Viruses spread easily through contact with infected bodily tissues, such as saliva and urine, semen, vaginal secretions or pus. Bacteria are often spread via direct contact with contaminated surfaces or objects.
Viruses can get into our bodies through cuts and scrapes on the skin, bites, and other injuries. They can also be transmitted through the eyes, nose, mouth, ears, rectum, and anus.

How to lead a healthy lifestyle
We live in a fast world where we don't get enough sleep, eat too much, drink too much alcohol and smoke cigarettes. We don't take care of our body's health properly.
If you are working full time, it can be difficult to keep a healthy diet and exercise regimen. Stress makes it even more difficult. Our minds tell us we can't handle this situation any longer so we feel guilty and give in.
It is possible that your body is experiencing problems. Ask your doctor for his/her opinion about your current situation. If you find nothing unusual, it could be stress from your job.
Some people think they're lucky because their jobs let them go to the gym on a regular basis or they have friends who help them stay fit. However, those people are really lucky. These people have no problems. They control everything. I wish all people could do the same. Unfortunately, many of us don’t know how to manage our personal and work lives. Many people end up with bad habits which eventually lead to diseases such as heart disease, diabetes, cancer and many others.
Here are some tips to help improve your lifestyle.
-
Get 7 hours of sleep minimum and 8 hours maximum each night. This includes proper sleeping positions and avoiding caffeine during the last hour before going to bed. Caffeine blocks melatonin hormones, making it difficult to fall asleep. Also, ensure your bedroom is darkened and clean. If you work late at night, make sure you have blackout curtains.

Eat healthy. Have breakfast every morning. Sugar products, fried food, processed foods and white breads should be avoided. Include fruits, vegetables, and whole grain for lunch. Afternoon snacks are recommended to be rich in protein and fiber, such as nuts, seeds, beans, fish and dairy products. Avoid sugary snacks like cookies, chips, chocolates, and cakes.

Get enough water. The majority of people don’t drink enough water. Water helps us to burn more calories, keeps our skin looking young and supple, flushes toxins from our system and improves digestion.

Dehydrated is yellow, orange dehydrated slightly; normal pink urine; overhydrated red urine; and clear urine indicates highly-hydrated.

Exercise - It has been proven that regular physical activity can improve energy levels and reduce depression. Walking is a simple exercise that can improve your mood. Even though walking looks simple, it requires effort and concentration. Your brain must be able to concentrate on walking, while taking deep breaths and slowing down. A 30-minute walk for 100 to 150 calories can be burned in 30 minutes. Start slow and work your way up. Stretching after exercise is important to avoid injury.

Positive thinking is vital for mental health. Positive thinking creates a positive environment within ourselves. Negative thinking can cause anxiety and drain your energy. To stay motivated, try to think about the things that you want to accomplish. If you feel overwhelmed with all the tasks, you can break each task down into smaller steps. You will fail occasionally, but you can always get up and try again.
-
You must learn to say No - Too often we get so busy we forget how much time is wasted on things that are not important. It is important for you to know when to say "No" and how to do it. Saying 'no' does not mean being rude. Simply saying "No" does not mean you are rude. There will always be another way to finish the job. Be clear about your boundaries. You can ask someone to help you. Delegate the work to someone else.

Take care to your body. Keep an eye on your diet. You can boost your metabolism by eating healthier foods. Avoid eating anything heavy or oily as they can raise cholesterol levels. You should eat three meals per day and two snacks each day. Around 2000 to 2500 calories should be consumed each day.

Meditation is an excellent stress reliever. Relax your mind by sitting still with your eyes closed. This will help you make better decisions. Meditation can help you be calmer, happier, and more productive.

Do not skip breakfast. Breakfast is the most important meal of each day. Skipping breakfast can lead to eating too much lunch.
