Why Sleep Symptoms Matter
During sleep:
- Blood pressure should dip
- Heart rate should slow
- Brain circulation should stabilize
If the brain or blood vessels are under stress, nighttime symptoms may appear before daytime ones. That’s why doctors increasingly consider sleep quality an important cardiovascular marker.
Symptom #1: Frequent Nighttime Numbness or Tingling
What It Feels Like
- Arms, hands, legs, or feet “falling asleep”
- Pins-and-needles sensation
- Burning or crawling feelings at night
Why It Matters
Persistent nighttime numbness may reflect:
- Reduced blood flow to nerves
- Poor circulation
- Blood vessel stiffness
- Nerve compression worsened by vascular issues
After 40, this symptom may be linked to:
- Early vascular disease
- Diabetes-related circulation changes
- Increased stroke risk factors
⚠️ Occasional numbness is common. Frequent or worsening numbness is not.
