Can You Reverse Aging By Injecting 'Young Blood'? No, But People Are Trying It

Like many celebrities and entrepreneurs, 45-year-old US tech billionaire Bryan Johnson is trying to reverse the ageing process.Spending an average of US$2 million a year on an anti-ageing regimen, Johnson claims he now ages slower than some children. He explains,“The pace my body accumulates ageing damage is less than the average ten-year-old.”Many of Johnson’s age-reversal methods are questionable, involve dodgy science, and have known side effects.While you can’t stop the ageing process, and the gradual decline our bodies experience as we advance in years, there are some things we can all do – for free – to maintain our health as we age.FastingJohnson reports fasting for 23 hours a day. He then eats one meal a day: 2,250 calories of nutrient-dense food “customised” to his body’s needs.6 Natural Anti Aging Tips to Slow Down Skin Aging ProcessEating for time-restricted periods in the day can have a positive effect on how we metabolise nutrients, inflammation levels, hormonal regulation, and cardiometabolic health (blood sugar, triglycerides, cholesterol, blood pressure, BMI, and waist circumference).However, a Spartan-like food intake can impair how our body responds to sugar (known as glucose tolerance). And it’s not necessarily any more effective for weight maintenance than reducing calorie intake at each meal.Large-scale, long-term human trials are needed to confirm the limited risk-benefit findings of fasting.Acid PeelsJohnson has weekly acid peels (which use a mild acid to exfoliate the skin) to maintain a “youthful glow”.But you cannot smoothen sagging facial skin or remove deep scars or wrinkles. Acid peels also come with risks, including organ damage, infection, scarring, and swelling.Plasma InfusionsPerhaps the most bizarre youth-inducing procedure Johnson has attempted is receiving blood transfusions from his 17-year-old son.US biotech companies have explored plasma infusions to tackle age-related diseases in humans for decades. But there are no proven clinical benefits.Side effects from blood transfusions include blood-borne infections, fever, and allergic reactions.Humans have been experimenting with anti-ageing methods for centuries. These have included all sorts of behavioural and lifestyle practices that are quirky, questionable, and even sadistic.Ancient practices included crocodile dung face masks, which the Greeks and Romans used to brighten their complexions.Romans also used donkey milk and swan fat, to minimise wrinkles, due to their acclaimed rejuvenating properties.Cleopatra apparently took daily baths in sour donkey milk. To sustain this lavish habit, she had a herd of 700 donkeys. Sour milk contains lactic acid, a naturally occurring alpha-hydroxy acid (AHA) that exists in many modern-day exfoliants. So this idea was grounded in basic science, at least.During the 16th and 17th century, “Countess Dracula” aka Elizabeth Bathory allegedly resorted to serial killing to quench her thirst for youthfulness, bathing in the blood of her young victims.Fountains of youth fixations have inspired many contemporary anti-ageing trends. Exposure to cold is a firm favourite.Some research suggests this could have benefits relating to longevity, by slowing cellular degeneration, stimulating collagen, and elastin production, increasing the metabolism, and reducing inflammation.Dutch motivational speaker Wim Hof includes cold water immersion as one of the three pillars of his Wim Hof Method to “increase mind-body connection.”Athletes such as Cristiano Ronaldo use cryotherapy, exposing their bodies to extremely cold temperatures for 2-4 minutes to decrease the signs of ageing and enhance their general health.However, the risks of cryotherapy include bone fractures, frostbite, nerve damage, bleeding, cramping, swelling, and skin infections.Two of the more mainstream anti-ageing methods that Johnson recommends are the daily self-care habits of sleep and exercise.He has a strict sleep schedule that involves retiring to bed at 8 pm, with a one-hour wind-down in a darkened room.Adults report poorer sleep quality and difficulty being able to sleep for long as they age. Sleeping too much or too little is associated with a greater risk of obesity, heart disease, and premature death.Diet for Skin: Anti-Aging Foods For Younger Looking Skin Developing a regular sleep routine, reducing bedroom distractions such as mobile phones, and exercising regularly can all help to alleviate sleep problems.Exercise, often cited as a wonder drug for healthy ageing, is something Johnson takes very seriously. He does a “blueprint” workout that includes specially designed daily techniques as well as high-intensity interval training sessions, hiking, and playing sport.From middle age onwards, we all need to exercise regularly - to increase our muscle mass, bone density, strength, endurance, coordination, and balance. One of the greatest health risks for older people is falling, which balance, flexibility, endurance, and strength training can help reduce. Physical activity can bring social benefits in older adults if undertaken in groups, and there are well-known mental health gains.Small changes in sleep, diet (eating plenty of vegetables, fruit, wholegrains, healthy fats, and enough protein), and exercise can support healthy ageing, reducing the chance of early death, and helping us all to lead an active and independent life in our senior years. Now that is something worth investing in!(Rachael Jefferson-Buchanan is a Lecturer in Human Movement Studies (Health and PE) and Creative Arts, at Charles Sturt University This article was originally published at The Conversation.
