As Paul says, think of sunscreen as in addition to other protection methods. So while you can go without a shirt, it's ideal to also wear a shirt and use other protection methods like a hat. As for whether clothing is always better, that in large part depends on the clothing. Some clothing provides good sun protection while others (think shirts with ...

According to this health-related website, you should still wear a shirt: You should not think of sunscreen as an alternative to avoiding the sun or covering up. It is used in addition. Sunscreens should not be used to allow you to remain in the sun for longer - use them only to give yourself greater protection. No sunscreen is 100% effective and so it ...

Smoke is a particulate, not a vapour. If you are burning something toxic, the toxins can potentially be carried by particles of smoke and be inhaled which is far ...

Seawater, no. But clean salt water, yes. Salt-water solution should be isotonic, i.e. same salt level as your body; ca ΒΌ teaspoon of sea-salt to 250 ml water. I used it on my nose piercing and it was very effective. :)

Don't scratch! Mosquitos inject an anti-coagulant under your skin as soon as they puncture you, this is to prevent the blood from clotting so their noses don't get glued to the inside of your dermis while they're sucking.
