I'm not sure this is what you had. I'm no doctor, but I had heat exhaustion once and--at least in my case--it progresses pretty quickly. I went from feeling weak & shaky to being extremely nautious in less than a minute. I became very disoriented and confused. I was babysitting a 1 year old and actually set the baby down on the floor of the store and started to walk towards the door. I had no idea what I was doing. I didn't make it even 10 steps. I blacked out and took out a display. The shop owner was great and knew exactly what to do. I was revived within minutes. But it sure was scary.

Basically, I progressed through all the symptoms and had fainted within 2 minutes. Before that I was perfectly fine. I've read that heat exhaustion occurs when your spinal column in your neck overheats. I affect the hypocampus, or something like that. Based on the fact that it can progress so quickly, you shouldn't try to keep riding. You could black out and get seriously hurt. When you have even slight symptoms of heat exhaustion you should:

A) Get off bike quickly
B) Find shade/cooler air
C) Place a cool, damp cloth on the back of your neck and in arm pits. (I've read that you should NOT use ice for this.)
D) Place your head between your knees until the nausia passes
E) Take it easy for the rest of the day
Yeah, it is heat exhaustionlnin0

I was in a MTB race with temps hitting the upper 90s and humidity to match. I was near the front following the leaders and just dripping with sweat when we finished the biggest climb of the day.

We were out of the woods at this point and the sun was beating down on us but I started to get goose bumps and began to shiver badly. I actaully believe my body stopped sweating altogether (maybe that is the clammy part).

Luckily we were warned at the start of the race about the heat and I knew something was wrong so I just sat up and slowly glided down the hill and limped back to the finish line. It was a very freakish experience and when I got back they had several others that had not been so lucky being treated for heat exhaustion.

So, if this happens I would not keep least not on the side of the road with cars. Heat stroke may be one thing but passing out into traffic is another.

happens to me on occations. Not getting proper amount of electrolytes, sweating too much and sunburn.
Thanks a ton for the advice all!!shakyfish

I normally just keep going and maybe I just get over it but it sounds like I am playing with fire here. I do have a badd tendency to push too hard alot. Which brings to mind my favorite Lance quote:

"Someone once ask me what pleasure I took in riding so long. Pleasure I said, I don't do it for the pleasure I do it for the Pain!"

in 100 degree weather. I actually got the shivers. I remember slowing down to a snails pace to get home that was twenty miles away. I suspect the start of heat stroke. I would ask your doctor if it happens a lot. Try drinking Gatorade and or taking in more potassium.

it is very very dangerous. People die everyday from this. It occurs when your body does not efficiently dissiptate heat. The reason this occurs is because your body relies on EVAPORATION of sweat to cool you. During periods of high humidity there is less evaporation (because the surrounding air is already saturated with H2O), and therefore less cooling. This cause the brain to overheat, which is very dangerous because it has evolved to operate at our normal body temperatures (98.6 deg. F). When the brain overheats the area of the brain that is responsible for activating all of the processes to cool your body (the hypothalamus...not the hippocampus) shuts down, and you can actually stop sweating...and cooling. This feeds a vicious cycle whereby cooling is impossible, and the brain shuts down, and death can ensue. Goosebumps and chills are an indication that the brain is overheating and the person needs to cool down, immediately, by any means.
