Check the side effects"},"content":{"rendered":"

If you\u2019ve ever bragged about \u201crunning on four hours of sleep,\u201d here\u2019s a wake-up call. Dr Sudhir Kumar, a neurologist at Apollo Hospitals<\/a>, shared on X that even one night of severe sleep deprivation<\/a> can mess with your brain almost as much as mild alcohol intoxication. From slower reflexes to forgetfulness, the damage kicks in faster than you\u2019d think \u2014 and it\u2019s all backed by science.Short term memory
According to Dr Kumar, sleeping less than four hours can significantly impact short-term memory. The parts of your brain that handle reasoning, decision-making, and recalling information \u2014 the prefrontal cortex and hippocampus \u2014 become sluggish. You might find it harder to follow conversations, remember new details, or even recall what you learned earlier in the day.
Attention span
Your attention span also takes a major hit. Lack of sleep triggers \u201cmicrosleeps\u201d \u2014 brief, uncontrollable lapses in focus that last just a few seconds but can have serious consequences. Reaction times slow down, multitasking becomes harder, and you\u2019re more likely to make impulsive decisions or errors.

Driving after sleepless night
Dr Kumar also warned about the dangers of driving after a sleepless night. Research shows that operating a vehicle with less than four hours of rest is comparable to driving with a blood alcohol level of 0.08% \u2014 the legal limit for drunk driving in many countries. Sleep-deprived drivers are more prone to drifting between lanes, missing signals, or braking too late, often with no memory of the lapse due to microsleeps.<\/p>\n

In short, even one night of poor sleep can throw your brain off balance \u2014 affecting memory, focus, and coordination just like alcohol would. If you\u2019ve slept less than four hours, Dr Kumar advises avoiding driving or handling anything that needs sharp attention. Your brain, quite literally, isn\u2019t in its best shape.<\/p>\n
