Top 3 Immune Hacks for 2021

Top 3 Immune Hacks for 2021

Keeping your immune system strong has never been more critical. For 2021, I recommend three health hacks that will help enhance your immunity:

1. Get plenty of quality sleep.
2. Exercise regularly.
3. Take one of the world’s most powerful antioxidants, astaxanthin, from BioAstin Hawaiian Astaxanthin.+

Let’s start with sleep. Chances are you’re not getting enough of it. In fact, according to the CDC, an estimated 50 to 70 million adults in the United States have chronic sleep and wakefulness disorders. They don’t get the 7 to 8 hours of good sleep they need each night to keep their immune system in top working order.1 A consistent and adequate sleep pattern strengthens the immune system. Irregular or inadequate sleep, however, depresses immunity and can leave you vulnerable to illness.

Why is sleep so important for immunity? It’s because your body uses the time when you’re asleep to direct energy toward strengthening your adaptive immune system. Adaptive immunity is how your body learns to fight off an infection by producing antibodies to pathogens.

Once the infection is over, your immune system cells remember the pathogen and respond to it quickly the next time it invades your body. Sleep helps your immune system consolidate its memory of the attacker and improves your ability to recognize and respond to it.2

The next step for building your immunity is regular exercise. Being active makes you breathe harder and raises your body temperature. Breathing harder helps flush bacteria and viruses out of your lungs and airways, reducing the chances that they’ll infect you with a cold, flu, or other illness. Raising your body temperature may also keep pathogens from growing, the same way your body uses fever to fight off infection. Physical activity also modulates your immune system by increasing your production of cytokines (chemical messengers important for coordinating the immune response) and increasing the number and circulation of infection-fighting immune cells. Regular exercise is particularly valuable for helping the immune system fight off respiratory viruses.3

Aim for at least 30 minutes of physical activity every day—the kind that makes you breathe harder and your heartbeat faster. It doesn’t really matter what form of exercise you choose to do—cardio, strength, or flexibility—so long as you do it consistently, and correctly, most days of the week. A brisk walk or working out to an online video are great, but even vacuuming the house counts.

Finally, build up your immune system by getting plenty of antioxidants from your food and from BioAstin Hawaiian Astaxanthin supplements.+ When your immune system gets called into action, it produces many damaging free radicals as an inevitable byproduct. These unstable molecules steal electrons from other molecules, causing damage to your cells as they do. Antioxidants neutralize the free radicals by acting as an off switch, shutting off the chain reaction and keeping cell damage to a minimum. However, even when you’re healthy, you need plenty of antioxidants to make sure you have abundant levels of immune cells and shield them from free radical damage.

Even if you resolve to sleep better, exercise better, and eat better in 2021, your immune system can still benefit from some assistance to reach optimal efficiency. That’s where astaxanthin supplements are known to be beneficial. Astaxanthin is a red carotenoid that is a potent antioxidant. In nature, astaxanthin is found in seafood such as wild salmon, shrimp, and lobsters, but its most concentrated source is a type of freshwater algae called Haematococcus pluvialis. In a human study comparing astaxanthin supplementation to a placebo, the participants who took the supplements for eight weeks showed a significant increase in immune cell numbers and an immune response's blood markers. BioAstin provides superior support and protection from oxidative damage and helps support an enhanced immune response.Astaxanthin’s biochemical structure is both water and fat-soluble, giving it the ability to protect the entire cell—both inside and out. And because healthy cell membranes are the basis of internal health, BioAstin provides powerful and effective antioxidant protection for the whole body. +
