Captain America is a superhero with a range of impressive powers, including super-strength, enhanced intelligence, and immunity to toxins and diseases. But does he ever sleep? In the Marvel films, it is never explicitly stated that Captain America doesn't need to sleep, and it is likely that he does, at least occasionally. However, his super-soldier serum gives him an incredibly fast metabolism and the ability to destroy fatigue-inducing toxins, meaning he probably only needs a few hours of sleep a week.

What You'll Learn
Captain America's superpowers include immunity to fatigue
Captain America's endurance is also linked to his enhanced willpower and strength, which exceed that of normal humans. His body has an effectively limitless energy output, and he only needs an hour or two of sleep per week to recharge. This is because the Super Soldier Serum he was injected with helps to break down the chemicals that lead to muscle exhaustion.
Captain America's endurance is further enhanced by his high metabolic rate, which constantly regenerates the Super Soldier Serum in his body. This means that he needs to consume a large amount of food and water to maintain his energy levels. However, his body perfectly processes whatever he eats, so he won't wear out.
Captain America's immunity to fatigue also contributes to his enhanced intelligence. His enhanced brain function allows him to make lightning-fast calculations and life-saving decisions in a fraction of a second. This makes him one of the greatest battle tacticians on the planet.

He likely needs less sleep than the average person
Captain America, or Steve Rogers, likely needs less sleep than the average person. This is due to the Super Soldier Serum, which keeps his superhuman body from getting tired and worn out. The Serum helps Captain America's body destroy fatigue-inducing toxins that are prevalent in all humans, and as a result, he can keep going and going while his enemies eventually tire out.
Captain America's endurance is further enhanced by his ability to recover more quickly from fatigue than normal people. This is likely due to his enhanced metabolism, which burns four times faster than the average person. This means that while his body might not require as much sleep, his mind likely would. From a psychological standpoint, it is reasonable to assume that he would need sleep to help cope with the stresses of his lifestyle.
Captain America's enhanced endurance is also reflected in his ability to go for long periods without eating or drinking. His body can perfectly process whatever he eats, and he does not 'run out of gas' just because his metabolism is higher. This is similar to the endurance of a top-of-the-line human, such as a Navy Seal, who can put their body through extreme conditions.
Captain America's endurance and reduced need for sleep give him more time for activities such as training, which explains his exceptional skill in martial arts and hand-to-hand combat. He is dedicated to the cause and eager to please, so he trains rigorously despite not needing to.

His body is effectively limitless in energy output
Captain America's body is effectively limitless in energy output. This is due to the Super Soldier Serum, which immediately breaks down the chemicals that lead to muscle exhaustion. As long as he gets enough food and water, he won't wear out. His body perfectly processes whatever he eats, and he has an insanely fast metabolism. This means he needs to eat a lot, even more than an average human athlete, but his body never runs out of gas.
Captain America's endurance is far beyond that of a normal human. He can go for days and days without sleep, and then get a few hours. On any given night, he's more likely to be awake than asleep. If he is on a mission, his periods of wakefulness can stretch into weeks without rest. He can exert himself for multiple hours without getting winded, and his ability to recover from fatigue is far superior to that of a normal person.
Captain America's body can destroy fatigue-inducing toxins, which are prevalent in all humans. This means he can keep going and going while his enemies eventually tire out. He can use his physical dominance over others to his advantage for hours at a time, pummeling anyone who dares to face him.
Captain America's body is like a low-level healing factor. While not fast enough to be considered a superpower, bruises won't last longer than a day, and cuts heal within 24 hours. Broken bones can heal in a day, and bullet or knife wounds in hours. Captain America has an immunity to all Earthly diseases and cannot be killed by toxins or poisonous gases.

He needs more food than the average person
Captain America's body is immune to fatigue, thanks to the Super Soldier Serum. This serum helps his body destroy fatigue-inducing toxins, allowing him to exert himself for multiple hours without getting tired. As a result, Captain America only needs about an hour or two of sleep per week.
However, this accelerated metabolic rate means that Captain America needs to consume a lot more food than the average person. In fact, his caloric intake needs to be massive. His body is constantly regenerating the Super Soldier Serum, which requires a constant supply of nutrients.
Captain America's enhanced physical abilities and accelerated metabolism mean that he needs to consume a large amount of food to sustain himself. His body can perfectly process whatever he eats, but he needs a constant supply of food and water to survive. This is because his body is in a constant state of high energy output and requires a lot of fuel to function optimally.
Captain America's diet likely consists of a large volume of nutrient-dense foods. He probably consumes a lot of protein to support his muscle growth and recovery, as well as complex carbohydrates for sustained energy. Healthy fats are also an important part of his diet, providing essential fatty acids that contribute to overall health and energy levels.
Overall, Captain America's dietary needs are far greater than those of an average person due to his accelerated metabolism and enhanced physical abilities. His body's efficient processing of nutrients and constant regeneration of the Super Soldier Serum contribute to his increased food intake requirements.

He has enhanced intelligence
Captain America's enhanced intelligence is one of his most underrated superpowers. Steve Rogers' brain was also upscaled when he became a Super Soldier, and every part of his brain was enhanced when he became Captain America.
Captain America's enhanced intelligence allows him to complete lightning-fast calculations and make life-saving decisions in a fraction of a second. His intelligence is perhaps his most underrated superpower. If he wasn't super-strong and tough, most people would be talking about his ability to analyze threats and quickly change courses when dealing with danger in real-time.
On top of all this, Captain America also has a perfect memory, which is great for military tactics such as speaking multiple languages, espionage skills, and enhanced reasoning. He can really do it all, which is why he's considered one of the greatest battle tacticians on the planet. There may be other superheroes in the Marvel Universe who can beat him in a fight, but when it comes to planning and adapting, Captain America can work faster than a computer to change an outcome immediately and end up with the upper hand.
Captain America's enhanced intelligence is a result of the Super Soldier Serum, which he was injected with when he became Captain America. The Serum helps Captain America's body destroy fatigue-inducing toxins that are prevalent in all humans, and as a result, he can keep going and going while his enemies eventually tire out. Without fatigue, Captain America can use his physical dominance over others as an advantage, and he can do it for hours at a time, absolutely pummeling anyone who dares to face him.
