A neurologist has outlined three common habits he personally avoids due to their potential to increase the risk of stroke. Dr Baibing Chen, a double board-certified neurologist, shared his insights in a TikTok video that has garnered over five million views.
Dr Chen's first habit to avoid is energy drinks. He explains that many energy drinks contain very high caffeine levels, often exceeding the recommended daily limit for adults, along with other stimulants like guarana and taurine. This combination can disrupt blood vessel regulation and increase the risk of dangerous heart rhythms, which may lead to clots that travel to the brain and cause a stroke. He also notes that excessive vitamin B in these drinks can cause nerve damage over time.
The second habit involves weightlifting. Dr Chen warns against performing a one-rep max or lifting heavy weights while holding the breath, a technique known as the Valsalva manoeuvre. This can spike systolic blood pressure to extreme levels, sometimes over 400, putting massive force on brain blood vessels and potentially triggering brain bleeds. He recommends safer strength-building methods with controlled breathing, exhaling during exertion, and using submaximal weights with higher reps.
Finally, Dr Chen cautions against certain yoga poses that force the neck into extreme hyperextension or hyperflexion. In rare cases, these can lead to a tear in the vessel wall, known as dissection, which can cause a stroke. He advises staying mindful of neck position and avoiding extreme strain during yoga.
