Question

which precaution is most important to take for protection from the consequences of too much sun?
put on sunblock 30 minutes before going in the sun.
apply sunscreen only during the summer.
wear a hat, such as a baseball cap.
wear sunglasses that block at least 50 percent of the suns ultraviolet rays.

Explanation:

Applying sunblock 30 minutes before sun - exposure creates a protective layer on the skin. Applying sunscreen only in summer is incorrect as sun protection is needed year - round. Wearing a hat and sunglasses are good but don't fully protect the skin. Sunblock is most effective overall for skin protection from sun's harmful effects.

Answer:

Put on sunblock 30 minutes before going in the sun.
