Why Do My Lips Dry Out At Night?

Lips dry out at night because all the moisture evaporates off your delicate lip skin. Drinking water doesn’t help. It’s a like a dolphin drying out when he’s out of water — giving him water to drink won’t help. Applying a barrier to prevent water from evaporating will help.

  • Use petroleum jelly (Vaseline, Aquaphor) or any lip balm that you like. Keep it at your bedside. Apply whenever you wake up.
  • Use a room humidifier and avoid antihistamine sleeping medications such as diphenhydramine.
  • Sleep with your mouth closed (not so easy, though).

Why Do Sunburns Itch?

Have you ever had a sunburn? First it hurts. Then it itches. And itches. And itches.

Why is that?

Sunburn is caused by ultraviolet (UV) radiation damage to your skin. Too much UV damages your skin cell’s DNA, and your immune system responds by killing off the bad cells. Because UV radiation doesn’t penetrate (unlike X-rays for example), it damages only the surface layer of your skin. This outermost layer happens to be loaded with special nerve fibers called C-fibers which are responsible for itch.

Itch is a mechanism to protect us against insects and other minor injuries that aren’t significant enough to register as pain. It’s our skin’s way of saying; “Hey, there’s a bug on us, get it off!” Because the damage from sunburns happens in this same surface layer, these C-fiber nerves fire furiously until the skin is healed.

Here’s how to soothe sunburn itch:

  • Try a soothing lotion such as Eucerin Calming Lotion. You can even keep it in the refrigerator for a few hours before applying it for cool, soothing relief.
  • Lukewarm baths with colloidal oatmeal can also sooth and heal sunburned skin.
  • Many people also like aloe for its anti-inflammatory and soothing properties.
  • Avoid topical numbing sprays with “cane” in them. Allergies to these topical anesthetics is common, and the last thing you need is to add a raging allergic dermatitis to an already itchy sunburn — it’s an itch of Biblical proportion.
