With the arrival of warmer weather and long days outdoors, the need to protect our skin from the harmful effects of the sun arises. While moderate exposure to sunlight is essential for vitamin D synthesis and provides benefits such as strengthen bones, boost the immune system and improve mood, excess can cause redness, burns, spots, premature aging and even more serious conditions such as skin cancer. Many industrial sunscreens include chemical compounds that can harm both the skin and the environment. Given this scenario, the option of preparing a homemade sunscreen with aloe vera It is presented as a natural, economical, and environmentally friendly alternative. Do you want to learn how to make it step by step, knowing exactly what ingredients you apply to your skinHere we explain everything you need to know.
Why protect your skin from the sun? Benefits and risks of sun exposure
The sun is a source of life and energy; its light stimulates the production of vitamin D, essential for bone, muscle, and immune system health. It also helps maintain healthy blood pressure, improve mood, and alleviate certain skin conditions such as psoriasis and acne, and even helps regulate the sleep cycle. However, prolonged, unprotected exposure to ultraviolet rays (UVB and UVA) can be dangerous. These rays damage the superficial and deep layers of the skin, causing:
- Premature aging due to collagen degradation.
- Sunburn or erythema, with redness and discomfort that may become complicated.
- Stains and pigmentation disorders persistent.
- Loss of elasticity, wrinkles and sagging.
- Increased risk of skin cancer after accumulation of sun damage.
Therefore, it is essential to use an effective sunscreen whenever we are going to be exposed, especially during the central hours of the day and when planning prolonged outdoor activities. You can complement this protection with techniques such as using solar table lamps to further reduce exposure in your home.
