Stroke is increasingly affecting younger individuals and can happen to anyone. High-risk groups include: people over 50, those with a history of stroke, individuals with a family history of stroke (especially early-onset stroke under 40), and those with hypertension. People who regularly smoke, drink alcohol, consume excessive fatty and saturated foods, lead sedentary lifestyles, or are obese also face elevated risks.

Mild dizziness and blurry vision might result from heatstroke, heat exhaustion, stress, pressure, or lack of sleep.

Extreme hot weather increases health risks, particularly for vulnerable groups such as older adults, and individuals with cardiovascular disease, hypertension, diabetes, or a history of stroke. Therefore, you should remain vigilant and listen to your body to prevent stroke risks.

Note that a stroke-related headache is often sudden, unexpected, and described as a "thunderclap headache." Many patients experience disorientation, vomiting, or even collapse, reporting it as "the worst pain they have ever felt." The pain develops rapidly and is severe.

For early stroke recognition, refer to the B.F.A.S.T formula:

B (Balance): Sudden difficulty maintaining balance, staggering, or falling.

F (Face): Check for signs of facial drooping, asymmetry, or numbness.

A (Arm): Observe for arm weakness or numbness.

S (Speech): Notice if speech is slurred or difficult.

T (Time): Call emergency services immediately if any symptoms appear to avoid missing the critical treatment window.
