Is There a Cause-and-Effect Relationship Between Insomnia and High Blood Pressure?

A low blood sugar level can be the cause of insomnia. There are dietary changes you can make to help lower your blood sugar. High blood pressure can also result from sleep disturbances. Keeping blood sugar levels normal will help you sleep and avoid high blood pressure.

Low Blood Sugar Causes Insomnia

Studies have found that high blood sugar levels can affect sleep and physical health. People with diabetes are more likely to have short sleep durations, and they tend to wake up often during the night. They also feel more tired during the day and are more likely to eat comfort foods. A lack of sleep is not only uncomfortable, but also damaging to your health.

A diet that is high in fiber and low in sugar can help prevent these sleep disturbances. Whole grains like oatmeal are ideal bedtime snacks. These foods will balance your blood sugar levels and allow you to fall asleep more easily. In addition, these foods will increase the serotonin levels in your brain.

If you have diabetes or prediabetes, low blood sugar levels can also contribute to insomnia. Low blood sugar levels cause the release of hormones that regulate blood glucose levels, stimulate the brain, and signal when it’s time to eat. When these hormones are high, sleep is disrupted and you won’t be able to fall asleep.

Low blood sugar levels during the night can lead to sleeplessness, difficulty waking up in the morning, and lethargy. In some people, nighttime hypoglycemia is obvious and easy to avoid, but others can go unnoticed. Restless leg syndrome, also known as Ekbom syndrome, is another common symptom of low blood sugar. Symptoms of this disorder can include a burning or crawling sensation in the legs.

Dietary Changes Can Lower Blood Sugar Levels

People with high blood sugar levels tend to have difficulty sleeping. Often, they feel tired during the day and end up craving comfort foods. Because high levels of blood sugar are not well-regulated by the body, the best way to get a good night’s sleep is to make dietary changes.

You should aim to eat smaller meals throughout the day, and try to limit carbohydrates. Instead, eat proteins and vegetables. Eating small meals every two to four hours will help stabilize your blood sugar. Limiting sugar and starchy carbs can also help. In addition, try to limit your intake of high-fiber carbs before bed. Eating before bed can affect sleep

Sugary evening meals should be avoided, as they can increase blood sugar levels and cause insomnia. Eating high-protein snacks that have low carb content will help stabilize blood sugar levels and help you sleep better. In addition, vegetables, especially leafy greens, are particularly beneficial when it comes to lowering blood sugar and insomnia.

High blood sugar levels during the night can be caused by the dawn phenomenon, when the liver produces glucose early in the morning to give the body energy. People with diabetes may need to adjust their insulin basal dose or rate to compensate for this natural process.

Sleep Disturbances Can Lead To High Blood Pressure

Hypertension is a major contributor to cardiovascular disease. Thus, it is imperative to identify and treat hypertension as early as possible. Sleep disturbances affect the physiology of the cardiovascular system by provoking metabolic and neurohormonal changes. They are associated with an increased risk of cardiovascular events and resistant hypertension. Moreover, they impair the circadian rhythm of blood pressure. However, sleep disorders are often under-recognized, and management varies widely. According to a recent report by the Italian Society of Hypertension, there is an emerging body of evidence linking sleep disturbances with cardiovascular diseases.

Several studies have reported an association between short sleep and high blood pressure, but the evidence is mixed. Most studies examining the relationship between short sleep duration and hypertension use cross-sectional design. In addition, studies published after the 2017 update by the AHA/ACC continue to use the 140/80 mm Hg threshold for hypertension. However, despite these mixed results, the evidence supports the conclusion that sleep duration is a risk factor for hypertension.

Sleep is an essential part of our lives. It helps regulate hormone levels and helps the body recover from physical and mental stresses. When sleep is interrupted, the levels of hormones increase, leading to high blood pressure and other cardiovascular risk factors. Likewise, too much sleep can affect blood sugar levels and weight, and is detrimental to heart health. This is why it is so important to get adequate sleep to avoid the risk of hypertension. You must always try to know ways to sleep as soon as possible


Insomnia is associated with increased cardiovascular morbidity and mortality. This may be because sleep duration is significantly shorter in patients with insomnia. An altered BP profile during sleep could also explain this relationship. Insomnia may also be associated with nocturnal hypertension. Respiratory disorders may also be a factor, including OSA syndrome. This disorder causes repeated interruptions in breathing during sleep. This causes a change in the night-time rest quality, which can contribute to excessive daytime sleepiness and fatigue.
