World Health Day 2024: Know Why Sun Safety Is Important

Sunlight contains visible light and invisible light (infrared, causing heat and ultraviolet rays).

Ultraviolet rays damage skin, though they are an important factor in the synthesis of vitamin D in our body.

Vitamin D synthesis requires only 15 to 20 minutes of direct sunlight exposure, obtained naturally in daily life.

UV-B rays can cause temporary skin damage like sunburn and contribute to skin cancer, such as squamous cell carcinoma.

Excessive sunlight exposure can lead to sunburn or SunTan, depending on skin type and sensitivity.

To prevent skin damage, use water-resistant sunscreen with SPF 30+, wear protective clothing, and avoid sunlight between 10 a.m. and 4 p.m.

Excessive heat, especially in the summer, can lead to various health issues like fluid retention, heat rash, heat syncope, and heat stroke.

Heatstroke is the most dangerous, characterised by a body temperature of 105°F or higher.

In cases of heatstroke, immediate cooling with cold water and replenishing fluids and electrolytes are crucial.

Prevent other heat-related illnesses by staying hydrated, avoiding prolonged sunlight exposure, and limiting strenuous activities.

Wear UV-ray protective sunglasses to safeguard your eyes from harmful UV rays.

Seek medical attention if you are experiencing symptoms like dizziness, confusion, or exhaustion in hot weather.
