When should your teen or tween start using skin products?

Social media and stores are full of products that promise perfect skin. Increasingly these products are being marketed to tweens and teens as well as adults. For the most part tweens and teens do not need specialized skin products — but sometimes they make sense.

Is snuff really safer than smoking?

One more reason to brush your teeth?

Do children get migraine headaches? What parents need to know

Headaches are very common in children and teens. We don't tend to think about children getting migraines, but by age 10 one in 20 children has had one. Symptoms may differ from adults and it's important for parents to understand triggers, helpful treatments, and possible red flags.

Does sleeping with an eye mask improve learning and alertness?

Our internal clocks regulate the sleep-wake cycle, and light establishes when we should feel wakeful or sleepy. Light exposure at night affects these natural processes, so researchers studied whether wearing an eye mask while sleeping might help learning and alertness.

Does drinking water before meals really help you lose weight?

If you've ever tried to lose weight, you've probably heard the advice to drink water before a meal because it makes you feel fuller and you'll stop eating sooner. It seems like a reasonable idea — but does it work? And if it doesn't, why do people think it does?

Many medications claim to relieve migraine pain, but some are more helpful than others. In a large study looking at real-world data on 25 drugs, migraine sufferers rated the most and least helpful options.

Many efforts to improve health are also good for the brain. A study of nearly 400,000 people led researchers to develop a scorecard assessing 12 factors that contribute to the risk of dementia or stroke, making it easy to see where you're doing well and where you might do better.
