When will it rain and snow tomorrow?

It will rain and snow from day to night tomorrow.

Impact and suggestion

1. Rain and snow weather plays a positive role in purifying the air and reducing the fire danger of forest and grassland.

2. During the precipitation, the visibility is reduced and the ground is slippery, reminding the traffic management department to strengthen monitoring and management.

Recently, heavy rain and snow have occurred in many parts of the country, and the temperature has plummeted. Experts suggest that the winter climate is cold, and the incidence of cardiovascular diseases generally rises, which is more likely to happen in the weather of continuous low temperature, rain, snow and strong wind. The public should pay more attention to cardiovascular health.

Why are cardiovascular problems more likely to occur in low temperature environment? Zhou Xiaoming, deputy director of the Department of Respiratory Medicine of the National Cardiovascular Center and Fuwai Hospital of China Academy of Medical Sciences, said that due to the large temperature difference between indoor and outdoor in winter, human blood vessels contract and relax rapidly, but in order to maintain body temperature at low temperature,

It will contract peripheral blood vessels, increase the burden of pumping blood from the heart, easily lead to an increase in blood pressure and increase the amount of blood returning to the heart. These are severe tests for patients with cardiovascular diseases.

Especially in some extremely cold and low-temperature weather, the sympathetic nerve of human body is excited, which makes the heart rate increase, blood pressure increase, systemic blood vessels contract, peripheral resistance increases, and myocardial oxygen consumption increases, which is more likely to form thrombus, cause acute blockage of lumen and easily lead to acute myocardial infarction.

Cardiovascular experts in Fuwai Hospital of China Academy of Medical Sciences suggest that getting up in the morning at a fast pace, outdoor activities at low temperature, and taking a bath or sauna for too long may all become "high-risk moments" for cardiovascular diseases.

The cardiovascular system is most vulnerable in the morning, and the risk of myocardial infarction and sudden cardiac death peaks in the morning. After a night's rest, my blood pressure is relatively low. After waking up, blood pressure will rise rapidly, especially in patients with high blood pressure in the morning.

Patients with a history of cardiovascular disease should get up, get dressed immediately, brush their teeth and wash their faces quickly. It will cause the vagus nerve that controls heart rate and blood pressure to be too late to adapt to adjustment.

Experts advise not to get up immediately after waking up in the morning. Lie flat and simply move your limbs and head, and then get up after 3 to 5 minutes. Don't open the window immediately to blow cold air or wash it with cold water.
