It’s a good idea for parents to monitor, and limit, their children’s overall daily screen time. Here’s some advice for parents on how to manage this challenge effectively, with each child’s healthy and balanced development in mind.

A new series on Netflix about a teen’s suicide has raised concerns that it may encourage similar real-world behavior, but the show presents an opportunity for parents to talk with their children about mental health challenges and how to cope with their problems.

There is growing evidence that the placebo effect is at work in most successful medical therapies.

When you were a child, your mother or grandmother might have used a home remedy that made you feel better, especially when it was delivered with a soothing hand on the forehead or a kiss on the cheek. Perhaps she assured you that a cup of warm milk would help you fall asleep, and you found that it did.

Unbeknownst to you — or her — she was probably harnessing the placebo effect, loosely defined as a favorable response to a medical intervention that doesn't have a direct physiological effect. Although you may have learned later in life that there isn't much scientific evidence to support the practice, you may still sleep better after a cup of warm milk at bedtime.

Vaccinating babies and toddlers prevents many illnesses, but it also helps the avoid high costs associated with treating those illnesses, helps reduce sick time taken by parents, and contributes to greater immunity in a population.

The earlier one starts tanning, the longer the lifetime skin damage and the higher the skin cancer risk. As the number of people with skin cancer increases, it has become especially important to convey to teenagers the message that tanning is an unhealthy choice, whether it’s outdoors or in a tanning bed.

Even though this year’s flu season is just about over, parents should be thinking about protecting their children next winter. Despite short-term reactions in some people, the flu shot is safe for nearly everyone.

The brain's fear center may trigger inflammation and lead to a heart attack. But stress reduction techniques can break the chain.

A small, almond-shaped area deep inside the brain called the amygdala is involved in processing intense emotions, such as anxiety, fear, and stress. Now, a new brain-imaging study reveals how heightened activity in the amygdala may trigger a series of events throughout the body that raises heart attack risk.

"This study identifies a mechanism that links stress, artery inflammation, and subsequent risk of a heart attack," says study leader Dr. Ahmed Tawakol, an associate professor of medicine at Harvard Medical School. Earlier animal studies have shown that stress activates bone marrow to make white blood cells. These infection-fighting cells trigger inflammation, a process that encourages the buildup of fatty plaque inside artery walls. "But what we didn't know was, does this happen in humans? And what is the role of the brain?" he says.

Don't accept regular fatigue as part of aging.

Weariness, tiredness, lack of energy. There are many ways to describe those times when you are so fatigued you can't do anything. Often you bounce back after a quick rest or a good night's sleep, but if fatigue is occurring more often and lasting longer, it could be a sign of something more serious.

"Men may chalk up fatigue to aging, but there is no reason you should battle ongoing fatigue," says Dr. Suzanne Salamon, a geriatric physician with Harvard-affiliated Beth Israel Deaconess Medical Center. "Everyone gets tired sometimes, and your endurance may decline with age — you may not move as fast and sometimes tire quicker — but you should never be too fatigued to enjoy an active lifestyle."

Data from an annual survey show that use of illicit drugs among teenagers is in decline, and has been for some time. It’s possible that this can be partially attributed to the popularity of smartphones.

Hurting bodies and suffering minds often require the same treatment.

Pain, especially chronic pain, is an emotional condition as well as a physical sensation. It is a complex experience that affects thought, mood, and behavior and can lead to isolation, immobility, and drug dependence.

In those ways, it resembles depression, and the relationship is intimate. Pain is depressing, and depression causes and intensifies pain. People with chronic pain have three times the average risk of developing psychiatric symptoms — usually mood or anxiety disorders — and depressed patients have three times the average risk of developing chronic pain.
