Stress is a major cause of poor health in many people. Stress can have a negative impact on the body's immune, reproductive, digestive, and cardiovascular systems. Unchecked, stress can lead to many ailments such as heart disease, depression, and obesity. In addition to the obvious negative effects, stress can also interfere with a person's sexual desire.
The body's response and stress management is managed by the autonomic system. Normaly, the body produces different levels of hormones throughout each day. The body will produce more stress hormones adrenalin (and cortisol) during stressful situations. These hormones increase blood sugar levels and the production of fatty acids in the liver, muscles and brain. When adrenalin is released, blood vessels in the arms or legs dilate to increase heartbeat.
Another important factor in the effects of stress on the body is the interaction between the immune system and the hypothalamic-pituitary-adrenal (HPA) axis. Cortisol is a hormone that acts in the role of a messenger during stressful events. Glucocorticoids, also known as "stresshormones", are vital in the regulation and maintenance of the immune response.
The mood of a person can also be affected in part by the microbiome. Stress is related to changes in the gut's bacterial population, which can influence mood.
One recent study suggests that a healthy diet can help alleviate stress. Researchers took a group of people and measured their diets. They also asked them to fill out several questionnaires. Also, they were assessed for self efficacy. This is the ability to believe that one can deal with difficult situations. High self-efficacy scores resulted in lower stress scores.
Stress can influence sodium levels in the body, researchers found. The stressors who had higher levels of stress reported a greater increase in sodium intake. Sodium can increase blood pressure which can lead to physiological stress reactions that are worsened.
Multiple studies have shown that stress has been linked to changes within the brain's ability to process serotonin, a neurotransmitter. The regulation of a number of physiological functions is controlled by serotonin.
Research also suggests that stress can increase appetite. People with more stress also tends to eat more fat and salt. This has been linked to mental disorders like depression and PTSD.
Relaxation techniques have many benefits. They are good for your physical health and can help you deal with stress. Studies have shown that people who do stress-relieving activity report higher levels of happiness. Relaxation techniques can also be used to reduce muscle tension, improve daily function, and help with chronic pain.
Future studies will focus on the global relationship between diet and health. The importance of multidisciplinary research and clinical trials will be paramount. Future research should also focus on the effects of dietary interventions on large populations.

Exercise: Good and bad for immunity?
Exercise is good to your immune system. When you exercise, your body produces white blood cells which fight off infections. You also get rid toxins. Exercise is a great way to prevent diseases such as cancer and heart disease. It reduces stress.
But too much exercise can damage your immune system. If you work out too hard, your muscles become sore. This can cause inflammation and swelling. Your body then needs to make more antibodies in order to fight infection. These extra antibodies can lead to allergies or autoimmune disorders.
So, don't overdo it!
Is being cold good for your immune system.
Cold weather can cause a decline in your immune system. Your body makes less white blood cell to fight infection. However, being cold also makes you feel better because your body releases endorphins into your brain which reduce pain.
How often should I exercise
For a healthy lifestyle, exercise is vital. There is no set time limit for exercising. The key is to find something that you enjoy and to stick with it.
If you exercise three times a week then aim for 20-30 mins of moderate intensity. Moderate intensity means that you will still be working hard even after your workout is over. This type of exercise burns approximately 300 calories.
For those who prefer to walk, you can go for 10-minute walks four times a week. Walking is low in impact and easy for your joints.
Jogging for 15 minutes three days a week is a good option if you prefer to run. Running is an excellent way to lose weight and tone your muscles.
You can start slow if you are new to exercise. Start with just 5 minutes of cardio a few times a week. Gradually increase duration until you achieve your goal.
What's the difference between a virus & a bacterium?
A virus is an organism microscopic that can't reproduce outside its host cells. A bacterium, a single-celled organism, reproduces by splitting into two. Viruses measure only 20 nanometers in diameter, but bacteria is up to 1 millimeter in size.
Viruses can be spread by contact with bodily fluids containing infected substances, such as saliva, urine and semen. Bacteria are usually spread through direct contact with contaminated objects or surfaces.
Viral infections can be transmitted through skin cuts, scrapes and bites. They can also penetrate the nose, lips, eyes and ears, vagina,rectum, or anus.
Bacteria can be introduced to our bodies by cuts, scrapes or burns. They can also be introduced to our bodies by food, water and soil.
Both bacteria and viruses cause illness. However, viruses cannot reproduce within their hosts. They can only infect living cells and cause illness.
Bacteria can multiply within their hosts and cause illness. They can invade other areas of the body. That's why we need antibiotics to kill them.

What does "vitamin" actually mean?
Vitamins are organic compounds that can be found in foods. Vitamins aid us in absorbing nutrients from the food we eat. Vitamins are not made by the body, so they must be obtained through food.
There are two types of vitamins: water soluble and fat soluble. Water-soluble vitamins dissolve readily in water. Some examples include vitamin C,B1 and B2 vitamins (thiamine), B2 and riboflavin, B3 and niacin, B6 vitamins (pyridoxine), B6 vitamins (niacin), folic acids, biotin, pantothenic acids, and Choline. The liver and fat soluble vitamins are stored in fatty tissue. You can find vitamin D, E K, A and beta carotene as examples.
Vitamins can be classified by their biological activity. There are eight major groups of vitamins:
-
A - Vital for healthy growth.
-
C – essential for proper nerve function.
-
D - Vital for healthy bones and teeth
-
E is needed for good reproduction and vision.
-
K - Essential for healthy muscles and nerves.
-
P - essential for strong bones, teeth and tendons
-
Q – aids digestion and absorption.
-
R is required for the production of red blood cells.
The recommended daily intake (RDA), of vitamins varies with age, gender and physical conditions. RDA values are set by the U.S. Food and Drug Administration (FDA).
For adults aged 19 and older, the RDA for vitamin B is 400 micrograms daily. Pregnant women require 600 micrograms daily to support fetal development. Children ages 1-8 require 900 micrograms per day. Infants below one year of age need 700 micrograms daily. But, between 9 months to 12 months of age, the amount drops to 500micrograms per days.
Children ages 1-18years who are obese need 800 micrograms per day while those who are overweight need 1000 micrograms per day and children who are underweight need 1200 micrograms per day to meet their nutritional needs.
Children aged 4-8 years old who have been diagnosed as having anemia require 2200 micrograms of vitamin C per day.
2000 micrograms per person is necessary for general health. Due to their increased nutrient needs, pregnant and breastfeeding women need 3000 micrograms daily.
1500 micrograms are required daily by adults over 70 because they lose approximately 10% of their muscle each decade.
Women who are pregnant, nursing or breastfeeding need more than the RDA. Pregnant women need 4000 micrograms per dayduring pregnancy and 2500 micrograms per day after delivery. Breastfeeding mothers need 5000 micrograms per day when breast milk is being produced.
