High-intensity interval training (HIIT) effective at improving metabolic health, particularly in those at risk of or with type-2 diabetes.

Short bursts of vigorous exercise may be a more time efficient training method for lowering blood sugar levels and preventing and managing Type 2 diabetes when compared to continuous moderate-intensity exercise researchers at the University of Leicester have found.

The study involved a meta-analysis of fifty experimental articles allowing researchers to pull together information and establish a foundation for their conclusions.

Participants at risk for or with Type 2 diabetes performing HIIT experienced a greater reduction in fasting glucose levels compared to participants performing continuous moderate-intensity exercise.

HIIT may be suitable as an alternative to continuous moderate-intensity exercise when time is limited and may promote lower blood sugar levels and increased metabolic health, particularly in those with Type 2 diabetes.

Larger randomized controlled studies of longer duration are warranted to add confirmation to these results.

How healthy you rate yourself may predict the likelihood of catching a cold.

Results published in the journal Psychosomatic Medicine may indicate that subjects who rated their health below the top-level of "excellent" were associated with weakened immune system competence. 

Researchers at Carnegie Mellon University and the University of Pittsburgh School of Medicine analyzed data from 360 healthy adults aged 18‒55 years. Study participants associated with regular smoking, heavy drinking, less exercise, poor sleep, and a greater body mass index were twice as likely to catch a common cold compared to those who rated their health as "excellent".

Maintaining a healthy lifestyle consisting of proper exercise and sleep could decrease the chance of setbacks associated with catching a cold.
