Experiencing nighttime heart palpitations and sensations of cold can be distressing and may indicate underlying issues that warrant further investigation. Based on the symptoms you've described, it seems you are facing a combination of physical discomfort and anxiety, which can significantly affect your sleep quality and overall well-being.

Firstly, let's break down the symptoms: you mention feeling cold and experiencing significant head pain accompanied by noticeable heart palpitations. These symptoms can be interconnected and may stem from several factors, including anxiety, stress, or even physiological responses to your environment.

1. Anxiety and Stress: Anxiety can manifest in various physical symptoms, including heart palpitations, cold sensations, and headaches. When you are anxious, your body enters a state of heightened alertness, which can stimulate the sympathetic nervous system. This can lead to an increase in heart rate and blood pressure, as well as sensations of cold or chills due to altered blood flow. The head pain you experience might be tension-related, often exacerbated by stress and anxiety.

2. Sleep Environment: You mentioned that you do not feel cold before bed but experience it once you lie down. This could be related to your sleep environment. If your bedroom is too cold or if you are not adequately covered, your body may react by feeling cold, which can further exacerbate feelings of discomfort and anxiety. It’s essential to ensure that your sleeping environment is conducive to rest—comfortable bedding, appropriate room temperature, and minimal noise can help.

3. Physiological Responses: The sensation of cold and the heart racing could also be a response to a drop in blood pressure or changes in your body’s circulation when you lie down. If your blood pressure tends to be on the lower side, as indicated by previous readings (90/60), this could contribute to feelings of dizziness or coldness, especially when transitioning to a lying position.

4. Possible Medical Conditions: While anxiety and environmental factors are common culprits, it’s also essential to consider other medical conditions that could be at play. Conditions such as hyperthyroidism, anemia, or even cardiac issues can present with symptoms like palpitations and cold sensations. Given your history of palpitations and discomfort, it would be prudent to consult with a healthcare provider for a thorough evaluation. They may recommend tests such as an electrocardiogram (ECG) or blood tests to rule out any underlying conditions.

5. Lifestyle Factors: Your lifestyle choices, including sleep patterns, diet, and exercise, can significantly impact your symptoms. Regular physical activity can help regulate your heart rate and improve overall cardiovascular health. Additionally, practicing relaxation techniques such as deep breathing, meditation, or yoga can help manage anxiety and improve sleep quality.

In conclusion, while your symptoms may be linked to anxiety and environmental factors, it is crucial to consult with a healthcare professional to rule out any serious underlying conditions. Keeping a symptom diary, noting when the palpitations and cold sensations occur, and any associated factors can provide valuable information for your healthcare provider. Prioritizing a healthy lifestyle, managing stress, and ensuring a comfortable sleep environment can also contribute to alleviating your symptoms and improving your overall quality of life.
