In the Heat, Ice Really Is Nicer to Your Body
When you’re exercising in warm weather, it’s both the amount of water you drink and its temperature that are important. University of Montana scientists monitored people walking briskly on a treadmill in 31°C heat. During the three-hour test, they alternately refreshed themselves with ice water slurries or lukewarm water. Exercisers had to drink twice as much warm water as ice water to maintain a healthy heart rate, core body temperature and skin temperature.
Yellow Light on Red Yeast Rice
Because red yeast rice (RYR) contains monacolin K, a compound chemically identical to the active ingredient in the cholesterol drug lovastatin, it has become a popular dietary supplement, taken in pill form. The good news: RYR may lower cholesterol. The bad news: an Italian survey has found that RYR carries some of the same risks as statins, namely muscle and liver damage. And while a patient with a lovastatin prescription will be under a doctor’s care, RYR is usually self-prescribed. Before using RYR to combat high cholesterol, talk to your doctor and ask him or her to supervise you.
Home Massages: To Give Is to Receive
Some things are best left to the pros, but the DIY version of a relaxation massage works well, according to a study from Northumbria University in the UK. Healthy but frazzled couples took a three-week course to learn simple massage techniques. Their perceived stress levels diminished as they used their new skills. What’s more, both the partner who received the massage and the one who provided it got a wellness boost across eight domains, including energy, pain and mood.
