In Lazo, Russian Federation, understanding the UV Index is crucial for protecting your skin and overall health. With a climate characterized by cold winters and mild summers, residents and visitors alike should be vigilant about ultraviolet (UV) exposure, especially during peak hours when the index soars to 10 around noon. Being aware of UV levels not only helps in preventing painful sunburns but also plays a vital role in reducing long-term skin damage and the risk of skin cancer. As the sun rises higher in the sky, the UV Index fluctuates significantly—from a manageable 1 early in the morning to a strikingly high 10 by midday—making it essential to stay informed and take necessary precautions throughout the day.
At sunrise, the UV Index gently begins at 1, indicating minimal sun exposure risks. As the day progresses, it climbs steadily to 10 by noon, peaking at one o'clock. This maximum intensity signifies a strong need for sun protection, as the UV Index remains elevated at 10 until 2:00 PM. As afternoon gives way to evening, the values gracefully descend, dropping to 8 at 3:00 PM and tapering off to 4 by 5:00 PM. By sunset, the UV Index dwindles back to 1, signaling a safe return to outdoor activities. Stay alert, hydrate, and protect your skin during those peak hours!
