New evidence linking lifestyle factors to blood pressure: Focus on 2024 findings

Key Result

Recent evidence highlights that lifestyle modifications, particularly addressing sleep apnea, air pollution exposure, and dietary sodium and potassium intake, significantly improve blood pressure management.

Key Points

This review aims to examine the relationship between lifestyle factors and blood pressure based on recent studies from 2024.
Summarized recent research published in Hypertension Research and other journals from 2024 to mid-2025.
Focused on studies examining the effects of sleep, air pollution, and dietary factors on blood pressure.
Identified significant links between sleep quality and blood pressure levels.
Found that high sodium intake is associated with elevated blood pressure, while potassium may help lower it.
Highlighted the detrimental effects of air pollution on blood pressure management.

Structured PICO

Do lifestyle modifications and related interventions targeting sleep, air pollution, and dietary factors improve blood pressure and reduce hypertension risk?

Population

Patients with or at risk for hypertension, including those with obstructive sleep apnea, exposed to air pollution, or undergoing dietary modifications

Intervention

Lifestyle modifications and related treatments (including sleep apnea treatments such as tirzepatide, MAD, and CPAP; air quality improvements via clean fuel or HEPA filters; and dietary changes including sodium restriction, potassium supplementation, and dietary fiber)

Comparator

Standard care, no intervention, or alternative treatments (e.g., solid fuel, sham filtration, or different antihypertensive drug classes) depending on the specific study reviewed

Outcome

Blood pressure reduction and incident hypertension risksurrogate

This review highlights recent evidence reinforcing the critical role of lifestyle modifications—specifically addressing sleep disorders, air pollution, and dietary sodium/potassium—in blood pressure management.

Limitations

Much remains unknown about the underlying mechanisms linking lifestyle factors to blood pressure regulation.
Heterogeneity in the definitions and measurement methods across studies limits some evidence, such as for meal timing.

Abstract

Abstract Lifestyle is closely linked to blood pressure (BP), making lifestyle modification essential for BP management. In 2024, numerous intriguing studies were reported on lifestyle factors and BP. This mini review summarizes notable research on lifestyle factors and BP published in Hypertension Research and other leading journals from 2024 through the first half of 2025, with particular focus on sleep, air pollution, and dietary factors (mainly sodium and potassium).
