Is it multiple answer?? Because if so I would pick b and d
Healthier lungs and teeth a longer life expectancy a positive role model showing that you do not have to smoke to be cool. Also you would be saving a load more of money that you could use on things that you actually need.<span />
The answer is C. Breathing exercises helps the body with the lungs and gives more oxygen to the brain to think more clearly and calmly, thus to "settle" the body/mind.
It is clearly not D because breathing exercises has no negative effects like "decreasing sense of awareness", that is just absurd.
A and B are not true and endorphins and adrenaline are not released during breathing exercises.
If you need anymore help let me know, if you liked my answer a Brainliest answer / rating would be appreciated.
