Can platelet-rich plasma injections heal your joints?

Platelet-rich plasma injections are used to reduce pain and speed healing for a number of common problems that affect the tendons, muscles, and joints, ranging from arthritis to shoulder pain. But a growing body of research shows that they may not be effective for some conditions, including knee osteoarthritis, ankle osteoarthritis, and Achilles tendinitis. There is some evidence that it may be effective for lateral epicondylitis (tennis elbow). People should consider whether there is a better option before undergoing PRP injections.

Hike your way to better health

Hiking is similar to walking but can be more challenging and can provide a nice change of pace. Walking over uneven terrain typically burns more calories than a walk on a flat surface. It also builds muscle strength and improves balance. A wilderness walk also brings mental health benefits. Choosing a path to a scenic destination may motivate people to go farther and climb higher and increase fitness gains.

Could a low-carb diet help your heart?

A 2021 study found that a low-carb diet may not necessarily be bad for heart health, despite its high saturated fat content. However, the study period was short, and the diet used in the trial was healthier than many low-carb approaches. More research is needed to confirm the results. In the meantime, experts recommend finding a sustainable diet that provides a healthy daily mix of nutritious foods instead of solely looking at carbohydrate content.

Dealing with dizziness

Many people experience dizziness, or a feeling of being woozy or lightheaded, from time to time. In most instances it’s triggered by a minor underlying problem, such as dehydration, a medication, or blood pressure fluctuations. Only rarely is dizziness caused by something more serious, such as a heart rhythm disturbance or stroke. However, even if dizziness isn’t caused by something serious, it can lead to a dangerous fall, so it’s important to prevent these episodes when possible. People should get emergency help for dizziness that is long-lasting, severe, or accompanied by other symptoms, such as difficulty walking or numbness.

Your brain on high blood pressure

High blood pressure not only can raise risk for a heart attack, but also can affect the brain. Keeping blood pressure normal can make brain injury from stroke less likely to happen and perhaps slow the natural decline in cognitive function. Just like with the heart, the best way to protect the brain from high blood pressure is to lower blood pressure if it’s high and keep it as close to a normal level as possible.
