Poor grades tied to class times that don’t match our biological clocks

It may be time to tailor students’ class schedules to their natural biological rhythms, according to a new study from UC Berkeley and Northeastern Illinois University.   Students’ biological clocks often conflict with their class schedules, negatively impacting their academic performance. Researchers tracked the personal daily online activity profiles of nearly 15,000 college students as they logged into campus servers. After sorting the students into “night owls,” “daytime finches” and “morning larks” — based on their activities on days they were not in class — researchers compared their class times…

GETTING FIT UNDER WATER

Swimming pool offers relief from summer heat, and makes for an excellent exercising ground. Picture underwater squats and lunges. Exercising in the pool is a good alternative to unload the body when it fatigues from intense land-based exercises. Aqua-jogging, flutter-kicking, leg-lifts, standing water push-ups and arm-curls are some easy to do water exercises. Many pools and gyms are offering regular batches in water-boxing, aqua-step as well as introducing specialised equipment that can be used for different exercises underwater. Underwater strength training is the newest to join the water workouts bandwagon.…

Flu increases the risk of heart attack

(Reuters Health) – Influenza is already known to be deadly, but a new study suggests that the risk of heart attack is six times greater than normal while people are ill with the flu. “I was a little bit surprised by the strength of the association. It’s not every day you see a six-fold increase in the risk during the first seven days of lab-confirmed influenza,” chief author Dr. Jeffrey Kwong told Reuters Health in a telephone interview. “We were also surprised the risk dropped off to nothing by day…

KETTLEBELL WORKOUT

The kettlebell is a cast-iron or cast steel weight (resembling a cannonball with a handle) used to perform all types of exercises, including but not limited to ballistic exercises that combine cardiovascular, strength and flexibility training. They are also the primary equipment used in the weight lifting sport of kettlebell lifting.   The Russian girya (ги́ря, a loanword from Persian غران girān “heavy”) was a type of metal weight, primarily used to weigh crops, in the 18th century. The use of such weights by circus strongmen is recorded for the 19th century. They began to be used for recreational and competition strength athletics in Russia and Europe in the late 19th century. The birth…

Elimination diet

An elimination diet, also known as exclusion diet is a diagnostic procedure used to identify foods that an individual cannot consume without adverse effects.[1] Adverse effects may be due to food allergy, food intolerance, other physiological mechanisms (such as metabolic or toxins),[2] or a combination of these. Elimination diets typically involve entirely removing a suspected food from the diet for a period of time from two weeks to two months, and waiting to determine whether symptoms resolve during that time period. In rare cases, a health professional may wish to use an oligoantigenic diet to relieve a patient of symptoms…
