Like kayaking or canoeing, paddleboarding provides a serious workout. But before you head out on the water, you'll want to get some key muscle groups in shape, especially ones that probably have not been used much during winter.

A 2022 study examined the brains of older adults after they died, and found that those who had stayed the most active late in life had higher amounts of synaptic proteins. These proteins improve the connections between the brain’s nerve cells.

It's difficult to get motivated to be active outside during cold-weather months, but it's important to your health and can help you meet any fitness goals you're trying to reach. There are ways to get outside and moving in cold temperatures.

Exercising is crucial for good health, even if exercising doesn't help a person get down to a healthy weight. Exercising reduces the risk of high blood pressure, high cholesterol, high blood sugar levels, heart disease, stroke, diabetes, Alzheimer's disease, and premature death. If someone is overweight and unfit, the risk of premature death is double the risk of someone who is the same age and sex, and is overweight but fit.

A study published online Aug. 20, 2021, by Nature Metabolism suggests that the hormone irisin, produced during exercise, might have something to do with the beneficial effects of exercise on the brain. Scientists suspect that irisin plays a role protecting the brain against changes characteristic of Alzheimer's disease, possibly by reducing brain inflammation. Irisin has also been shown to turn white fat cells (which store fat) into brown fat cells (which burn fat), and also to improve insulin resistance. Such changes reduce body weight and protect against both diabetes and heart disease.
