Clenching your fists is a common physical reaction to emotions such as anger, frustration, or stress. It is often associated with increased willpower and self-control, as demonstrated in various experiments. Clenched fist or psycho-flexed hand syndrome, first described in the 1980s, is a condition that has been observed in patients with psychiatric disorders and physical trauma. While the exact causes are not fully understood, psychological factors are believed to play a significant role. In this response, we will explore the muscles involved in clenching fists, the potential benefits, and the conditions associated with involuntary fist clenching.

What You'll Learn
Clenching fists may increase willpower
According to research, clenching your fists may help increase your willpower. The mind and body are closely connected, and clenching your muscles can activate your willpower. This phenomenon is known as embodied cognition, where bodily actions resulting from an exertion of willpower can serve as a source to recruit willpower and facilitate self-control.
Experiments and Findings
Researchers Hung and Labroo conducted a series of experiments to understand the relationship between muscle tightening and willpower. In one experiment, participants decided whether to donate to a Haiti relief effort. Those who gripped a pen tightly against their palm were more likely to donate than those who held the pen loosely. This suggested that muscle tightening helped them fight selfishness and strengthened their resolve to help others.
In another experiment, participants who gripped a pen tightly were able to hold their hand in painful ice water for a longer duration. Additionally, when asked to consume an unpleasant "health tonic" (water with vinegar), participants who were asked to clench their calves drank more of it, especially if they were primed with sentences like "fitness is a virtue."
Real-Life Applications
The findings of these studies have interesting implications in understanding human behavior. For example, it could explain why footballers clench their fists by their sides when waiting for a potentially painful free-kick. It may also shed light on the phrase "get a grip" when someone's emotions are running high. Furthermore, the research suggests that clenching your muscles can help you resist temptation and make healthier choices, as demonstrated by students who bought healthier snacks after tensing their hand muscles.
Therefore, the simple act of clenching your fists or tightening your muscles may be a useful tool to increase your willpower and self-control in various situations, whether it's enduring physical pain, making healthier food choices, or even saying no to that tempting dessert.

Clenched fist syndrome
Clenching your fists is associated with increased willpower and endurance. However, when this action becomes a persistent and involuntary condition, it is known as Clenched Fist Syndrome (CFS). CFS is a rare psychiatric disorder characterised by flexion contracture of several digits or, in severe cases, the entire hand. Patients exhibit tightly clenched hands or fingers, with pain, swelling, and stiffness. This syndrome is believed to be a type of conversion disorder, which is unconsciously motivated, or a factitious disorder.
CFS is not associated with any known organic disease, and finger extension is possible under anaesthesia. It is seen in all age groups and does not seem to be influenced by hand dominance. The prognosis for CFS is generally poor, and treatment can be challenging due to patients' lack of insight into the psychiatric nature of the condition and their reluctance to accept psychiatric treatment.
The underlying cause of CFS is unclear, and it is considered a clinical rarity. In most cases, it appears to follow a minor triggering event and is often accompanied by psychiatric comorbidities such as depression, schizophrenia, or obsessive-compulsive disorder.
One notable case study involved a 52-year-old woman who presented with a 6-month history of progressive hand flexion contracture and numbness in the first three fingers, resembling carpal tunnel syndrome. Despite consulting numerous hand surgeons, no abnormalities were detected through physical examinations, X-rays, or neurological tests.
CFS is an intriguing condition that remains a subject of interest for psychiatrists and hand surgeons due to its rarity and complex nature.

