How to Improve Eyesight ????

Can we improve our eyesight on our own, or are we stuck with the quality of vision we have? Can exercises and other natural remedies help us avoid deterioration of our eyes with age? It’s a popular topic, and not without controversy. Opinions vary widely on the effectiveness of eye exercises, and no research has proven them able to, for instance, improve your prescription. But there are some exercises that certainly promote healthy eyesight.

5 Exercises to strengthen your eye muscles and improve your vision

1.Blinking

Blinking is an often overlooked yet simple way to keep your eyes fresh and being able to focus longer. Computer users and television watchers tend to blink less, especially when they are intently focused on something. Try it just now as a simple exercise. For the next two minutes blink every 3 – 4 seconds. After you have done this for two minutes, mentally take note of how your eyes feel, are they strained, relaxed, tired. Now try and not blink for 30 seconds at a time for two minutes. Do you feel any difference?

Whenever you blink your eyes are going into a brief period of darkness which helps to keep your eyes fresh and discharges previous information ready for new information, this helps to reduce eye strain.

2.Palming

This is done to relieve stress around the eyes and as a way to relax your eyes whilst taking a computer break.

Instructions for palming

1. Take a few deep breathes before you begin.

2. Make yourself comfortable whilst leaning forward on a desk or with your elbows resting on your knees. Close your eyes.

3. Place your two hands over your eyes with the cup of your palm covering your eyes, your fingers on your forehead and the heel of your hand will rest on your cheekbone. Make sure you can blink freely and you are not putting too much pressure on your eyes.

3.Figure of eight

This is to exercise your eye muscles and increase their flexibility. This is quite a simple exercise but a good one.

Imagine a giant figure of eight in front of you about 10 feet in front of you. Now turn the 8 on it’s side. Now trace the figure of eight with your eyes, slowly. Do it one way for a few minutes and then do it the other way for a few minutes. It may seem very alien at first but it’s worth persevering with it.

4.Near and far focussing

This is one of my favourite exercises as you can do it almost anywhere, I say almost as I couldn’t imagine doing it on the underground without getting strange looks from those around me.

Instructions for Near and far focussing.

1. Sit in a comfortable position, or stand, this will only take 2-3 minutes at a time.
2. Put your thumb about 10 inches in front of you and focus on it.
3. Now focus on something else about 10 – 20 feet in front of you.
4. On each deep breath switch between focussing on your thumb and the 10-20 feet object in front of you.

This will strengthen the muscles in your eyes over time and improve your vision overall.

5. Zooming

This is another one of my favourites as it is very easy and quick to do.

Instructions for zooming

1. Sit in a comfortable position
2. Stretch out your arm with your thumb in the hitchhike position
3. Focus on your thumb as your arm is outstretched.
4. Now bring your thumb closer to you, focussing all the time, until your thumb is about 3 inches in front of your face.
5. Now move your thumb away again until your arm is fully outstretched.
6. Do this for a few minutes at a time throughout the day.

This exercise will strengthen your focussing skills and your eye muscles in general.

How To Boost your Concentration Level ????

1.Get proper Sleep

Mind, like all the other organs, needs rest and proper sleep. You need to concentrate the most when you have something important to accomplish and depriving yourself of sleep at that moment would not be beneficial in any way. Get proper sleep and that will make your mind work with more concentration.

2. Exercise regularly:

Exercising and other physical activity promotes oxygen flow to the brain. This in turn makes the brain work more efficiently and boosts your concentration.

3. Work when the brain is more active:

It is said that 7 P.M. to 9 P.M. is the time when the brain is most active. Studies or things that require attention and concentration are best done at this time. Instead of indulging in television or other stuff, this time should be utilised in mind related work.

4. Simple exercises:

Simple exercises which indulge your senses to the maximum should be done to improve your concentration. For example, try to hear the sounds of small things around you even when you are sitting idle, try to count the stairs you use in a day and things like that. This will help to increase the involvement of your brain in every activity you do and hence will increase your concentration too.

5. Train your brain:

Like we train our pets, our brain can be trained too. You need to tell your mind every time, what your current work means to you and that you need to complete it well on time. Tell your mind what good things you would be getting if you concentrate on what you are doing and get it right. This way you can train your mind and improvise your concentration.

6. Eat good:

Eat foods that are light and nutritious. Your meals should be such that they give you energy and is a good fuel for your body but they should not be heavy. Try not to eat heavy food on days you need proper concentration with work or studies as heavy food only make you more lethargic and sleepy. Though it is recommended to eat a full breakfast, full does not necessarily mean heavy.

7. Take breaks:

If you expect your brain to work 24*7 or continuously for a stretch of time, then your expectationsare wrong at the first place. Take small breaks between works. Walk in the open air or listen to a song, take a power naps or whatever suits you better.

8. Avoid absorbing stress:

Stress is that big monster that ruins everything and leads to the formation of rust in your brain. When you are stressed out, you cannot concentrate to the best of your potential. Forget about the tension and do every possible thing to avoid stress when you need to concentrate on something.

9. Do one task at one instance:

When you open a plethora of tasks together, your concentration will definitely get hampered and you will not be able to complete any of them on time. Do one task at a time, and tell your mind that you will not jump off to the next thing till the time you are not through with what you are doing first. Multi-tasking, is not really healthy.

10. Yoga and meditation:

Lastly, yoga and meditation is an age old method practiced in Indians (and now worldwide) to increase concentration and mind power. Breathing exercises and yoga practiced in silent and clean environment, enhances your concentration abilities manifold. When your brain is at peace, it can work and perform better and this is what meditation helps you achieve. Yoga is not something practised now and then, but something to be practised regularly.

Psychologists say that a lack of concentration is something that is very common these days. Perhaps these tips can help you not join the crowd

How Much Sleep A Normal Human body Required ????

The short answer: adults need 6 to 9 hours per night. Around 7 to 7.5 hours of actual sleep (not counting time falling asleep and getting out bed) appears to be optimal for most people.

The long answer: it depends. The amount of sleep each person needs depends on many factors, including age, health, recent physical exertion, and mental activity. There is genetic influence, too. Some people just need more sleep than others and this runs in families.

Sleep is a vital indicator of overall health and well-being. We spend up to one-third of our lives asleep, and the overall state of our"sleep health" remains an essential question throughout our lifespan.

Most of us know that getting a good night’s sleep is important, but too few of us actually make those eight or so hours between the sheets a priority. For many of us with sleep debt, we’ve forgotten what “being really, truly rested” feels like.

To further complicate matters, stimulants like coffee and energy drinks, alarm clocks, and external lights—including those from electronic devices—interferes with our "circadian rhythm" or natural sleep/wake cycle.

Sleep needs vary across ages and are especially impacted by lifestyle and health. To determine how much sleep you need, it's important to assess not only where you fall on the "sleep needs spectrum," but also to examine what lifestyle factors are affecting the quality and quantity of your sleep such as work schedules and stress.
