Explanation:
What are the negative effects of the changes that may occur during puberty?
Hormonal changes during puberty cause acne in teens. Voice changes - Your voice will get deeper. This is sometimes called 'voice breaking' because of the ups and downs in voice tone. Hair growth - Body hair starts to grow around the pubic area, legs, under the arms and on the face.
Personal hygiene is particularly important during puberty as the body begins to produce more hormones that can increase the amount of sweat, oil and odour the body produces.
