Stress is killing us. Not only does it increase the risk of heart disease by 40 percent, it boosts your risk of heart attack by 25 percent and stroke by 50 percent, according to The American Institute of Stress. While we all experience stress here and there, particularly when it comes to situations at work, some people are more prone to depression and anxiety when they don't learn how to de-stress in between.

In fact, stress has an ongoing negative reaction, especially for those who can't "let go" of their stress from day to day, resulting in not only psychological problems but physical ones as well. Amazingly, simply getting good, quality sleep--and enough of it--can help us all deal with stress much better. As an entrepreneur, it's normal for your mood to fluctuate with the highs and lows of your business, but consistent stress can lead to irritability, impatience, chronic moodiness, and poor judgment.

Let's take a look at these six guaranteed ways to be less stressed.

1. Non-toxic sleep

Your health and wellness is impacted by the quality of sleep you get each night. If you're not getting the Z's you need, it could very well be the mattress you're sleeping on that's to blame. As such, it's important to sleep on one that provides maximum comfort and support but that does not expose you to dangerous toxins, according to Intellibed. Illness and disease can result from exposure to toxic off-gassing stemming from synthetic materials and flame retardants that are contained in many of the traditional mattresses on the market today. Choosing a 100 percent non-toxic mattress will provide the most health benefits for you and help you get the restorative sleep you need to combat stress.

2. Relax.

Sure, this is often easier said than done, but if you don't carve out some "me" time every day, stress can easily overpower you. Sign up for a yoga class a few times a week, perhaps after work to calm down before heading home, providing a buffer between your work and home life. Is there a hobby you've always wanted to try, such as gardening, photography, or hiking? A hobby can be good for the soul and help you realign your priorities.

3. Get professional help.

Sometimes you can't do it all on your own. With increasing demands at work making you stressed out, you may feel as though you just can't stop feeling anxious and on edge. Reducing the tension through professional help to relieve your symptoms from a qualified psychologist is a wise idea, advises PsychCentral.

4. Get social.

You have to be with your coworkers all day, every day, in the trenches together. This is the greatest support system you have because everyone is in the same boat. Instead of complaining and getting nowhere, turn that around and hang out with those co-workers who are supportive of each other, fun to be with, and calm. This moral support you get will go a long way towards helping you cope with everyday work situations.

5. Take a vacation.

Remember what a vacation is? If you can't, it's time to take one! CNBC says unused worker vacation time is at a 40-year high. Taking vacation days can help lead to better performance reviews, lower employee turnover, increased productivity, and happier employees.

6. Reconnect with yourself.

If you've been having a hard time at work with a particular project, colleague, or boss and can't seem to get back on track, it's time for some self-reflection. You need to get re-aligned with what you loved about your job and occupation in the first place, regaining the connection to a meaningful daily work experience.
