Poor sleep quality increases hypertension risk, cardiologist warns

Poor sleep quality and inadequate rest significantly increase individual hypertension risk, directly impacting long-term cardiovascular health.

Max Super Speciality Hospital, Vaishali, Senior Director and Head of Interventional Cardiology Dr Gaurav Minocha, explained that insufficient or fragmented rest elevates blood pressure levels over time. Uncontrolled high blood pressure gradually damages blood vessels, alters hormone levels, and increases heart rate without displaying obvious warning symptoms. Early indicators of sleep deficiency include eye redness, heaviness, persistent headaches, and general restlessness during waking hours.

To protect cardiovascular health, Dr Minocha outlined several vital sleep habits designed to lower high blood pressure risks:

• Maintain consistent sleep schedules by going to bed and waking up at identical times daily to support internal body clocks.
• Prioritise high sleep quality over total duration, as frequent night awakenings keep the nervous system in a stressed state.
• Minimise screen time before bed to prevent blue light exposure from suppressing natural melatonin production.
• Avoid heavy late-night meals, alcohol, and excessive caffeine, which disrupt digestive processes and interrupt deeper sleep cycles.
• Monitor night-time behaviours, as loud snoring, choking sensations, or daytime exhaustion can indicate obstructive sleep apnoea.

Because high blood pressure often develops silently without visible signs, medical professionals recommend routine blood pressure screenings. Dr Minocha advised individuals maintaining hectic schedules alongside poor sleep quality to seek timely medical evaluations to safeguard their cardiovascular systems.
