You don’t have to do some crazy diet in order to get healthy. There are other, safer things you can do to get and stay healthy. Crash diets can be very damaging for a person’s system and health. Take these few simple actions to help you stay healthy.

Try to get in at least 30 minutes of cardio every day. Even just going on a walk for 30 minutes a day is enough to help keep fat and weight off that people normally get from inactivity. If you don’t normally work out, nor do a lot of activities that require you to keep moving and burn calories, start off with maybe 15 minutes or cardio and work your way to 30 minutes. There are different types of cardio work outs that are either high or low impact. If you feel that simply walking isn’t enough to get your heart pumping and to get you sweating, try staying with low impact activities. Low impact work outs would be walking, swimming, elliptical trainers, skating, and stationary bikes. High impact activities include basketball, football, hockey, karate, running, and anything that has intense and/or frequent wear and tear on weight-bearing joints. Listen to your body when working out, if you aren’t used to physical activity, try to keep to low impact sports. High impact sports can be hard on joints, like your hips, knees, and ankles.

Another thing you can do is watch your calorie intake. You want to make sure that you are burning more calories than what you are eating. Of course, depending on home much weight you want to lose, or if you just want to maintain your weight, you will need to check you BMI, body mass index, to find out what your calorie intake should be. Also, you can use BMI to see if you are overweight, or even underweight. People who are overweight are more likely to develop heart disease, high blood pressure, sleep apnea, and type 2 diabetes.

Something else you can do to keep healthy is try to get regular sleep. You want to make sure you get between 7 and 9 hours of sleep. Getting the proper amount of sleep can help you stay more alert, and help reduce stress. Getting the proper amount of sleep can also keep your heart healthy by reducing stress and inflammation on your cardio vascular system. Sleep can also keep blood pressure and cholesterol levels low, which will also help your heart.

Keeping your body and mind healthy is essential to living a long and hopefully happy life. It doesn’t matter if you are trying to lose weight, or simply just trying to get healthier, there are many things you can do to change your life for the good. Of course with anything that has to do with your health, talk to your doctor. You and your doctor can go over different diets, work out plans, and other changes that can help you live a healthier life.

Immune system diseases are one of the deadliest types of diseases given to man. Among immune system diseases are special contagious microorganisms, which are highly evolved to disable our body defenses. They aim to only destroy one specific component of our immune system functioning. It’s as if they know our bodies better than ourselves. By finding our loopholes, these microorganisms can compromises our body and we lose the fight. Sometimes they even cause autoimmunity. Let’s examine some scenarios where the body fails to fend off immune system diseases, and some tips to prevent immune system diseases.

The body has evolved several components that all work together to fight off disease. If one component malfunctions, the system may fail completely. Alternatively, it may become corrupted, hijacked, and manipulated by pathogens. Sometimes, the body can mistake “friends” as “enemies” and start attacking other cells in the body. There are 3 types of categories for immune system diseases. The first wide category is called immunodeficiency, where the bodily defense systems become inactive due to age, nutrition, or acquisition, as introduce by foreign pathogens such as HIV. Another category is autoimmunity, where the body fails to distinguish between itself and foreign pathogens. As a consequence, it often attacks itself, resulting in our own self destruction. Finally, there is hypersensitivity; the body overreacts with a massive response, assuring that its own tissues become damaged. This condition is characterized by reactions due to allergies. This is the mechanism of why anaphylactic reactions occur.

Immune system diseases thus present a set of many complications that are varied, as well as narrow at the same time. The best way to avoid the pitfalls of ill health and immune system disease is through best practices for disease prevention, as well as early detection. Early detection allows us to take advantage of the modern day developments in biological sciences.

However, there is a catch to early detection for the body itself. There is an effect called the original antigenic sin problem and refers to the secondary infection. After an initial primary infection, the body develops a memory for the pathogen, usually allowing the body to fend off infection from the same pathogen easier. This is well known and documented; for example, this is why most people get chickenpox only once. The body actually bases all future defenses on the first exposure to chickenpox. Hence, if the first chickenpox is weak, future strong strains of chickenpox may overtake the body’s response.

Thus, in its haste, the body itself may get stuck with only providing a weak response. One example is HIV, a tricky beast. As a virus, it has the propensity to modify its outer membranes. It can trick the body into learning a weaker immune response, and the body’s immune response is trapped. This was first written by McMichael in the Nature article, “The original sin of killer T cells” (Volume 394).

The best way to prepare for an infection is to plan to never catch it at all. By adopting the right lifestyle, with exercise, good sleep, and a healthy diet, you can help prevent the nightmare of immune system diseases.
