The Science of Switch On

Resilient Nutrition

THE RATIONALE BEHIND SWITCH ON A huge number of us don’t look, feel or perform our best because we don’t routinely sleep well. There are many forms of sleep problems. Some sleep issues are common, such as recurrent sleep restriction (not getting as much sleep as needed) and “social jetlag” (shifting sleep times between workdays and work-free days). Other sleep problems are more debilitating, however, and these include 6 broad categories of sleep disorders (insomnia, circadian rhythm sleep-wake disorders, sleep-related breathing disorders, sleep-related movement disorders, parasomnias, disorders of hypersomnolence). Perhaps unsurprisingly, some sleep problems have been exacerbated by COVID-19 lockdowns....

We should not take our good fortune for granted, however. The Ukraine War, climate change,...

Ginger: Health Benefits, Side Effects, and How to Take It

Greg Potter

It’s thought that people in India and China have used ginger therapeutically for at least 5,000 years, and ginger was probably used to spice up foods long before this. Over the years, interest in ginger has waxed and waned, with notable surges when Queen Elizabeth I reportedly invented the gingerbread man and now again in the 21st century as people turn to ginger shots and other spicy concoctions in the hope of garnering a range of health benefits. But is ginger a legitimate health booster, or is this all just spicy hype? Today we’ll look at what's known about the science of...
