You might suffer from Essential Tremor, or you could just be unlucky to have a set of genes causing you mild tremors or shaking in your finer extremities. Essential tremor is a movement disorder that causes involuntary, rhythmic shaking (tremor), especially in the hands. It is distinguished from tremor that results from other disorders or known causes, such as Parkinson’s or head trauma. Essential tremor usually occurs alone, without other neurological signs or symptoms. However, some experts think that essential tremor can include additional features, such as mild balance problems. Essential tremor usually occurs with movements and can occur during many different types of activities, such as eating, drinking, or writing. Essential tremor can also occur when the muscles are opposing gravity, such as when the hands are extended. It is usually not evident at rest. Essential tremor does not shorten the lifespan. However, it may interfere with fine motor skills such as using eating utensils, writing, shaving, or applying makeup, and in some cases these and other activities of daily living can be greatly impaired. Symptoms of essential tremor may be aggravated by emotional stress, anxiety, fatigue, hunger, caffeine, cigarette smoking, or temperature extremes. Essential tremor may appear at any age but is most common in the elderly. Some studies have suggested that people with essential tremor have a higher than average risk of developing neurological conditions including Parkinson disease or sensory problems such as hearing loss, especially in individuals whose tremor appears after age 65. Emotional Stress. According to the Mayo Clinic, the body’s apocrine glands secrete an oily sweat when a person is suffering from anxiety or emotional stress. Sulfur-producing bacteria thrive in these fatty compounds; they produce a chemical by-product that smells similar to a garlic odor.
Shaky hands are commonly referred to as a hand tremor. A hand tremor isn’t life-threatening, but it can make daily tasks difficult. It can also be an early warning sign of some neurological and degenerative conditions. You should speak with your doctor if you experience hand tremors. Many people associate shaky hands with Parkinson’s disease, but the most common cause of shaking hands is actually essential tremor. Essential tremor is also the most common neurologic disorder affecting adults, but it’s not well-understood. It’s likely caused by a disruption in the normal functioning of the cerebellum. Researchers aren’t entirely sure what causes the interruption nor how to stop it. They’re also unclear about whether it’s a degenerative process. People with essential tremor experience frequent shaking. The shaking can’t be controlled and most often occurs in the hands, arms, head, and vocal cords. There’s multiple reasons. First and most important one: our hands and face don’t tend to be covered by cothing, skin that is not covered and constantly exposed to the weather tends to lose heat more easily (simple thermodynamics), if the temperature of our surroundings is lower that that of our bodies then heat transfers. But that’s not the only reason, blood flow plays an important role too. A condition named Raynaud’s phenomenon consists on reduced blood flow secondary to vasospasm (a narrowing of the a blood vessels lumen due to muscular contraction in the blood vessels wall). This condition can be associated with some rheumatic diseases but not all people who have cold hands necessarily have a rheumatic disease. Also, cold hands can be associated with other diseases that require medical attention.
