Can blood pressure make you tired?

If you’re finding it hard to keep your eyes open and stay focused during the day, there could be a number of different factors in play. One possibility that’s often overlooked is the impact of blood pressure on sleep quality and daytime fatigue. High or low blood pressure can both lead to feelings of tiredness, grogginess and general malaise – but why is this? In this article, we’ll explore how blood pressure affects your energy levels and what you can do to optimize your circulatory health.

The Basics: What Is Blood Pressure?

Before we dive into specifics about how blood pressure might cause fatigue, let’s first establish what exactly we mean by “blood pressure.” Essentially, it refers to the force with which our heart pumps blood through our veins and arteries. When doctors measure someone’s BP (blood pressure), they use two numbers: systolic (the top number) measures the maximum amount of force exerted when our heartbeats; diastolic (the bottom number) gauges resting pressures between beats.

High Blood Pressure And Fatigue

It may not seem immediately intuitive that high BP could make someone feel sluggish or sleepy – after all, isn’t hypertension associated more with excitement/anxiety than weariness? However,research has shown that chronic high BP levels increase risk for nervous system imbalances leading to extreme somnolence throughout waking hours.

But why does this happen? There are few potential explanations:

  • Buildup Of Plaque In Arteries: As plaque builds up inside arterial walls over time due chronic elevated BP levels symptomatic effects like getting exhausted become obvious.
  • Brain Fog Due To Poor Circulation: Reduced circulation in cerebral regions – caused by hypertension induced constriction in mineralocorticoid receptors leads particularly to cognitive functions impairment/mental exhaustion issues such as lackluster performance at work/school.
  • Sleep Apnea: Poor sleep can precipitate or exacerbate high BP, but another way around connection is less well-known: hypertension puts undue stress on respiratory muscles to generate flow enough for body oxygen needs while sleeping. A combination of these factors often contributes to chronically tired feeling in those with consistently elevated BP levels.

Low Blood Pressure And Fatigue

While high blood pressure may be the more commonly known cause of fatigue and it’s flip side symptoms,low blood pressure doesn’t get off scot-free either . People who suffer from hypotension (i.e. low BP levels) also have a higher risk of lethargy throughout the day – particularly when they change positions suddenly (e.g. standing up after sitting down). Here are some reasons why:

  • Impaired Oxygen Delivery To Brain.: Patients with low blood volume cannot squeeze their arteries hard enough pump sufficient oxygen saturated blood through vital organs due inadequate plasma content within them causing breathlessness occasionally.
  • Decreased Coordination Between Heart And Brain: Often seen in elderly populations, age-induced decline neural networks mediating circulation-system function renders weaker regulation normotensive values because chemical signals inciting heart contractions & relaxing smooth muscle inside vessels get slower/more irregular so deprived brain cells isn’t being provided enough electrical/molecularly charged resources which exhausts resistance mechanisms that keep people alert otherwise.
  • Nutrient Deficiencies : Certain vitamin/mineral deficiencies like B12 or folates prevent adequate hemoglobin production needed unloading as much O2 possible during periods physical activity which leads easily fatigued/unenergetic states even prolonged rest/sleep hours should not noticeably help.

What Else Can Cause Fatigue?

It’s worth noting that there are many other potential causes for feelings of tiredness beyond just circulatory issues – some common possibilities include:

  1. Lack Of Physical Activity:One major reason for persistent exhaustion could simply be failing to get regular exercise routine into your daily schedule.This is key to maintaining alertness though some tiredness from extensive exercise isn’t unnatural among persons prone overweight

  2. Poor Diet: What we eat and drink can have a powerful impact on our energy levels as well; if you’re not getting enough nutrients, hydration or too many unhealthy carbs/processed food in day-to-day meals it will be reflected demotion of body’s overall dynamism.

  3. Chronic Disease Or Illness:Many health conditions can cause extreme drowsiness – including depression, heart disease, viral infections like Covid-19 which recommend general public stay diligent with vaccination recommendations,is an ongoing example of the broad variety coexisting pathologies that lead general fatigue throughout bodily systems before being contained by targeted treatments

  4. Sleep Disorders : Cheaping out on rest leads to all sorts maladies stemming from anxiety/depression aspects social lives heavily impacted as individuals get more irritable without putting much thought into regaining their heavy sleep cycles.Top irregularities are chronic insomnia,repeated daytime sleep attacks caused by narcolepsy & restless leg syndrome


In conclusion, blood pressure has been associated with lethargy whether BP is high or low due numerous factors listed earlier.Maintaining healthy lifestyle within standard values for BP not only helps affording physically active productive schedule but boost mental capabilities providing opportunity thrive under regular circumstances than succumbing depleted states wherein daily routines become set apart changes personal inclinations.Start off building good habits crucial towards continued success!
