why do you need to know The weather before exercise and after exercise.​

Answers

Answer:  

Exercising in hot weather puts extra stress on your body. If you don't take care when exercising in the heat, you risk serious illness. Both the exercise itself and the air temperature and humidity can increase your core body temperature. To help cool itself, your body sends more blood to circulate through your skin.

Explanation: Wind chill extremes can make exercising outdoors unsafe even with warm clothing. The wind can penetrate your clothes and remove the insulating layer of warm air that surrounds your body. Any exposed skin is vulnerable to frostbite.

Discuss why someone might use an alternative to long term care. Be sure to include some discussion of the Long term care continuum.

Answers

The cost associated with long term care may be a very valid reason why an individual might seek an alternative to this form of continuum health care service which provides a comprehensive Healthcare package.

The long term care continuum is comprehensive in the sense that it provides all levels of housing, supportive and heathcare services to beneficiaries usually persons who exhibit functional disabilities or are unable to provide self care. Long term care continuum makes provision for mental, residential health support , social support, assisted living, allocation of a skilled nurse for residential treatment and so on.

Inspite of the benefits attached with long term care, it isn't totally affordable and people may have to look at other Medicare plans to cater for their needs.

Apart from cost, eligibility is another reason why an individual may seek alternative to long term care.
