Learn to Relax and Sleep Like a Baby

Medical Author: Melissa Conrad Stöppler, MD
Medical Editor: Dennis Lee, MD

Get tips on how to relax, lower your stress, and sleep like a baby.Think about how easy it is for a baby or small child to fall asleep. We're born with the instinct to relax and sleep when our bodies or minds need a break. Over the years, it becomes necessary to control and even suppress these natural urges to rest, since we must remain alert as we attend school, learn professions, go to work, or care for a family. Many people spend years conditioning themselves to perform well despite feelings of tiredness. While no one would argue that suppressing tiredness can be a necessary skill, it can impair our ability to actually "let go" and relax when we do find the time.

Relaxation is also a uniquely individual activity. Napping or just doing nothing might be your idea of relaxation, but this amount of inactivity might drive someone else crazy. Others may relax by participating in sports or undertaking physical challenges, but some people would find these activities stressful. Whatever your idea of relaxation, the following tips can help you retrain and regain some of those lost relaxation skills...

Heart disease and stress introduction

Are stress and heart disease related? Does stress increase the risk of heart disease? Stress is a normal part of life. But if left unmanaged, stress can lead to emotional, psychological, and even physical problems, including heart disease, high blood pressure, chest pains, or irregular heart beats.

How Does Stress Increase the Risk for Heart Disease?

Medical researchers aren't sure exactly how stress increases the risk of heart disease. Stress itself might be a risk factor, or it could be that high levels of stress make other risk factors (such as high cholesterol or high blood pressure) worse. For example, if you are under stress, your blood pressure goes up, you may overeat, you may exercise less, and you may be more likely to smoke.

If stress itself is a risk factor for heart disease, it could be because chronic stress exposes your body to unhealthy, persistently elevated levels of stress hormones like adrenaline and cortisol. Studies also link stress to changes in the way blood clots, which increases the risk of heart attack.

Does Stress Affect Everyone the Same?

No. People respond in different ways to events and situations. One person may find an event joyful and gratifying, but another person may find the same event miserable and frustrating. Sometimes, people may handle stress in ways that make bad situations worse by reacting with feelings of anger, guilt, fear, hostility, anxiety, and moodiness. Others may face life's challenges with ease.

What Causes Stress?

Stress can be caused by a physical or emotional change, or a change in your environment that requires you to adjust or respond. Things that make you feel stressed are called "stressors."

Stressors can be minor hassles, major lifestyle changes, or a combination of both. Being able to identify stressors in your life and releasing the tension they cause are the keys to managing stress.

Below are some common stressors that can affect people at all stages of life.

  • Illness, either personal or of a family member or friend.
  • Death of a friend or loved one.
  • Problems in a personal relationship.
  • Work overload.
  • Starting a new job.
  • Unemployment.
  • Retirement.
  • Pregnancy.
  • Crowds.
  • Relocation.
  • Daily hassles.
  • Legal problems.
  • Financial concerns.
  • Perfectionism.

Stress and Heart Disease

What is stress?

Stress is simply a fact of nature -- forces from the outside world affecting the individual. The individual responds to stress in ways that affect the individual as well as their environment. Hence, all living creatures are in a constant interchange with their surroundings (the ecosystem), both physically and behaviorally. This interplay of forces, or energy, is of course present in the relationships between all matter in the universe, whether it is living (animate) or not living (inanimate). However, there are critical differences in how different living creatures relate to their environment. These differences have far-reaching consequences for survival. Because of the overabundance of stress in our modern lives, we usually think of stress as a negative experience, but from a biological point of view, stress can be a neutral, negative, or positive experience.
