I think this is a useful page and will give you some ideas of some possible products. I will give a short explanation of the concept of stress. The concept of stress is that there are two parts of your body, the emotional and the cognitive.
When we are stressed, we need to respond to this stress. A person who is stressed needs to perform an act, because it will help him to be calm and relax. When you are feeling stressed, your brain is not functioning well. Your cognitive function decreases. When you feel like you cannot do anything, you might think, "My life is not worth living." That's why you feel very stressed. If your stress can go up and down, it will not make you happy.
You can also think, "I don't deserve life" if you are in a bad mood, or "I deserve death" if you are really upset. Stress and mood disorders are associated with depression, anxiety, sleep disorders, and substance abuse.
Many people don't know about the importance of good sleep and exercise, especially during the day. Sleep can be a critical part of a healthy lifestyle. One study showed that people with stress disorders slept worse, slept less, and suffered from other symptoms, even if they slept well, on average, for a period of one week. This is true for anyone.
