To protect ourselves from the light and heat of the sun, we can do simple things such as:

Light doesn’t need a medium to travel. The speed of sound through air is about 340 meters per second. It’s faster through water, and it’s even faster through steel. Light will travel through a vacuum at 300 million meters per second.

The sun is the main source of heat, warmth, and light for organisms living on Earth. Without the sun’s energy, Earth would be completely dark and freezing cold. Living organisms use heat and light from the sun. Plants need sunlight to make food.

1. We should avoid playing under the sun when it is high noon.
2. Let us not look directly to the sun.
3. Apply sunblock lotion when we go swimming.

Use hearing protection devices (such as earplugs and earmuffs) when you cannot avoid loud sounds. Make hearing protection convenient. Stash earplugs in your car or workshop for easy access. Keep children away from loud music or equipment at home.

How can I avoid the harmful effects of the sun?

1. Always wear sunscreen. Apply it on your skin every day.
2. Avoid sun in the middle of the day, from about 10 a.m. to 3 p.m. The ultraviolet rays, which cause sunburn, are strongest during this time.
3. Wear protective clothing.
4. Wear sunglasses that filter UV light.

Spending a lot of time outdoors for work or recreation without protective clothing and sunscreen increases your risk. The pattern of exposure may also affect your skin cancer risk. For example, frequent sunburns in childhood may increase the risk for some types of skin cancer many years or even decades later.

8 tips to protect yourself from the heat

1. To avoid heat-related illnesses, wear light-weight, light-colored clothing made of breathable material, like cotton.
2. Stay hydrated by drinking water throughout the day.
3. Avoid strenuous outdoor activity on hot days.
4. If you’re outside, take frequent breaks in a cool place.

How to protect your skin from the sun

• Use sunscreen every day, even if it’s cloudy.
• Apply at least one ounce of sunscreen (enough to fill a shot glass) at least 15 to 30 minutes before going outside.
• Choose a broad spectrum sunscreen that protects against both UVA and UVB radiation.
• Reapply sunscreen every two hours.

Staying inside will reduce your exposure to radiation.

1. Close windows and doors.
2. Take a shower or wipe exposed parts of your body with a damp cloth.
3. Drink bottled water and eat food in sealed containers.
