Stress can make someone smell badly. If you are stressed out your body tend to release toxic hormones that causes body odour. The most parts of the body where you witness body odour are; the Armpits, the mouth and the private area.
Of all the mouth and armpit are most noticeable. Private area is left for the boyfriend to suffer alone😂😎
just like Obifred said, some low grade antiperspirants can add to the gravity of this issue for armpit odour. What I usually do when i don't have access to quality antiperspirant (like Forever Ling shield, Sure Men etc), I simply apply dustin powder on my armpit. Dustin Powder works like magic!. It is cheap, absorbs well, has cooling effects, no smell and last longer than most of this market chemicals sold here and there.
Another thing i seldom do is to use Vaseline spread under my armpit. Keeps the pores sealed and unbroken. Though not as effective as Dustin Powder
For mouth Odour. That is a critical one but you must check that you don't have cavity problems first as that is usually a source of foul odor. Seal all tooth cavity issues. Brush your mouth properly Morning and night, both your teeth, tongue and upper mouth area. Then buy mouth wash to rinse off bacteria remaining.
For serious mouth odor issues, chewing of mint gum helps alot and always allow air to circulate in your mouth. Do not remain silent all the time! SILENCE STINKS 😷
