Home remedies · Sleep, nerves & head
No home remedy here replaces treatment, and none is talked down. What has done good for generations does good — even if no one ever measured it. Where something is well studied, it says so. Where it is only experience, it says that too.
Sit up in bed first, stay sitting for 30 seconds, tense the calves a few times, then stand. If things go black, sit or lie down at once and raise the legs.
On standing, blood pools in the legs and blood pressure drops for a few seconds. The pause and the calf pump give the circulation exactly those seconds.
It helps with circulatory dizziness, not with spinning vertigo — the two feel different: going black versus a carousel.
Anyone who repeatedly collapses on standing, gets hurt doing so, or goes black while sitting or lying needs assessment. Water tablets and blood pressure drugs are a common and readily corrected cause — bring the medication list.
Get seen at once: the sudden, worst headache of your life, headache with fever and a stiff neck, with weakness, speech or vision trouble. Likewise dizziness with double vision or an unsteady gait. Sleeplessness over weeks with loss of drive is something to discuss, not to endure.
