You may dread the end of summer, but the drop in temperature could help you burn more fat while working out, according to one researcher.

Scientists already knew that the higher your body's SLN function, the lower your risk of obesity. They also knew that SLN was activated by exercise. Periasam and his team delved deeper, and found that cold temperatures also activate your body's SLN. He reasons that exercising in the cold could maximize your SLN function - and in turn, maximize your fat burn.

"You can double the amount of energy burned, so you burn more fat," Periasam explained to

How does this work, exactly?

Nearly all the cells in our body contain structures called mitochondria, which burn fat and create the energy we need to go about our days. The more we exercise, the more mitochondria our bodies produce.

Periasam found that SLN forces our mitochondria to work harder, and in turn, burn more fat. He also found that SLN creates even more mitochondria - and the more of 'em we have, the more fat we burn. Finally, he found that cold weather activates our SLN. Put it all together, and his conclusion is that exercising in cold weather could lead to greater fat burn.

It's worth noting that Periasam's research involved experiments on mice, not humans. But the scientist still believes that staying shut inside all winter long could put a dent in your SLN levels.

"The bad news is that people avoid cold. They're doing a disservice to themselves," he said.

To boost your SLN levels, Periasam stays you should "stay outdoors." (But use your judgment, guys: Don't push yourself to stay out if you're way too cold.)

Of course, getting out of bed for a chilly morning run doesn't sound appealing. But if you're determined, these four cold weather workout strategies could make the experience bearable.
