With increasing age, our immune system weakening is a natural process, which is called immunosenescence. After 50, its effect becomes even more clearly visible. Due to a weak immune system, the body fails to fight viruses and bacteria, which increases the risk of diseases like flu, shingles and pneumonia. However, the good news is that you can strengthen your immune system by adopting some healthy habits. Everyone advises regular exercise, balanced diet, stress management and getting enough sleep, but let us explain all these things to you today with the help of a doctor, so that you will be able to keep yourself fit even after the age of 50 (Stay fit after 50) and looking at your health, everyone will try to know the secret of this fitness.

1) Drink plenty of water,

Drinking enough water is something that is often overlooked but is vital for a healthy immune system. Dehydration can negatively impact your body's ability to fight off infections by impairing the functioning of immune cells and weakening the body's defense mechanism. As we age, we lose the feeling of thirst, making us more likely to become dehydrated. So make sure you're consuming enough liquid foods throughout the day, including water, herbal teas, and fruits and vegetables. By keeping your body hydrated, you're helping with the absorption of nutrients, elimination of waste, and overall immune system function.

2) Nutrient-Rich Diet

Nutrition is extremely important to keep our immunity strong. As we age, our body is not able to absorb nutrients as well. Therefore, we should take a diet rich in nutrients like fruits, vegetables, grains and lean proteins. Probiotics also help in keeping the digestive system healthy which is very important for the immune system. Nutrients like vitamins C and E, zinc and selenium act as antioxidants and protect the body cells from damage.

3) Keep getting necessary vaccinations

Vaccination is one of the most effective ways to boost immunity or prevent infections that occur as we grow older. Over time, our immunity weakens, making the elderly more susceptible to diseases like shingles, pneumonia, and the flu.

Vaccines help our bodies make antibodies that help fight these infections. For example, the shingles vaccine is especially important for people over the age of 50 because childhood chicken pox can reactivate and cause a painful shingles infection.

4) Getting enough sleep is important

Getting good sleep is very important for our body. It not only repairs and regenerates our body, but also keeps our immunity strong. Not getting enough sleep weakens our immunity, due to which we become victims of various types of infections. Actually, during sleep, our body produces a special type of protein called cytokines which helps in fighting infection and inflammation. Let us tell you, the production of cytokines slows down on getting less sleep, due to which our ability to fight diseases becomes weak. Therefore, we should aim to get 7-9 hours of good sleep every night so that our immunity power always remains good.

5) Be physically active

You must have heard that exercising is very good for health, but do you know that exercising not only controls our weight but also strengthens our muscles and increases the ability to fight diseases.

When we exercise regularly, the blood circulation in our body also improves. This blood contains some special cells that protect our body from diseases. When the blood flow improves, these cells are able to move easily throughout the body and are ready to fight any germs.

Exercising also reduces a type of inflammation in our body. This inflammation reduces our body's ability to fight diseases as we grow older. Therefore, by doing regular exercise we can reduce this inflammation and stay healthy.
