In the age of information overload, it's amusing how we often cling to outdated health myths and folklore as if they were gospel. Many of us blindly follow what our ancestors did, believing that if it worked for them, it must be the best way. But let's take a closer look at some of these seemingly timeless health 'rules' and uncover the truth behind them.
Feed a Cold, Starve a Fever
This age-old advice, dating back to Hippocrates, suggests that feeding someone with a cold will help them recover, while starving someone with a fever will cure them. However, this is simply not true. A fever is a symptom, not a disease, and treating both a cold and a fever involves hydration, nutrition, and rest. The myth likely originated from the idea that a fever is a disease that needs to be starved to be cured, but this is far from accurate.
Walking 10,000 Steps a Day
The ubiquitous 10,000-step goal has become a global phenomenon, thanks to a Japanese pedometer called Manpo-kei. But is it really the magic number for our health? A 2019 study by Dr. I-Min Lee found that just 7,500 steps a day can significantly reduce the mortality rate. While 10,000 steps might not be for everyone, the key is to be more active, not necessarily to hit a specific number. As Simon Ngo, director of Pilates and yoga at Flow Athletic, points out, the human brain loves whole numbers, but the focus should be on being active, not on the number itself.
Eight Glasses of Water
The ubiquitous 'eight glasses of water a day' guideline is more myth than science. Hydration needs vary depending on individual factors like weather, diet, activity level, age, and body size. While plain water is best, it's not the only source of hydration. Eating fruits and vegetables like watermelon, berries, oranges, cucumber, and tomatoes can also contribute to your fluid intake. Caffeinated drinks like tea, coffee, and alcohol should be consumed in moderation as they can increase water loss.
Breakfast is the Most Important Meal of the Day
This phrase has a fascinating history, rooted in religious moralisation, fear of indigestion, and advertising. While it's a marketing slogan, there's some truth to it. Breakfast can help regulate blood sugar, insulin sensitivity, stress response, and energy levels. However, the type of breakfast matters. A solid breakfast with 25-35g of protein within an hour of waking can set you up for the day. Foods like eggs, Greek yoghurt, or a smoothie with fat and fibre can keep blood sugar steady and prevent morning cortisol spikes.
Cold Weather Causes a Cold
It's a common misconception that cold weather directly causes colds. While symptoms like a tingling nose and dry throat can make you feel cold, they are not the cause of the cold. The immune system's response to the cold virus, releasing pyrogens to raise body temperature, is what makes you feel cold. The real culprit behind the increase in colds during winter is the closer proximity of people indoors, making it easier for viruses to spread.
In conclusion, many of our health 'rules' are just myths. It's essential to look beyond folklore and listen to our bodies, adapting our habits to suit our individual needs. After all, health is a complex and personal journey, and what works for one person may not work for another.
