Unfortunately, there is no way to train your body to function well on less sleep. Getting insufficient sleep on a regular basis can lead to health conditions, accidents, and poor performance in both school and athletics. Health Conditions Not getting enough sleep can have a negative effect on a person’s health in many different ways. People who do not get enough sleep are more likely to get colds and other types of infections.
