The elderly in winter stroke (also known as stroke) is the most likely to be high, because the cold air will produce adverse stimulation, blood pressure increases, blood vessels in the cold will become hard and brittle, for the occurrence of stroke “ambush”. Three dangerous places 1, the bathroom in winter a hot bath is very comfortable, but cardiovascular disease patients do not long hot bath. This will cause the body to sweat a lot, resulting in thick blood, the risk of thrombosis; heat will also make the subcutaneous blood vessels expand, so that more blood flow to the subcutaneous tissue, resulting in heart, cerebrovascular and other relative ischemia, but also easy to increase the risk of stroke. The water temperature should not be too high, and do not enter the bathtub at once, it is best to end within half an hour. Undressing and dressing place should also be insulated. 2.Morning exercise field The early morning temperature in winter is very low, cold stimulation is easy to induce stroke. It is best to go out at the warmest time of the day, and to be well equipped, wearing a hat, scarf, gloves; it is best to practice with a partner, to avoid “playing unilateral” and more strenuous activities; the time of morning practice should not be too long. 3, on the toilet For patients with cardiovascular disease, especially hypertensive patients, the “No. 1 event” (defecation) is actually the top priority. Do not be impatient when defecating, hold your breath and force, so as not to increase the risk of cerebral hemorrhage. It is best to use a sitting stool to relieve fatigue. Patients who have habitual constipation must eat more vegetables and fruits and other foods to laxate the bowels. If necessary, you can also take laxatives to relieve difficult bowel movements. Five red flags There are warning signs that a stroke is occurring. About 30% of ischemic stroke patients will have a small stroke warning before the onset of stroke. Catching this important warning for timely treatment can curb the damage caused by stroke in advance. Patients with hypertension, hyperlipidemia and diabetes should be aware of the following five signs: 1) transient dizziness, 2) transient limb weakness, 3) transient blurred vision, 4) transient unfavorable speech, 5) transient limb numbness, etc.
