Does anyone have this feeling that diving causes our body core temperature to fall?

I used to love to be in the air-con room and at 17 degrees celsius with just shorts and sleeveless teeshirts and be very comfy...however after i started diving,i began to feel cold often and need to wear jacket into my classrooms on top of 2 shirts and a pair of jeans.:ice:

Can someone explain or at least shed some light on this ? thanks:mostlysun

Peace out and dive safely:14:
 
Get some more dives in and that will probably start to fade. What I guess is going on with you now is that you are more sensitive to temp changes. A 2 degree drop from say 80 to 78 in air is barely noticeable. Experience that same drop underwater and it's like getting smacked in the face. I find that I'm more sensitive to temp changes since I started diving as well as changes in pressure (driving up a mountain have to clear more often). But on the other hand I'm also more relaxed and seem to take things more in stride. Also tend to stop and think more before I act.
 
Has your bodyfat levels changed?

Extra activity could cause a loss in BF, leading to less insulation around your body, so you feel the cold more.

Your core body temperature won't be falling, mainly because that is REALLY bad, and you probably would have noticed considerably more problems (e.g. terminal death at an extreme). You appear to just be feeling the cold, which can be a multitude of different pysiological and psycological factors.

How long has it been since you noticed your change in temperature perception?
 
IMO, if your last dive was June but you are still noticing being cold then I don't think that your chills are diving related.
I am not a medical professional or even a scuba professional. Maybe you should post a question in the medical forum?
 
It's highly unlikely that diving has changed your brain's temperature set-point.

You may have lost weight, which is lost insulation and can make you feel colder. If you have lost muscle mass, that reduces your basal metabolic rate and also reduces the baseline heat you generate. It's also possible to develop thyroid problems, which can produce cold intolerance. And your BMR drops with age as well, sometimes with abrupt shifts, like at the beginning of one's 30's.

But it's unlikely to be related to diving, other than very indirectly.
 
Cold more easily? it's kinda the opposite ith me... I kinda got used to being cold...so while everyone's slapping on double layers of jackets in 50 degree winter nights I just stand there with flip flops and t-shirt. (I do feel cold... but it just doesn't bother me anymore, and I won't shiver so long as I keep my core temp up)

When you're in the water your core body temperature falls.. how much depends on how cold the water is. When you get out of the water your core temperature begins to rise back toward normal... and how long it takes to get there depends on how much help you give it. Drinking warm fluids... jumping in warm water... wrapping yourself in a toastie blanket etc...

There is no scientific evidence I know of to suggest a permanent lowering of core body temperature... however, I will tell you this... and this is factual.

When I was a kid, a teenager and a young adult (all before I started diving,) my normal body temperature always read 98.6 - 98.7 F. Since I started diving my normal resting temperature hovers around 97.9- 98.0 F. This is a swing of about .7 degrees.
Perhaps a doctor out there can explain this. Is it due to aging or diving or some other explainable reason? I have taken my temperature at all times of day and night just to see... and there is a consistent noticeable drop in average resting temperature.

Ideas?

quick hijack? Hot water after diving is bad. Do you know these other options are okay after diving aggressive profiles? (as relates to increased chance of DCS hit)
