Short or excessive sleep and daytime napping may increase the risk of developing hypertension and other cardiovascular diseases, researchers from the Australian Baker Heart and Diabetes Institute have found.
Scientists examined data on more than 350,000 people. The information obtained was then correlated according to age, gender, body mass index (BMI) and circadian rhythm disorders. The experts concluded that sleep disorders or working through the night were associated with high blood pressure in all age groups in both men and women. Participants who worked night shifts and slept less than five to six hours per night were at greatest risk. There was also a significant correlation in the group with mixed work schedules.
Too much sleep also had a negative impact on circadian rhythms. Naturally, short sleep and shift work had the most devastating effect on blood pressure.
In August, researchers from York University in the Canadian city of Toronto showed a link between shift work and memory. According to their data, people who work night shifts are more prone to cognitive impairment, including memory loss. /BГNES
