Health Tip: Heat Stroke? Get Help!

Heat stroke occurs when the body is not able to cool itself to a safe temperature. It usually happens when a person is exposed for too long to the sun, without proper shade, cooling and hydration.

The very young and the very old are most sensitive to heat and most likely to develop heat stroke, as are people who work outside and those taking certain medications, the University of Maryland Medical Center says.

Heat stroke is typically characterized by flushed, hot and dry skin. Other symptoms can include dizziness, headache, confusion, fatigue, seizure, and loss of consciousness.

Someone with heat stroke should receive professional medical attention. A heat stroke victim should be brought inside out of the sun and cooled down immediately. The skin should be wiped down with cool water and fanned to bring the body temperature down. Ice packs should be applied to the groin and armpits, and the patient should rest in a cool place with the feet slightly elevated.

Doctors often treat heat stroke victims with intravenous fluids. Bed rest is usually recommended.

Health Tip: Help Your Child Get a Good Night's Sleep

If you're struggling with getting your child to go to sleep or stay asleep, the National Sleep Foundation recommends setting a nightly routine.

Children should have a standard bedtime that you stick to every night of the week. Leave plenty of time for them to get ready for bed and to finish the preparatory routine.

You may want to give your child a light snack after dinner and before bed, according to the foundation. After snack time should be bath time, then it's time to put on pajamas and brush his teeth. A bedtime story is a good way to wind down and prepare your child for sleep. When it's time for him to go to sleep, make sure the room is quiet and dark, then leave the room.

The NSF also recommends that you do not go into the child's room every time he wakes in the middle of the night. Your child will begin to expect you to come to his room and will not learn to go back to sleep by himself, the foundation warns.

Migraines More Common in Overweight Kids

Children who suffer from migraine headaches are 36 percent more likely to be overweight, according to a new U.S. study.

Researchers were not surprised by the findings, as previous studies have linked obesity to migraine headaches in adults as well.

"The numbers tell us that being overweight may contribute to kids having more headaches, most often migraines," Dr. Andrew D. Hershey, director of the Headache Center and a pediatric neurologist at Cincinnati Children's Hospital Medical Center, said in a prepared statement. "There are likely a number of causes, including poorer general health, body stress, lack of exercise and nutrition. It may not be that being overweight directly causes migraine, but that the reasons for being overweight cause these children to have worsening headaches."

Researchers evaluated 440 children between the ages of 3 to 18 who visited one of seven pediatric headache centers. Of the entire population, just over 91 percent were diagnosed with migraine headaches and close to 9 percent had other types of headaches. While 15.5 percent of U.S. children are considered overweight, more than 21 percent of headache-prone children in the study were overweight, the researchers said.

Severity of headaches was also examined and calculated on a scale where a score of between 30 and 50 signified moderate disability due to headache. Children who were overweight had an average score of 41.9, those at risk of being overweight a score of 42.9, and children of normal weight a score of 28.7.

Results of the study were to be presented at this week's annual meeting of the American Headache Society, in Los Angeles.

"Obesity is a state of chronic, low-degree systemic inflammation," study author Dr. Marcelo E. Bigal, director of research at the New England Center for Headache in Stamford, Conn., said in a prepared statement. "Most of the inflammatory markers that are elevated in obese people also play a role in the inflammation of blood vessels in the brain that occurs during migraine attacks. Being a pro-inflammatory state, obesity may increase the chances of migraine attacks in people who are biologically predisposed to suffer from migraines."
