Exams and extracurricular activities, classes and co-workers, studying and sleeping: all different aspects of daily college life linked by one common problem -- stress.

"It seems like all classes have everything due at the same time and tests are really close together," Michelle Ulsh (junior-health care administration) said. "When I'm overly stressed I drink a lot of coffee and don't sleep much. ... Stress is a big part of my life."

Stress is scientifically proven to be a part of everyone's life. Humans' hormones could not react effectively without it. People could not deal with hunger, danger, infection, extreme temperatures and the challenges of growing up without stress.

There are positive aspects of moderate amounts of stress. It provides stimulation and makes people more productive and perceptive. It also keeps people aware of danger.

Most college students seem to experience more than what is considered a moderate amount of stress. School, work, jobs, clubs and friends might not leave time for much of anything else. Stress has both physical and psychological effects that can seriously affect a person's health.

If someone is really stressed out, it might be evident by his or her physical appearance.

"Common symptoms include dry skin, lack of drive, sexual changes and differences in eating habits," said Stefanie Lewis, RN, from Centre Medical and Surgical Associates in Bellefonte. "Most people just want to stay in bed."

Sallow skin, acne and body odor are all stressed induced. Because stress weakens the immune system, it makes us more susceptible to infectious diseases, colds, cold sores, hives, eczema, psoriasis and rosacea.

Healthy sleep patterns might be interrupted, and stress can contribute to weight gain or loss, hair loss, and ulcers.

There are both short- and long-term effects of stress.

"Short-term effects include elevated blood pressure, poor immune system and decreased coping mechanisms. Long-term effects may include severe depression and weight fluctuation," Lewis said.

Stress not only takes its toll on people's bodies, but also their minds. Psychological effects may include anxiety, nervousness, poor concentration, depression, anger and jealousy. Tiredness may lead to irritability, making it difficult to get along with others. Stress also exacerbates fears and phobias, obsessions and suspicions.

"I do notice physical changes when I'm real stressed out," said Chris Strunk (senior-mechanical engineering). "Just everything put together that I need to do for school is the most stressful aspect of my life."

Most students say the evening is when they experience the greatest amount of stress.

"I do most of my work at night because I have gaps in between classes that don't allow enough time to get all the work done. Trying to get everything together for the next day is stressful," Jackie Hanna (freshman-political science) said.

Although some people thrive under stress, others buckle. Experts say a proven way to reduce stress is to take time out to do enjoyable activities.

"I listen to music, go to the gym, or just watch TV," Hanna said. "Most of the time I'm really tired and just sleep."

Lewis said she does not advise taking medication to deal with stress.

"The key is to find an activity that relaxes you. We suggest exercising or talking to someone you trust, such as a family member, friend or pastor. Anything that you do that helps you vent frustration will help," Lewis said.
