What You'll Learn
Caffeine increases muscle contractions
While drinking coffee will not cause physical injury, it can lead to back aches and exacerbate pre-existing pains. Caffeine places stress on the adrenal glands, which sit on top of each kidney at the back of the body. This weakens the glands and the surrounding area, including the lower back. Caffeine can also cause muscles in the body to become more tense and can affect sleep patterns, potentially leading to insomnia.
Caffeine has been shown to increase muscle contractions and reduce maximal displacement. A study on professional athletes found that a dose of 9 mg/kg of caffeine led to a significant reduction in contraction time and maximal displacement. Another study found that caffeine ingestion increased maximum voluntary torque (MVT) and voluntary activation of the quadriceps during isometric, concentric, and eccentric contractions. This suggests that caffeine ingestion can induce an acute increase in voluntary activation, leading to increased strength regardless of the contraction mode.
In vitro studies have also demonstrated that caffeine can increase muscular fiber excitability induced by a single electrical stimulus. However, it is unclear if the physiological level of caffeine reached after supplementation is sufficient to induce significant changes in the rate of muscle fiber contraction in vivo. The effect of caffeine on maximal voluntary contraction (MVC) strength is also unclear, with conflicting results from different studies.
The muscle contraction time after caffeine intake is faster after 30 minutes than after 60 minutes. This indicates that the time elapsed since caffeine ingestion influences muscle contraction time and delay time. Tensiomyography (TMG) has been used to assess muscle responses following caffeine administration and has proven to be an effective non-invasive method.
While the specific mechanism is still being studied, caffeine's ability to improve sports performance and cognitive function is well-known. Its blockade of adenosine receptors contributes to increased alertness and possible increased muscle fiber recruitment. Additionally, caffeine's inhibition of phosphodiesterase may result in increased muscle contractions.

Coffee's diuretic effects cause dehydration and muscle aches
Coffee is a diuretic, which means it increases the body's production of urine. This can lead to dehydration, which is a common cause of muscle aches and pains.
Caffeine, the main active ingredient in coffee, is a well-known stimulant that can induce muscle contractions. It is able to increase muscle fibre sensitivity and cause muscle tension, which can lead to muscle aches and pains. This is particularly true if you are consuming large amounts of caffeine over a short period of time, which can be easily done with coffee.
Caffeine can also affect your sleep patterns, making it harder to fall asleep and causing insomnia. Poor sleep can lead to muscle aches and pains, as the body is not able to recover properly.
In addition, caffeine places stress on the adrenal glands, which sit on top of the kidneys at the back of the body. This can weaken the area around the adrenal glands, including the lower back, and can also affect the joints, leading to back pain and muscle aches.
If you are experiencing muscle aches and pains and are a heavy coffee drinker, it may be beneficial to cut back on your coffee consumption. Reducing caffeine intake can help lower muscle tension and improve sleep, which can alleviate muscle aches and pains.

Coffee affects sleep patterns, impacting recovery from pain
Coffee is known to affect sleep patterns, which can have a knock-on effect on recovery from pain. Caffeine is the world's most widely consumed drug, and its stimulant properties are well-known. However, the specific impact on muscle aches is less clear.
Caffeine has been shown to induce muscle contraction and increase muscle fibre sensitivity. It can cause muscle tension, leading to back pain and spasms. This is due to its diuretic nature, which can lead to dehydration and subsequent muscle aches, particularly in the back. This is supported by several personal accounts of reduced muscle pain after cutting down on coffee.
The impact of caffeine on muscle aches is not limited to physical causes. Caffeine can affect anxiety and stress levels, which can also contribute to muscle pain and tension. Additionally, caffeine can disrupt sleep patterns, leading to insomnia and poor recovery from pain. This disruption to the body's metabolic rhythm can result in a vicious cycle of fatigue and increased caffeine consumption, further exacerbating the issue.
While the exact mechanism is not fully understood, it is clear that caffeine can negatively impact recovery from pain by affecting sleep and increasing muscle tension. The recommended caffeine intake is up to 400 milligrams (mg) or around four cups of coffee per day for healthy adults. However, this limit may need to be lower for those experiencing muscle pain or sleep issues.
In summary, while coffee may not be the direct cause of muscle aches, its impact on sleep patterns and muscle tension can hinder the recovery process. Reducing caffeine intake and opting for lower-caffeine alternatives can be beneficial for managing muscle pain and improving sleep quality.

Coffee stresses the adrenal glands, causing lower back pain
While coffee does not cause physical injury, it can lead to backaches and intensify pre-existing pains. The caffeine in coffee stimulates the adrenal glands, which are disc-shaped organs located above the kidneys in the lower back region. Consuming caffeine repeatedly stresses the adrenal glands, leading to their weakening over time. This, in turn, affects the surrounding areas, including the lower back, causing pain.
The adrenal glands, when weakened, also take away vital nutrients from the ligaments and tendons, which can then affect the joints. This includes the sacroiliac joint in the lower back, which supports the entire body's weight. As the body focuses on repairing the adrenal glands, the ligaments and joints in the lower back are neglected, leading to soreness and pain.
In addition to causing lower back pain, caffeine also has other negative impacts on the body. It increases muscle tension, leading to muscle knots and contractions, which can result in spasms and soreness. Caffeine can also disrupt sleep patterns, potentially causing insomnia and further contributing to pain and discomfort.
To determine if caffeine is the cause of back pain, it is recommended to reduce or eliminate caffeine intake. Lowering caffeine consumption can decrease pain and stress levels in the body. Switching to tea or other beverages with lower caffeine content can be a positive step towards improving overall wellness.
While the relationship between caffeine and muscle aches is not fully understood, there is anecdotal evidence suggesting a connection. Some individuals have reported experiencing muscle soreness and back pain after consuming coffee or other caffeinated drinks. Reducing caffeine intake has helped alleviate these issues for some people.

High caffeine consumers may experience muscle cramps
A case study published in The American Journal of Medicine reported that a 54-year-old man experienced muscle cramps in his calves and feet, as well as recurrent shoulder pain. The patient consumed approximately 600 mg of caffeine per day, and upon switching to a paracetamol-only compound, his muscle cramps disappeared.
Another study on professional athletes who regularly consume high amounts of caffeine found that a single dose of 9 mg/kg of caffeine significantly improved contraction time and reduced maximal displacement. While the exact mechanism of muscle cramping is still debated, it is hypothesized that caffeine may act synergistically with other factors to lower the threshold for inducing muscle cramps.
The effects of caffeine on muscle aches can vary between individuals, and other factors such as sleep patterns, anxiety, and overall health should also be considered. However, reducing caffeine intake or switching to lower-caffeine alternatives can be a strategy to alleviate muscle-related issues for those who are sensitive to its effects.
It is important to note that while caffeine may contribute to muscle aches and cramps, it is not the sole cause, and other factors such as pre-existing conditions, exercise habits, and overall lifestyle should also be taken into account when addressing muscle-related issues.
