If you've suffered an injury, getting rest is one of the best things you can do. Try to avoid any activities that require using the injured body part or putting weight on that appendage. The duration of rest will vary, but generally speaking it's best to allow the injury to rest for at least one to two days before trying to use or put weight on the injured appendage. Bed rest is one of the best ways to recover from a cold or flu. It helps the body heal at both the molecular and system-wide levels, and should be considered an important part of getting well after an illness. Most adults need between seven and nine hours of sleep each night, but if you're recovering from an illness or injury you may need even more sleep. How much sleep you need is also affected by your age. Newborns who are under four months old require 14 to 17 hours of sleep each night. Infants (between four and 11 months old) require 12 to 15 hours of sleep each night. Toddlers (one to two years old) require 11 and 14 hours of sleep each night. Preschoolers (between three and five years old) require 10 to 13 hours of sleep each night. Children ages six to 13 require between nine and 11 hours of sleep each night. Teenagers ages 14 to 17 require eight to 10 hours of sleep each night. Adults (ages 18 to 64) require seven to nine hours of sleep each night. Older adults (age 65 and older) require seven to eight hours of sleep each night. If you're feeling sick, injured, or just generally worn out with fatigue, you may need to get a better night's sleep. In addition to getting enough sleep each night, it's important to get quality sleep. Fortunately, there are several steps you can take to ensure a good night's sleep. Stay on schedule. Try to go to bed at the same time each night, and if you can't sleep after 15 minutes, try getting up and doing something relaxing until you feel sleepy. Staying on a regular sleep schedule can help ensure that you get a good night's sleep every night. Avoid caffeine, nicotine, and alcohol. Caffeine and nicotine are both stimulants that can take hours to completely wear off. And while alcohol may make you feel sleepy at first, it tends to disrupt sleep patterns throughout the night. Keep your room cool, dark, and quiet. Use blinds or thick curtains to block outside light from your windows, and try earplugs or white noise to help you sleep through outside noise. Manage stress. Don't dwell on what you'll need to do in the morning. Just write it down and allow yourself to disengage for the night. You can also try relaxation techniques, such as yoga, meditation, and tai chi, to help manage stress and keep you calm before bed.

Summary: Allow injuries to heal. Allow bed rest for illnesses. Ensure that you get enough sleep. Get a good night's sleep.

Being INCOSE certified will increase your job prospects and advancement opportunities. To get certified, you'll need to pass an exam and meet minimum education and experience requirements. There are 3 levels of professional certification: An associate systems engineer professional (ASEP) simply needs to pass an exam. A certified systems engineer professional (CSEP) needs 5 years of experience, a degree, and 3 professional references. They also need to pass an exam. An expert systems engineer professional (ESEP) needs 25 years of experience, a degree, references, and must be in a leadership position. Instead of an exam, they must pass a panel review. A senior systems engineer is the next step after entry-level associate and junior positions. Beyond that, a chief scientist or chief scientific officer oversees all aspects of an organization's research or technological operations. To maximize your income and experience, always be on the lookout for new opportunities. While there are more systems engineers working in the private sector than in the past, governments and militaries drive the demand for systems engineers. If you want to focus on defense and aerospace engineering, work for the government, or work for a government contractor, you'll likely need a security clearance. You'll need a conditional job offer that requires clearance in order to apply with your nation's state department or other appropriate agency. It will take some time to land a job with an employer willing to sponsor your application. If you're up for a job against someone who already has clearance, chances are high the employer will go with your competitor. Regardless of your industry, scientific and technological advancements will change it over time. Stay up to date on advancements in your industry by going to conferences, seminars, and other professional development opportunities. Take courses on new computer programs, manufacturing processes, and other emerging topics that impact your field.

Summary: Apply for an INCOSE certification. Look for senior systems engineer and chief scientist positions. Get a security clearance. Stay current with advancements in your industry.

One symptom of Lyme disease is a rash, called erythema migrans. This rash starts at one point and expands out, sort of like a bull's eye. It may appear as soon as 3 days after being bitten, but it could take up to 30 days. It will likely start around your bite, but as the disease progresses, you'll see it on other parts of your body. One of the issues with diagnosing Lyme disease is the symptoms are similar to many other diseases. Mainly, they are similar to flu-like symptoms, such as chills and fever. You might also feel achy or have a headache. You may feel lightheaded or dizzy. Sometimes these symptoms are accompanied by nausea and vomiting. You may notice your joints are achy, and they may swell as well. Usually, this symptom will appear in your larger joints, such as your knees and elbows. Also, you may have a stiff neck. You may also have shooting pains in your body. Complications of Lyme disease can lead to heart issues. You may notice shortness of breath, as well as heart palpitations. These symptoms may be accompanied by chest pain. Another symptom of Lyme disease is partial face paralysis. This symptom is neurological in nature. Other neurological symptoms include meningitis (brain swelling), as well as numbness in your arms and legs. The main symptoms of meningitis are fever, low energy, and loss of appetite, though you may also have light sensitivity, a stiff neck, and a headache.
Summary: Check for a rash. Look for flu-like symptoms. Pay attention to joint pain. Notice heart issues. Watch for facial paralysis.