Cholesterol medications and muscle pain
Making a fist is an action primarily performed by the flexor digitorum superficialis and profundus muscles in the forearm. When making a tight fist, the flexor digitorum superficialis muscle is the main muscle responsible for pulling the fingers into a flexed position.
Cholesterol-lowering medications, specifically statins, are associated with muscle pain and cramps as a side effect. This pain is more common in women than in men. While statins are beneficial for preventing cardiovascular events, their side effects can be managed or alternative treatments can be considered.
If you experience muscle pain while taking statins, it is important not to stop the medication but to consult your doctor. They can help find ways to manage the pain and determine if any further tests or adjustments are needed. For instance, getting a thyroid blood test can be useful, as a low thyroid hormone level can be associated with muscle pain, and taking replacement thyroid hormone pills may provide relief.
Additionally, lifestyle changes can help alleviate statin-related muscle pain. Regular physical activity, such as 150 minutes of moderate exercise per week, can boost your "good" HDL cholesterol levels. It is important to note that while gentle stretching may relieve muscle cramps, starting a new vigorous exercise regimen while taking statins may increase the risk of muscle pain. A heart-healthy diet, such as the Mediterranean diet, can also help lower your cholesterol and potentially reduce your statin dosage.
If muscle pain persists or becomes intolerable, there are non-statin cholesterol-lowering medications that your doctor may recommend. These include ezetimibe, bile acid sequestrants, PCSK9 inhibitors, and adenosine triphosphate-citrate lyase (ACL) inhibitors.

Reducing stress to prevent clenching
While clenching your fists may seem like a violent reaction, it can help you deal with stress. The action of clenching your fist can help you ease pressure, boost memory, and enhance willpower. However, clenching your fists is often a physical manifestation of stress, and reducing stress can help prevent fist clenching.
To reduce stress and prevent clenching, it is important to first become aware of the physical signs of stress, such as a clenched jaw, furrowed brows, or a scowl. These signs indicate that you may be fixated on a particular thought or situation, which can lead to rumination and sadness.
Once you become aware of these physical manifestations, you can take steps to relax and release the tension. Just as you consciously clenched your fist, you also have the power to relax it. You can open your fingers, shake your hand to improve blood flow, and focus on the present moment rather than the past or future.
Additionally, you can try to identify and address the underlying causes of your stress. This may involve making lifestyle changes, such as improving your sleep habits, engaging in physical activity, or practicing relaxation techniques like deep breathing or meditation.
By reducing stress and becoming more aware of your physical reactions, you can prevent clenching your fists and improve your overall well-being.

Babies clench fists before falling asleep
Clenching fists is an instinctive reflex in infants known as the palmar grasp reflex. It is a natural part of their neuromuscular development and will typically decrease as they grow older. Babies typically clench their fists before falling asleep and then start to loosen their grip after falling asleep. This primitive motion is also called the palmar grasp, and you can trigger it by softly stroking your baby's open palm with your finger. Clenching their fists can also provide babies with a sense of security and comfort. It’s a way for them to self-soothe and feel reassured during feeding.
Babies have strong oral reflexes, which include rooting (turning towards a stimulus near their mouth) and sucking. Clenching their fists may be a part of this coordinated response during feeding. Some babies clench their fists to stimulate the flow of milk. This can be a way for them to control the pace of feeding and ensure they get enough milk.
Scientists studying human evolution offer a logical explanation for why babies clench their fists when feeding. A popular view is that they do it because the monkeys did it. Modern humans who seem to share a common ancestry with some species of upright-walking apes learned the vice-like grip from baby apes who hold on to their mother’s thick hair for survival as they hang in precarious positions while their mothers swing from treetops.
Babies have fingernails that could hurt their mother. The most fragile part of the womb is the thin amniotic sac that surrounds the baby. It is a nurturing membrane made up of complex biochemicals. Any pricking or scratching of this flimsy sac can lead to the release of hormones and chemicals that may induce premature labour. Thus, a baby’s clenched fist can be a way of preventing the baby’s fingernails from harming the amniotic sac.
If you or your baby's healthcare provider notices that a particular reflex, like clenched fists, persists longer than normal, it could signal a problem with your baby's nervous system. In rare cases, exaggerated reflexes could point to cerebral palsy or hypertonia, which is stiff muscle tone.
