Do you ever feel like your morning coffee gives you the jitters? Have you ever wondered if that cup of joe is actually making you stiff? Well, you’re not alone! In this blog post, we’ll cover the science behind why coffee might be making us stiff and what we can do about it.

What is caffeine and how does it affects health

Caffeine is a stimulant found in many products, such as coffee, tea, cola, cocoa, guarana, yerba mate, and over 60 other products. It works by stimulating the central nervous system, heart, and muscles. However, consuming too much caffeine can have negative effects.


Caffeine and its impact on flexibility

Caffeine can have an adverse effect on flexibility, depending on how much is consumed and how the individual reacts to it. It is important to be aware of your body’s response when consuming caffeine and take appropriate measures to ensure that it does not negatively affect your flexibility. 

Caffeine and its impact on soft tissue injuries

Caffeine has been found to impact soft tissue injuries, particularly regarding wound healing and epithelialization. Studies have shown that caffeine can impede wound healing, inhibit collagen synthesis, and disturb the early stages of bone healing. 

People suffering from soft tissue injuries should be mindful of their caffeine intake and consider cutting back if they have difficulty healing or experiencing any adverse effects.

Caffeine and its impact on tendonitis

Caffeine is also linked to tendonitis, as it can increase muscle tension and impair sleep patterns. People with tendonitis often experience more pain and inflammation when they consume caffeine. 

Caffeine can cause low thyroid function

Low thyroid function, which is indicated by a basal resting temperature, is the third most common cause of joint pain related to coffee consumption. Studies have found that drinking coffee may not hinder the absorption rate of thyroid medications but can reduce it. 

Additionally, coffee increases blood sugar levels which can exhaust the adrenals and lead to thyroid problems. If you have an underactive thyroid, drinking coffee can worsen your fatigue and cause other symptoms. 

Effects of caffeine on adrenal glands

Caffeine can have a serious effect on your adrenal glands. Caffeine consumed in large amounts daily strains your adrenal glands as they overwork to make more cortisol. 

How caffeine affects adrenal glands

Caffeine has been found to impact the adrenal glands and can lead to an overstimulation of these essential organs. When consumed in high amounts, caffeine can cause the pituitary gland in the brain to perceive it as an emergency, stimulating the adrenal glands to release adrenaline. 

Effects of caffeine on stress levels

Caffeine increases cortisol secretion in people at rest or under mental stress. This means that if an individual consumes too much caffeine, they could put their body under additional stress, increasing cortisol. 

While the body naturally produces cortisol to help regulate stress levels, too much of it can lead to several unpleasant side effects. 

Common symptoms experienced with caffeine over-stimulation

Caffeine can have a range of effects on the body, and when consumed in large amounts, it can lead to overstimulation. Common symptoms experienced with caffeine over-stimulation include 


When it comes to the effects of caffeine on our health, one common issue is anxiety. Caffeine is a stimulant and can cause people to experience feelings of restlessness and nervousness. Excessive caffeine consumption (1 to 1.5 g/day) can lead to caffeine poisoning or caffeinism, which is characterized by symptoms such as anxiety. 

Caffeine raises your energy levels and blood pressure, making you anxious and on edge. If you are prone to anxiety or struggling with an anxiety disorder, it is important to be mindful of how much caffeine you consume to avoid overstimulation.

Muscle twitching and tremors

Muscle twitching and tremors are common symptoms experienced with caffeine over-stimulation. Too much caffeine can amp up the nervous system and lead to muscle twitching and cramps, causing stiffness and immobility. 

In addition, caffeine can also lead to chronic fatigue, stress, and insomnia, all of which can further contribute to muscle problems. Caffeine supplementation can improve muscle activation time in sports. 

Digestive issues

It is well-known that caffeine can have an adverse effect on digestion. Caffeine increases the amount of acid in your stomach and may cause heartburn or upset stomach. It can also stimulate gallbladder contraction and colonic motor activity, increasing the need for bathroom use. 

Managing caffeine intake for optimal health

Managing caffeine intake for optimal health is important for maintaining flexibility and reducing the risk of injuries. Studies have shown that when consumed in moderation (50-300 mg), caffeine can produce positive effects if you drink coffee, gradually reduce the number of cups per day and opt for decaffeinated or low-caffeine varieties.
