The immune system is the body’s protection against viruses and infections. When bacteria enters the body, the immune system will, if healthy, combat the bacteria in order to stop it from spreading throughout the body. When the body becomes ill, immunity is weakened and the body has to work harder in order to combat the bacteria.
There are steps one can take in order to boost the immune system and keep it healthy. Most of these steps take the form of following a healthy diet and eliminating harmful substances that weaken immunity. A great way of combating infection and illness is to take regular exercise. Exercising for at least 20 minutes a day, three times a week, can help keep your immunity high. Exercise also boosts the circulation system and reduces the risk of certain diseases. Exercise does not have to be a workout in the gym. Any type of exercise that gets the body sweating, flushing out harmful toxins, will count.
One of the major threats to the immune system is smoking. Many smokers find themselves with constant colds and viral infections. Smoking is also widely known to be a contributory factor in a wealth of other diseases and illnesses.
The type of food that you eat also contributes to the health of your immune system. Eating plenty of fresh fruit and vegetables every day is a must to keep the body in top shape. Eating fast food only slows the body’s metabolism and contributes to weight gain. Any foods that are rich in vitamins and minerals can help keep you healthy. Older people and pregnant women will especially benefit from eating foods that are rich in essential nutrients.
Cutting down on drinks with a high caffeine content is also a good idea. Drinking plenty of water helps flush harmful toxins from the body. Fresh fruit juices also provide vitamins, and there are also plenty of herbal teas that can be a great substitute for regular tea and coffee.
A big factor in keeping the immune system healthy is the amount of quality sleep that you achieve each night. During the sleep cycles, the body repairs itself in order to remain fighting fit. Sleep is also a great stress reducer. When the body is stressed, the immune system is weakened. Different people need varying amounts of sleep, but obtaining eight hours per night should be enough to keep the body healthy.
Although they can be used to fight infection, many medicines and drugs can weaken the body’s defense system. A doctor should always be consulted before taking any medication. Similarly, recreational drugs do much to harm the body’s defense system and should be avoided.
