Study: Simple Habits May Reduce the Risk of Amyotrophic Lateral Sclerosis

A preliminary study by the American Academy of Neurology suggests that early rising and regular physical activity are associated with a reduced risk of developing amyotrophic lateral sclerosis (ALS), also known as Amyotrophic Lateral Sclerosis. This neurological disorder leads to the progressive loss of motor and respiratory functions.

According to the study, which followed 500,000 participants over a period of 14 years, the risk of developing the disease decreased by 20% among individuals with a morning chronotype and by 26% among those with the highest levels of physical activity. Researchers recorded 386 cases among 314,170 highly active individuals, compared to 107 cases among 70,946 participants with the lowest activity levels.

Regarding sleep habits, sleeping between six and eight hours per night was associated with a lower risk compared to shorter or longer durations. The protective effect of a morning chronotype remained significant even after adjusting for factors such as age, sex, and body mass index. The study relied on metabolic equivalent (MET) units to measure the intensity of physical exertion.

However, the researchers emphasize that these findings demonstrate a statistical association and do not establish a direct causal link. They call for further research, particularly given the study’s limitations, including a sample composed of 95% white participants.
