Discovered a simple way to help the elderly lower high blood pressure
New research recently published in the medical journal JAMA Network Open , has found an incredibly simple way to help older adults who sit a lot lower their high blood pressure.
Older adults typically sit 65 to 80 percent of the time, and sitting increases the risk of chronic diseases such as heart disease and diabetes.
People who reduced their sitting time by about 30 minutes a day reduced their blood pressure by nearly 3.5 mmHg.
Officials at the Kaiser Permanente hospital system in the US said they have created a program to see if sitting less can help older adults lower their blood pressure.
The study included 283 overweight people aged 60 to 89 years.
Participants were divided into two groups: One group was asked to reduce their daily sitting time. The second group served as a control group, which did not change their sitting time or daily activities.
Results found that people who reduced their sitting time by about 30 minutes a day reduced their blood pressure by nearly 3.5 mmHg .
The researchers note that this reduction is equivalent to a 4 mmHg reduction with increased physical activity, while weight loss only reduces it by 3 mmHg.
According to the study authors, reducing sitting time can improve overall health. Readers can read more about this article on the health page on April 20.
How to use air conditioner effectively and economically on hot days
To use air conditioning effectively and economically on hot days, people need to set the temperature at an appropriate level and combine it with other cooling measures.
On hot days, many people choose to lower the temperature of the air conditioner to help create a more comfortable feeling. However, according to Ms. Jennifer Amann, an energy saving expert (USA), lowering the temperature like that does not actually cool the house.
People usually feel comfortable when the room temperature is between 21.6 and 25 degrees Celsius.
She and other experts say that lowering temperatures will only put more pressure on air conditioning, which already has to work harder in hot weather. It will also increase electricity costs, put more strain on the grid and potentially cause blackouts during peak demand periods.
Here are some ways to use air conditioners safely and save energy on hot days .
A study conducted at the University of Georgia campus in the summer of 2014 found that people generally feel comfortable when the indoor temperature is between 21.6 and 25 degrees Celsius. Therefore, experts recommend that people set the air conditioner temperature at this level when they are in the room.
And when you are away, experts advise people to set the air conditioner temperature 1 to 3 degrees Celsius warmer than the normal level they feel comfortable. This temperature will help keep the room cool and save electricity. The next content of this article will be on the health page on April 20.
Severe heat: Great tips to 'escape the heat' if there is no air conditioning
Severe heat is occurring in many places. However, many homes do not have the means to install air conditioning, so how can we cope with the heat?
Dr. Melissa Conrad Stoppler, a pathologist working in the US, shares steps that can help you stay cool during a heat wave even if your home doesn't have air conditioning.
Severe heat is occurring in many places.
On cooler evenings, open all windows and turn on fans to promote as much air circulation as possible.
When the sun comes up, close all the doors and windows, remembering to close the blinds and curtains to keep the house cool as long as possible.
When the outside temperature drops (usually in the evening or at night), open the windows and turn the fan back on.
Filling a bucket or basin with water and soaking your feet is a great way to stay cool. Placing or draped a wet towel over your shoulders or head can also have a cooling effect. Take cool showers and use a spray bottle filled with cold water to spray yourself with a refreshing spray throughout the day.
Because hot air rises, the upper floors of a house will be hotter than the ground floor. The ground floor can be a cool refuge from the midday heat. Start your day with health news to see more content of this article!
