Biohacking is the latest wellness trend taking the internet by storm, with TikTok witnessing a staggering 316 per cent increase in searches. More notably, Bryan Johnson, the founder of KernelCo and Blueprint, has contributed to the intrigue after investing approximately $2 million per year to reduce his biological age. The 46-year-old tech tycoon recently made headlines for tracking his nighttime erections, in an attempt to reach the level of an 18-year-old. How exactly does he do that, you may ask? Well... He gives himself electric shocks in his private area. Johnson told Steven Bartlett on The Diary of a CEO podcast that nighttime erections "are actually a meaningful health indicator" because they "represent psychological health, cardiological health." While that's one extreme measure of biohacking, there are other methods behind the trend. A spokesperson for Snusboss said: "Biohacking refers to the practice of making changes to one’s biology, typically through self-experimentation and the use of technology, to enhance physical and cognitive abilities, optimize health, and achieve personal goals." “Currently #biohacking has 791 million views on TikTok, and continues to gain popularity, particularly with Millennials and Generation Z who are becoming more interested in the scientific research behind their health and wellbeing and are also open to experimenting with new techniques," he continued. Biohacking is essentially an unconventional experimental biotechnology that is believed to help improve overwell wellbeing. Here are several ways people are implementing into their lives: Ice cold plunge "Cold plunging is an aspect of cold-water therapy or cold-water immersion, which involves immersing oneself in cold water temperatures. "It is recommended to complete 11 minutes of cold-water exposure per week, which can be broken into three minutes per session. "Studies suggest 50 to 59 degrees Fahrenheit (10 to 15 degrees Celsius) to be an optimal temperature range for cold plunges focused on reducing muscle soreness. "Doing this will also help to reduce inflammation, improve circulation, and enhance recovery after exercise. It is also shown to boost the immune system, improve sleep quality and help with stress management." Optimise your sleep "If you are getting around seven to nine hours of sleep a night, you will encourage muscle growth and repair, help keep your brain alert, improve your blood sugar levels and even enhance your lifespan. "Whilst there are several tips on social media such as eating certain fruits before bed, avoiding electronic devices and avoiding alcohol, one of the most important rules of optimizing sleep is maintaining a good circadian rhythm. "This means going to bed and waking up at the same time every day, even on weekends. To do so, try maintaining a routine and try to spend time outdoors during daylight, especially in the morning. This is because natural light exposure helps regulate your body's internal clock and promotes alertness during the day. "To measure progress, you can use devices such as smartwatches that track sleep duration and quality." Regular saunas "Saunas, small rooms heated with hot air or steam, are said to have cardiovascular health benefits. "When exposed to high temperatures, the body then works to cool itself down by increasing heart rate, blood flow, and cardiac output. This is known to decrease blood pressure, leading to benefits for cardiovascular health and longevity. "For best results from this biohack, choose a temperature between 175-195F (80-90C) with 10-20 per cent humidity for 30 minutes at least three times a week." Himalayan salt in water "Electrolyte levels are important for the body to function properly. They help to balance the amount of water in your body, balance your acid/base (pH) levels and move nutrients into your cells. "Your body makes electrolytes naturally, as well as obtaining them from food, drinks and supplements. "However, if your levels drop, mineral-rich Himalayan salt contains lots of electrolytes and is proven to help detox the body, supporting kidney and liver functions. "Therefore, around one teaspoon of Himalayan salt added to one litre of water is recommended per day. "Not only will it keep you feeling energised, but also help to boost your metabolism." Moderate coffee intake "Low to moderate doses of caffeine (50–300 mg) are scientifically proven to cause increased alertness, energy, and ability to concentrate. "Science also suggests drinking two cups of coffee a day could help ward off heart failure when a weakened heart has difficulty pumping enough blood to the body. "Both regular and decaf coffee have a protective effect on the liver. Research shows that coffee drinkers are more likely to have liver enzyme levels within a healthy range than people who don’t drink coffee. "Experts say it is healthy to drink a maximum of 2.5 cups of coffee per day." Breathwork "We breathe every single day, but we often don’t even think about how we are breathing. "In times of stress, our breath automatically responds by shortening and speeding up and this can cause further strain on the body. "With breathwork practice, the body can be trained to automatically control breathing and utilize it as a calming tool during times of stress. "Breathing also directly affects how much oxygen our cells are getting, so when we deepen and slow down the breath from its usual pattern, we allow more oxygen to enter each cell. "To practice breathwork, inhale for 4 seconds and exhale for 6 seconds. Repeat this for around 10 minutes per session. For best results, do this once in the morning and once in the evening." Red Light Therapy (RLT) "Red light therapy (RLT) is a popular method used to optimize overall skin health. RLT also helps to boost muscle recovery, reduce pain and inflammation, support nervous system health, and generally increase energy levels. "For those who experience inflammation and pain with Achilles tendinitis, and have signs of skin ageing and skin damage, research shows RLT may smooth your skin and help with wrinkles. RLT is also known to help with acne scars, burns, and signs of UV sun damage. "To complete the treatment, lie in a full-body LED red light bed or pod or be treated by a professional with a device that's outfitted with panels of red lights. "Professionals recommend trying red light therapy three times per week for 10 minutes each time for a minimum of one month."
