Sunbathing & Skin Care Properly
Sunbathing is beneficial for health but also has the potential to cause harm if not done properly.

Here are instructions from dermatologists on sunbathing and skin care.

1. Benefits of Sunbathing 🌞
   According to the American Academy of Dermatology (AAD) and the World Health Organization (WHO), sunbathing can help:
   ✅ Synthesize vitamin D – Support strong bones, enhance immunity.
   ✅ Improve mood – Sunlight stimulates serotonin production, reduces stress.
   ✅ Support the treatment of some dermatological diseases – Such as psoriasis, atopic dermatitis (according to Mayo Clinic).
2. Time & How to Sunbathe Correctly
   🔹 Best time: Before 9am and after 4pm to avoid strong UV rays.
   🔹 Reasonable sun exposure time: 10-20 minutes/day, not too long to avoid sunburn.

🔹 Skin exposure area: Arms, legs, back, face – No need to expose the whole body.

📌 Source: The American Endocrine Society recommends sunbathing 2-3 times/week to synthesize enough vitamin D
without damaging the skin.

3. Risks of Sunbathing Improperly 🚨
   ⛔ Increased risk of skin cancer – Due to excessive exposure to ultraviolet (UV) rays.

⛔ Premature skin aging – Causes wrinkles, brown spots, sagging skin (according to AAD).

⛔ Sunburn & dehydration – Can lead to skin burns, redness, and even heat shock.

📌 According to WHO, 90% of skin cancers are related to UV rays, especially due to excessive sun exposure without skin protection.

4. How to Protect Your Skin When Sunbathing 🧴
   ✅ Apply SPF 30+ sunscreen at least 15-30 minutes before going out.

✅ Wear a wide-brimmed hat, wear sunscreen, and wear sunglasses to protect your eyes.
✅ Drink plenty of water to avoid dehydration due to the heat.
✅ Moisturize after sunbathing with a cream containing Aloe Vera or Hyaluronic Acid to soothe the skin.

📌 Source: The American Academy of Dermatology (AAD) recommends reapplying sunscreen every 2 hours if exposed to sunlight for a long time.

Conclusion
🌿 Sunbathing properly helps the body synthesize vitamin D, but it is necessary to control the time and protect the skin to avoid the harmful effects of UV rays.
