Is there a difference between blood pressure in winter and blood pressure in summer?

Blood pressure in winter is different from that in summer: blood pressure in summer will be lower than that in winter.

People's blood pressure will vary with age, season, climate and occupation, and the blood pressure value will be different.

The temperature rises rapidly in hot summer. Due to the physical principle of thermal expansion and cold contraction, blood vessels in the human body also expand, vascular resistance decreases, and blood pressure decreases accordingly. At the same time, people sweat a lot in summer, and salt is excreted with sweat, just like eating a diuretic, which leads to a decrease in blood volume and blood pressure.

Extended data:

Compared with hypertension, hypotension is like a "silent sheep". When the upper limb blood pressure is lower than 90/60mmhg, it can be diagnosed as hypotension. In most cases, people will have obvious symptoms unconsciously, and only a few people will have symptoms such as cold hands and feet, general weakness, dizziness, palpitation, forgetfulness, etc. This is caused by insufficient blood supply to the brain due to rapid blood pressure drop.

Generally speaking, this physiological hypotension can be recovered without special drug treatment after timely nutrition supplementation and intake of water and salt, but if syncope and precordial pressure occur, you should be vigilant.

Hazards of hypotension:

Hypotension leads to insufficient blood supply to tissues, which is very harmful to body organs. Especially compared with young people, the elderly have poor self-regulation ability and weaker tolerance to low blood pressure than high blood pressure. It is easy to appear the manifestations of systemic organ hypoperfusion and ischemia, and even lead to more serious consequences such as ischemic stroke, angina pectoris and renal insufficiency.

The systolic blood pressure of elderly patients with hypertension should be no less than130mm Hg, and that of young people should be no less than120/75mm Hg. Those patients whose blood pressure has been well controlled need to adjust their medication in summer, and don't let too low blood pressure cause unnecessary burden to their bodies.

In hot and sweaty summer, avoid dehydration and replenish water and salt in time. At the same time, we should insist on self-examination of blood pressure. Once you find blood pressure fluctuation, you should seek medical advice in time and adjust the medicine under the guidance of a doctor.
