Making time for regular exercise can make your eyes feel better. A team led by researchers from the University of Waterloo discovered that a significant increase in tear secretion and tear film stability after participating in aerobic exercise can be another remedy for relieving dry, itchy eyes.

Every time we blink, our eyes are covered in tear film — an essential protective coating necessary for maintaining healthy ocular function. Healthy tear film comprises three layers-oil, water, and mucin-that work together to hydrate the ocular surface and protect against infection-causing irritants like dust or dirt.

When any part of the tear film becomes unstable, the ocular surface can develop dry spots, causing eye symptoms like itchiness or stinging and burning sensations.

A new study from Trinity College Dublin highlights that fitness may be a more important clinical endpoint for improvement in patients with fatty liver diseases during exercise trials, rather than weight loss. The findings have been published today (Tuesday, 28th July 2020) in the medical journal Alimentary Pharmacology and Therapeutics.

Metabolic associated fatty liver disease (MAFLD) is a condition characterised by a build up of fat in the liver. The liver is central to a suite of vital processes in the body including digestion, blood clotting and energy production.

If left untreated, MAFLD can lead to serious complications like liver fibrosis (scarring), cirrhosis, liver failure and liver cancer, as well as cardiovascular and metabolic issues...

High-intensity interval training triggers endorphin release in the brain. Photo: Turku PET Centre

Finnish researchers at the University of Turku have revealed that exercise-induced endorphin release in the brain depends on the intensity of the exercise. Endorphin release induced by exercise may be an important mechanism which affects exercise motivation and maintenance of regular physical activity. The popular high-intensity interval training (HIIT) leads to endorphin release in the brain, which might alleviate the physical and emotional stress caused by the high-intensity exercise. A less demanding, traditional one-hour aerobic exercise does not cause similar endorphin release.

In the study, HIIT significantly increased the release of endorphins and other opioid peptides in the brain area...

Aerobic exercise preserves brain volume and improves cognitive function

Using a new MRI technique, researchers found adults with mild cognitive impairment (MCI) who exercised 4 times a week over a 6-month period experienced an increase in brain volume in specific, or local, areas of the brain, but adults who participated in aerobic exercise experienced greater gains than those who just stretched. The study included 35 adults with MCI participating in a randomized, controlled trial of exercise intervention. Individuals with MCI are at risk of developing Alzheimer’s disease (AD) which affects >5 million Americans today.

The participants were divided into two groups...
