Medical experts have provided insights into the various causes of physical sensations experienced during the night, specifically focusing on heart palpitations and numbness. Initial discussions highlighted that nighttime palpitations do not always signify heart disease. Factors such as stress, anxiety, insomnia, caffeine, and alcohol consumption can increase heart rate. Other medical possibilities include anemia, hyperthyroidism, and heart rhythm disorders. Experts recommend urgent evaluation if palpitations are paired with chest pain, shortness of breath, or dizziness. Subsequent information expanded these findings to include nocturnal numbness in the hands, or paresthesia. This is often attributed to sleeping positions that restrict blood flow or compress nerves, though recurring issues may indicate carpal tunnel syndrome or spinal issues like cervical spondylosis. Regarding palpitations, experts noted that while silence or certain positions can exacerbate the sensation, underlying causes may also include dehydration, heartburn, specific medications for blood pressure or depression, and sleep apnea. Recent updates have further detailed the causes of paresthesia, noting that recurring numbness may also be linked to vitamin B12 deficiency, herniated discs, or peripheral neuropathy associated with diabetes. The impact of sleep quality has also been expanded to include the effects of partner snoring, which can lead to hormonal imbalances and memory issues. Additionally, experts noted that falling asleep immediately may indicate chronic sleep deprivation. To improve sleep hygiene, neuroscientist Andrew Huberman suggests specific breathing techniques and eye movements to calm the amygdala, while other professionals recommend progressive muscle relaxation and consistent routines.
