Are you proud that you’re awake at all hours and still functioning（起作用，工作）normally? It may be costing you.

Some studies show that people who get more sleep get fewer colds, tend to maintain a healthier weight and have a smaller chance of coming down with heart disease and diabetes（糖尿病）. But if you’re uninterested in the health benefits of sleep, you may need to watch out for your carrier.

If you aren’t sleeping, you’re putting your career at risk. Nitun Verma, medical director for the Washington Township Center for Sleep Disorders in Fremont, California, sees this a lot. He works with many professionals in Silicon Valley and says there are two typical groups of patients who tend to come into his office.

“The first group is the professional at a larger, more established company, usually in their 40s to 50s,” Verma says, adding that these people often feel sleepy at work, which worsens as the afternoon progresses. “They have a fear that some younger, more energetic person is going to take their job or their promotion.”

On the other hands, people in their 20s and 30s suffer from sleepless nights, too. Verma tells us they have a more active social and professional night life, advancing their lives and careers, and often only sleep four to five hours a night. A 25-year-old patient had been disciplined（训练）by his supervisor for falling asleep at his desk. “I was standing in my boss’s cubicle and being chewed out for falling to sleep. As this was occurring, I fell asleep and crashed through the cubicle wall,” the patient said.
