It is common for people to experience muscle tension when they are excited. This phenomenon is not limited to adults and is observed in children as well. For instance, a parent noticed that their two-year-old child would tense up and flex their arms when excited. The child would also curl their fists and open their mouth, and this behaviour would last for about 2-3 seconds. Another parent observed that their four-year-old grandchild would grip their hands and tuck them under their chin or chest when excited. This behaviour is not limited to children and is also observed in adults. For example, a Reddit user reported tensing up their body while playing a video game they hadn't played in a while. Muscle tension can be caused by an increase in excitatory messages from the nervous system. Emotions such as adrenaline, stress, or anxiety can stimulate these messages, which are released from the brain and travel down the spinal cord into the nerves.

What You'll Learn
Muscle tension and excitement
Muscle tension can be caused by an increase in excitatory messages from the nervous system. Emotions such as adrenaline, stress, or anxiety can stimulate these messages. When a person is excited, their body may release adrenaline, which can lead to increased muscle tension. This is a natural response to excitement and is often nothing to worry about.
Several people have reported that they or their children tend to tense their bodies when they are excited. This behaviour is more commonly observed in children, who may clench their fists, curl their arms, or shake their bodies when excited. This tensing typically lasts only a few seconds and does not interfere with their regular activities.
In some cases, muscle tension can be a result of muscle contractures, which are mechanical responses in the muscles causing them to shorten. This can be due to the formation of collagen fibres in the muscles, which can restrict movement and lead to knots and increased muscle tightness. Poor posture can also contribute to muscle tension by creating a load on the muscles, leading to contraction.
To relieve muscle tension, massage can be beneficial. Massage helps to relax the muscles, increase circulation, and stimulate the healing process. It can also reduce tightness by applying pressure to knots and breaking down adhesions, allowing the muscle fibres to realign and lengthen.

Muscle contractures
Muscle contracture is a type of scarring in body tissues. It is most visible when it affects the skin, causing areas of skin to become shrunken and constricted, as in the case of severe burn injuries. In other tissues, such as muscles or ligaments, scarring is called fibrosis, where rigid and fibrous tissue replaces normal tissue, leading to a loss of elasticity and movement.
Treatment for muscle contractures includes physical therapy, casts or splints to keep the joint extended, medication to relax the joints and reduce inflammation, nerve blocks, electrical stimulation, and in severe cases, surgery to lengthen muscles and repair ligaments, tendons, or bones.

Knots in muscles
Muscle tension can be a natural response to excitement. When people get excited, they sometimes tense up their bodies. This can be due to the excitement of starting a game or watching a movie.
Muscle knots are a common cause of muscle pain. They can be caused by staying in an uncomfortable position for too long. To relieve the pain, you can try moving around or doing some gentle stretching exercises. Stretching can also help prevent muscle knots from forming in the first place.
If you often get knots in certain areas, consult a doctor about specific stretches to target those muscles and reduce the likelihood of knots occurring. Alternating ice and heat treatments can also help alleviate muscle pain. Apply an ice pack to the affected area, then switch to a warm compress or heating pad.
Trigger point massage is another effective technique for releasing muscle knots. This involves applying firm pressure to the knot using your hands or a foam roller. You can do this several times a day until the muscle pain subsides.
For severe or persistent muscle knots, medical intervention may be necessary. Myofascial pain syndrome, characterised by a tendency to develop muscle knots, can be treated with physical therapy, myofascial release therapy, dry needling, or injections of numbing medicine.

Muscle stimulation and nerves
Additionally, muscles can also tighten due to muscle contractures, which are mechanical responses causing muscles to shorten. Poor posture, whether standing, sitting, or lying down, can contribute to muscle tension and load. Muscle contractures can further lead to an increase in muscle tone, resulting in hyperactivity and constant contraction.
In some cases, individuals, especially children, may exhibit behaviours such as tensing their bodies or curling their fists when excited. This behaviour typically lasts for a few seconds and is often followed by a return to normal. It is believed that this behaviour may be a way to relieve excitement or pressure, as if the individual is unable to contain their enthusiasm.
Furthermore, massage is a commonly recommended treatment for tight muscles. Massage helps to relax the muscles by separating and loosening muscle fibres, elongating and stretching them, and reducing tension. It also increases temperature in the soft tissues, stimulating a relaxation response and producing inhibitory messages from the nervous system to counteract the excitatory messages that cause muscle tension.

Muscle tension in children
Muscle tension is a common occurrence, and it is not limited to adults alone. Children also experience muscle tension, and this can be triggered by several factors. In a study published in the International Journal of Behavioral Medicine, 42 children aged 7 to 15 were asked about their experience of bodily tension. 38 out of the 42 children said they had experienced muscle tension, and 32 of them could describe it using words like "jittery," "stiff," "tight," and "unpleasant." These 32 children could also describe where in the body they felt the tension, with common locations being the abdomen, head, legs, and arms.
The study also revealed that 36 of the children experienced muscle tension due to stressful life events. Furthermore, 14 out of the 42 children experienced pain in areas of the body where they had muscle tension, such as the stomach and the head. This indicates that children can identify the sensation of muscle tension, its location, and the factors that trigger it.
Another study focused on jaw muscle tension in children with suspected muscle-tone abnormalities, such as Down syndrome or spastic cerebral palsy, and compared them with age- and gender-matched controls. The study used two measures to infer jaw tension: a kinematic index of mass-normalized stiffness and electromechanical delay (EMD). However, the results did not show any significant differences between the groups in terms of jaw movement and muscle activation.
While muscle tension can be a normal response to stress or excitement, prolonged or excessive muscle tension can interfere with a child's daily life and cause pain. It is important for parents and caregivers to help children identify and manage muscle tension through relaxation techniques, stress reduction, and, if necessary, seeking professional help.

Frequently asked questions
Yes, muscles can tense up when a person is excited. This is due to an increase in excitatory messages from the nervous system. Emotions such as adrenaline, stress, or anxiety can stimulate these messages.
When the muscles receive these messages, they can become hyperactive and constantly contracted. This can lead to the formation of collagen fibers in a crisscrossing pattern, causing knots and restricting movement.
Massage is a common way to relieve muscle tension. It helps to separate and loosen muscle fibers, elongate and stretch the muscles, and decrease muscle tone.
Yes, muscles can also tense up due to poor posture, emotional stress, or muscle contractures, which are mechanical responses in the muscles causing them to shorten.
