A new study finds that a consistent sleep schedule can prevent mental and physical aliments.

The American Psychological Association looked at data from 55,000 people over five decades and found that when people had their sleep disrupted, they reported fewer positive emotions.

Findings also showed symptoms of anxiety and depression worsened after a poor night's sleep, even for people who do not suffer from either.

Researchers say it took as little as staying up an hour or two later than normal for participants to feel the negative impact.

Doctors say poor sleep can contribute to diabetes, obesity and heart disease.

It can also lead to high blood pressure, fatigue and a non-productive day.

The Centers for Disease Control and Prevention says adults need at least seven hours of sleep every night to be healthy.

Ways to get a good night sleep include making your bedroom a dark, quiet and cool space, power down electronics at 30 minutes before bedtime and exercise daily, but not within 3 hours of going to sleep.
