How does sun exposure affect skin?

Ultraviolet (UV) rays can cause damage to your skin
Ultraviolet (UV) rays can cause damage to your skin and it’s DNA, resulting in early aging and an increased risk of skin cancer.

It doesn’t have to be sunny either, and UV damage is possible on overcast days too.

Sunshine can have both positive and negative effects on your skin, depending on the amount of exposure and protective measures taken. Here's a breakdown:

Positive effects:
Vitamin D production: Sunlight is a natural source of vitamin D, which is essential for overall health. When your skin is exposed to UVB rays from the sun, it can produce vitamin D, which plays a crucial role in calcium absorption and bone health.

But you only need a little sun to give you all the Vitamin D you need.

So, stay out of the sun when it’s hottest, and get a little sunshine in the cooler times of the day –particularly in winter, when Vitamin D levels can get low!

Sunshine also helps you create Vitamin D which is important for mood, immunity and bone strength.

Negative effects:
Sunburn: Excessive sun exposure, especially without protection, can cause sunburn. Sunburn is a painful condition characterized by red, inflamed skin that can blister and peel. It increases your risk of skin cancer, particularly melanoma.

Premature aging: Prolonged exposure to UV radiation from the sun can lead to premature aging of the skin. This includes wrinkles, fine lines, age spots, and a loss of skin elasticity.

Skin cancer: UV radiation is a known carcinogen and is the primary cause of most skin cancers, including melanoma, basal cell carcinoma, and squamous cell carcinoma. Overexposure to the sun, especially with a history of sunburn, can significantly increase your risk of skin cancer.

Damage to skin cells: UV radiation can damage the DNA in skin cells, which can lead to mutations and the development of cancerous cells over time.

To protect your skin while enjoying the benefits of sunshine, follow these recommendations:

Use sunscreen: Apply broad-spectrum sunscreen with an SPF of at least 30 to exposed skin, even on cloudy days.

Wear protective clothing: Cover your skin with long-sleeved shirts, wide-brimmed hats, and sunglasses with UV protection.

Seek shade: Limit your time in direct sunlight, especially during peak UV hours (usually between 10 a.m. and 4 p.m.).

Avoid tanning beds: Tanning beds emit UV radiation and can increase your risk of skin cancer and premature aging.

Regular skin checks: Perform self-exams of your skin and see a dermatologist for regular skin screenings to detect any potential skin issues early.

Pakistan's veteran all-rounder and former skipper Shahid Afridi has finally reacted to Indian star batter Virat Kohli's remarks on playing in Pakistan. "I expected such a statement from Virat. I welcome Kohli, whether he comes to the Pakistan Super League (PSL) or with the Indian team," Afridi said while speaking during a tape ball event in Karachi on Saturday. Afridi's comments refer to Kohli's remarks, while speaking to Pakistani mountaineer Shehroze Kashif, wherein he said that he hopes to visit Pakistan "soon". "Give my regards to your family and all your friends. Hopefully, we [will] visit Pakistan soon [as] everyone has started visiting now," Kohli can be heard saying in the video.

How to pick a good Watermelon?

Image
Watermelon is one of the delightful fruits we eagerly await each summer to enjoy its sweet and refreshing taste. It's suitable for everyone, even those following a special diet. However, the tough rind makes it a bit of a mystery, with opening it feeling like a gamble. Here's how to choose a ripe and sweet watermelon: – Examine Stripes – The outer colour of a watermelon can hint at its inner quality. Opt for a watermelon with dark green, well-defined stripes. The lighter stripes should be a pale yellow. Additionally, choose a watermelon with a dull appearance, as a shiny rind often indicates it is not fully ripe. – Look for Yellow Spot – A yellow spot on the underside of the watermelon signifies it stayed on the ground longer to ripen. The deeper the yellow, edging towards orange, the better. This spot indicates the fruit is likely red and rich in mature fibres inside. – Check stem – To ensure a watermelon is sweet and ripe, inspect the stem. It should be dry and brow
