Night owls- people who stay up late and have difficulty waking up in the morning- are more likely to die early than larks, who go to bed and wake up early. Night owls also had more health problems: twice the risk for psychological disorders; 30% higher chance of having diabetes; 25% increased risk of neurological problems; 23% greater risk of gastrointestinal disorders; and 22% per cent increased the risk of respiratory disease. Being a night owl could interfere with our biological clock and negatively impact our health. It could be psychological stress, eating at the wrong time, not exercising enough not sleeping enough, being awake at night by yourself, maybe drugs or alcohol use. There are a whole variety of unhealthy behaviours related to being up late in the dark by yourself,” the study author noted. The study suggested that the night owls should try to go bed early, stick to a regular bedtime, avoid using smartphones late night, get exposure to natural light in the morning and follow an overall healthy lifestyle.
