An internal tremor is a felt tremor in the extremities or trunk without actual movement — a deep, inner vibration that can affect the chest, abdomen, or limbs, and is often more noticeable during stillness, including when falling asleep. It isn't debilitating, but it can be genuinely bothersome. In the largest survey to look at it, internal tremor was reported by 32.6% of people with Parkinson's, 35.9% of those with MS, and 54.5% of a small group with essential tremor, and it was associated with both anxiety and the presence of visible tremor (Cochrane et al., Parkinsonism & Related Disorders, 2015). The origin of the sensation is still unknown.
Common associations include:
- Parkinson's Disease
- Multiple Sclerosis (MS)
- Essential Tremor
Certain deficiencies — vitamin B12, iron, and vitamin D — can also produce neurological symptoms, including mild internal tremors upon waking. A B12 deficiency in particular can disrupt the nervous system and cause shaky or trembling sensations, which is why it's worth ruling out with a simple blood test (NIH Office of Dietary Supplements, Vitamin B12).
If you're experiencing nighttime vibrations and a tendency to wake up shaking, it can take a toll on your well-being. Several lifestyle strategies may help reduce how often and how intensely these sensations show up.
- Dietary adjustments — while diet alone won't eliminate tremor, a balanced intake of key nutrients supports neurological stability; our guide to the best vitamins for nerves and muscles covers this in detail.
- Exercise and physical therapy — targeted exercises that improve motor control can help, especially around transitions from rest to movement.
- Sleep hygiene — regular sleep patterns and fewer disruptions can reduce symptoms for people who notice internal tremors when waking.
- Herbal remedies — supplements like valerian root and passionflower are used to ease anxiety; they aren't a cure, but given the link between internal tremor and anxiety, calming that anxiety may offer subtle relief.
- Acupuncture — some people find it promotes relaxation and reduces neurological sensitivity, which may help those prone to internal tremors at night.
- Biofeedback — guided training to regulate physiological responses may, over time, lessen how often internal tremors occur.
Many people find their symptoms are heightened at transitional moments — drifting off, or waking. These times are more sensitive because of shifts in brainwave activity and hormonal balance, and addressing them through lifestyle changes can meaningfully improve comfort and stability. If your tremor is most noticeable first thing in the morning, our guide to why your hands shake covers the waking-tremor pattern in more depth.
Several sleep-related and systemic factors can set off or worsen the sensation:
- Sleep-related muscle movements — involuntary muscle activity during sleep can resemble tremor, particularly for those who notice internal tremors when falling asleep.
- Sleep disorders — conditions like sleep apnea or restless leg syndrome disrupt rest and can produce unexplained bodily sensations. If you've ever asked "why am I shaky when I wake up," a sleep evaluation may be worth exploring.
- Circadian-rhythm disruption — when the body's internal clock is out of sync, symptoms can worsen; managing light exposure and bedtime routines helps restore balance.
Targeted adjustments to sleep, nutrition, and movement can significantly influence symptom control — especially during vulnerable times like waking with internal tremors. Whether the driver is stress, a nutrient deficiency, or an underlying neurological condition, a holistic approach guided by your doctor is the most reliable path to steadier, more comfortable days.

One point worth being clear about: a wearable glove is not a treatment for the internal, felt vibration itself. The Steadi-3 Plus is built for visible, mechanical hand tremor — the kind you can see — not the inner buzzing that internal tremor describes. If your internal tremor comes alongside a visible hand tremor (and the two often travel together, as the research above found), the glove can help with that outward part. It's an FDA-registered Class I medical device that uses a passive magnetic vibration absorber (tuned mass damping) to counteract tremor as the hand moves, with no electronics or batteries. In Steadiwear's placebo-controlled validation study of visible tremor, 84% of wearers improved their tremor control versus using no device, and 70% improved versus a placebo glove (Steadiwear, Steadi-3 Plus validation study).
So if a visible hand tremor is part of your picture, a tremor-stabilizing glove can steady daily tasks like eating and writing. If your tremor is purely internal, treat that as a cue to look at the underlying cause with your provider rather than reach for a device — and always check with your healthcare provider about how any tool fits your personal care plan.
