Sleep

Hello Doctor: Every time I catch a cold and visit the doctor, they tell me that it's due to insufficient sleep, stating that I only sleep for 2 to 3 hours.
My blood pressure readings show a systolic pressure of 90 mmHg and a diastolic pressure of 40 mmHg, and sometimes it can be even lower.
Can a cold cause low blood pressure? Sometimes I suddenly feel weakness in my limbs, which feels similar to the effects of taking too much medication, but I haven't taken any medication.
Why is this happening? If I want to undergo tests to find out the cause of my sleep deprivation, what tests should I consider? I've heard that blood tests and liver function tests are necessary, but I've had those done at school, and everything was normal.

Hello, Miss Candy: Human sleep is regulated by the natural phenomenon of the Earth's day-night cycle, where the brain receives signals indicating that it is time to rest and sleep at night.
Human blood circulation, which contains energy, is essential for life and also serves to store energy during nighttime sleep for daytime activities.
Therefore, if one experiences chronic sleep deprivation and insufficient energy storage, it can lead to a decreased immune response, resulting in symptoms such as frequent colds, weakness in the limbs, dizziness, and low blood pressure.
It is advisable to develop a routine of going to bed early and waking up early for better health!

More Info

Sleep deprivation can have significant effects on both physical and mental health, including its impact on blood pressure. When you mention that your doctors have attributed your frequent colds to sleep deprivation, they are likely highlighting the connection between inadequate sleep and a weakened immune system. Sleep is crucial for the body to recover and regenerate, and insufficient sleep can lead to increased susceptibility to infections, including the common cold.

Regarding your blood pressure readings, a systolic pressure of 90 mmHg and a diastolic pressure of 40 mmHg indicate hypotension (low blood pressure). While acute illnesses like colds can sometimes lead to temporary drops in blood pressure due to factors such as dehydration, inflammation, or the body's response to infection, chronic low blood pressure can be concerning. It can lead to symptoms such as dizziness, fainting, and weakness, which you described as feeling "four limbs weak." This sensation can also be exacerbated by sleep deprivation, as lack of sleep can affect the autonomic nervous system, which regulates blood pressure and heart rate.

If you are experiencing these symptoms without taking medication, it is essential to consider other factors that might be contributing to your low blood pressure and overall health. Sleep deprivation can lead to various physiological changes, including hormonal imbalances, increased stress hormones like cortisol, and alterations in heart rate variability, all of which can impact blood pressure regulation.

To investigate the underlying causes of your sleep deprivation, it would be beneficial to undergo a comprehensive evaluation. Here are some steps you might consider:
1. Sleep Study (Polysomnography): This is the gold standard for diagnosing sleep disorders. It can help identify issues such as sleep apnea, which is characterized by interrupted breathing during sleep and can lead to significant drops in oxygen levels, affecting overall health and blood pressure.

2. Home Sleep Apnea Testing: If a full sleep study is not feasible, some healthcare providers may recommend a home-based sleep apnea test, which can monitor your breathing patterns and oxygen levels during sleep.

3. Blood Tests: While you mentioned that previous blood tests showed normal results, it might be worth repeating them to check for any underlying conditions that could contribute to fatigue and low blood pressure, such as thyroid function tests, adrenal function tests, and complete blood count (CBC) to rule out anemia.

4. Cardiovascular Evaluation: Given your low blood pressure readings, it may be prudent to consult a cardiologist. They can perform tests such as an echocardiogram or an electrocardiogram (ECG) to assess heart function and rule out any cardiac issues.

5. Mental Health Assessment: Since sleep deprivation can also be linked to anxiety and depression, a mental health evaluation may help identify any psychological factors contributing to your sleep issues.

6. Lifestyle and Sleep Hygiene Review: Consider discussing your daily routines, stress levels, and sleep environment with a healthcare provider. Improving sleep hygiene—such as maintaining a consistent sleep schedule, creating a restful sleep environment, and managing stress—can significantly enhance sleep quality.

In summary, sleep deprivation can lead to a cascade of health issues, including low blood pressure and increased vulnerability to infections. It is essential to address both the symptoms you are experiencing and the underlying causes of your sleep deprivation. A multidisciplinary approach involving your primary care physician, a sleep specialist, and possibly a cardiologist or mental health professional may provide the best pathway to improving your health and well-being.
