Cycling and exercise good for the heart; lack of sleep is bad
People who cycle and exercise regularly have less chances of getting heart and vascular diseases, whereas a lack of sleep raises such chances. This is reported in two publications: from the National Institute for Public Health and the Environment (RIVM), and Wageningen University.

Hoevenaar-Blom published the results last month in the European Journal of Cardiovascular Prevention and Rehabilitation. The research work is part of the MORGEN study which also led to the publication of another article in the magazine Sleep. Hoevenaar-Blom reported in the latter that people who sleep less than six hours each night over a long period and wake up in the morning without having enough rest will have 63 percent more probability of getting heart and vascular diseases.
