How does brisk walking help prevent heart disease?

Walking is an easy form of exercise that is suitable for all ages. Studies show that brisk walking significantly reduces the risk of heart rhythm disorders, especially atrial fibrillation.

A healthy heart beats at a regular rhythm to pump blood throughout the body. However, when suffering from arrhythmia, the patient experiences a condition where the heart beats too fast, too slow, or the beat is interrupted. Common arrhythmias are tachycardia, bradycardia, atrial fibrillation, and ventricular fibrillation.

A study published in the journal BMJ Heart analyzed data from more than 420,000 people. The results showed that people who walked quickly had a 43% lower risk of developing arrhythmias than people who walked slowly.

Brisk walking is generally understood as walking at a speed of about 4 miles per hour. However, the speed at which you should briskly walk to achieve optimal health benefits depends on your physical condition. Another effective way to determine your correct brisk walking speed is to use a smartwatch or heart rate monitor. The ideal heart rate for brisk walking or moderate exercise is about 50-70% of your maximum heart rate.

The maximum heart rates for people in their 20s, 40s, and 60s are 200, 180, and 160 beats per minute, respectively. For a 40-year-old, for example, the ideal heart rate range is 90–126 beats per minute. The next content of this article will be on the health page on May 3.

Scientists find a way to use air conditioners to cool down while saving electricity

In the intense heat, keeping cool is a major concern, especially for the elderly, pregnant women and people with heart disease.

The solution is usually to use air conditioning. But do you know how to use air conditioning to both cool and save electricity?

Only turn on the air conditioner when the indoor temperature exceeds 27 degrees Celsius.

In a study recently published in the Medical Journal of Australia, scientists from the Center for Heat and Health Research, University of Sydney (Australia), have found a simple but effective solution to using air conditioning. That is the "pre-fan cooling method".

The method is simple: Use an electric fan first to cool down and only turn on the air conditioner when the indoor temperature exceeds 27 degrees Celsius.

Electric fans can provide comfort on a hot day by moving air around. This helps the body release heat in two ways: improving the transfer of heat from the body to the air and increasing the evaporation of sweat from the skin.

A gentle breeze from a fan can help you feel more comfortable in hot and humid weather. This allows you to increase the air conditioner's temperature setting from 23 - 24 degrees Celsius to 27 - 28 degrees Celsius. This simple change can significantly reduce the time the air conditioner runs, helping to save a lot of electricity. The next content of this article will be on the health page on May 3 .

Feeling exhausted and irritable: When is it due to a vitamin deficiency?

If a person feels unusually tired, irritable, or has difficulty concentrating, the problem may be more than just stress or lack of sleep. These symptoms are likely signs of a vitamin B12 deficiency.

Vitamin B12 is an essential micronutrient that plays a vital role in converting nutrients into energy, nerve function, and mood regulation. Symptoms of vitamin B12 deficiency are often overlooked because they can be mistaken for other health problems.

When lacking vitamin B12, the body will also experience the following symptoms:

Cognitive impairment. In addition to fatigue, people with vitamin B12 deficiency may experience difficulty concentrating, forgetfulness, or a "fuzzy" feeling in their heads.

Neurological symptoms. Long-term vitamin B12 deficiency can lead to nerve damage. Warning signs of this condition include numbness or tingling in the limbs, muscle weakness, and difficulty maintaining balance.

Pale or yellow skin. A decrease in red blood cells due to a lack of B12 can lead to anemia, which can be characterized by pale or slightly yellow skin. Start your day with health news to read more about this article!
