Brushing Teeth Three Times a Day Reduces Heart Attack Risks

Brushing your teeth at least three times a day could lower the risk of heart failure by more than 10 percent, a study has found.

Researchers linked it to a lower risk of heart failure and atrial fibrillation, a condition that causes an irregular heart rate.

It is thought that frequent brushing reduces bacteria living between the teeth and gums, preventing it from entering the bloodstream.

Scientists in South Korea examined the connection between oral hygiene and heart problems in the study of 161,000 people aged between 40 and 79. They had a routine medical examination between 2003 and 2004.

By the time of a follow-up ten years later, around 5 percent had developed heart failure and three percent atrial fibrillation.

Brushing three or more times a day was associated with a 12 percent lower risk of heart failure and a 10 percent reduced risk of atrial fibrillation. The findings were independent of factors including age, sex, financial status, regular exercise, alcohol consumption and body mass index.

Other studies have shown that poor oral hygiene leads to bacteria in the blood, causing inflammation in the body. This increases the risk of an irregular beat and heart failure.

The number of births in Japan last year fell below 700,000 for the first time on record, government data showed Wednesday.

The fast-ageing nation welcomed 686,061 newborns in 2024 -- 41,227 fewer than in 2023, the data showed. It was the lowest figure since records began in 1899.

Japan has the world's second-oldest population after tiny Monaco, according to the World Bank.

Prime Minister Shigeru Ishiba has called the situation a "quiet emergency", pledging family-friendly measures like more flexible working hours to try and reverse the trend.

Wednesday's health ministry data showed that Japan's total fertility rate -- the average number of children a woman is expected to have -- also fell to a record low of 1.15.

The ministry said Japan saw 1.6 million deaths in 2024, up 1.9 percent from a year earlier.

Ishiba has called for the revitalization of rural regions, where shrinking elderly villages are becoming increasingly isolated.

In more than 20,000 communities in Japan, the majority of residents are aged 65 and above, according to the internal affairs ministry.

The country of 123 million people is also facing increasingly severe worker shortages as its population ages, not helped by relatively strict immigration rules.

In neighboring South Korea, the fertility rate in 2024 was even lower than Japan's, at 0.75 -- remaining one of the world's lowest but marking a small rise from the previous year on the back of a rise in marriages.
