See the positive side: Everybody smells this bad today.

its winter in australia. and i still have this problem. well, my partner does. haha

Sometimes when that happens to me, I wear those little pine car air fresheners.

Surely it's dangerous for someone that sleep deprived to be working in an operating theatre?

Try shaving in the event you have armpit hair

Use a decent no frills anti-perspirant instead. Mitchum roll ons work really well. I find some deodorants smell fine to begin with but after a few hours really reek something nasty.

Has this happened before? Cause if not, even if it's hot, a sudden ramping up of the severity of body odor can be a sign of something wrong. You may want to see your physician, just in case.

Don't lie. I live in the same country as you. Yesterday was cold and raining. The same as it has been every day here for the last million years.

While sweating a lot is normal in these temperatures, if your sweat smells that bad despite good hygiene there might be a medical issue you'd want to get checked out.

I recommend that you try odor brands of deodorant.
