Increased risk of hemorrhagic stroke in case of irregular supper hours

According to a study conducted in Japan, eating dinner at any time increases the risk of hemorrhagic stroke. Researchers believe that the best thing to do every night is to have supper at regular times and if possible before 8 p.m.

What is a hemorrhagic stroke?

Hemorrhagic stroke is one of two known types of stroke and occurs as a result of intracerebral hemorrhage. This usually happens in the event of a rupture of an artery (or a blood vessel) in the brain. This is because the interruption of blood flow can lead to the death of brain cells and cause brain damage. Among the common causes of hemorrhagic stroke, we find high blood pressure, which weakens the arteries over the years.

Also, remember that hemorrhagic stroke represents about 15% of cases and is therefore rarer than ischemic stroke , the latter occurring when blood cannot properly reach a part of the brain due to a blockage in the blood vessels.

Increased risk of hemorrhagic stroke in case of irregular supper hours

A study over two decades

In September 2021, a Japanese study published in the journal Nutrients linked dinner hours to increased risk of hemorrhagic stroke. The researchers wanted to carry out this work because, in their opinion, there is a lack of data concerning the role of supper time in the development of cardiovascular disease. No less than 28,625 men and 43,213 women participated in this study. These individuals, all in good cardiovascular health, joined three different groups. The members of the first group had to dine before 8 p.m., those of the second group after 8 p.m. and those of the last group at very irregular hours.

During nearly two decades of tracking, scientists have found no less than 4,706 deaths following the onset of cardiovascular disease. Their conclusion is as follows:an irregular dinner schedule has a strong link with a greater risk of hemorrhagic stroke compared to eating dinner before 8 p.m. On the other hand, there is no significant link between dinner time and the risk of mortality for other types of stroke, coronary artery disease or cardiovascular pathologies.

“In this prospective cohort study, adopting an irregular supper time versus having dinner before 8:00 p.m. was associated with an increased risk of death from hemorrhagic stroke. We also observed a positive association between irregular supper time and stroke risk in people with a BMI of 23.0 to 24.9 kg/m2″, the researchers said.
