Decrease your risk of heat stroke this Fourth of July

The upcoming Fourth of July holiday is usually grounds for lounging in the sun, hanging out with friends and family and enjoying a good barbecue. However, when the heat rises it’s important to protect yourself from heat and sun related illnesses such as heat stroke.

Research Snapshot: Obesity can lead to the alteration of specific genes

In a new study from the University of Minnesota, researchers found there are numerous areas of the genome where obese and non-obese individuals differ in terms of their “methylome.”

Essentially, the researchers found that the level of DNA methylation (addition or subtraction of a methyl group on the DNA molecule) was related to level of body mass index (BMI), a marker of obesity. These differences in methylome are a type of “epigenetic” variation, which does not involve the genetic sequence itself, but rather is thought to alter which genes are turned “on” and “off” at a given point in time in a given tissue. Typical genetic sequences do differ but data shows these differences go beyond that.

Be happy and lean; exercise green!

Exercise of any kind can be beneficial to our health and fitness, but exercise in nature, called ‘green exercise,’ can provide additional physical and mental health benefits. As we swarm the treadmills at the local gym, perhaps we should consider hitting the trails, the park or the lake, too.

“When you go outside, you have a more rich, holistic benefit to your exercise routine,” said Jean Larson, Ph.D., director of nature-based therapies at the University of Minnesota’s Center for Spirituality & Healing and the Minnesota Landscape Arboretum. “Green and traditional exercises are both beneficial, but there is a bump in the satisfaction and overall impact of the experience when you go outside.”
