Brief Answer:
Needs adjustments and some work up if persists.

Detailed Answer:
Thank you for asking

I read your question and i understand your concern. Sweating between breast folds only mild is likely due to environmental causes like tight bras, heat, moisture, lack of air circulation, friction between skin folds of breast , humidity , obesity or enlarged breasts. Apart from it hormonal evaluation should be done like thyroid to rule out any endocrine cause of increased sweating.

Meanwhile, modify the clothes, wear cotton bras, use a skin pad of cotton between breast folds, keep the area moisture free, air dry and apply some burrows solution compresses to keep the hygiene. Keep the skin as dry and cool as your can. Wear a bra with good support, If you have weight issue, conisder losing weight.

I hope it helps. Take good care of yourself and don't forget to close the discussion please.

Brief Answer:
No worries. Likely environmental cause

Detailed Answer:
Sweating occuring only during sleep is likely due to environmental factor like too warm blanket or a warm room temperature. Nutshell nothing is worrisome for just sweats between brests if you dont have any other breast symptoms like discharge , pain or color change. You may still get evaluated as we discussed earlier for the peace of mind.
I hope it helps.
