Introduction
Cardiovascular diseases are one of the major threats to global health, especially in times of seasonal change. According to statistics, the incidence of myocardial infarction and moderate brain events has increased significantly in winter and summer. Understanding the effects of seasonal changes on cardiovascular diseases helps the general population to prevent and reduce health risks under different climatic conditions. This paper will help general human science to meet the challenges of cardiovascular diseases from the biological effects of seasonal changes, the causes of high morbidity and coping strategies.
1. The biological effects of seasonal changes on the human body
Temperature changes directly affect the blood vessels. In cold winters, low-temperature irritation leads to vascular constriction, leading to increased external resistance and increased heart burden. Rising blood pressure is an important factor in hypertensive stress and myocardial infarction. In hot summers, the human body spreads the heat and the blood vessels expand, which may lead to a decrease in blood pressure. However, high-temperature environments can also lead to increased dehydration and blood mucousity, increasing the risk of haematosis.
An additional burden on cardiovasculars due to poor day and night temperature. During the spring and autumn seasons, the temperature is much worse, and the body needs to adjust its blood vessels more frequently in order to cope with temperature changes and to increase the pressure on the vascular wall, especially for the elderly and chronically ill.
Changes in seasonal biological rhythms. Reductions in the time of winter sunlight could lead to increased hormonal demoxification and reduced blood pressure regulation. Rapid temperature fluctuations in the spring and autumn affect the balance of the symmetric and sub-sympathetic nerves and trigger heart rate and blood pressure fluctuations.
II. Causes of the high incidence of cardiovascular disease in different seasons
Winter: “peak period” for cardiovascular diseases. The cold induces vascular contraction: cold winter causes vascular contraction and increased blood flow resistance, leading to increased blood pressure. Increased blood viscosity: hypothermia stimulates adrenaline and deetrenalin generin, making it easier for slabs to accumulate and increasing the likelihood of leaching. Reduced activity and slower metabolism: reduced outdoor activity in winter and greasy diet may further increase the risk of obesity and high blood resin.
Summer: Invisible threats from cardiovascular events. Dehydration and electrolyte disorders: High temperatures lead to massive human sweating, and failure to replenish water and electrolyte in a timely manner leads to increased blood stickiness and increased heart burden. Thermal stress: High temperatures can trigger thermal stress, lead to an acceleration of the heart rate and increase the risk of acute heart failure and heart disorder. The dangers of heat and high blood pressure patients: high blood pressure patients who take urea pills are more likely to dehydrate in hot weather and may cause low blood pressure or even heart-borne fainting.
Spring autumn: Temperature fluctuations and blood pressure instability. Fluctuation of blood pressure due to poor day and night temperature: Cardiovascular patients may experience a sudden increase in blood pressure in the morning or at night, increasing the risk of infarction in the brain and myocardial infarction. Allergies and inflammations: Precipients such as spring and fall pollen and air pollution may induce inflammation and increase the risk of sclerosis or cardiovascular events.
III. How to respond to the effects of seasonal changes on cardiovascular vessels
Winter protection strategy
Keep your body warm: stay warm and warm when you go out. It is recommended to wear scarfs and hats, especially to protect the neck. Attention to blood pressure monitoring: periodic measurements of blood pressure, attention to changes in morning blood pressure, and adjustment of the dose of pressure-relief drugs if necessary. Low diet, adequate exercise: reduce fat, salty dietary intake, choose easy indoor exercise such as yoga or Taipo, and avoid excessive activity.
Summer preventive measures
Pay attention to refilling: Drinking enough water to avoid sugary drinks. In particular, in high-temperature environments, the timely resupply of desalination water or sporting beverages. Avoiding noon: Avoiding out during the high-temperature day, choosing morning or evening outdoor activities. Vigilance is high: more rest in high-temperature conditions, more gas jackets, and heat-depressants.
The spring and fall response
Beware of changes in blood pressure in the morning: Be careful to wake up slowly in the morning and avoid a sharp rise in blood pressure. It is recommended to sit for two to three minutes before moving. Reasonable exercise: Choosing aerobic aerobics, such as walking, riding, and avoiding early and late excessive temperature differentials. Allergies: Allergies are careful to wear masks to avoid direct contact with pollen and air pollution.
Health management throughout the year
Periodic check-ups: follow-up on changes in blood resin, sugar and blood pressure, particularly for high-risk groups, once every quarter. Following a medical prescription: persons with hypertension and coronary heart diseases take their medication on time and do not adjust their dosage at will. Learning about first aid: Basic knowledge of CPR, first aid drug use (e.g. aspirin) to respond to emergencies.
IV. Carnation tips
The high-risk groups pay particular attention to the risks posed by seasonal changes, including the elderly, the obese, diabetics, smokers and those with a history of cardiovascular disease. Mental health management: Seasonal mood fluctuations (e.g. winter depression) may indirectly affect cardiovascular health. Staying happy and participating in social events helps to reduce the risk of disease.
Concluding remarks
Seasonal change is an important factor in the impact of cardiovascular diseases, but the risk of disease can be significantly reduced through scientific preventive measures and health management. Each and every one of us should be concerned about his or her health, understand and respond to the challenges to his or her body posed by seasonal changes, so as to be able to avoid, treat and protect a healthy life.
