Strength training can reduce the risk of injury for runners by improving muscle strength, endurance, and joint stability. Research supports its effectiveness in preventing common running-related injuries.

The recommendation to take 10,000 steps a day for good health is not strictly necessary and is more of a general guideline. Research suggests that while increasing physical activity is beneficial, the exact number of steps can vary based on individual health goals and conditions.

Walking after meals has been shown to improve blood sugar control, particularly for those with insulin resistance or diabetes. Light to moderate physical activity can enhance glucose uptake by muscles, reducing postprandial blood sugar spikes.

Cracking your knuckles is not harmful and does not cause arthritis, but it might lead to other minor issues over time. Most research indicates that it is generally safe, though some people may experience temporary discomfort or reduced grip strength.

Blue light blocking glasses may improve sleep quality for some individuals by reducing exposure to blue light, which can interfere with the production of melatonin, a sleep-inducing hormone. However, the effectiveness can vary depending on individual habits and the quality of the glasses used.

Eating more protein at breakfast can aid in weight loss by increasing satiety and reducing overall caloric intake throughout the day. This is supported by research indicating that a high-protein breakfast can help with appetite control and metabolism. However, individual results may vary based on diet and lifestyle.

Yes. Research consistently shows caffeine consumed 6 hours or less before bedtime reduces total sleep time, increases awakenings, and lowers sleep quality — even if you don’t “feel” the effects.

Cold exposure can help some people fall asleep faster by lowering core body temperature, but ice baths too close to bedtime may increase alertness and stress hormones.

Foam rolling can temporarily reduce muscle soreness and improve range of motion, but it does not significantly speed up physiological muscle recovery.

Creatine improves power, sprint ability, and muscle phosphate stores, but does not significantly improve long-distance running performance. It’s beneficial mainly for sprinting or hill repeats.

Drinking more water can slightly increase calorie burn and reduce appetite in some people, but it’s not a magic weight-loss solution. Its benefits are modest and depend on overall diet and behavior.
