5 good habits that will keep your immune system strong
7. September, 2022
Get enough sleep
Sleep and immunity are closely tied. In fact, inadequate or poor quality sleep is linked to a higher susceptibility to sickness. Getting adequate rest may strengthen your natural immunity. Also, you may sleep more when sick to allow your immune system to better fight the illness. Adults should aim to get 7 or more hours of sleep each night, while teens need 8–10 hours and younger children and infants up to 14 hours.
If you’re having trouble sleeping, try limiting screen time for an hour before bed, as the blue light emitted from your phone, TV, and computer may disrupt your circadian rhythm, or your body’s natural wake-sleep cycle. Other sleep hygiene tips include sleeping in a completely dark room or using a sleep mask, going to bed at the same time every night, and exercising regularly.
Hydration doesn’t necessarily protect you from germs and viruses, but preventing dehydration is important to your overall health. Dehydration can cause headaches and hinder your physical performance, focus, mood, digestion, and heart and kidney function. These complications can increase your susceptibility to illness.
To prevent dehydration, you should drink enough fluid daily to make your urine pale yellow. Water is recommended because it’s free of calories, additives, and sugar. As a general guideline, you should drink when you’re thirsty and stop when you’re no longer thirsty.
Manage your stress levels
Relieving stress and anxiety is key to immune health. Long-term stress promotes inflammation, as well as imbalances in immune cell function.
Activities that may help you manage your stress include meditation, exercise, journaling, yoga, and other mindfulness practices. You may also benefit from seeing a licensed counselor or therapist, whether virtually or in person.
Engage in moderate exercise
Moderate exercise can reduce inflammation and promote the healthy turnover of immune cells. Jogging, biking, walking, swimming, and hiking are great options.
Eat nutrient tense foods
Feeding your body certain foods may help keep your immune system strong. Nutrients impact immune cells causing changes in their function or may exert effects via changes in the gut microbiome. For best results have a nutritious diet. Whole plant foods like fruits, vegetables, nuts, seeds, and legumes are rich in nutrients and antioxidants that may give you an upper hand against harmful pathogens. The antioxidants in these foods help decrease inflammation by combatting unstable compounds called free radicals, which can cause inflammation when they build up in your body in high levels.
Some of the top immune-boosting vitamins include vitamin A, vitamin B6, vitamin C, vitamin D3 and vitamin E. Zinc, iron and selenium help enhance immune function, protect against cell damage and fight infection. Healthy fats like olive oil and omega-3s are highly anti-inflammatory. Since chronic inflammation can suppress your immune system, these fats may naturally combat illnesses.
Gut health and immunity are deeply interconnected. Fermented foods and probiotics may bolster your immune system by helping it identify and target harmful pathogens.
