How to live a happy life? The following suggestions may be of great help to you.
Keep positive. 1. Optimists have a 35% less chance of having a heart attack or stroke, are more likely to eat a healthy diet and exercise regularly, have stronger immune systems and even live longer. If you face a challenge or obstacle, you’re more likely to see it as a temporary or even optimistic thing, allowing you to learn and grow.
Start volunteering. 2. It can reduce the risk of cognitive (认知的) disorder. It can even help us live longer. Even if you have a little time to offer, just the act of giving has been shown to improve your health, possibly by temporarily reducing your sense of pain.
Be grateful. Counting our blessings protects us against anxiety and depression and boosts optimism. One of the best ways to make thankfulness a part of your life is to keep a journal. 3. Keeping gratitude and recording your good deeds may help you live happily.
4. People who are more socially connected to family, friends and community are happier. They’re physically healthier, and they live longer than people who are less connected. High-conflict marriages, without much affection, turn out to be very bad for health, perhaps worse than getting divorced. 5.
A.Eat healthily and happily.
B.Strengthen social connections.
C.Looking on the bright side of life is really good for you.
D.You can set down some positive experiences in your diary.
E.Instead, living in good relationships is beneficial to health.
F.Studies show volunteering can reduce stress and depression.
G.You’ll have no time to volunteer and give thanks in your life.
The other day, I bought an expensive anti-aging cream that promised to make my face look several years younger that other women by fighting free radicals. It made me curious about what free radicals ares.Is the anti-aging cream the only way I need to protect myself?
“As a scientific term, free radicals are essentially unstable atoms, “says Arizona-based doctor, Natasha Bhuyan, M. D. “In medicine, they cause cells to break down over time and are linked to aging.”
A super simple chemistry review for you: Atoms from different elements are the building blocks that make up water, nitrogen and more. Electrons (电子) are the negatively charged atoms, and they like to be in pairs. When an electron loses its partner, it creates a free radical, which is usually unstable and highly reactive. Free radicals typically go through the body to seek out a replacement for their missing electron, and that can result in damage to cells,proteins and DNA.
So how do free radicals form and why do they happen? Bhuyan says, “Scientifically, free radicals are unpaired electrons that are seeking a mate to bond with. The theory behind free radicals is that they can lead to the imbalance between free radicals and antioxidants (抗氧化剂).” Another mini-science lesson for you: Antioxidants are natural or man made matters that can help delay or prevent some types of cell damage. They’re often found in fruits and vegetables.
A lot of the aspects of modern life — our diet, lifestyle and environmental factors like pollution, can cause oxidative stress. Over time, oxidative stress weakens cell and tissues and can leave you more easily to certain health issues including cancer. And, as beauty marketers are keenly aware,oxidative stress can also speed up the aging process. Now that your know free radicals can weak on your health, you’re probably wondering if there are any ways to prevent them from forming or at least to minimize their negative effects.
