Chapter 13: Personal Health Care
Lesson 1 — Skin, Hair & Nail Care
Your skin is the body's largest organ — a protective barrier against bacteria, UV radiation, and injury. Good hygiene preserves this barrier and prevents infection.
Daily WashingUse mild soap and warm water; face wash removes excess oil and prevents acne
SunscreenSPF 30+ daily protects against UV damage and skin cancer; reapply every 2 hours outdoors
Hair CareRegular washing removes dirt and oils; brush gently to prevent breakage
Nail CareTrim nails regularly; keep clean to prevent bacterial/fungal infections
Acne Facts
Acne is caused by excess oil, dead skin cells, and bacteria clogging pores — not dirt. Hormones during puberty increase oil production. Gentle cleansing and non-comedogenic products help manage it.

Lesson 2 — Dental & Eye Care
Oral health affects your whole body — gum disease is linked to heart disease and diabetes. Eyes are equally important: regular exams catch problems early.
- Brush twice daily with fluoride toothpaste for 2 minutes
- Floss once daily to remove plaque between teeth
- Dentist visits every 6 months for cleaning and exam
- Eye exams every 1–2 years; sooner if vision changes
- Screen time breaks — 20-20-20 rule: every 20 min, look 20 feet away for 20 seconds

Lesson 3 — Healthcare & Checkups
Preventive care catches health problems before they become serious. Regular checkups, screenings, and vaccinations are cornerstones of good health maintenance.
Annual Physical Exam
A yearly checkup with your healthcare provider includes height/weight, blood pressure, vision/hearing screening, and immunization review. It's your chance to ask questions about your health.

- Keep an updated health record: vaccinations, allergies, medications
- Know your family health history — many conditions are hereditary
- Be honest with your provider — confidentiality laws protect teens
- Follow through on referrals to specialists
Quick Check: Why is preventive care important, even when you feel healthy?
Lesson 4 — Consumer Health & Health Products
Being a smart health consumer means critically evaluating products, services, and information before making decisions. Misinformation is widespread — especially online.
Red Flags"Miracle cures," before/after photos, testimonials, no scientific evidence
Trusted SourcesCDC, WHO, Mayo Clinic, your healthcare provider
OTC MedicationsFollow label instructions; don't combine without checking interactions
Health InsuranceCovers medical costs; understand your plan's copays, deductibles, and network
Quick Check: How can you tell if a health product or claim is trustworthy?
